Received this week my first attempt at a deep V petrol powered offshore mono.
Subject to the build success and the tuning, handling i intend racing her in Omra D series later this year.
Thanks so far to Martin and Danny for their advise, i hope theres plenty more where that came for, and the rest of you!
So far i have flatted back most of the hull and started painting her in a dark blue silver fleck, drilled out the rear engine hatch and prop tube.
Met with my vinyl sticker man today and agreed on the sponsors etc. But thats a secret until the next installment.
Tomorrow the engine bracketery etc.
Regards
Simon

Ooooh, I like, I like ;D
Hope your graphics are nice and bright, blue metalflake I can see on the bank, but at 100 yds ??? (even though it won't be me "challenging" you) ;D Still you're not going to stop, are you ;)
Are you side mounting the engine? Its a good way to get the pipe central, just don't forget the balance side-to-side as well. Wish I had that amount of room in mine!
Good luck, and we're always here for advice (some of it may even be worth listening to) ;D ;D
Danny

Did not get a chance to do any work on the Makara yesterday as it was wifeys birthday! :'(
Back on to her today with avengance. ;D
Engine glassed in and mounted, prop tube bent and installed, skeg and rudder bolted on and top sides painted.
Oh and the electrics box mounted.
A pretty good day i think! ;)
Any ideas on how the throttle linkage set up works, is it a bar thing or one of those bike brake thingy's. ???
Regards
Simon

Your engine mounts look fine, but you have too much unsupported flexi showing. As the engine moves around whilst running, it will set up oscillation in the flexi which will increase to a point where it will snap or twist up the inner. You need no more than 15mm MAX between the end of the outer and the engine collet. Have you the rest of the outer you cut? If you have, find a short piece (25mm) of tube that will fit snugly over the outer then JB weld or solder it together to extend the tube. The PTFE liner will need to be replaced with a full length piece for the new length.
Sorry, mate - but better to tell you now, than you have a broken flexi trash the inside of your boat!
For the throttle, is the carb lever a front to back motion or is it at an angle. If it's straight, I would use either 1.5mm brazing rod or 2mm bike spokes (stainless). If it's straight but at 90 deg, you can use a bell-crank (like in your other). I know a few with sparkies who use 'bowden' (brake) cable but there is usually some slack in the set up which can cause throttle inconsistency. Also the type I once used (never again) rusted up and kept jamming. You also need a spring to pull the throttle lever back (bowden is great for pulling, but useless for pushing) which means that there is a constant load on your throttle servo.
Who said it was going to be easy - the best things never are ;D
Danny
-
Danny,
Thanks for the post, i would prefer to know now, rather than later. I have still got the tube so i will refit it, ta.
As far as the ptfe liner, i havn't got one. Its a bit like a pxxxk in a bucket. I will get onto Prestwich and see if they can send me one today.
Would you suggest strapping/mounting the top end of the prop tube to save any movement as well, i have glassed it in at the other end?
Regards
Simon
-
You don't need the PTFE, some people run with it and some without. As long as the shaft is lubricated you will be ok.
You will need to fasten the tube at the motor end as well. Make a bracket from som ply.
Looking good otherwise ;D
-
I suppose the shaft liner depends on who's shaft you buy. I've never trusted steel rubbing against brass (even with lubrication) so I buy Aeromarine ones which have a liner (mine look and feel more like polythene than PTFE though).
Ian's idea of a ply bracket is good. Anything to stop movement of the outer. I normally just use P40 but my shafts are a lot lower than yours (smaller engines) so yours would need a great blob of P40 :o
Double linkage to rudder, eh. No excuse for poor steering there then ;D
Love the SHINE on that rudder 8), bet it doesn't stay like that ;D
Danny
-
Here's a stuffing tube holder and a throttle setup using pushrods. Do NOT use heavy pushrod for the throttle as it can cause fatigue in the carb if it doesn't have some give in it.
-
Ian,
I dont suppose you have got a close up of throttle linkage of the Zen on the bench.
That set up looks perfect. Is it commercvially available?
Regards
Simon
-
It's a simple bellcrank fastened to a bit of aluminium bolted to the front mount, a couple of ball joints and a pushrod. There are systems like this available but it is just as cheap to buy the bits and make your own.
I felt the bellcrank was a little weak so I drilled out and bushed the circular servo disc you see in the first picture. Altogether a more robust setup. I use the shrink tube to hide the rust on the pushrod as we boat in salt water ;)
-
Sad news i am afraid, just spoken to my sticker man and they are not going to be ready untill next Wednesday, gutted! :'(
Just have to wait a bit longer.
Steering and throttle cables turned up today from Prestwich so in the garage tonight! ;D
Danny, just saw a picture of your boat with twin fuel tanks, are they ajoined and if so are they commercially available? I have been looking at my big yellow 1 litre tank and its mounting. To clear the prop tube i have to mount it over the top! Not good me thinks, centre of gravity and all that fuel sloshing around.
Regards

Hi Simon
My tanks are all Prestwich. They are 1 piece with a groove in the top for the tuned pipe. Have a look at Dave's website, tanks are on the middle of the opening page.
I use the PT3A but I must admit - the NEWEST is 15 years old :o :o
(They still bear prop grooves from when I did multi racing).
They are expensive but dead easy to mount and last forever.
They are not used much in D class as the petrol boats don't use anywhere near as much juice as the glows. My 'A' class uses 1.5 litres in 33 mins (good job the races only last 30 mins) ;D
Most of the D's use the smallish aircraft type tanks, or a few make their own from tin which is soft solder joined . I would have thought your 1 litre would last at least 30 mins.
There was some talk of using IV (blood) bags. Quite a few of the World Champ competitors use them. Very low, and apparently OK for petrol (not methanol, though) :(
For information, here's my 7.5cc one

Good luck
Danny
-
Guess who turned up today? ???
Sweet! :-* :-*
Engine ready to go, electrics ready to go, fuel tank to be done, exhaust on order.
Ready for the water in two weeks.
;) :D ;D
-
Very smart, Simon! Now, as long as you don't drive like David Coultard............ ;D ;D
Danny
PS Off to Torquay this Sunday, so if you see on the news that a model boat is attacking France, you know I've gone off course ;D ;D
-
Nimrif's Makara looks amazingly similar to the AeroMarine Challenger series of hulls. Wonder what would be the result of a head to head between two equally matched boats?

Hi there 2772e, with luck there will be some photo's here both of the throttle linkage, which uses a straight pushrod from the servo onto the bellcrank, nice and simple, also an IV bag fuel tank.
So far so good.
Sorry they are blurred.
Glenn
-
Cheers Glenn,
In the end i went with a cable and a plastic 1 litre fuel tank in between the servo box and the motor.
Should be on the water this weekend with any luck so will see how we get on.
Thanks for the pics.
Simon
-
no problem Simon,
good luck with it this wekend. Mines ready to go now, if I ever manage to tear myself out of the house I may get round to getting some retesting done on it. Hoping to run mine at Windermere for a one off this year.

Maiden voyage over yesterday, and a success even if i say so myself.
No rudder adjustment, runs straight.
No leg adjustment, gets up and planes just right
Just need a bigger lake and some buoys to get my eye in and we will see how she goes.
Another 1 litre of rich mix and then we can start the tuning and fun bits.
Offshore i think she will need some more weight.
Only problem was the batteries went flat, so could not try her with the top on. One more weekend before my fist race at Stevenage, no pressure.

Thanks for all the help during the build.

Nice maiden, looks comfortable on the water ;D
-
After a week of tightning down and finding a lake i could run a petrol on, big enough and local enough.
2nd trip out to Brentwood Model Boat Lake last weekend.
Engine running in and engine tuning.
a few final tweeks and screw her bacjk together and we should be raedy for the fist race this weekend.
At least i know now she flies as well as she floats.

Now that I've eventually met him, Simon does not seem the type to blow his own trumpet, so I will blow it for him!
His Makara took part in it's first race at Stevenage yesterday and he had a quite eventful day. The race he was in had quite a few very experienced drivers, he drove safely and his boat performed extremely well. The handling was stable and the speed was more than acceptable - it was bl**dy fast :o ;D
He would have probably been in with a placing but for a slight problem with the radio (box mounting re-design, I think).
Anyway, the purpose of this post is to inform you all - Simon included (he had to leave early, so I don't think even HE is aware yet) - that his boat won the Concours de Elegance trophy for the BEST turned out boat of the day.
Having read back through this thread I think that Simon's is a remarkable achievement, given it's his first OMRA boat and his first outing.
So - well done Simon!
Danny
-
Very impressive boat. Nicely turned out.
She does fly well !
Richard ;)
-
A big thank you to everybody for their advice on building the boat and setting her up, without it i would never have made the first race.
It was nearly a success yesterday, turns out the two bolts that hold one side of the electrics box had shaken loose and i lost steering on a buoy, she spun stalled and started to disintegrate. (should have used lock washers!) Thankfully the lid floated (glad i put that polystyrene in at the last minute) and all the pipe lagging distributed all over the lake! Sorry chaps!
Glad she did stop though, on closer inspection the petrol tank must have touched the exhaust and petrol was squirting out. Ideal ingredients for an accident! Thats irony!
Back to the garage this week for the rebuild, a bit more testing on Saturday and hope to see you all the following week at Kingsbury!
Regards
Simon
;D ;D
-
well done on your first race simon she goes real nice mate,looks great too.as for the pipe lagging zip ties work well to hold things together and in the right place ;).mine are that tightly fitted between the bulkheads they dont move.its a good idea to fasten them to the engine somehow in case your boat disintegrates in a crash also ,that way the engine will be suspended by the foam and wont sink.
-
I have now completed the second race and managed a first in my heat and 2nd overall. Quite pleased with that although my legs did not stop shaking throughout the whole race.
A couple of testing pictures on the water
-
Well done mate she looks great in the pics how fast is she now have you had her clocked?.have a look at this new zipkits woody similar to mine in design with a mildly modded zen.looks scary fast but needs trimming in this was its first outing ;D ,im saving for a zen for mine now!!. ;)

Hi all i ordered a makara last week and a sikk 27 to go with it, i cant wait but there is a couple of questions id like to ask.
1 how far back to mount the motor and 2 how far up the transom would you exit the stuffing tube?
i intend to race it at windermere in sept so when the hull comes it all hands to the pumps to build her, run her in and get used to her.
i have built one gas boat before but its not up to omra spec its an arrow shark flying dragon with a g260 zen in it.
did you load everything into the hull as a dry run and move the motor to get the c of g?
any help i can get with this build would be very welcome indeed..........cheers..........Pete.
ps i will be D 101 sounds good that ;D
-
Hi Pete,
I will probably upgrade to a Sikk over the winter.
As far as the C of G i found the best position was about the same length as the flexi tube, also made for easier fixing and no cutting. She seems to run well and i have a 2nd and a 3rd this year.
Stuffing tube as low as possible, any help would be happy to oblige.
Look forward to seeing you at Windamere.
Regards
Simon
-
thanks simon and that pic is awesome ive allready set it as my wallpaper on my pc.
i will be picking your brains again if thats ok ..........cheers ........Pete
-
Pete,
If you pm me your email address i can send over some hi res pictures. Will look better on a desktop.
I am honoured!
Regards
Simon
-
hi Simon thanks for the info and as soon as i get my hull off paul ill keep you posted on the build and put it on your thread if thats ok.
i should get the hull next week all being well.
i would love the high res pics (that boat is superb) and my email is peterhetherington@hotmail.com ..........cheers.........Pete
-
oh Simon one final thing im having my hull sprayed yellow in 2 pack and i want my boat in the DeWALT sponser theme, i need three big DeWALT stickers, ive searched the net and come up with nothing.
where did you get the red bull stickers for yours they look great and really set the boat off........cheers...........Pete
-
Hi Pete,
I had them made by a local sticker man. if you want i can give you his details but he can be unrelaible. If you look on the OMRA website under suppliers i think there is another chap that can do it.
Alternativly google stickers or decals in your local area?
Regards
Simon
-
thanks Simon i got your pics which are superb and that nikon that took them is one hell of a camra.
the stickers are sorted because i am mates with a local sign writer and saw him today and he said he can do them for me free,
i like that word free (he owes me one) :).
yeah about paul i dont know him ive only had one dealing with him and thats for my makara but ive talked on the phone and he seems a real sound guy,+ he leaves the hulls in the mold for nearly a week to cure them then there's no hooks in the hull.
cheers...........Pete
-
hi again Simon got my hull today so on with the build.......Pete
-
Hi Pete,
Good news, how are you mounting the engine?
Regards
Simon
-
on 5" marine ply rails which glassed in will allso beef upthe bottom of the hull.........Pete
-
hi pete good to see your hull arrived ill look forward to seeing it come together,by the way just ordered a zen off dave so deciding which boat it will go in.either my woody or i may build a cat from scratch ;D.will be running a clutch but not decided wether to run a water pump or not,seeing as ill only be using the clutch for easy launching on my own and for bringing the boat to shore seems i might not need one.its a long story but i got two zens from a guy i know cheap and some **** broke in my workshop and stole them along with my tools.had to get insurance to pay out so i ordered two zens off dave but i only need the one.should have them pluss headers and mounts clutch etc in next week or so.might try it in my boat while i decide which new hull to build.you running a clutch in this new makara?.
-
Pete,
Have you bought or are you making the rails?
If you are making them please keep a copy of them?
I can see a rebuild on the cards over the winter.
Did you get the Sikk ffom Bluefishy78?
Regards
Simon
-
hi Simon i did get the sikk from barry and the rails are gonna be made out of 6.00 marine ply (not got yet) the mum inlaw's just died so things will have to be put on hold for a bit..........cheers........Pete
-
hi again Mart id never run a clutch and pump im just going for a straight drive right through and i got shut of my starter too.........cheers............Pete
-
thought so mate but as you know i dont race my boats im just in it for the fun of it,my lads made up cos hes getting my old weedy boat when i get the new one built ;).once i get it done we need to meet up and have some fun ;D.
-
hi Mart as soon as i get Al's radio box done im gonna start my new build on the makara and what a big hull that is its awesome (for me anyway) cant wait to get started.
by the way this IS a radio box ;D
-
hi pete thats one top box mate superb work of art
-
hi Mart as soon as i get Al's radio box done im gonna start my new build on the makara and what a big hull that is its awesome (for me anyway) cant wait to get started.
by the way this IS a radio box ;D
looks more like a lunchbox ;D and to top it all its plastic ;), too neat for me too lol.my new zens should be here this week ! will need to build a boat for one of them though probably the 50" cat.heres a pic of one like it.
-
well i started my build today here's how its looking
-
Hi Pete,
Boat is looking good, are you still going with the Yellow paint scheme?
Don't you just love them when they are all shiny and clean, are you sure you want to race her. Looks too good. ;D
Have you raced Omra D before?
On a serious note i see you have fitted turn fins, i don't run them on mine, just reduced the rudder throw to 80%. She seems to turn OK. I don't run with trim tabs either.
:P
If you have not already got a pipe, i have a mate around the corner from me who builds them, very good, competitive and keenly priced?
Looking forward to racing with you at Windamere. ;)
Regards
Simon
-
hi Simon ive never raced before but ill give it a go.
the pipe ive got is a quiet bonzi pipe which puts another hp on it.
i do intend on the yellow paint but im gonna run it first then just take the hardware off the back and mask up.
what radio are you running? ive still got a jr 40meg wheel set.
i should be doing the first rud this coming sunday at sale water park........cheers.............Pete
-
Pete,
I am running a Futaba 40 digital set, it has a ten model memory and i also use it for all my land based models, cars and boats etc.
If i was going to look at new i would go fot the 2.4 sets, no clashes and the prices have come right down. I prefer sticks to wheels but its personal choice.
You have picked a fast set up to start with.
Hope she runs well, dont get tempted to over rev it when shes breaking in.
Regards
Simon
-
the break in is gonna be very boring :( and ill set
it rich.
how many tanks before i can tune do you reckon?
and also i hate trim tabs on my previous boats they have caused me nothing but grief but turn fins (duck slicers)as me and Al call them stop the boat from spinning out on the corners, they work really well for me..........cheers..........Pete
-
Pete,
Last time i was talking to bluefishy, it was about 2 1/2 litres and no more than 1/2 to 3/4 throttle.
1/2 throttle for the first tank and then build it up 20/1 on the oil and then 25/1.
To be sure check with them, if you want the engine to perform and last.
Regards
Simon
-
id stick to 20-1 oil mix if you want your engine to last ;),i wouldnt listen to a word fishys tell you either ;D.
-
barry is ok he sponsers kurt and ive met kurt he,s a really nice guy and he race's in omra and i listen to his advice so this makara is the setup he uses on his apache and he will be advising me the first time out because he will be there.............Pete
-
hi pete yes listen to kurt you wont o far wrong makara looking good, you will have to put some of my razor on...
-
That was a joke Pete ;) ,but id still stick with 20-1 mix some even use 16-1 in the states.more oil wont hurt it but not enough will cook the motor.
-
i use 20>1 on my zen so ill stick to that on the sikk aswell............Pete
-
started my radio box tonight this one will fit my butties in and a spare justadda plus a spare motor ;D.
it's big but that means i can put everything just where i want it..........Pete
-
sorry that was a bit blurred so here's a couple more...........Pete
-
thats alot clearer looking good plenty of room to carry a spare justa bout anything he he he ;)
-
Pete hope mr watta hasnt been giving you a hard time again? ,anyway nice box ;D wheres mine? .By the way did you offset your driveline on this build or is it dead centre?.
-
sorry pete its been moderarated but as you know its out private joke and no one was offended,so here it is refrased, looking clearer and there is lenty of room to addwater,or is it room for a left hand man ,and there is even a bit of space left for lateRon he he he ;)
-
ha ha ha ha we start again.
but the build is comming on fine that makara is gonna fly..........Pete
ps ill save the last bit of the box for later ron..........cheers........see you later
-
hi simon.that boat of yours is nice ,looking fortward to racing with you again soon,was hoping to of seen you at brynbach for the 1 hour race,good day,keep that boat of yours looking pretty,all the best mate kurt
-
yes simon nice boat doing a makara my self but have done my back a the moment so i lent pete the parts so he could get on with his whilst his parts crawl there way the the c**p postal system we have here in the uk.............alan
-
they will be here SOON al
-
no rush pete youknow that ............al
-
hi pete.get that boat of yours done so that i can set it up for you,kurt
-
DO YOU GET GOOD COMISSION ON THESE MAKARAS AND SIKKS THEN KURT LOL ;D,just kidding fella ;).
-
i wish, >:(i am doing this as a favour ,i will help anybody out as those that know me will tell you.and since it was me that have shown some poeple who want to see what a sikk goes like,and the boat i use is a cobra gt 51",took best boat at weymouth,
-
well Kurt you certainly got my boat flying that time at birkenhead and you saved me loads of money and time by lending me about two hand fulls of props to try and we had a great time doing it.........cheers........Pete
ps ive had a nasty abbsess under my tooth but its sorted now so i will continue with the build again tomorrow
-
always willing to help anybody out pete,and getting the most out of a boat is what i like to do,its nice to see a boat run as it should do,and lending yopu a few props dont cost nothing mate,looking forward to seeing you soon with your new boat,will be a good day on sunday all being well,,,,,,,,,,,,,,,,,kurt
-
all being well it will be ready on sat, so see you on sunday...........Pete
-
simon.next race is not on due to there being to much weed on the lake.or so the rumor is mate,so check first,gutted really.was looking forward to another bash about.ha.ha.will try and lat you know more when i hear more,,,,,,,,,,,,,,regards kurt
-
Thanks Kurt,
Would not mind an extension of some help with mine as far as props go sometime. Where are you?
Reckon if you can get me a good deal on one of those motors i will rebuild over the winter.
looks like 2008 is going to be a good season.
Word on the street is that there are alot of people quitting becasue of politics so not sure how many races there will be next year?
Regards
Simon
-
hi simon.im in chester mate.but we go to sale in manchester on a sunday to test mate,as far as props go mate,no problem there,you can try what ever i have got mate,i have a few ,2 and 3 blades,i even have a 4 blade chop prop as well,we are trying to sort out a race at our lake for next year mate,i know theres a few dropping out but theres also a few new members as well,as me and you both know,i will see what i can do for you mate over the engine,next tinme we meet at a race just talk to barry who will be there with us,and i will put a word in,having abit of fun with martin no1 fan at the moment,he does not like the sikk engine???still,i know how good they are and so does most people who have seen my boats go,enjoy your holiday mate and if theres anything i can do to help let me know,regards kurt
-
Hi Kurtt its not that i dont like the sikk its i read bad reviews on it, things wearing like piston liners and bolt lugs breaking etc.also materials not been as good as the zen?.I just feel safer spending hard cash on a zen knowing its quality rather than take a risk on a copy sorry.Maybe the new sikks are better ,seems your having success with it .anyway im in abd mood just ruined the heads on to of the mounting studs on the stock zen mount plate behind the starter.i was trying to remove it to fit the new mount plate i got from dave.looks like they overdid the loctite and now ill need to dremmel a slot in the head see if they will come out :'( ill see if heating them a bit with a soldering iron will loosen the buggers. >:(.might need to rethink the front mount too as im not sure it will fit between the clutch and the motor dont think the clutch will reach the shaft then :-\.all help glady recieved before i throw this bloody thing through the window >:(.
-
hi martin,should of bought a sikk,comes complete with all mountings and rubbers and throtle linkage,bolts straight in no problem,,,,,no sorry mate just getting a dig in,can you pm me your home number so we can try and sort out your problem,as i am having trouble trying to understand what your problem is,if ican help i will,regards kurt
-
kurt the avitar of the cobra looks well O0
-
and where is yours Al ;D

Hi mate its sorted,it was the ali plate thats on the enginie under the pull starter i needed to take it off to put the motor mount on.i ruined the head on the stud trying to remove it.iIhad to cut another slot in the head then a tap with hammer and screwdriver and out they came.now i need new studs .Ill get stainless this time these were cheap crappy ones.I heard the sikk mount was crap too ;D,i got a nice blue anodized mount with coil relocator bracket.Now i need to figure the best way to fit the front mount as im running a clutch.I dont like the idea of putting it between the clutch as that will bring the clutch 1/8" further from the shaft.any ideas lads?,and i want the clutch so no wise cracks about ditching it thanks ;).
PS THANKS FOR THE OFFER KURT.
-
glad you sorted it out as for the front mounts and clutch i am not to sure what will be best,i dont run a clutch,so dont come across this problem,running the clutch a 1/8" out should not be a problem mate as long as the clutch is still seated inside the bell housing ok,you will have to check it mart,oh,and i am looking into that other little thing you asked me about,someone else has also asked me to help them find out as well,this should be done hopefully by tonight,,,,,kurt
-
Cheers mate i got the guys number and apparently hes emailed the guy today so hopefully its sorted,bet the other guy who asked you was dm? ;D.ill keep you posted as to the outcome ;).
-
hi mart is that zen going in your woodie if yes will it be done for weekend so you can get down to sale on sunday....not been chucked of here yet........he he....al ;D
-
hi mart is that zen going in your woodie if yes will it be done for weekend so you can get down to sale on sunday....not been chucked of here yet........he he....al ;D
No its not going in the woody i gave it to my lad (woody),im planing to build a cat (woody) unless a little deal im trying to do comes off then its going in a glass mono 45" long.same as this one.
-
hi mart your better off with a mono those cats are always upside down.....
-
hi mart your better off with a mono those cats are always upside down.....
Well hopefully ill get this one and build the cat later ,the mono has a hatch too so all been well it should look real nice .ive been planning the cat for a year now but this hull came along so ill see what i can sort out O0.
-
Ive always fancied having a cat but every time i say right i am going to buy one i see loads of vids of them flipping so it puts me off, any way this is my lot not the razor 45 and the makara i will stick with these till they end up written off racing in omra as a lot do
-
bo***cks Al box clever and NEVER wright one off you know where im coming from O0............Pete
-
somrtimes its hard not to smash a boat up.as i found out with my first cobra on its first race,got T boned in the side and ripped the hull right open,almost split the hull in 2,not nice.not nice at all.omra is all about staying out of trouble and trying to finnish the race in one piece,but sometimes that is hard,bloody hard,as you will find out,still,its all part of racing,and if you understand that and dont get upset when your boat comes home in bits then you will go along way,most of the time you can stay ouit of trouble,and all boats can be fixed,,,,,,,,,,,,,,,,,,,,,,,,,,,,kurt

Looks like i got that hull all i need to do is decide on a colour ,white ,black ,purple, red,grey,green ,mid blue ,dark blue,lite blue ,yellow or orange hmmm ? ::).Ill be doing a build thread as soon as i get the hull O0.Al not all cats are unstable in fact a mate who has one reckons his is better than all his monos put together and he has a few including the puma from prestwich.
-
I'm not saying the are all unstable its when that bow gets bounced up high when it hit a high wave or a bad bit of wake, there is a lot of area for the wind to get hold of thus flipping them, that what i don't like about them.go with orange and you can go with the i've been tango'd theme...al
-
by the way this boat has steps in the hull so its nto classed as a mono for racing i think or so ive been told.
-
its got 2 or more inch of free board so run it in d class in omra..
-
whoo hoo finely got the boat done but no paint as yet but very runnable............Pete
-
well done mate pick you up 10.45 raining or not im going let my know if you are as well
-
floatation ? :o me thinks you need some more!!looks good though but a bit bare in that hull id say you need at least one more zen in there ;D.
-
yes pete i think you need that other length of pool noodle i have, and believe me mart on sikk in one makara does the trick they fly........al
-
what sort of speed we talking 50 55? id say two youd get 60 pluss but doubt the boat could take it lol ;D.
-
50 to 55 will be good its not about speed in omra its about finishing, annd knowing when to back off the throttle, its all to easy to end up t**s up,and that does not win races
-
yep i think i do need more floatation Al bring it with you and ive got kurt's pipe cut too oh i cut vents in my hatch now so if it's p***ing down i can run with the hatch on and ive got the fishing brolly out see you later
-
no problem will bring noodle in a bit
-
upside down is the way i do it all the time,and still get the points,slowing down is for wimps,rain good today,still going to play.loading up now ready to go.rain or not,just look out for the idiot all in yellow wets,that will be me,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,kurt oh pete,boat looking good mate,really good,wel;l done mate,see you in a bit,,,,,,,,,,,,,,,,,,,,,,,,,,,,
-
did it run ? video ? ;D .
-
rained,did get boats running only 2 went in,a few problems but all will be sorted,check out new thread on chitchat(mistakes we make)alans razer looks better than in the photos,a really good built boat,petes boat was goood,nothing that is nt going to be hard to sort out,2 weeks time retest again,hopefully better weather,and more run times......................................
-
did it run ? video ? ;D .
sorry no vids not Worth chancing the camera in that fine rain you know it gets you wetter than the normal stuff,but we will be back there in 2 weeks and if weather is better the vid cam will be out, kurt cobra is an eye opener hope you can make it over in 2 weeks mart youll love it..al
-
AL it didnt rain here all day ;D,didnt run today though wifey had me lowering a ceiling despite my protests ::) >:(.,ill look forward to some video of you guys running.why 2 weeks time whats up with this week ?,ill need to settle for seeing the vids of your boats im afraid as i dont drive so all my boatings done close to home.
-
LIKE YTOU MATE I HAVE A WIFE AND SHE HAS PUT CLAIMS TO ME NEXT WEEK END...AL...sorry for the shouting
-
Pete,
Is the Makara finshed yet?
Regards
Simon
-
yep its been put together and been out with it twice got to bring the nose down quite a bit because when i open her up there's only the prop in the water and very unstable it looks good though, so i think im gonna have to put, dare i say the word trim tabs on it. :'(
i can tell now she's gonna be one quick boat ;)
the last time a ran her i was with Kurt and it got a plastic pint glass stuck on the rudder which killed the water cooling and it wasnt far off siezing up.
anyway Simon as Kurt would say keep that pretty boat pretty ;D see you later...........Pete
-
That will teach you to drink and drive ;D ;)
-
me and Al got some really good footage of my makara and Al's razor today but i cant put em on they are far to big and it's only two mins of a vid ive done all sorts with them to no avail so im giving up, other sites ive been on let you put 100mb on..........Pete
-
Pete,
Put it on another site and give us a hyperlink.
Simon O0
-
stick it on u tube pete and link it to here,lets have a look at what you filmed mate O0
-
there still to big to put on you tube, both over 100mb............Pete
-
eureka i think ive done it O0........try this link
http://www.youtube.com/watch?v=xV181AXskKs
-
looks good pete once you get it trimmed to stop her hopping she will be pretty quick O0.did she flip at the end i couldnt quite make it out? :)
-
wheres the other vid??????
-
well where do you think it is this is a makara thread ;D
its on ac razor take 2 Kurt ok?
ps comments on mine would be usefull..........cheers.........Pete
-
? ::)flip ? ::)
-
I never know how to work out how these petrol boats are going?? It LOOKS pretty quick but SOUNDS like the engine is not working!
If it was a glow, I'd prop down a couple of sizes and bring the pipe in A LOT! But, as I say, I don't know sparkies.
The video is good. With a lake that small, you should be having to throttle down WELL before the turn ;D
Did I hear "Circuit Racing' mentioned in the background :( :P ::)
Thats the kind of handling you'll need at Windermere - just don't throw a left followed by a sharp right :o :o ;D ;D ;)
Danny
-
hi danny.he's running a 27 sikk in that boat,the engine doesnt work hard as it pulls a bigger prop with the power that it pushs out,not all engines need to rev there nuts off to get anywhere.the boat is fast and should do him well if he trims it up abit better ,theres still a little bit if work to be done,but the boat is good,and i know pete will get there in the end,,,,,,,,,, O0 kurt
-
Cheers Kurt - I bow to your experience O0 O0
When I started sparkies were as reliable as a Ford Anglia on a wet morning (ask your Dad??) ;D ;D ;D ;D
Danny
-
no mart it didnt flip i went to fast into the corner and it spun out and prop stalled
-
PS Pete - try it with the left hand fin (port) off or out of the water, - see if it still spins (clockwise turns ONLY) O0
Danny
-
did you mean my makara Danny? or Al's razor...............Pete
-
If you've a pony tail - it was yours ;D
However - after watching it again - ignore the last bumph about the fins :o :o Its turning well enough!
Just don't try to turn quick left then right O0 ;D ;D
Danny
-
yeah im the one with the pony tail Danny and it does turn quick but that last turn i went in at full bore i was just seeing what she was capable of.............Pete
-
When you gonna sort out the hopping? seems like your losing some speed there ;)have you tried adjusting the strut and balance etc.Simons doesnt seem to hop and i dont believe he has trim tabs so im sure you can sort it.I actually like the sound of the sikk motor how do they compare to a modded zen acceleration wise ? seeing as they run big props lower rpm are they a little slower out of the turn? maybe that could also be the reason for spinning out in the turn?ie the big prop.I would think a higher revving motor would corner better and accelerate faster.Im not knocking sikk either just a genuine question about them.
-
I think my C of G is further forward and i add up to two kilos of weight when its windy or rough?
Regards
Simon
-
I think my C of G is further forward and i add up to two kilos of weight when its windy or rough?
Regards
Simon
2 kilos :o ,out of interest Simon wheres your c of g ?.
-
we run the extra wieght when its really rough to keep the boat on the water at speed and not lift out when the wind gets under it,remember mart,we race no matter what ;D O0
-
Mart,
Just measured it its about 30% forward from the transom, petrol tank is mounted aft of the engine. From the stern:
Radio Box, Fuel tank, Engine, Added weight?, Bulkhead, old nitro fuel containers (for buoyancy)
Hope this helps.
And remember NO trim tabs on mine.
Regards
Simon
-
so if you had the balance point at 25% the front of the boat would be less flighty to start with am i right?.
-
no mart.the more forward the engine the more in the water she will sit,the further back the more out of the water O0
-
Mart, Kurt is right weight back puts the bow in the air, weight forward puts the bow in the waves!
The fuel tank is also behind, as the weight of a litre of fuel burns off it can make the boat flighty if forward of the C of G.
My set up gives stability at all weights but she sits up more as the fuel lightens.
I add weight to the front of the V at water line when things get rough to keep the bow down. Not too much though. If she wave jumps don't want all the weight at the front. Otherwise we have a 40 mph torpedo and end of race!
SO are you coming racing?????
Simon
;D

my makara today but still needs some work doing............Pete

my makara today but still needs some work doing............Pete
http://www.youtube.com/watch?v=FP2dPD8Wflo
Thats more like it mate ,sounded like the engine was deff revving better did you change the prop? or raise the drive line ?.
-
yep 275 prop but still not fast enough............Pete
-
no mart.the more forward the engine the more in the water she will sit,the further back the more out of the water O0
oops yup that makes more sense dunno what i was thinking lol ::).anyway mines at 30% ,ill keep some weight handy in case its windy when i run her the first time which should be a cpl of weeks time O0.
-
yep 275 prop but still not fast enough............Pete
Haha and after all you guys said about the sikk swinging a big prop the old dependable 275 comes to the rescue O0.Looks good mate a bit more adjustment on the drive and she will be there id say O0.might wanna try a 3 blade prop too 6717/3 or 6718/3 from propshop is what i was advised for a full modded 230 engine im getting soon .what sort of rpm does the sikk put out? the 230 im getting puts out 17,000 plus.maybe kurt has a cpl you could try ;).
-
ive just took a 3 blade off it a 270/3 im sticking to a 275 i think. i had some good advice from a few people today including Dave and Kurt so ill ajust it a bit more and test it at queens park tommorow............Pete
-
never heard of that prop but the propshop ones are suposed to be great just thought your prop guru might have one you could try ;).goo luck with it ,but get some paint on that hull O0.
-
my mate has a paint shop and he owes me one or three so when i get it all set up properly its being done yellow with a dewalt theme and my other mate is a signwriter and he owes me one too so the stickers are coming off him ;D it should look good with the three men painted up and mounted on the hatch.............Pete
-
cool im trying to think up a scheme for my new hull to go on the orange, my mate in the states will make me the decals again ill pay for materials and shipping again so a cpl of quid will sort that O0 err sorry dollars ;D.ps i dont think Als talking to me ::) ,by the way if weathers crap next weekend i wont be making the trip but i wish you luck the boat should go well,but be warned that lake gets very rough when the winds blowing ;).
-
me and the boat are not ready to race......... 1....... im not practised enough to race........2.........the boat is not ready.......... 3.........i would NOT like to hit another boat with my inability to drive in a race so when i feel im ready i WILL race and that is a cert...........Pete
-
Pete
"yep 275 prop but still not fast enough"
There's no such thing as "FAST ENOUGH" ;D ;D ;D ;D
Danny
-
mart,we didnt have time to really set petes boat up yesturday.as i was setting up my new boat which is running fast,as for swinging a big prop mate,i run a 482 prop on my apachee.thats 82 mm wide mate,they dont come much bigger than that.and my apachee is no slowboat,we do have to richen the engine up to pull that size prop.but pull it it will.try that size prop on a zen mate??? >:( >:( my mate runs a quickdraw and it WONT pull it.we put the 275 on petes boat without doing anything else just to see how it will run.but next time we are at the lake we will run a 482 and set the engine up to run it and video it.or i will video my apachee with it on,just to prove a small point to you. O0 O0
-
i wasnt having a dig i was trying to suggest a better prop im sure it will go better with a smaller prop versus a big one lol as it showed in the last video,now your on about fattening the mix?.i wasnt having a go whatsoever as for a zen spinning a 280 prop, no problem just fatten up the mix on the carb and she will spin it.not saying it will spin it as good as the sikk as i wouldnt know but it will def spin it.i run a 280 on my weedy,im sure a zen will spin it if that will,carb just needs fattening up to use the lower powerband of the motor.isnt that what your intending to do to his carb to make it spin the 482 prop? which is also the prop of choice for a weedy engine according to mr marles ;).
-
by the way no need to be so touchy mate no harm meant ;),but can you explain why if petes engine needed the smaller prop to let the engine rev you are now intending to stick a big prop back on and richen the mix? surely that defeats the objective of running a modded motor?.it was obvious from the second video it likes the smaller prop so if it were mine id stick with it and rather than go bigger id try the 3 blade props i mentioned,but thats just my honest opinion.you have more experience than me but thats what i would do ;).
-
By the way Kurt i posted a cpl of your vids on rcu to show a mate whos thinking of trying a sikk in his next hull.i told him to get the 27 rather than the 25 as they do seem to be running well O0.Who knows my next motor might be a sikk :o ;D.
-
well at long last shes running ok and quite fast so i painted her and here she is.
-
Looking good Pete
Will we see you in the winter series?
BW
Simon
-
yeah im hoping so Simon.
Pete
-
Nice shade of ORANGE mate O0 {-).
-
My mate and pit man has just taken delivery of his Makara, bright orange with a Z drive. ASBO racing team.
Being built as we speak.
Should be a few running next year! Cant wait.
-
whats with all these old makaras? id have thought a newer design would be more suited? not saying they arent great boats but they dont seem the fastest boats for racing?(old design) surely the sigma is the one to get if you wanna win?.
-
oh yes they are fast and they can take the rough because they are a BIG boat and why change something that runs that well.
Pete
-
They are big and can take rough water but they arent as fast as a propper race boat like the sigma ? there are many faster hulls out there than the appache hulls as like you say they are big and also heavy .Thats why i wondered why people are buying them to race ?they arent cheap so that cant be the reason.You say they are fast but lets face it they will never be as fast as the sigma .Dont take it the wrong way but i just dont get why if you wanna race you would buy an old design instead of a newer faster one?,just wondering.Im not into racing but seeing as you guys are surely you should be trying to win so buying a fast boat would be a good idea?.The last time one won anything was in 1999 if the nimriff site is up to date?,how much do they cost now? the sigma is £295 just wondered how they compare price wise ? as there seems a big diff in performance .
-
HERES ANOTHER OF THOSE GREAT MAKARA'S,ALONG WITH THE TOP AC RAZOR 45
-
Not a proper race boat?
Mart you disappoint me. :'(
What do you think an Apache is? :P
When was the last time you saw a Sigma racing in the world series? I know boats have come along way recently but a deep V still has the best sea keeping characteristics offshore.
Its not always about speed? The Makara is much better suited to rough conditions and can maintain higher speeds in rough water. If you mean its not as fast as the Sigma on a lake, i agree. But the Sigma is not as fast as a multi boat either. OMRA was historically offshore so the Makara was ideal.
The Makara from Nimrif is £120 and other Apache hulls are similarly priced. Its a cheap way to get racing. looking and talking to people about the 2008 OMRA series there are quite a few people who will be running Makara's. Kurt's Apache has been a solid boat for years and with the SIKK engine goes very well.
This was my first year racing and i finished a respectable 5th in the series with a boat from the 80's and being fairly inexperienced with race boat prep, tuning and running in a crowd.I will be running my Makara again next year and in the winter series.
Horses for courses.
BW
Simon
;) O0
-
Simon sorry to dissapoint you but put it this way which boat won the series? and with races to spare you say horses for courses but the sigma proved its worth and its ability in all conditions,who won at windermere? ;).I disagree the sigma not been as fast as the multi boat either,dave marles sigma is hitting over 60 mph so its plenty fast,you wont see many apache makara type boats hitting that speed if any.I wasnt meaning to offend anyone but i just dont see the apache or makara whatever you wanna call it as a race boat sure its stable but its not as fast as a lot of boats out there.Its big and its heavy two things against it,its design is also old school.You dont see many been raced in the states and they are generally considerred a sports boat ,dont get me wrong i love them both in looks and how they run but surely the sigmas of this world are the way forward?,there are others too which i would think faster and yet still stable.By the way sorry if i upset anyone im just currious why so many seem to still be buying these old boats instead of newer proven designs.
-
was there any big changes at the AGM Sunday? O0 O0 O0
more so on the free- board argument? >:(
hope it did not get too out of hand :police:
-
id back my makara against yours anyday Mart just say when and ill be there lol lol lol
Pete
-
Well not been a racer and this been my first zen powered boat you probably should beat mine but that said id say this hull should be faster than the makara once setup right it is after all a stepped mono.You seem to have a problem believing that the makara is not as fast as modern hulls well thats up to you mate ,i think the sigma hull proved its reliability and pedigree .I for one wouldnt be wasting my time buying a 20 yr old hull if i was going to race it doesnt make sense to me.Also seems clear that the omra guys are trying to keep the sport in the past by trying to ban the sigma simply because the older boats just cannot compete with it so i rest my case.
-
ive actually seen a makara do over 60mph and that aint slow.
Pete
-
ive actually seen a makara do over 60mph and that aint slow.
Pete
Yea but that was in the car on the way to the lake {-).
-
Ok lads nice and friendly no spitting out of the dummies!!!!!!!!!!!
Stavros
-
Oh yes! I'm building a Makara for next years OMRA racing. Should be a got year with so many closely matched boats.
-
Welcome to the forum Bill.
Hows the build coming along?
Simon
-
Good eve. Not bad. Done most of the painting jobs now. Starting to fit out the radio and link rods.
-
So post some pictures for all to see
-
Would do, but I have to confess I cant get the pics down in size. Anyway they are what i sent you last week. If you can downsize them then post one. Ta very much. ::)
-
Bills Makara so far
-
Well Done Simon. I knew you could do it with my pics.
PS. As many OMRA people would have known Syd From Stevenage model boat club and long time OMRA member. The Sad news is after a long struggle with ill health passed away last Tuesday. Very Sad.
-
welcome to the M.M.M. (MAD MAKARA MEN) Bill. i love mine and its a real head turner and its no slouch either.
yours is looking great so far and i love the barbies {-) O0
i can reduce pics too so if Simon's not around ill do it for you np.
ive just revamped the radio box and on the steering ive now got a hitec HS-805BB which gives a monster 24.7kg of torque at 6v.
Pete
-
Hi Pete
Thanks very much for your offer to down size my pic's. Glad you like my drivers. Poor bloke has got 2 women to order him around! till sould cause some amusement at the the OMRA meets.
-
welcome to the M.M.M. (MAD MAKARA MEN) Bill. i love mine and its a real head turner and its no slouch either.
Pete
Have you had it painted then Pete?,have to admit i like the Apache really call me old fashioned lol {-).
-
HI GUYS HERES A FEW BETTER PICS OF MY GREAT MAKARA,....YOURS MAD MAKARA AL {-) {-) {-)
-
There's certainly some very attractive boats being built by you blokes.
I think Simon might have a bit of competition for the 'concours' next year.
Now - the skill bit is keeping them looking like that ::) {-)
(not like my poor bruised looking ones)
Keep up the good work
Danny
-
Just One word!
Bring it on!
Oh thats three, shucks.
Beautiful boat look forward to rubbing, oops i meant racing with you.
Slipped again
Simon
-
You KNOW you'd NEVER let another boat even CLOSE to yours Simon {-) {-)
That's the only reason you've made it fast - to run away ::) {-) {-)
If your cat is in any of the classes I run in - well, I'll just apologise now :D :D
Danny
-
IT WILL NEED ANOTHER ENGINE THEN I BELEAVE FROM KURT YOUR THINKING OF A SIKK SIMON....AL
-
Thats because it spent most of its time sat on the bank on its stand.
Its nice cos it hasn't run a full race for such along time now!
The cat should be in AA when i can beg, borrow or steal an engine.
So wheres my trophy's then? Wife wants them on the mantlepiece
-
Your trophIES ('Concours' and 'OMRA Newcomer of the Year' will still be with Alan. You might have to pick them up - how far are you from Wickford?
I have a nice CMB 21 LS which I would be willing to swap (with appropriate adjustment) for, say, a used Zenoah (if someone were thinking about a change to er, maybe a Sikk) ;)
Danny
-
Pete,
I thought you had a SIKK?
-
looking forward to fleetwood sunday pete give all four boats a good run .....
-
Think i will play with the Zen abit more befor a new engine.
Really not sure what to go for.
Any ideas?
Simon
-
pete has a sikk i thought you was looking out for one soon simon to put in your red bull
-
I am thinking about it but the zen has been kind to me, thought i would tune it a bit and see what more she will give.
Have ythought of other engines.
Sikk
Pip
etc
dont really know whats best
-
Think i will play with the Zen abit more befor a new engine.
Really not sure what to go for.
Any ideas?
Simon
well simon i have had a couple of zens in the past and i have now got 2 sikk 27s one in the razor and one in the makara, and i love them,i have changed the pull starts which are a weakness on them,i use the zen pull start with the ally pawl in it,superb, the sikk in the makara is modded,and the one in the razor is standard,and gives kurts a run for its money,you wont go far wrong with a sikk 27....alan
-
i will have to see how your goes and make a decision, the zen is still in its first year so maybe some more power available?
-
yes you can try lightening the piston and a spot of porting,but i thing with All zen tunes i think you end up spinning a smaller prop, where as the 27 will spin a big prop and produces more torque,the prop on the razor is a monsterous abc chop prop and its spun with ease...al
-
hi simon when me and Al go out next time we will take some vids and then you can decide ;D
Pete
-
looking forward to fleetwood sunday pete give all four boats a good run .....
Hope you are going to behave yourselves on Sunday on my water?,pitty i wont be there shes got me roped into going xmas shopping.might swing by and have a look see if we have time what time you going?. Whats happened to your new lake i thought you ran at trafford park,by the way watch out for the duck feeding brigade ::).Unfortunately i wont be able to bring the boat im in the middle of redoing the radio box and installing new gear :'(.
-
By the way guys these sikk 27 motors just how good are they compaired to the zen ? the zen is very reliable so far just wondered how they compare?.I have no complaints with the zen so far but i do like the sikk 27 and im planning on building a big boat next year,maybe a cat not sure yet.From what you say about the sikk power wise it might be a better option for a big boat,allready have a sharp prather 280 prop for it.By the way what speed are you getting from the makara with the sikk motor is yours stock or modded Pete?.I need to get a speedo installed on mine and ill try and get a reading once im happy shes running to her max which she isnt yet, i think ill need to do a bit more tinkering yet ,plus im still not convinced this wrap forward header is allowing me to tune the pipe 100% despite what the hanson site reckons..

well mart bikers do behave sometimes untill someone rattlles their cage, >>:-( and we are bikers as well as boaters, O0 plus we do follow the rules, :police: untill someone tries to make the rules up as they go along, >:( {- so we will try and avoid any trouble at your water, oh and just as a matter of interest how much did you pay for this water of yours ??? {-) {-) {-)
for trafford we just pay a nominal sum and it belongs to the local council and we go there and enjoy.
Pete
-
i didnt pay a penny i just staked my claim lmao {-),therese plenty of the rule makers there ill tell you that now ::).by the way you never answered my question? anyway how fast is that makara going have you had it gps,d yet.simons looks to be about 40 mph ish maybe more so youres must be faster been modded?.
-
mine makes me shake and i can tell you this it's fast so come to your water on sunday and you tell me
how fast it's going.
by the way im just going to offer up my new radio box and get the pushrods done tonight+im meeting Al on queens park tomorrow with it so there is no excuse for you not to be at fleetwood sunday and im at work tomorrow 8) O0
Pete
-
how do you carry the boats on your bikes? or are these bikes only a distant memory? {-).,by the way just been told she has to work sunday so looks like i wont be able to make it so dont forget that video and a gps reading ;).

hi bill thats mine ...and yes it should they are a good hull, what are you putting in it....alan O0

Hello, Zen 26. I may get it tuned up but going to sart with it as standard.
-
HI BILL I HAVE TRIED A COUPLE OF ZENS IN THE PAST AND HAVE NOW SETTLED WITH THE SIKK 27 A GREAT LITTLE ENGINE O0...AL
-
Hi Al
Got the Zen with low hours on it from another boat. I want to do my 1st full year with the Zen then I do intend to move on to a Sikk. + I need to get some more pennys in. May be I will move on up sooner thn later. Have a good weekend boating. Im down the lake Sunday ,lets hope it's not to cold. :)
-
My Zen has run its first year ok, it does lack that punch when you want to get past someone though.
Do the Sikk engines mount the same as the Zens?
Simon
-
simon you can buy a lightened piston for the zen that will help things also you can do some port work or get it done for you.from what ive read and been told by a mate whos had both motors the zen is by far the more reliable motor,but you will probably know that? .spares are more easy to buy too id say.put it this way all the records for gas boats are held by zenoah motors,there is a reason for that you know.shes not let you down yet so id say stick with it.if you need more punch get it modded O0.that said you can buy a modded zen from bonzi and they only charge an extra $50 for a mild mod.or how about this one,not a bad price at all O0

HI SIMON YES THEY MOUNT THE SAME SPACINGS MY BE A LITTLE DIFFERENT BUT THEY BOLT TOO 5" RAILS AND ARE RUBBER MOUNTED.... O0...AL
-
I was worried you might say that!
Looks like if i want to be competative i will have to lay out for a SIKK and join the oneil bros club.
Just wanted to be different!
-
Sorry Mart, missed your post, where are the hops ups available on the zen.

My Zen has run its first year ok, it does lack that punch when you want to get past someone though.
Do the Sikk engines mount the same as the Zens?

hi mate heres the full list i think if you search the site you may find some parts to do your own mods but not sure havent looked on here.that said im sure you could sell your zen and buy one of these with some of the cash they are so cheap .you canm also send them your motor an they will mod it for $150 for a race mod and $350 for a ultra mod which gives it 5.5 hp.

this ones a race mod 5.2 hp for $150,unless you know someone who can mod it for you?.

SIMON I HAVE BOUGHT FROM BONZI AND SO HAS PETE AND WE HAD NOTHING BUT TROUBLE, ASK KURT HE WILL CONFIRM THAT, THEY ARE THE LAST PEOPLE YOU EVER WANT TO DEAL WITH,AS FOR PARTS YOU ONLY NEED A CARB 257 WHICH YOU WILL HAVE,AND A DREMEL,SO ITS UP TO YOU NOW MATE I CANT FORCE YOU BUT I KNOW FROM MY OWN MISTAKES WHICH IS THE BETTER ENGINE AND THATS THE SIKK,I RUN 2 OF THEM ON IN THE RAZOR WHICH GIVE THE PATRIOT A RUN FOR ITS MONEY AND 1 IN THE MAKARA....AL

Not keen on buying from the States due to the import tax, the strength of the pound does entice you though.
Mum and dad have a house in Florida so i can have stuff shipped there but they wont be over there until next year.
I have a new boat on order for next year so might be woth leaving the current as a spare and running a new set up?
Depends if i can get away with it with the boss!
-
Bonzi are great to deal with ive dealt with them several times never a problem ,my mates just got two new motors from them both modded no problems at all.Heres the one id get simon a great price too.Alan you havent had your sikk for a year yet have you? lets see if you still say the same things about it when you have raced it for a year as simon has the zen.I do agree though that its not hard to mod the zen if you know what to do.

by the way simon import tax on the zen is exactly £29
anyway why not go the full hog and get daves zen 7 at £335 for 7.3 hp

Can i not just but a lighter piston, different carb for the Zen and do some porting myself?

Has anyone seen Dec07 Model boats mag. I seem to have got into the photos not once but 4 times. Lucky me??/ ;) It's the write up on Windy. Seems you run an "Apache" accordding to the report Simon. :D
-
Hi Bill,
Got it this morning, make the most of your 15 minutes of fame!
Not read it yet. V tired, up half the night trying to get this new computer working and everything swapped over.
Hate the things!
Hows yours coming along?
-
Hello Simon. It's coming along. Hope to be doing some trails soon. 3/4 weeks me thinks.
-
Will you bve having ago up at Willen in the winter series?
-
No Can't do Willen as 2 out of 3 dates clash with other things. It's a pitty but there you go. Looks like I will be able to do most of the OMRA meets next year.
Off out to dinner in a bit. Have a good weekend. Cheers Bill.
-
Alan,
None taken, catch up next year!
BW
Simon
-
hi simon i was caught up in that one too and lifes to short to argue, so my aim is to meet you in a race sometime with Al and have a good time, thats what its all about.
sorry to mess up your thread and i hope that doesnt ruin our trust with each other.
cheers...........Pete
-
Pete,
No worries, this is supposed to be for pleasure. I know how easy it is to get sucked in.
So you did not end up with the yellow paint job then? As far as two pack is concerned you can still get it and use it.
My new boats are going to be two pack, pearl. Then the decals and then lacquered over the top.
Another Makara we are building is going to be ST Orange with white rally stripes. White base, orange, pearl mist and then lots of lacquer. Runs with a Z drive. I tried to talk him into 2 Zen 23s and 2 Z drives as per the full size.
Looks like there will be a fair few of the Makara's racing next year. I will also see how i get on with an AA
Have you seen the full size Apache videos on UTube?
BW
Simon
-
hi simon i did paint it but did it myself with spray cans in yellow here's a couple of pics of mine and Al's makara's plus the sign i hit and bent with mine when i could'nt see the boat for the sun :embarrassed: {-)
Pete
-
is this the full size one you mentioned earlier simon?
its absolutely awesome O0
http://www.youtube.com/watch?v=iHr4LbyL2W0
Pete
-
One of them, absolutely awesome.
I want one that sounds like that!
What do you think of twin Z drives on a model one?
Simon
-
yes pete you and those post you just cant stop hitting them :embarrassed: i think you should play footy for england, he he he {-)...you was very lucky not to open the hull up, and dont forget you ruined my afternoon, {-)....al
-
One of them, absolutely awesome.
I want one that sounds like that!
What do you think of twin Z drives on a model one?
Simon
hi simon i love z drives they look the biz and are great on boats for pleasure you do lose through them,but for racing you cant beat direct drive,i would like twins in a cat i am thinking of doing, but will end up putting a single 27 sikk in it due to funds....al O0
-
Not a lover of Z drives on full size boats. Had one with a 350 V8. Searay Sundancer 270. Very unreliable and the engine has to come out if you want to replace the seals or work on the back end of the leg. Direct drive is best, twin is evem better!
-
i didn't realize you where talking real boats I'm on about models,...al
-
Sorry for the confusion, dont like them on full size, think they look the part on models as they are an accuate of the original 80's boats.
Thought two Z's with 2 engines in a Makara would be kinda fun?
Simon
-
anyway Al how did i ruin your afternoon. :(
it was us that ruined the old ladies afternoon or so she said to you {-)
Pete
-
only joking thats what i was hinting at,its you that attracts them look at the last one bricking your last one,the makaras are within the allowed db range you always get one.,do you have any trouble Simon with the locals your way.....AL
-
yeah yeah yeah you mean the bag lady {-) {-) {-)
that was funny.
Pete
-
Not really, we run at Brentwood. Its a private lake off the beaten track and next to the A12. A bit Small for C and D boats buts its the only place around that is fresh water
-
thats good the one in the small vid and pics we use is in a public park, and the old lady the other day was the first really to complain, we only use it for testing as that is small also, only big enough for one boat at once...al
-
Hi All
Hope you don't mind me jumping into the thread but it makes very interesting reading.
My son and I are about to embark on a makara build [stock Zen 26] with the plan to run it in next year's OMRA series for a bit of fun. It's our first build so I dare say I'll be on the cadge for as much help and advice as I can get!
No pix yet as the hull should hopefully arrive tomorrow with a load of parts so we can get the thing built over the Xmas hols.
I've spent the last month or two planning and sourcing parts and stuff and designing the paint scheme which hopefully will give Simon a bit of a run for his money! ;D
Anyway, as soon as I get cracking on it I'll start a thread and post some pix.
Cheers
Phil

Welcome to our builds Phil.
Good to have you on board. Excuse the pun!
If the hulls coming from Paul, don't hold your breath!
Looks like there will be quite a few of us next year, and a fair few very pretty new Makara's. Paul will be happy!
D definitely seems to be the fastest growing class. At this rate we will need 3 heats or even a break out series of our own. Now theres a suggestion.
I have a rebuild over the winter myself, just ask if you need help. The buoys are very helpfull.
It will be good to see them all racing together!
BW
Simon
-
Simon
3 heats in a day , that will one hell of a wait for a race !!! i think your idea of splitting d off is fantastic and how about running " d " up to 25cc and having " e " class as 25 and over
and how about proper races of 1 hour and even 4 hour endurance and night racing !!!
OK i"ll stop there , just interested in more racing !!!!!!!!!
tony
-
Eve big fella
Dont stop there. Tony for chairman.
I agree with all of the above, how do we move it forward
-
could we get a UK team together to go over to France and race in the 12 hour team race !!!!!!!!!!! ( its even on sky TV !!! )
what do you think !!!!!!
tony
-
Put me down! O0
-
Having D class racing on ther own is a bril idear. :) Would that mean longer time on the water? I am with the rest it's a long time to wait till the end of the day to race. YES go for D class meeting on our own. 8)
-
Mines coming along.

Inside my boat.
-
Looking good Bill, have you run her yet?
Have you got a bulkhead?
BW
Simon
-
Hi Simon.
Yes it's going well . I have lots of small jobs to finish. Maybe i will get some done on Saturday, if Her indoors dose not want me to do the Christmas shopping.
I am trying not to put a bulk in as I may well fit a ballasts tank + pump in the front. I have got loads of foam float stuff to fit in. That should keep her from going under.
As and when she dose take to the water I will see if I can get a video of the event. {-) O0
-
hi bill it's looking nice hoping to see the maiden soon lol.
Pete
-
Well that day has come when weeks of work have been placed in that big lake. Pity about the rain but it did little to dampen my spirits. The engine was started after a little pulling on the starter rope, dumped in the water and off see went . Not bad I was thinking, When this woman who must have got out of bed the wrong side started to rant a rave about the smell, up setting the wildlife. In Stevenage i took it be all the local youth but they was all in bed. No she meant the Ducks!! Sill Blow it all I was having a lot of fun. A few things to short out, but things are looking real good for next years OMRA racing. Cheers for now Bill.

Ducks being disturbed, funny the one in the video deos not seem that bothered
Stavros
-
its running quite well for its first run.
on my first run i opened her up, and it lept out of the water on its prop and could not keep the front down and it took weeks to set up even Kurt was baffled by it.
on further inspection there were two large rockers near the transom, so i got the heat gun out and put trim tabs on.
now it will not turn left.
Pete
-
Hi Pete. Yes Very happy apart from a transmiter full of water. Still it's now drying out on my rad indoors. ::) I will have to reset it all agian. Oh well all the fun of boating in the rain 8)
-
Hi Bil yes good maiden run,mine to like Pete's had rockers in the hull but removed them in the build now with adjusted trim tabs runs well at turns well both ways,i look forword to seeing you at the odd race next year...al O0
-
AL
Talk to me about these rockers?
Simon
-
Simon
"Rockers" are big hairy bikers from the 60's. If they had a couple on the back of the boat - it's no wonder it didn't go {-) {-)
Hope they removed them politely!
Danny :D

Thanks Danny, can allways rely on you top look at things from a totally different angle!
Hows that Magnum coming along. Want me to fit it out for you, and add the paint?

Hmm,
I had until very recently a Panther that would not turn left. I mean, full left rudder and nothing happened at all. As soon as you shut the throttle it would turn, but not until then.
I cured it eventually, at least it seems like I have. If I get some flat water in the next week or so I will try it flat out and see what happens, but so far 100% better.
Those Makara's seem to go well.
Glenn

Glenn,
I had a similar problem racing at Bristol this year. It turned out to be the servo, i changed it and it was fixed?
Regards
-
Mine was a trimming issue. Took half an hour to sort, just needed the drive moved over. And a rudder adjustment.
Glenn
-
ive just put a hitec hs-805bb 25kg of torque at 6v on the rudder and that was the last run and still no left.
hence the bent sign :embarrassed:
Pete
-
Maybe you got your rudder too far over to the right ? also try a longer rudder could also be prop walk ? is the prop sharp i know the last ones probably a no brainer but if its none of those things then your hull has a serious hook in it somewhere ?.As it seems more than one has this fault maybe you need to send it back to nimriff? .My mates cat was a complete disgrace from them and it went back for a refund (after solicitors got involved).Werent you singing the praises of this boat a week or so ago yet it wont turn left i find that strange,so its not quite as good as you reckoned then?.
-
What prop are you running? sounds like it could be a lifting prop which could be making it bow steer?.Also have you painted the hulls bottom? this can also alter things for the worse,also check your strut is dead stright with the keel line maybe its twisted slightly to the right ?.MY MONEY IS THAT BIG PROP TRY A SMALLER ONE AND ILL WAGER THE LEFT TURNS COME BACK ;).
-
Read this,lifting props if its octura has no letter on it you need one with a v or an x on it for a non lifting prop.Anyway read this lot and maybe you will find your problem.maybe your rudder is too short? mine was on my woody so i made a longer one?.

Well finally my Makara hull has arrived together with some of its bits and pieces, albeit I am going to have to hang fire on a lot of the work until I get the engine mounts which could be another week or two. [I don't want to start mucking about with the tube until I have got the engine in. Dunno if this is right but it strikes me that I need to get things lined up reasonably well, first time].
I had a good look at the hull and it seems to be ok [with the exception of a couple of gelcoat flaws in the topsides which a bit of judicious gelcoat filler should sort out. The hull itself seems to be free from any flaws going by eye but until I get a decent straight-edge on it, I won't be sure.
This is going to be my first build so Simon, stand by to be bombarded with seemingly stupid questions!
I'll do a full pictorial on it as the build progresses, [if that sort of thing goes down well here?]
Cheers
Phil
-
Hi Pill
Good to here your boat has come in at last. Re engine mounts. Are you fitting stringers? I did on mine using 9mm ply. It adds a little weight bur it all so strengthens up the hull. Re the gel coat. Snap. It would be interesting to know where yours are to compair the two boats. Who's running gear are you using? I used the gear that Paul suppled which seem's to be OK on it's first outting last week.
If I can be any help just sing out.
Bill Warder. O0 :-\
-
Hi Bill
I hadn't planned on fitting stringers. I was going down the route of glassing in the mount bases to the hull. Paul at Nimrif suggested this method was much more preferable to using ply stringers and on the basis that he has far more experience than me, I thought I'd take his advice!
Having said that, I'll give this method a go and if it doesn't perform as well as hoped then I may well look at a future build using stringers but perhaps made from a composite material. [No possibility whatsoever then of the stringers becoming soft through water ingress].
As for the gelcoat flaws, I have a few creases on the topdeck, port side. Nothing too serious and a bit of P40 should sort it. When it's been painted and lacquered, I don't think they will show at all.
-
Phil,
By the sounds of things there is a flaw in the mould, all the marks are in the same places, a mate of mine got his a couple of weeks ago and we have compared, pretty similar. His however has been rubbed through in a few places and gel filled afterwards. Its all going to be painted anyway so don't worry to much about it.
Paul does not like stringers!
I fitted as per his recommendations to begin with. OK for two races then all came apart. Took another 3 attempts to get them in and solid. Most of my early race problems were with that type of mount, both on the radio box and the engine.
For whats it worth i will always fit stringers. Weight is not a problem with this boat. I have to add weight in rough conditions and am thinking of adding more strength/weight/glass fiber in the rear anyway. Big dissadvantage is if you want to run a different engine, some are 5 inch and some 6 inch. Stringers add strength front to back and dissipate the loads of the engine. The feet cracked my outer gel coat where they flexed. Mine are 5mm marine ply, 2 inches high and glassed in all the way. With a solid glassed in bow bulkhead.
Always here to help.
BW
Simon
-
Sound advice if you ask me Simon! Thanks!
I had a feeling that those flaws must be in the mould and like you say, they are going to get filled and painted anyway so I am not going to lose any sleep over it.
As for the stringers, I had my own thoughts about going down the route of mounting directly to the hull and was a bit twitchy about it, so I think I will go down the stringer route. Did you beef up your transom incidentally?
Had you thought about using anything other than ply for the stringers? [I know Paul doesn't like 'em as he suggests that they can get soft after a season or two of getting damp, hence the thought of using a more modern material such as some kind of composite or plastic for example.] Certain types of acrylic sheeting are fuel resistant and a 5mm thickness should provide more than adequate strength I would have thought. I was curious as to whether anyone had ever tried it before as it would seems to address the drawbacks Paul seems to suggest are prevalent in wooden stringers.
Any thoughts?
Phil
-
hi phil
been using carbon stringers for a long time now with no problems , as simon says added weight is not a problem and the added advantage of the stiffness with the stringers will ne a real help , also beaf up the transom area arround the rudder and strut mountings
here to help !!!! :)
tony
ps simon , its done !!!!, just got to put it back together for you O0
-
Hi Tony
Thanks for that. I guessed that someone out there was already doing something along those lines. Next question then Tony, is how expensive is carbon as a material to buy in a form that lends itself into making stringers? I have been mooching around the www and I can find plenty of places that will flog me carbon sheet, but they all seem to want to divest me of a limb or two in the process.
Can you tell us how you go about it?
All the best
Phil
-
Phil,
I did not beef up the transom, not that much hanging off it. When i built it originally i went for a strut. I have now changed to a stinger. Our other one has been beefed up with 5mm ply, that will have a z drive hanging off it though!
I would think that if the wood is sealed properly it should be ok. Marine ply does last, probably longer that the boat will the way we run.
I like the 5mm plastic idea, best of both worlds, do you really need the carbon?
BW
Simon
-
Hi Simon
As you say, going by the way the boats are run, it's probably a bit moot as to whether to worry about the stringers going soft! I am not convinced about whether my idea for using acrylic would work - I may have to do some testing but as this is going to be the first boat, of a couple [one for me and one for the lad], then I suppose this one can be a bit of a test bed. I might start some resistance tests to fuel on some acrylic this weekend though. Carbon is a great idea as it is light, strong, inert and easy to work with. I am not sure about the VFM though!
What made you switch from a strut to a stinger incidentally?
Cheers
Phil
-
Phil,
More adjustments, up down, in and out! Intersesting post by Martin on set up. Well worth reading. I have suffered with a bit of porposing when running on calm water on my own.
This was my first big petrol boat so it was suck it and see. I am sticking with the Makara next year but want to start tuning her. Where there is adjustment you can tweek.
She's running at about 39 mph and i want to get her up to the mid to high 40's. Dont think the hull will stand much more. Just need that bit of extra zip when passing.
At least thats what i am going to have a go at. I dont run a turn fin or trim tabs
Simon
-
phill
the carbon i lay up myself ,epoxy in the summer on a peice of glass .cut it up as i need it
simon your boat will do more than 50 in race trim now ;D but you are right about the hull not standing much more , the 35 in mine is a real hand full !!!!! ::)
-
T,
Keep it on the QT!
-
So Simon's been having a bit done on the side! :o :o
Scoop ...... are you listening! You should just about be able to let the cat out of the bag before the start of the season ;) {-)
Simon, the hard bit is when it's just a BIT faster than the one in front, and you have to go round the outside (as you know!)
So if it will now do 50, you're in for an easy life {-) {-) {-)
Phil, never use acrylic on anything in the boat (even the radio box lid) as it cracks at the first hint of vibration! It would certainly crack if used as an engine mount! The only stuff of that type you could use is Polycarbonate (Makralon) which will resist cracking but is an absolute bu**er to bond.
If you notice, almost none of the 'glow' boats have stringers because you need a much bigger tank than a petrol, which usually takes up the whole width of the boat. If your hull is standard polyester, the mounting post method possibly supplemented by an extra thickness of glass under the engine area, will last ages (or until you slam into your first buoy - a large lump of metal decelerating from 50 to nil in less than a foot ......... ) ;)
If you go down the 'non wood' stringer route - carbon, on its own, is very brittle and subject to shear fractures. The best would be a 'sandwich' of carbon (for stiffness) and kevlar (for strength). You would have to use epoxy resin for layup and use the same resin to bond to the hull.
Good luck with the build.
Danny
(water's going to be FULL of Makara sparkies next year) ::) ::) {-)
-
Evening Danny,
Just fishing! Thought if i threw the right bait i would catch something. ;)
I reckon that there will 8/9 Makara's running next year! Pushing 3 heats in D at some events i suspect. Someone is doing quite well i think! O0
These old boats still look the part and will look good in a crowd.
BW
Simon {-)
-
Glad you liked the setup info i posted Simon ,by the way those hulls regularly run in the 50 mph range with the right setup .At least thats what the guys in the states are getting,my mate has an appache and his runs almost 60 thats with a fully modded engine done by one of the top guys in the states.He says its uncontrolable at that speed though so id say 50 is more than enough O0.By the way you can buy a propper appache for the same price as those makaras you know?,why buy a faulty one when you can buy an orriginal pluss the guys not nice to deal with either as you know.the cat my friend bought was horrific ,holes in it hooks ,twists you name it there wasnt a straight line anywhere on it.Its so obvious to me hes using faulty moulds ,several of you have the same faults on your boats? speaks for itself i think.
-
Phil,
More adjustments, up down, in and out! Intersesting post by Martin on set up. Well worth reading.
Been looking for that topic, but not sure which one you mean..... Any chance of a linky?
TVM Simon.
Danny, thanks for the advice. I am still in 2 minds as to which route to go down with the engine mounting method. The Makara hull needs beefing up either way imho, as there is loads of flex in the undersides and a bit of extra stiffness wouldn't hurt. I don't think the extra bit of weight will make that much difference to overall performance to be honest either. So its either gonna be stringers, [which I have to say I am leaning towards at present] or a load of extra lay-up and glassed in posts, [which I am not overly confident at being able to pull off successfully].
In writing that, I think I just made a decision........ stringers it is! O0
Thanks for helping me to focus my mind!!!
Cheers
Phil

Phil go back to the last page i posted a link to some info on setup etc,makes interesting reading mate.By the way have you guys seen those Sg motor from Italy yet? one of those in an appache will hit 60 mph ive seen a few on another site.HERES A LINK TO THE SG SITE THERES A CPL OF VIDEOS OF BOATS RUNNING THEM TOO these things are awesome.if i find the vids of the sg powered appache ill post a link ive seen it somewhere.

........ or a load of extra lay-up and glassed in posts, [which I am not overly confident at being able to pull off successfully....
I used posts in the L ynx and stringers in my Sigma and have to say that I prefer using posts as you have more options as to where to mount everything else that goes into a boat. However both these hulls are epoxy layup and therefore more flexible allowing the hull to absorb the point loadings of posts without cracking or separating.
Polyester hulls, in particular the gelcoat, are stiffer and more likely to crack under point loading. Judicious use of larger patches of extra glass under the posts to spread the load could reduce the likelihood of hairline cracking and separation on these hulls.
-
Stick to stringers and just slot the holes for and aft with a dremmel that way you allways have adjustability to change your balance point if needed O0.The stringers will also add stiffnes to the big hull you have which i bet flexes like mad been poly?.Not sure what the price of the sg is to be honest but its probably arround the price of a full mod zen but maybe Ian can clarify that one?.I know one guy who runs in omra has an sg in one of his boats not sure if hes raced in omra with that one yet though,if hes arround maybe he can let you know how they run.You cant go wrong with a zen for reliability though and theres lots of mods you can do or have done if needed.Good luck with it ;).

Cummon Ian i was only about a $1000 out lol :D
-
well i must say the makaras are coming out in force now ,it seems a very popular hull,and not something out of the ark as i once heard,as for the sg £1000 ,and it sits in 6 inch rails,don mauro, in the states runs one in his ac razor 45 and it was clocked at 75 mph,well i have some more money to burn so i am now building a 60" cat that actually measures 58" it will be run with sikk power of course, will start the thread with pictures soon....i think a makara club is long over due...AL O0
-
yeah a MAKARA club sounds good.
oh and by the way ive seen that cat of Al's and with the sikk in it that thing will purr {-) O0

DONT YOU MEAN THE WOODY EATING WILD CAT WILL ROARRRRR {-) {-) {-)

Well, [gulp] it's leap of faith time!!!
I'm just off to drill a big hole in the transom...... [stuffing tube]. First time I've done this and I'm keeping my fingers crossed that I don't s*d it up!
Here we go!
[/me goes off to the workshop clutching offset diagrams.....]

-
Makara Club. YES YES YES! How about our own D Class only OMRA Days!!!
-
well im not running my makara with that wild cat, mines only a bobcat makara and yours will look like its off boatbot wars with the circular saw in between the sponsons {-) {-) {-)
Pete
-
Well that went a hell of a lot easier than I expected!!!
The old adage of "measure twice, [or 5 or 6 times!] and cut once" was in full effect!
I was a bit twitchy about going too close to the underside of the hull and because the layup is so thin, I took a few precautions...... Once I'd marked out what I thought was the correct location on the outside of the hull with a marker, I just shone a torch on it and stuck my head inside the hatch to see if it was going to foul the hull. It was close but okay!
Enough mucking about on it for me tonite though I think. I've had some cr@ppy virus all week so I will leave the rest until tomorrow.

hi bill now your talking it would be a wonderful sight all the makaras on the water at once,quite evenly matched and just down to driver skill,...all mad makara men together {-) {-) we are i will see if it can be made to happen some time in the new year maybe at our fantaic water at trafford...al O0

Looked like you cracked it and with the pencil lines very accurate.
I just drilled it in the middle by sight!
Trafford is abit far for us Southerners, anywhere abit closer to the middle?

Quick tip - which you probably already do anyway - NEVER drill a hole in the hull the size you want! Always drill it smaller and then file it out. That way, if the hole is slightly out, you can correct while filing.
Bit late I know, as you look to have done OK with your outer - but worth a mention.
Danny

Ooooh! You never told me that when i was building mine Danny. No wonder theres so much water in the thing.
Kingsbury sounds ideal!

I'm SURE I told you that the radio box does NOT need an air vent!!
Oh - perhaps not {-) {-)
Kingsbury would be handy - I could come along and jeer throw rocks help out!

Thanks for the tip Danny. As it turns out, that's exactly what I did! Drilled it slightly undersized and then dremelled it out until it was a snug fit.

now that sounds like sport. wheres my gun
-
Simon you shouldnt drill it in the centre the prop should be offset by 1/8 to the right to overcome any prop walk didnt you read all that info ;).Also open up that hole in the transom make it a slot so you can get easy up and down movement and just use silicon to fix the tube at that point O0.
-
My thoughts exactly Martin O0
Slot the hole so you can adjust your strut as needed to trim the boat.
-
No prop walk on mine, and its in the middle!
I did read it but did not believe it, proof is in the running.
Running a strut now so have full adjustability
-

Ahh yes but thats asuming your hull has no rockers or hooks in it which apparently the makara does??.maybe these have acted as a trim tab and corrected it for you {-).Ive yet to hear of a mono that doesnt suffer prop walk ,you allways have to correct it somehow its the nature of the beast mate.This is why most people put the prop offset to the right it will also maybe overcome any no left turns which i see some have experienced.
-

Just a thought mate but if you have a strut and adjustability as you say then with no slot and no movement for your tube you will be in fact bending the tube? this cant be good ,id slot the hole for easy adjustment of the whole driveline so it will move up and down without any restriction,its funny you dont believe whats written there by some very knowledgable people though.Glad yours runs straight though but id say on the whole running the prop dead centre is going to create veering to the right in fact i know it will.
-
I meant to say bending the flex against the tube ::)i find it much better having movement in the tube,my first boat has a fixed tube ive since learnt through experience thats not the way to do it.Now i have all the up and down movement i will ever need and it moves with ease .Each to theire own and good luck with however you chose to do it ,just trying to save some people some work down the rd when they suffer from a boat that wont go straight as i have in the past .
-
Running a strut now so have full adjustability
So you have a slot in the transom.. otherwise all you can adjust is drive angle slightly and not prop depth...........
-
How much oversize should this slot be then gents?
Also, do you glass the tub in further up the hull, or just rely on a clamp close to the collet and silicon by the transom?
Any pix would be of much help.
Thankee!

I made my slot as big again so i can move the strut up to raise the prop out of the water when needed to let it rev out more.Yes silicone at the transom and a clamp near the collet is all is needed,either a shop bought one or you can glass a plywood homw made one into the hull as i did,i drilled through it installed two stainless bolts into it then glassed it in and bent some ali plate to shape and that is bolted down using nyloc nuts and thats all that holds the tube,this way should you ever need your tube out its just a case of removing the nuts and it will pull out .The silicone is strong enough to hold it in place but it will come apart when you need it to O0.

................MAD MAKARA {-) {-) :D :D AL
-
Mart,
The only reason mine would not turn left is because i put a smaller rudder servo in it and it was not man enough for the job.
When i put the bigger 1/4 scale back in it was fine.
Nothing to do with prop walk.
I think the general concensus is that Makara's don't suffer with it, something to be said for an old deep V boat!
O0
-
Al's turning left
http://uk.youtube.com/watch?v=cnsSAgc0RJU

I think that definately turned left?
Maybe though :-\ the camera converted it to a negative and mirrored it.
What do you reckon, shall we ask xxxx? {-)
-
hi Simon i took that vid on my phone and honest there was no jiggerypokery {-) {-) {-) O0
Pete
-
Looked like a left turn to me. Got my boat to go left now, not as sharp as that mind but certainly sufficient. Right turns are tight. Might try to incorporate unequel rudder throw into the linkage to give more on left turns. Not really an issue mind. The strut and rudder adjustments made a load of difference, really is like a new boat, and that is without trim tabs.
And no prop walk now either on mine!! :)
Glenn
-
hi glenn glad to here your sorted,a good servo in mine now that made the differance,and there not alot of money either, about £27 with post, doing about 24.7kg at 6 volt through a y lead...alan
-
That's a monster servo Alan!!
I'm using, with success, Futaba S3305 @ 9Kg/cm. (at 6volts) Working OK for me. It is also a fast servo, .2 sec for 60 degrees.
I think the rudder positioning and shape plays a part in how much servo power is needed to turn the boat.
I also am running this servo in an FSRV boat just now with success, I will try one in my next boat too to see what happens, but as that is a 90 sized FSRV I think it might be a step too far for this servo. Time will tell though.

If you are running digital sets, cant you increase the throw on the left hand rudder, say 120%?
I have to reduce mine to about 85% to stop it spinning out in the turns.
Not running trim tabs or a turn fin though.

Hi Alan,
I could set throw differentiation on my radio, but I use two transmitters for my boats so would rather do it through the linkages and more mechanical means. Then I can use either TX with ease. (Truth be known, I can not be bothered to program the TX's up!!)
Glenn
-
hi glenn i use a spektrum set one does all three boats,but it took me ages to be bothered to set it up properly,i used to have a differant set for each,but its lots easier now...al O0
-
I have a 6 channel futaba digital unit.
10 model memory
I have about 5 running on it at the moment, just switch and save.
Easy peasy
O0
-
I have the other problem, I use tow TX's for my models, so they all have programs in each TX.
The reason for this is that I have an FSRV boat with trim tabs all over the place in it which are linked to the rudder and only one of my TX's will do this for me, so I end up with the situation I have.
Glenn
-
yes Glenn i had the same problem but with th spectrum and its different model memory it eliminates that problem...AL

I've had a few S3305 servos. Right up to a CMB .90 powered Magnum. I also used one in a "B" (.67/11cc) class, and a couple of "A" (.45/7.5cc) boats, and didn't have any failures or servo problems with any of them. All of the above were submerged drive though, and all were stolen just over a year ago - so I don't know how they're working now !!
Ian
-
hi Ian sorry to hear about the boats going,as for the servos i cant really comment about the force on the rudder in submerged drive as to a surface drive i think the rudder area is smaller on the submerged drive so wont need as much power to turn it, i could be wrong,all i know is that mine and a lot of other peoples boats i know needs a high torque 1/4 or mega 1/4 scale servo to turn it especially left at high speed with the of set rudder....AL O0
-
Al, Ian is correct as you guessed, a submerged rudder is balanced ie there is usually about 30 - 40% of the total area in front of the shaft which counteracts the force on it also, as the whole rudder is constantly in the water, a smaller size gives the same effect as the long wedge rudders we use on surface drive.
Don't forget that, as well as having a strong servo, you also have to beef up the linkage, especially if it is long or there are any bends in it. Linkage flex causes more problems than a weak servo.
Danny
-
hi danny my linkage is 3mm stainless rod, from mark copley...al
-
Cheers Al - a warning to all to make sure your insurance covers your boats, and where you keep them. I had to fight my corner with my insurers, but probably recovered about what I originally spent in the end - so I acquired a new collection pretty quickly.
With regards to servos (and linkages), and turning left, I guess, in surface drive applications - depending where the rudder is in relation to the prop, to go left, the servo is fighting the prop wash to move the rudder. To go right, the propwash may help the rudder - aside from all the other factors.
Bill,
If it doesn't hurry up and warm up, I don't think anyone's gonna be running boats at Fairlands on Sunday.

Hi Ian. Me thinks we need an Ice breaker on Sunday. See you at the AGM. 10.30 am
-
Hi Bill
I note from the provisional OMRA calender that Stevenage have not said whether they are able to hold an OMRA race in 2008.
I hope that, with the sad passing of Sid McGown, that someone else takes up the challange of holding an event. Last year, Sid said that the local council were "word not allowed" about, with new rules that put the burden of 'policing' the whole lake onto the SMBC.
There was also some 'rumblings' about safety and racing events a few years ago, which (I believe) came from other sections within the club. There may have been 'hidden agendas' at work but, not being a member of the club, I cannot comment. I do know that - unlike Mayhem, some clubs have certain members who 'stir things up' and do not like anyone in the club catering for anything not directly for members (thats my polite way of putting it). These things have a habit of cropping up again and again at AGM's.
If you can host an OMRA meeting, I'm sure it would be well received and a fitting tribute to Sid's memory as he helped model boating for many, many years. Organisational and practical help would be freely given both before and on the day.
Have a peaceful AGM.
Danny
PS 4th and 18th May, and 22nd June appear to be still available. ;)

Hello Danny.
Yes Syd's passing away is very sad and i am sure he will be very much missed by many model boaters around the country. I had the pleasure of meeting only about two years ago when i got back into RC boats. During that time he showed me much encouragement.
We are having our AGM on Sunday this week. Syd was our chairman so we have to elect a new chairman. Once this is done the SMBC will be able to start shorting it self out.
As Syd pointed out at this years meeting at Stevenage the local council want so much from the club in the way of money and insurance it makes it almost impossible to run OMRA races.
However we can use or normal lake which has been used for OMRA races in 2006. I know Syd did want to hold a friendly meet on this lake. I would like to hold it in memory of Syd. I did suggest this at club level but I will bring it up again on Sunday. We have all the kit to do the job and many keen folks to set it up. Lets hope others see it my way on Sunday. Bill.
-
Still hoping for some wet stuff to have a run before the AGM (ever the optimist).
Syd will definitely be missed by many. As a face on the circuit, and at the club. His sense of humour, and the qualities Danny alluded to with the "expletive deleted" - although I guess that was all tied in with his sense of humour and attitude to life. I can't think who will replace him as chair of the club. I can only guess at who may or may not stand.
We had a couple of OMRA races on the small lake, and yes, some concerns were expressed, but having done a risk assessment, and addressed the main weak point, we as a club felt (and I still feel) that it's as safe as most venues on the circuit, and safer than some. I thought the concerns had come from one or two within OMRA, but I could be wrong. It's definitely small, but I think most managed to enjoy the races held there, and most adapted their driving to the conditions.
I'll be right with Bill on the proposal.
Although I didn't make it, I hear Syd had a non-religious ceremony for his funeral, and the music included "Always look on the bright side of life". From what I knew of Syd, this really didn't surprise me.

Hi Ian
Been down the lake to see what the state of play was. The Ice is breaking up, But the big news is the water level is up the best i have seen all year . :D O0 {-)

Hi Fellas
Well, whilst I have been waiting for some parts to arrive so that I can get on with the build, I thought I'd get on with the paint. I know its a bit @rse about face, but I was getting frustrated at not being able to crack on with it.
It's taken me ages and there have been one or two disasters, but at least now it's presentable at last. I don't think it will give Simon much of a run for his money at the concourse as the paintwork is not as good as I would have wanted it but you live and learn! Anyway here's a few pix. The stringers and engine go in this weekend and I'll be knocking up the electrics box too with a bit of luck.
Cheers!

Nice looking boat Phil.
You may find it useful to keep the throttle open so you can see the roostertail. Some of the lakes facing partially West are very reflective later in the day and a silver and black boat will not stand out very easily. ;)
Still Simon manages well and his boat is (very) shiny blue!
Danny
The previous tip was given by someone who paints his boats with a yard brush and does NOT get jealous ::) ::) :D

If all else fails, i know ehere you can get a good deal on "solar film" tee hee ;)
-
Yeh - but not until the old lot falls off! That cost me nearly £4, I'll have you know ::) {-)
-
hi Phil nice job looks really well,its a shame you have to attack it with a drill now as i see no holes for handle or for a lanyard ,i don't see any vents in it or holes in the transom..be carefull.........Al... O0
-
Thanks for the feedback fellas. Glad you approve. :)
Danny, I too had a few reservations about the silver colour not being too visible in dodgy light conditions, but then again, it's not that far removed from white which seems to be a popular choice! To be honest, I think I'll probably be going that slowly in the first season that not being able to see the boat will be the least of my worries!
Al, well spotted! I haven't plucked up the courage yet to start drilling big holes in the hull for the strut and rudder etc.! :embarrassed: Although I have to say that I was planning to knock up the stringer frame with an integral transom plate which when it is finally installed will be glassed over and then I will drill through the lot in one go. The transom has a bit of flex in it and as subtlety is not one of my strong points, I thought I had better beef it up a bit!
I also have a couple of ally handles which I was going to fit after I had done pretty much everything else. I am still waiting for some supplies from the US with regard to vents and louvres and stuff and will drill the vent holes when I know the final dimensions of these.
I know it's taking ages, but I am just mindful of the fact that one false move and I could scupper the whole build before it even sees water! ::)
Danny I need to pick your brains if that's ok so I'll PM you O0
Cheers!
Phil
-
hi Phil i love the silver and ill bet it looks even bigger in silver and as Al says its a shame all the holes arent drilled,but it looks nice so far.
keep us posted.
seasons greetings........Pete
-
Hi Pete
Thanks for that. Glad you approve :) [BTW, please can you check your PM? Ta ;) ]
*UPDATE*
I drilled the holes today, cut out the stringers and transom reinforcing plate and offered up the motor on its mounts.
Just need to sort out the radio box now before I drill the holes for the control arms.
Progress at last!
Cheers
Phil

One small hole for man kind! One big hole if you get it wrong! I'm looking forwards to seeing you boat at an OMRA meet next year. Have a good Christmas time. Hide in the workshop it upsets the other half every time. {-)

cheers phil and i hide on my pc with a case of stella, im pushing me luck with my other half but she has'nt gone >>:-( yet so ill carry on {-) {-) O0.
all the best to everyone.........Pete

Phil you don't need to go over board with the vents all it needs is 3 x 20mm holes in the front of those boxes on the hatch and the same on the back and to tidy them up after hole sawing, use rubber grommets...mad...AL :D O0
-
Back from a day at the lake, great weather but boating not as successful.
Flexi wound up and punctured the fuel tank as well as destroying the prop tube. >>:-(
Could not get engine tuned properly so back to the drawring board. :-\
:'( :'(
-
simon who's shafts are you using....mad ..:D.. al : O0
-
The last one i snapped was from Dave M, so i went back to the original PIP flexi from Nimrif. Had to engineer the stinger to accept the wider shaft.
The problem was the flexi got into a bit of a swing and twisted the tube, then the tube split a strand and then BANG, the whole lot stopped.
Should be an easy fix.
I will get a new flexi off Mark Copley, not sure where to get the brass tube from, is it a B&Q job?
Regards
Simon

Simon. I bet you said Whops or words like that???? See Mad makara bit for my account of my days boating. ??? :embarrassed: :P

gentleman, i am just stepping out, i may be some time

-
AL, Pete, Blagmeister where are you and whats happening with your boats?
-
Hi Simon
Sorry not to have been on lately - pressure of work.
Still building the boat - here's the latest pics. Progress has been a bit haphazard of late due to work but nearly there now.
The air vents are in situ now over suitably large-sized slots and I have set the louvres in alternate directions: One forward facing on the starboard side to ram air into the hull and circulate towards the carb and the port side one situated over the exhaust and facing rearward to draw air out and away from the engine bay. The low-pressure effect created by the airflow over the port side louvres should, in theory, draw enough hot air out to cool the bay. Time will tell!
The hatch fixing is a combination of brackets which hook under the trailing edge of the front of the engine bay opening coupled with an adapted aluminium 50mm door bolt which was tapped out and a M4 bold fitted. Seems to be secure enough. I tried using some proprietory clips from PMB first but they wouldn't cut the mustard and regrettably have left a bloody great hole in the hatch so one of them is going to have to stay in place. c'est la vie.... You live and learn!!!
I have also fitted some gewgaws in the shape of an instrument kit from Warehouse Hobbies [where I got the louvres from] which helps add a bit of scale realism and I am just about to order the crew models from BigTee to finish off the cosmetics!
I dropped in to see Danny last weekend and he was kind enough to throw some Makralon my way to help me finish off the radio box which is the current bone of contention. Hopefully I should have that finished and installed this weekend which just leaves the exhaust which I am waiting for from Andy.
Fingers crossed and within the next couple of weeks and I should be ready for a maiden! [Weather permitting].
Cheers

Nice,
glad to see its coming on, love the dash, next visit will be their website!
When are you testing her?
-
Not sure at this stage Simon. It depends on a few things such as when I get the exhaust. Work is looking pretty busy for me too at present so I am having to fit things in around it when I can. Looking forward to getting her on the wet stuff though!

Phil,
I am going testing with Andy with Andy next weekend so i will find out what is happening with your exhaust.
Are you sure about those vents facing forward? Can you unscrew them and change them? Just my experience. I had holes on the front of my dash and then 2 large holes on top of the engine bay covers, i found in a crowd i got allot of water coming in. Lots of rooster tails from other boats.
I am building a new lid as the last one cracked so have opened up the front of the engine covers and have a couple of vents on the back, similar to yours.
Did you fit the autobailer?

Hello
Here's one for all you Zen owners. I need to get new spark plugs for both of my boats. What do you all use??? I have a resitor type plug fitted which makes it a pig to start NGK CMR5H. Any info would be helpfull.
Ta very much
Bill.

Bill,
I got a couple of spares from bluefishy78.com

You need ngk cmr7h my zen starts second pull every time once its primed which is one very slow pull to draw the fuel in with choke on then one good short pull with choke on or finger over breather depending which carb you have then close choke or remove finger give 1/4 throttle and one short fast pull and away she goes oops thats 3 pulls lol O0.

Hi Simon
I can do Saturday, but the Makara is out of action till I get all the exhault bit shorted. So What time ? I will run the Endfrocer boat. O0
Ps did you get the paint code OK???
-
Bill,
What's wrong with the exhaust?
Saturday will be early untill we finish
Got the paint code, thanks, pick the boat up Saturday and go from there!

Hi Simon
If you recall I am having a spacer block made between the engine and the header pipe so it lines up a bit better, and also having the head taped out as the treads for the 2 ex bolts are strip. + a Collier is being made around the ex pipe outlet so it dose not cut its way into the fiber glass. Little tidy up jobs which will inprove it,s reliability. Best get it all done before the racing session starts.
See you at 10 then on Saturday. I will have to be away by 2 as we have a party in MK to go to in the eve.
Cheers for now

Hi Simon
Thanks for the offer to find out about the exhaust.
As for the vents, no I'm not sure, but it seemed like a good idea at the time! I'll give it a go this way around but I haven't glued them just in case I did get drenched and i can swap the forward facing one around so it points back'ards.
I know a lot of others run with big vent holes on the front of the engine cover, but I must confess to being a bit twitchy about that. I would think if water was going to get in anywhere, that would be a good way to guarantee it, but no doubt testing will reveal all.
I bought an autobailer off BigTee yesterday together with some other stuff although it's bloody huge! It would mean another big hole in the hull. Presumably you are supposed to fit these as close to the lowest point as possible. Do you run one in yours and if so, is it any good? Also can you give me any advice on props Simon? I am running the same sort of setup as you did at first with a stock zen, stringers, 21" centre from transom etc etc., so I would have thought a similar prop to yours would do me well.
Incidentally, I can't sing praises for BigTee enough. I ordered some stuff on Wednesday and it arrived today! Compared to all the other model boat suppliers I have tried Tony leaves the rest for dead in terms of service.
Current progress: stringers all fully glassed in now, engine in, radio box completed and fitted into stringers, sterngear fitted. Grab handles and drivers fitted.
Left to do: Paint engine bay, setup servo control arms, fit throttle cable, fit cooling pipes and fuel tank and pipes, fit exhaust.
Nearly there.... O0

Phil
The auto-bailers do work in that they let quite large amounts of water out of the hull rapidly. You are right that they go at the lowest point (usually just next to the shaft). The tube has to be kept clean and you will find that the plastic ball does NOT seal against the 'o' ring completely so, if you stop, water will slowly fill the boat up. Make sure you have enough buoyancy - or a fast rescue! Usually good for about 5 minutes though. I'm going to try a "reverse scoop" under my next boat, with a loop tube to the pickup point at the back. They don't shift as much out, but don't let any in either.
Danny
-
You can make your own bailer that wont leak at all if you stop,mount a flush water piccup backwards through the hull run a piece of coiled up silicone tubing from it into the hull .As your boat moves it creates suction this will draw all the water out but having the tubing coiled up it stops water coming into the boat when stopped,thats the idea anyway.Seen a few guys use this before and talked to a few guys who have done it and it works well.
-
Phil,
I think my auto bailer is 10-11mm wide. Has not sunk yet. Concentate on reliability and you wont need to bother about it sinking! {-)
The prop i use is a Prather 270, i don't think they are available anymore but an equivalent should surfice. I did buy a spare which i believe is an Octura. I am going testing tomorrow so will let you know which is the best.
In standard trim i had her on the gps at 38.4 mphAndy should be working on your exhaust this weekend, got an email from him last night.
Tony is a good chap, he has helped me over the winter and he should be coming up to test with us tomorrow.
What are you using for a radio box?

What motor are you running Simon is it still stock?,try the octura 470 its a good prop also try a 3 blade prop maybe a 6717/3 with rounded ears from chris hoffman O0.$78 including shipping shoot him an email.by the way you can get prather props from here they only have the 280 at the moment but it can be made to 75 or 70 pretty easy O0.But i found the x470 a really good prop on a stock zen,my boats really flying with it,you can get them from Dave Marles he has x 472 in stock or try the ali x470 which is the one i have or ask when he expects the octura x470 in stock,he also has the x470/3 in stock too.The ali one comes balanced and sharp,ive run 2 ali props so far a 78 mm one and the x 470 ,Oh and prather props are still available as they were taken over so props can still be found.

A much more successful day at the lake today, weather was beautiful and company was great.
New cat tuned and running very well, still a bit wet though and now i have retuned the Makara we clocked her at 44.5 mph!
Slight accident with a post so the port chine rail needs a rebuild, something to do.
Having a problem with the stuffing tube spinning. I am using one of those holders from bluefishy, any ideas on locking it more securely??
Thanks to the MMM for another great days boating
BW
Simon
-
Never had a stuffing tube spin on me,what sort of bend do you have in it?,maybe the bend is too shallow which also might account for broken flexes.You need a slight s bend in the tube this actually reduces friction believe it or not.Having less bend can cause cable whip causing the cable to snap just a thought as you say youve had several break.Ive never had a flex cable break to date,granted i dont run every week but just something you might want to check.I allways make my own holders,just plywood with studs and an ali plate over the top bent to shape and tightened down to hold it.is your motor modded now or still stock?,id def look at the 3 blade props O0.heres a pic of the s bend in a cat,same principal though

I also had a grand day out with the southern branch off the MMM. My Endforcer just ran & ran . Only stopping when the driver got it wrong. Oh well you can't have it all!!!!!! :D

Running a 257 carb, a bit of tuning and an X472 prop, was running a prather 270 but swapped it on Saturday and what a difference. Think i will stick with that for the ponds but might go for a three bladder when it gets a bit choppy

hay stavros whats up ? i dont see any funny stuff going on :(

Seems someone who shall remain nameless took offense at me posting helpfull information about stuffing tubes and asked for it to be removed off this thread,martin removed it but stavros saw nothing wrong with it hense his remarks.i was as shocked as you guys ,i wondered where my post went then saw it was on a diff thread , but i will just say i have only offered help to a mate and anyone else who is interested.As far as im concerned im here to talk boats if a certain person doesnt like that then tough.
Simon i am also running the x472 prop and agree its a good prop mines the aluminium version and came very sharp and polished.Never needed to touch it and it made a heck of a diff to my boat,mines still totally stock as i was told the 257 carb isnt much diff to the 644 performance wise especially on a stock motor.Did you get the lightened piston for your motor?,by the way try the 6717/3 for your boat,thats the one i was told by chris hoffman to try on mine.Better still send him an email and ask him which one for your particular boat and setup etc.he quoted me $78 shipped for a modded one O0.

Hi Simon
Thanks for the advice. I think I will hang fire on installing the ball-type autobailer just yet as from doing a bit of research, it seems they can leak after a while. I like the idea of the Bernoulli-driven version so I think I will go down that route in due course, but first I need to get the blo**dy thing on the water!
After your recent success with the X472 prop, I think I will bag myself one of these. I dare say I will be spending the first 12 months testing and developing anyway, so to expect to be quick out of the box is a bit ambitious I think.
As for the radio box, I am afraid I didn't go for a proprietory one in the end and built one out of ply. I also cut a slot out of the port stringer so that it sit across the stern offset to port to keep the rudder servo pretty much in line with the rudder, and to help with weight distribution. [Counter the weight of the exhaust]. The slot means that if [when!] I hit something the box shouldn't stand any chance of getting dislodged. The box itself is a bit of a monster and I have waterproofed it with a coat or three of resin after painting it. Danny gave me a bit of Makrolon for the lid which is held in place by 10 wing nuts onto a double rubber seal. in testing it seemed watertight.
I think in comparison to most people's boat, this thing will look massively over-"engineered" as I have also bonded the stringers in with GRP CSM and loads of resin to strengthen and stiffen the hull which seemed a bit on the bendy side to me. The transom plate has worked a treat and really has stiffened that up so that there is no noticeable flex at the rudder or strut mounting plate.
I fabricated an ally tube brace for the engine end of the tube and this stops any kind of movement at that end.
It probably won't do over 20mph now with all this extra material on board but at least it won't break too easily!
I am pretty much nearing the end of fabrication and can see the final straight. Next step for me is to paint the engine bay with some bilge paint [petrol, oil and water resistant, as well as tidying things up a bit] reassemble all the bits and fit the control rods and then I am done! [That last bit is freaking me out a bit as I haven't a clue on how start the process. I have a good long think about it first I think!
Nearly there....
And then I have to hand the controls over to #1 son who is going to be driving the thing! At least I get to test it!
Cheers!

BERNOULLI thats the name i couldnt remember lol O0,just a heads up fro a good radio box ive just used a sealable food container its a very sturdy one and the lids very tight wont even need tape,its water tight too in tests.Very light too,ive also seen some nice boxes on ebay used in camping they have great lid fasteners too,if id seen this earlier id have got one.

Hello Martin
These boxes? are they any good? What do you use to get the linkages though the Box ??? Bellows ? They look a lot better then the maplin box which leaks. I found out the hard way today. the boat capsized and the radio box was under water for 20 mins till it came back to the bank. OH Dear not one of my better days :( >>:-( :(
-
Hi Bill i havent tried the camping box but theyre suposed to be air and water tight as for sealing the box for pushrods and cables etc yes id just use bellows,on my plastic box i also use a small piece of ply on the inside to add extra thickness where the bellow fits.Not had a box leak so far touch wood.Ive just used a good strong food box we had lying arround and its very strong and the lid seals very tight,water tested it and all was fine.I really like the look of the box i linked though and the lid fasteners seem a good idea,if you try one let me know.

OK fellas, I finally got it finished!
It's taken far longer than I anticipated and cost loads more than budgeted for [mostly due to me buying tools and stuff in order to do the job], but hopefully it will have been worth it. In retrospect, I would do things a bit differently next time. I don't think I would use stringers and would simply beef up the hull with more layup and would use posts for both the engine and radio box. I would also get someone to paint it for me next time as the rattle cans cost a fortune and the end result is not as good as I would have wished.
I think I would also go for a centre or twin rudder rather than an offset one which means that siting the steering servo amidships would be easier. I know there are pros and cons for both arguments but I remain to be convinced that the offset rudder gives massive gains in handling or performance.
It time for the maiden on Sunday at Kingsbury come rain or shine. Can't wait!
Here's the finished pics. Prop by the way is a sharpened and balanced Occy x472
-
Few more details here
-
boat looks great mate and the offset rudder is the only way to go,twin rudders add weight and drag,also inline rudders slow the boat quite a bit.you wont have any problems with an offset rudder especially if your props offset to the right a tad to overcome any prop walk or torque roll.paintjob looks ok too O0.
-
Well Done!!! O0 O0 O0 O0
Lets hope it stays fine for you on Sunday. Don't forget to get someone to video your 1st run. Then we can all see how good she runs. HAVE FUN WITH HER. :D :D :D
Martin. Got the radio box in and it seems to be air tight now i have added more foam seals. Fingers Crossed. ;D ;D ;D

Good looking boat you have there O0 O0
Two observations: I can't tell from the photos if you have bouyancy attached to your cowl, last thing you want is to watch it disappear beneath the waves if it happens to pop off :(
Get some bouyancy in the back and sides of the boat as well, I try to get my boats to float level if they fill with water, stops the radiobox from ending up 60-70cm below waterlevel........
Good luck with the maiden and regardless of the outcome, ENJOY ;D
-
Thanks for the good wishes gents and the kind comments.
Regrettably however, I have already run into snag number 1. I thought I would do a range check for the transmitter/receiver before I drove all the way over to Kinsgbury only to find there might be a problem. Good job I did. I am getting some very weird behaviour from the transmitter/rec setup. It's a Futaba Attack 2ER 40 Mhz by the way.
In the garage with the Tx moved away form the boat and the aerial closed up, I get perfectly normal behaviour - both servos work independently of one another or simultaneously without problem. [If I stand too close to the boat then there is a bit of jitter but I was putting that down to a bit of feedback].
Out in the street, if I get son to check the Tx range by moving away from the boat whilst operating the servos, he gets about 30 meters away and the servos go screwy. Jitter like you wouldn't believe and total loss of control. If he extends the aerial then he gets about 10 feet extra which is hardly worth bothering with.
I had trouble with the fail safe too the other day which would just not seem to hold a signal on any servo so I took it out of the loop and things seemed to be okay until the range test today. I had a chat with BigTee but he has no problems with these units so it leads me to suspect that either the Tx or Rx might be on the fritz.
I have not changed the length of the aerial lead [as everything I have read warns against this, although if I pull the aerial lead out of the tube and hold on to it [acting as the aerial myself] then the range is greatly improved and no jitter. This would seem to suggest that the aerial lead might be too short? There is about 8inches of it in the aerial tube on the transom with the rest inside the boat.
I am gutted that this has put paid to running it over the weekend unless I can get it sorted but I am not going to take the risk of losing the signal without a failsafe and running the thing up the bank and wrecking it after all the hard work.
Any ideas fellas?
Phil
-
Hello.
Just a point about your radio prob.
Is the battery's fully charged. You would not be the 1st model boater to have flattern the battery's when do all the setting up bits. I am still running 40MHz FM so can't help you much other then say Futaba did have a recall on some off there 2.4G set as they all had the same coding. Is yours one off them?? :) ;)
-
Nah It's just a base model 40Mhz cheapy 2ch Futaba Attack Bill. The battery has loads of juice left in it so I know its not that. Battery is brand new too. My money is on the Rx being dodgy as BigTee seemed to think it might be as the failsafe wasn't operating as it should. Dunno whether to throw some money at a new receiver only or to just throw caution [and yet more money!] to the wind and get a totally new setup. It will mean burning the midnight oil again tomorrow trying to get the thing ready for it's maiden, but being this close and then having this problem has ticked me right off.
Phil

Hi Phill
Not sure where you live, I am going to MK (shopping) in the morn but I do have a working Futaba rx if you want to meet up and try it. Simon tryed it out in his boat a few weeks ago so I know it's a runner. Be back in a bit dinner calls
-
Very kind of you to offer Bill but I think MK is a bit far. [I am in Nuneaton]. I think a trip to the local [?!!] model shop might be in order early tomorrow morning. Do you think about 8" of aerial lead inside the tube is enough or should I re-site the Rx inside the box to give me an inch or two more?
-
Hi . I get as much Ariel out off the boat as poss even if I have to have a small loop at the top of the Ariel. I did if you look back have probs with a Hitec Rx which i was told was the bees knees. Sadly it was not. Now I am using a very cheap 6 Chanel Rx which I got on e bay from hong Kong £8.50 inc p&p. So far it has worked spot on. I am pleased to say the chap that sold the Hitex to me has now got a sparky boat himself with a Hitex Rx and he is all so having range probs. Its fine with glow plug engines, but there is something about the HT on a Zen which upsets it big time.
-
Phil,
Its always worthwhile having a spare receiver anyway. I use the futaba 3 channel with built in failsafe and they are fine as long as you dont drown them.
Well worth taking the aerial out and trying it in various positions first. Does sond like a battery problem though, might be worth discharging and recharging to be on the safe side, no costs to that!
Quick trip to the model shop for a new receiver, about £40 and you will always use it!
Boat looks great, well built and over engineered!
I see you offset the strut in the end.
Look forward to racing with you!
Martin, i clocked mine at 45mph a couple of weeks ago!

I have to agree it sounds like a battery problem to me too ,if your thinking of a new radio try the futtaba fasst 2.4 ghz systems theyre great ,no glitches and no crystals .Simon sounds good mate did you get that lightened piston and some porting done i take it?.No mean feat getting that big boat to that speed ,it would give my boat a good run hehe.i got a new prop modded by chris hoffman on its way its a 6717/3 should make it go well ;).
Mart
-
Phil, Been thinking about your Rx. If you can get the case off it , check the Ariel is soldered to the PCB. I have had one which parted company and gave me short rang probs. O0
-
Thanks for the advice guys. I will pop the case off tomorrow and check the PCB but in the meantime I think I will take Simon's advice and see if I can get a new Rx with a built in failsafe. If you have a model number Simon, that would be useful. Off to the modelling shop tomorrow to rid myself of a few more £££ ::)
Determined to get the thing on the water this weekend!
Cheers fellas

I have been having a mooch around and came up with this: Futaba R143 Rx with Failsafe on chan 2.
Is that the same as yours?
But.... I also found this:
"The R143F receiver cannot be used with dry cell or NiMH batteries. These batteries cannot endure a large current draw and will drop in voltage frequently if used with this receiver."
Source: Here (http://cgi.ebay.ie/Futaba-R143F-FM-w-Fail-Safe-40MHz-w-o-Crystal_W0QQitemZ260210815445QQihZ016QQcategoryZ34056QQcmdZViewItem)
Could it be that these Rx are cheapy HongKong copies and thus aren't much cop? Oh! the frustration ;)
I just bought 2 X Nimh 2700MaH 5 cell AA last week. :-\ B*gger........
-
Right couple of questions
Are you using a separate failsafe or are you using a R143 receiver.
Have you spoken to the model shop where you bought the set
I have used a attack by Futaba on more than one occasion and never had a problem with them 100% reliable over 300yds range with a yacht so I personally think you have a transmitter problem rather than receiver as simply I have had exactly the same fault with a 6exa Futaba which went down and also a Hi tech set,and incidentally both corresponding receiver are still going strong in the boats.

Very nice looking boat - you should be proud of it!
Couple of things - you said
"Out in the street, if I get son to check the Tx range by moving away from the boat whilst operating the servos, he gets about 30 meters away and the servos go screwy. Jitter like you wouldn't believe and total loss of control. If he extends the aerial then he gets about 10 feet extra which is hardly worth bothering with."
If you are getting anything over 5 metres WITH THE AERIAL DOWN then there is nothing wrong with the Rx or it's aerial! If the range only goes up a few feet with the aerial out then I would suspect something wrong with the TRANSMITTER aerial. Receivers are very forgiving regarding aerial length. I usually chop mine off 30 cm from the Rx, stick a big bullet connector onto it, then the other side of the bullet conn to a spade connector which plugs onto the bottom of a piano wire aerial fastened to the top. The only problems I've had are usually flat batteries (or a single cell down) but if you've bought new batteries that's not likely to be the problem.
Hitec Rx's (especailly the red ones for some reason) tend to be very twitchy with a weak signal but if your Tx is OK they are usually fine.
Give me a ring tomorrow morning - I have a few spare sets you can borrow to try out (01788 813339).
Check you haven't had any water down the Tx aerial which may cause corrosion. Try unscrewing it and put a smear of Vaseline on the thread end.
Ian is right about the foam. Split one of the 'tubes' and superglue the flat part onto the inside of your lid. Also squirt a bit of builders foam or silicon sealer between the tubes in the front of the boat to hold them together. Even if they feel really tight, they will vibrate loose and could slide back against the exhaust!!
You've done the hard bit - just the tidying up now O0

The only Futaba Attack 2 ER I can find is an AM radio. I would not advise the use of an AM radio with a gas boat the chances of interference from the ignition system are too high. :(
All that time and money in a boat, is it really not worth a better radio..... I would use a minimum of a FM radio (better still with PCM or IPD) or a 2,4 system.
-
Phil,
I am running the Futaba R143F and have not had any problems with nicad or nimh?
Danny is the man, so if he has spares and is local def worth a try. As far as the foam is concerned you have to secure it. Mine was fine when i built the boat and went testing, in my fisrt race i spun out and deposited the foam all over the pond! I wold not use to much of that foam though. Very difficult to get it out.
let us know how you get on.

Is this the radio you have? if so change it for FM now dont run an AM radio or your loveley boat will sail off into the blue yonder and smash into something at full tilt i guarantee you.If it doesnt happen first time its only a matter of time AM is renowned for glitches especially with an elec ignition system.

Hi Fellas. Many thanks for the prompt replies.
Stav - I was using a separate F/safe but it was not getting a consistent signal and would not work so I took it out of the loop. I bought the Tx/Rx set at the Warwick show last Nov. Prolly not the best place to buy one but I was tempted by the offer...
Danny - thanks for the compliments and the offer of a lend of a spare set. The more I think about it, the more it sounds like a Tx problem which would explain the f/safe I got from BigTee not setting properly. If it wasn't getting a strong enough signal from the Tx then of course it would keep failing as it was designed to do! I'll have it to bits this morning and see if I can see anything like a dry joint or something. I'll try your suggestion with the vaseline too. Re: the foam, I am going to put some more in as soon as I have got everything else snagged but until I have a fully functioning system, I thought I'd leave it out just to make access that little bit easier. I have plenty left so once everything is functioning properly, it will be out with the silicon sealer and then a bouyancy fest!
Webby - It is a 40Mhz AM system so having said that, I think you are probably right and a better system might be in order. As you say - shame to spoil the ship for a ha'porth of tar!
Simon - glad to hear that your R143F works ok with Nimh. I think that whatever I go for, if I can get something with a built-in failsafe then it makes sense to do so.
Mart - good advice and thanks.
Conclusions are that it sounds like the Tx might be on the fritz, then again it could be the receiver. The separate failsafe I have won't work with the current setup due to the anomaly. There is some ambiguity with the whole setup therefore I shall replace the system. Off to Brum now..... Let you know how I get on later.
Cheers!
Phil

40Mhz AM is not good news. :( Best off luck with your maiden voyage on Sunday O0 Don't forget to take a video cam with youu.

Hi Martin.
All Done ready for a run Sunday morn. Lets hope it stays sealed up ;D ;D

Hi Phil best change the radio to fm also with failsafes if there is a lack of power in the battery they will kick in so make sure you runa 5 cell hump pack for your rx,the bigger the cells the better also.Another thing too is run a y lead in yoiur setup between rudder servo and battery this ensures a full 6 volts gets to the rudder servo at all times O0.There are some decent cheap fm radios arround if you dont want to spend more on a futaba fasst system ,but i find the fasst system great and not having to worry about clashing with others is a bonus too.I got my 6ex from the states for less than a hundred quid shipped almost new and it works great.Mines intended for helis so has 6 channels ,bit overkill but it was a good price so went with it,it has 6 model memory which comes in handy and also a built in failsafe ;).Just dont go spektrum as they have issues on water or some have,futaba fasst systems dont O0.That said if you wanna save money get a decent fm radio you can pick them up for arround 50-75 quid.I was running a cheap hitech zebra radio with not problems at all i just chose to go to the fasst system to save messing with crystals .

Hi Martin.
All Done ready for a run Sunday morn. Lets hope it stays sealed up ;D ;D
Looks good Bill if it were me id runsome elastic band a zip tie or anything from one fastener to the other to stop them popping off in a flip ;).Hope it works good for yaa ,my tupperware box is about same size and the lids very strong and water tight in tests ::) tip for yaa stick a tampon or two in the radio box to soak up any water that might get in and that will keep things dry hopefully O0.checkout my build thread for my stepped vee some videos on there of it too.

;D ;D ;D ;D
I'm a happy bunny now!
After much debate this morning, I grasped the nettle and went out and bought a nice new 2.4 Ghz Futaba 6EX setup. What a difference!! Much better. No problem with range now! Having said that, I think you need a degree in electronic engineering to set the damn thing up! At least I got it most of the way there and it all seems to work ok. So, a little fettling later and Jnr and I thought we'd sneak a quick half hour in over at Kingsbury before it got too late in the day.
;D Well it runs! Takes a bit of starting [always seems to need about 3/4 choke to start it, even when warm then I need to idle it at about 1/3 throttle for it to stay running after knocking off the choke]. The first chuck resulted in a stall so it was out with the club rowing boat. I tried again and managed to get a bit further this time before it stalled. It seemed not to want to open the throttle. I could run it at about 1/3-1/2 throttle and as long as I didn't change the throttle setting it was okay. Running very wet though at this stage and the engine seemed to be hunting and the prop cavitating. I got a few laps in at this setting though at least before it stalled. As soon as I opened the tap a bit it fluffed to a stop and it was out with the rowing boat again. I figured it might be running too rich so I leaned off the H screw a bit and blimey! what a difference! It frightened the life out of me! It sat up screamed and round the lake so I backed it off a bit then and again it stalled after a few laps.
I think the carb settings are all to cock but as I don't really have a clue with these engines, any advice anyone has to offer would be useful. It handles very nicely though, runs straight and true, no prop walk but a bit of porpoising. Strut angle may need a tweak but again, those in the know could prolly do with seeing it.
Regrettably no video footage of this maiden, but I don't really consider it it's first "official" outing. I'll try again tomorrow and with a bit of luck get some video footage. Incidentally if any of you guys are off out tomorrow with your boats, if you let me know ASAP, I'll try and get to you with it so I can pick your brains re: the setup but failing that it's back to Kingsbury and a bit of trial and error.....
At least it didn't sink! O0

Hi Phil
Well done on your maiden trip. I Will be out at Stevenage in the morn having fun with mine. Let's hope my new radio box stays water proof. I tip my boat over lasat week at Brentwood. This was when i found out maplin water proof boxes an't . Radio,Engine, fuel tank was all under for 20 mins . Not what I had in mine for a fun day out.
-
Unlucky Bill. Sorry to hear that. Hope you have finally managed to get it sorted. Do you have a rescue boat at Stevenage? 20 Mins is a long time for a radio box to go swimming. I think I managed to get out to mine today in about 5 mins of it stalling each time. [Not that it was underwater of course but having the rescue boat at my disposal made a rotten situation into a half decent one if you know what I mean].
If you let me know the details of where and when you are likely to be at Stevenage I may see if I can convince SWMBO that I may need to get up early tomorrow to go testing...... Just make sure the rescue boat is to hand!
Cheers
Phil
-
hi phil , good to here you got her on the water ;D
i take it you are running a standard zenoah / 644 carb combo ? what is your oil / fuel ratio ( how much oil to 5 lts of fuel )
the amount of oil will have a big effect on setting the carb up , but a starting point is 1.5 on the L and 2 on the H
another good tip is to take out the choke complety ( starting not a problem just choke using your finger ) this will help to get more air
into the engine and help it breath better
let me know if i can help

Hi Phil
You would be very welcome to come along and join us. We have the use of the lake from 9-12 . Yes we do have a boat with a very helpfull young member of our club who needs the practice. The entry to the lake off a road called" Six Hill Way" If you go on the OMRA site and look up the meet on the 4th May there is a map there to find us. We are allowed 5 car lake side parking, but we can short out something if you come down all that way. Will send you a email ASAP with my moblle . Look forwards to seing you. Bill.

Congrats on your first outing Phil glad you got a new radio too O0,on my stock zen i run 16/1 mix full synthetic oil.My needles are 1 3/4 low and 1 to 1 and 1/4 on the high.That should get it reving and keep it running O0.Heres a nice tool to help work out your fuel mixes too ;).

Yea thats the idea ,works good for close in any further than say 30 -50 mtres and its dificult to reach.its just the butt end of the rod, an old sea rod and big real 30lb line with some cord attached to it via a loop which is threaded through the tennis ball and knotted the other side.My mate also built a rescue boat using an electric boat and some plastic tubing and some insulation foam to make the rig float simply drive out collect the dead boat and push it back.It works great too heres a apic of a similar one.
-
A big thank you today for Bill for inviting me down to the Stevenage club for a bit of testing and tuning. That side of things went well and the carb settings are much better and the boat now runs for as long as I want and is throttling much better too. A bit more testing should see it perform as it should. The CoG needs a bit of work as there is too much weigth aft [probably thanks to my over-engineered radio box] and the nose definately needs some weight as it was lifting like mad in a head wind, so much so that I had to back off the gas quite a bit.
One thing didn't quite go to plan though. I was getting a little enthusiastic with things and in view of the spray that was getting into the hull, I thought I'd run with the lid on. [Bear in mind that I hadn't as yet fitted any flotation to the lid and the tin of spray glue I was going to use to stick the foam to it was jammed into the forepeak acting as temporary ballast. I did another run with the lid on and it was going very well - lap after lap completed with no sign of anything untoward....... Right until the lid came off. And then sank. :embarrassed: Bugg*r...
The hatch fixing is a combination of brackets which hook under the trailing edge of the front of the engine bay opening coupled with an adapted aluminium 50mm door bolt which was tapped out and a M4 bolt fitted. Seems to be secure enough.
Evidently not secure enough! You live and learn... Back to the workshop!
Cheers
Phil

Two observations: I can't tell from the photos if you have buoyancy attached to your cowl, last thing you want is to watch it disappear beneath the waves if it happens to pop off :(
Right until the lid came off. And then sank. :embarrassed: Bugg*r...
I did try to save you from that one... Other than that it sounds like you had a good day at the lake ;D
-
You did indeed Webby and so did Danny too! In my defence, I have to say that even though I was mindful of the possibility, [and I thought it was a slim one, AND I only intended to be out for a minute or two with the hatch on], I was enjoying myself too much to worry about it! A classic dose of over-enthusiasm! ::)
/me shrugs
Cheers! O0
Phil
-
Congrats mate seems like your getting there pitty about the lid :o,have you done the broom test as regards balancing the boat.balance should be arround 30 -32% from the transom on most boats.if balance is ok and fronts still rising you can either use trim tabs if you have them to correct it or alter the prop angle a tad ,also tucking the rudder in a touch will make it run a little wetter.
-
Hi Martin.
The radio box seems to of held up. Got to do a bit more work on the exhaust coupling then I think my winter trails will be over.
Phil's boat is going in the right direction. The nose was a big high and prevented the boat from going full chat. Putting a bit of extra weight in the front end did very much improve things. I don't run any trim tabs on mine and it is very steady in the water. So it must be down to the heavy radio box in the rear which needs a bit of countering.
-
PS I meant to add Well done Phil for a nicely turned out boat. Pitty about the top but IF it dose wash up we will let you have it back. You are welcome at Stevenage any Sunday morn where help is only a conversation away.
-
Glad to hear it worked out mate,best way to balance the boat is not to add weight been there done that ,maybe a bit of down angle on the drive will help but first try angling the rudder in towards the transom a tad that will bring the nose down a bit depending on how bad it is i guess.Maybe moving the fuel tank forward would be best idea rather than adding any more weight?.but def try the rudder thing.

Mart
Mart,
If by angling the rudder in, you mean the tip of the rudder further forward than the top of the rudder, I think you've got it the wrong way round.
The rudder, and anything else touching the water at the transom end will tend to lift the transom, and therefore bring the nose down. Angling the tip (bottom / submerged end) of the rudder in (nearer the transom) will tend to direct some of the water flow up the rudder, and reduce the lift from the rudder, therefore raising the nose. This will be most pronounced in turns, but should have a similar but lesser effect with a straight rudder (assuming that the front to rear cross section of the rudder is wedge shaped). Angling the rudder the other way (tip further back than the top) will produce more lift from the rudder - therefore raising the transom more, and pushing the nose down. Again, this will be more pronounced in turns, so angling the rudder outwards to lower the nose is likely to result in "bow steering", and spinouts.
As regards balance point, my opinion (mostly gut instinct) is that this should be positioned so that the boat flies at the right attitude when it comes off a wave, and lands at the right attitude. For a deep vee, surface driven, this should be slightly nose up. If this is right, but it porpoises, I would try and adjust it out with driveline adjustments or trimtabs. If it flies wrong, adjust that first, then trim the driveline etc. If it flies wrong, it will be horrible in the rough (personal experience there). It's quite hard to test without rough water though.....
Still working on getting my new AA boat to handle, but having trouble getting enough time on the water without breaking anything.

Ian your completeley correct mate ,sorry if i confused anyone i angled mine forward a tad to raise the bow as mine was running wet and digging in in the turns dont know how i made that mistake ::).i meant to say angled back of course dohh.

But Martin you may well be right it dose seem very quite round here. The 1st OMRA race is at Eastbourne next week. Maybe they have all got there heads in there boats. :) I can't make it next Sunday as I have a prior arrangement . It whould be a hell of a drive from Great Yarmouth to Eastbourne and back again.

Did she over heat cooling problem maybe? not enough oil in the fuel doubt that ? what broke ? did the whole head explode or just near the exhaust manifold.maybe the pipes too heavy not enough flexability in the exhaust setup?.im thinking out loud here as theres been a few problems like these on other boards with the problems i mentioned.wouldnt want it to happen to your new sikk.I ran my boat today in 8" chop man that was scary did a complete submarine at 38 mph,that was the fastets speed i got from her on the day ,that was at 3/4 throttle in rough water running a new 6717/3 prop man what a diff it made scared the hell outa me in those conditions.Should be fast in better water O0,too scared to give her full throttle today ::).Posted a short poor vid on the seaquell thread.

Cheers for that Martin.
Been doing a bit in the shed. I have a 90 pipe which I am going to try out. If not I may end up taking the pipe out of my old boat for a try. It is being used on a Zen 26. Lots of things to try out . I think the MKZ pipe is to big and may have caused the prob. As and when it rain stops I will sart the new engine up.
-
What .90 pipe is it? i have one i was going to use on a zen its a rossi .90 pipe i believe ,no water cooling but has built in silencer wether ill use it i dont know its black coated with heat proof epoxy coating or something?.i orriginally wanted it for my strimmer motor but couldnt get a header to fit the motor without major work so its only been used once to test.is yours anything like this one?.
-
Mart,
That does look like a Rossi pipe, and by the length, I'd guess it's the .90 version (I had a couple of their 40-60 pipes).
Bill,
Just thinking, how about a clamp - to clamp the header pipe to or around the block somehow. I guess the biggest challenge would be the position of the carb / inlet and the fins. If you can fashion something up though - so that the weight is not hanging on the mounting bolts, I reckon it can only be a good thing.
As an example, I've seen arrangements for nitro engines with a cut jubilee clip - where the ends bolt to the header, and the clamp goes around the block. I know it's not quite that simple on your engine, but I'm sure there's a way there somehow......
-
Hi Ian
Yes I no what you mean. I have now got a Alloy 90 pipe in it now with a rubber mounting holding it on to the boat. I just think that MKZ pipe was to much. This new set up is lighter and better surported, the engine move freely on the mounts without any think stopping it. Just fitting an oiler to the flex now.
Barry (bluefishy) told me I have to run the new engine in at 1/3 power for at least 3 Lt of fuel. Thats going to take about 1 1/2 hr on the water. Oh happy days.
Been thinking I could bulid a outrigger out of the old engine during next winter. I would like to see there faces at the lake if I did >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-( >>:-(

What, you mean with the same crankcase ? That would turn a few heads.
I remember one of the first OMRA races I went to at Eastbourne, someone turned up with an Enforcer ManO'War, with an unsilenced pipe on a Zen. Now that was loud.....
The young un' at our club's already doing his best - running that Merco 61 with air-coupled manifold. Maybe we could have a "no silencers day". I've got a few unsilenced nitro pipes at home. They should really howl a treat on some of my engines. I'm sure Greg must have some too. We might need to line up a new lake first though.....
-
Bill what pipe are you going to use on the new header ? if you use one with o rings that will give you enough movement as to stop any unwanted vibration issues that can cause failure at the exhaust flange .My hanson just hangs on the header and isnt supported till it gets to the transom then i use a piece of high temp silicone from a rc car exhaust round the pipe where it exits the transom i cut the exit hole a snug fit and thats all that holds it in place it doesnt vibnrate or move at all ,works a treat.i do have some wire running from one of the water cooling nipples on the exhaust to a jubilee clip on the header pipe that stops it sliding out and losing its tune though.
-
Hi Martin
I the pipe came off a 90 Helli. The header pipe fit's in side a lose salve which then has Silicon tube over the joint. It all seems to move enough. It has a mount via a rubber vibration cupling to the boat. The whole things seems to move around OK.
I ran (on tick Over) the engine today and it sounds sweet. I take it while running in period you should add a bit more oil in the mix.
I may well get home on Thurs to get to or local lake to give it a run. Slowly of course.
Bill
-
one tip for you is swap the silicone for teflon as its more heat resistant the silicone ones melt very quickly :o,as for running in i dont run more oil just run the motor rich and vary the throttle.i was told to run for 5 mins upto no more than 1/2 throttle then come in let motor cool completeley then repeat the process a cpl of times each time staying out 5 mins longer.Then once the tank of fuel has gone your good to go just dont go mad till youve done a few tanks and allways vary the throttle and short bursts of power till you feel confident shes run in ,16-1 oil ratio,some run non synthetic for first few tanks then swap to full synthetic but i never did that i have allways ran it on full synthetic oil and my motor runs sweet as a nut.Heck some guys over the pond dont even bother running them in at all and they get along fine .

Hi there martno1fan, been reading your posts mate and you seem to be in the know. What class do you race in and what would you say would be the best class for a newbie
to start in ?
Have you taken any video of your boat actually racing that we could see ?
-
Well the rain held off long enough to get my new engine running in the water. Even at 1/3rd full throttle its seems to be a very happy result O0 O0 O0 O0 O0. It should be a big improvement on my old engine. The pipe seems to be working fine. Not to much noise , so the rest of the Stevenage MBC are not complaning. Looking forwards to a lot more running in and then full steam ahead. {-) {-) {-) O0 O0 O0 O0
Good to here from a model boater from NZ.

kit,
Mart has not managed to jin us for a race yet? If you want to see some video have a look on utube under windemere dolphins or omra85
I started racing last year and for easo of getting on the water and running costs D class is by far the easiest. spark ignition petrol boats up to 50cc. nice cheapish petrol and easy to start. Well compared to glow motors.
Do they have a series in NZ?

Hi Kit racing isnt my bag to be honest im juts a sports boater,racing gets too full on id rather just enjoy myself ;D.Simon they do have a boating body in Newzealand my mate lives there.Not sure what kind of racing they do mind ?.Bill im glad shes working out for yaa mate,im serriously considering a sikk for my hydro as they come with mounts which helps {-).
Mart

Hi Bill just a warning for you theres been a few sikk motors doing this in the states,seems the white gasket on them is the culprit as its too soft and if you over tighten your piston has little to no clearance and oops and so they change them for a blue one or copper.You might want to check which one yours has just in case?.The two bolt head doesnt help especially if you flip i guess,seeing this has made my mind up ill be sticking with zenoah.Have a read here>> free to sign up .

Off to Eastbourne for a whet and windy start to the 2008 racing series.
Fingers and toes crossed!
Picture of the new paint scheme, not sure whether th add the Red Bull stickers.
What do you think?
Regards
Simon

Well Simon,
I have to say I think the new colour scheme looks great! Very upmarket feel to it! 8) Personally I think you should add the Red Bull decals so that there are at least 2 of us with motorsport stylee paint schemes!
Regrettably, as you probably realise, I didn't make it to Eastbourne today. I finally got my boat finished late last evening at about 5pm and shot over to Kingsbury for a quick test and to try to get it to run a bit better. Sadly, it was still porpoising like mad and after fiddling with the rudder and strut angle and then finally spinning out in an explosion of spray and 2-stroke smoke, [I managed to keep it going but narrowly missed bisecting a swan in the process!], I decided to call it a day as the light was fading fast.
When I got back home I started to do a minor strip to clean it up and as I was emptying the bag tank I noticed it was spraying fuel everywhere from a pinhole! An errant fibreglass strand must have pierced it. :( My test bag-tank is only 500ml so no spare tank, so no racing. In view of the way it is handling, it was perhaps a blessing in disguise as I would have probably trashed either my boat or someone else's with the way it is handling at present. [I had said to my lad earlier on in the day that Fate clearly didn't want me racing this weekend!]
So....
Discretion [and the need to get it running straight before swapping paint with some of you guys] being the better part of valour, I elected to stay in home waters today and get some testing and more running-in under my belt. I spent a good 4 hours at Kinsgbury today and bumped into Andy Rennie who very kindly gave me plenty of sage advice. The boat is now throttling very nicely [even thought it is still a very long way from being run-in], but no matter how much weight I chuck in the bows, it still porpoises to varying degrees. Also, when I give it the beans, it starts to get a bit of torque shimmy on it :o so it looks as though trim tabs are on the cards, according to Andy.
Back to the workshop...... ::)
I hope you all had a great day [in the wind and rain] and all the boats came back more or less in one piece!
Cheers
Phil

hi phil , glad to here you had a run today but no fuel tank / bag is a pritty poor excuse for not coming down to eastboune today ;) ;) ;) ;) ;) alway some one to lend some one some thing !!!!!!!!!!!!!!
weather prity poor but you and the others missed a good days racing with two , yes two heats in some windy chopy condictions

Thanks Tony,
Well i can proudly say that not only did i turn my boat over, but my claim to fame is.......................................
I SUNK THE RESCUE BOAT AS WELL {-)
So there i am sat in the middle of the lake up to my you know what in a sunk boat wondering what to do, stepped out of the sunken boat and it was about 4 foot deep!
Spent the rest of the day trying to dry out, waterproof boots are great, but keep the water on the outside. :'(
And did i get a medal, well only PLONKER of the day.
I am sure the pictures will turn up!

man that was funny :D :D :D :D :D :D
thanks for your help today on the hill , good racing , good condictions
tony

Dang! I would have liked to have seen that Simon {-)
I hope Scoop got the pics - the World (wide web) is waiting ........
You seem to have recovered now O0 It's a fairly exclusive club - sinking the rescue boat FROM THE INSIDE. I hope you haven't been disqualified from rescue duties for the rest of the season ::)
Make sure you have your lifejacket on at Torquay - it's a bit deeper than 4ft I believe {-) {-) {-) {-) {-)

One up on you Danny. At least Simon did something worth mentioning.
By the way, see you're not in Model Boats again. (http://i124.photobucket.com/albums/p8/DickyD_photos/crying2.gif)

No Richard - it's a quiet life for me now. I've had my 15 minutes, I'll leave it up to these youngsters to have all the fun (insert lemon in wheelchair Smiley here).
Oh yes, Simon's going to be famous for sure {-)

Just Got Back from a weekend away. (sadley not boating) What did you do Simon??????????????????????????????????????????
I have just got to see the pic's
Waited for your text last night. I take it your phone got wet then :) :) :) :)

Dose anyone have the race results from yesterday.

Hi Tony
Bubble bubble . OPP'S
-
Who came 1st ,2nd, 3rd in the D class ???
-
Tony came first and then a couple of local lads.
Your chances for the championship are safe!
Sorry i did not phone/text. Had kinda a quiet journey home without the phone, and today! New one ordered will be here tomorrow.
Bernard phoned me last night and he is sending me the only picture. Ha Ha.
What would you like to start the bidding at?
Bill, real problems with glitching? Changed engines, plugs, receivers, any ideas. Do crystals go off?
BW
Simon
-
Nice one Simon.
Have you tryed your spark plug? Changing mine sloved all my radio probs. Im useing a NGK CR8HIX Iridium plug. I did not change the plug that came with the Sikk engine and that seems to work without upsetting the radio. Before you think about a 2.4 set read model boats mag. There is a model shop in Hitchin who is doing a Spectrum set for £100.
-
Changed the plugs.
Thought i had got it sorted testing at Brentwood on Saturday, come race day the problem is back?
>>:-( >>:-( >>:-( >>:-( >>:-( >>:-(
-
Pass Simon. I take it you have chaged the RX ? How are the cables on your battery pack. The old black wire cause all shorts of probs. All of which I am sure you have looked at .
-
I am going to relook at the aeriel set up.
Change the crystals
And if all else fails i will borrow Martin's 2.4 and see what happens.
Going to try out a new lake in SWF Friday weather permitting? Are you coming out to play?
-
Not sure where you mean Simon. Anyway I have got to get on with the painting. Her indoors wants it doing. I hopfully will be let out on Sunday.
-
I will be over at my parents Sunday, Brookmans Park. Want to meet up?
-
Friday May just be on. She is now saying as long as I get stuck into during the week nights I shoul be OK. email me where and when.
Is there a rescue boat for you to play with?? {-) {-)
-
OK Talk closer to Friday
-
Well i have just heard from Bernard and i should get the pictures tomorrow in the post.
Should i scan them in and post them on the site????
::)
-
YES!!!! :D
Hope your strides have dried out by now Simon! ;D ;D ;D ;D ;D ;D
Having spent years messing about in big boats, I can say that boating without getting a wet bum, isn't really boating at all! Nice to see you still keeping up the tradition! :D
[Disappointed not to get down to Eastbourne at the weekend to meet you all, but looking forward to the next opportunity, hopefully with a fully sorted boat!].
Best regards

Hi Simon.
Well we are still waiting for the pic's of last Sundays boating incident. O0 O0
Where are we going on Friday.? Seems I have my pass out for the day.
-
I scanned the picture but it wont upload so you will have to wait until Friday.
Brentwood, if that OK
-
Brentwood at 9.30-10.00 Sounds very good to me. Let's hope the snow keeps off. I better get the battery's charged up on both the boats. Still got to run some more fuel though my engine before I can open her up. Should be able to do that at Brentwood no prob's

Simon
Send me a copy by email - I'll keep it secret - honest O0 ::) ::)
You know you want to ;)

Dont you dare Simon, we dont want Danny gloating on his own. We all want to do it.
Did you scan it as a jpeg ?

Thanks for the invite Simon but I am off to Wales for the weekend to see some friends and to do some messing about in big boats. I am planning on taking the boat if my new trimtabs arrive in time to get them fitted beforehand though! I need to get some practice in on the lumpy stuff for the Chase Race! I am not convinced that going form nothing straight into deep water is a good idea without a bit of practice beforehand!!!
I hope you and Bill have a good session at Brentwood on Friday and the weather holds for you.
I'll see if I can get some pics over the weekend and I'll bell you when I get back.
Have a good 'un and hurry up with those pics of you at Eastbourne! :D
Cheers

Hi Chaps
Simon says - "Brrrrr, that was COLD but I can still smile about it!"
Have a look on the OMRA front page (or a bigger one in the photo gallery)
Never mind Simon, 2008 can ONLY get better after that.
Cheers
Danny
-
Phil,
Hold off fitting the trim tabs, none of us are running them and we have not got a problem. Bring the boat down and lets have a look at it next to some others, hopefully we can see if there is a problem before you go drilling even more holes in it.
Regards
Simon

Quick hijack... Danny, when are you going to fix the OMRA site so that it WORKS for all visitors, not just micro**** users? good show on the front page but it would be nice to get into the site as well......
-
HERE HERE. Since I did my last MS software up grade I to cant open up the OMRA site. I have to say how disappointing that is because there has been some real good stuff going up on that site. GO ON DANNY DO YOUR STUFF. :'( :'( :kiss: If that is a tall order at the mo. How about putting some of the stuff on this site, like the race results and meeting details and Simons sinking {-) {-) Thanks Danny.
Your Unable to get into the OMRA site

Too late Simon, I have already fitted em! C'est la vie. I'll let you know if they make a diff.
Danny if you need a hand with the site design and functionality please let me know. I too have had issues with the new site as it won't workl in anything other then IE. If you would like some help, please let me know as I have a portfolio of a fair few sites under my belt over the last 12 years and would be happy to help out if needed.

Hi chaps
I know I'm nicking the thread but a few people seem upset that I haven't got the OMRA site totally optimised.
I'd like the opportunity to explain what has happened.
Last year, I was getting totally p***ed off with the fact that the OMRA website never seemed to have up to date information. I now know that the guy looking after it had other things on his mind and the site took a back seat - these things happen.
I brought up the issue at the AGM and (not unexpectedly) was asked if I'd be prepared to do something about it. Now me being me, feel duty bound to put something back into the hobby, so agreed to try and do something with the site although my knowledge of websites was NIL.
At this point, the only contact I'd had with a website (apart from viewing it) was to notice that there was an additional 'bit' called "Frontpage" bundled in with the copy of MS Office I'd got from work (apparently you can have a copy on your home machine as well as at work, providing you don't use them both at the same time??)
Having spoken to the ex-keeper of the site, I found that the whole OMRA site had been created in Frontpage. I spent 3 weeks studying FP enough so that I felt confident that I could make changes without bu**ering the whole site up. I then spent another 12 days designing and copying/pasting, moving, adding graphics, etc to get what you see today (or don't see as the case may be!).
Immediately the 'new site' was launched (a truly heart-stopping moment!!), I found that it could only be viewed with Internet Explorer! My own version of Firefox (which I use at work as it's FAR more reliable than IE) would not work. I have since found that this is because Frontpage creates buttons and some text as graphics which are merely 'viewed' by Netscape type browsers!
To say that I was disappointed would be the ultimate understatement!
I have since started to recreate the site in something that would be usable by all parties (Serif Pageplus) which I am happy to do but as my original site is quite large is taking some time. It's not just a matter of cut and paste because some of the functions are different. I have also began studying HTML which I thought might help me, but to be honest, it's a bit like preparing to drive a HGV, having studied how to blow up the tyre on a moped (weird analogy or what!).
The bottom line is, that I am working on it on a nightly basis (as well as trying to build a new boat and go racing) which should be viewable by all (the site OR the boat).
I would be grateful if you could help by (temporarily) getting a copy of Internet Explorer, and using it it just for viewing the OMRA site (I'm not asking you to support the master villain - Bill Gates)! You don't have to use it for anything else (so you're conscience will be clear) until I've had time to recreate the site in "pure" html, which will be viewable on anything (hopefully).
An interesting mental exercise for which I'm glad I volunteered ::)
Thanks
Danny
PS Hope there's a picture somewhere of Simon sitting in the semi submerged rescue boat, with the water up to his waist??
-
Danny,
Whatever all that means, thanks. O0
To take on the website, get it up and running and prepare and race boats in mind mind has got to be hard work. So well done. ;D
So when will the new boat be ready???? Sneak preview???? sticky tape graphics and all. {-)
I have seen my picture on the site so thanks very much. At least it will give the rest of them a laugh and no broken bones.
Do you remember that conversation we had about a year ago about me being the shy retiring type? :angel: I did warn you!!
:D :D :D :D :D :D :D :D :D :D
Keep up the good work and hope to pit for you again soon. Hi to Lynda.

Hi Danny
Fair play to you for taking on the webmasters job - it's not an easy task. I administer a number of sites, including my own and I know just how much work goes into them. The OMRA site is not that big [mine has in excess of 80 pages and is quite big] and frontpage will handle it without a problem.
Don't give up with Frontpage, it can do pretty much most things are far as sites go and unless you are using whizzy Flash images and animations, it's all you need.
This site (http://www.kamishinryu.com) and this one (http://countrywideexecutivetravel.com/index.htm) were both created using Frontpage and are fully functional in all browsers. The first one uses frames pages, [which admittedly is bit old hat but I don't have the time to change it at present], and the second one just plain pages. Good old HTML is still about the fastest way of loading pages and to be honest keeping sites as simple and straightforward is definitely the way to go. Flashy graphics and gimmics are for the self-indulgent web designers who like to try new things so just stick to simple stuff.
As I said before, if you would like some help then I know Frontpage back to front [no pun intended] and you might also like some assistance with Photoshop to create some very nice graphics which add to the functionality and feel of the site.
Drop me a PM or give me a bell if you wish Danny.
Best regards
Phil

Simon , top class pictures
good to see 3 boats running on the water O0
just built new engine for the chase boat race and have the blue cat all done ::) both engines set up and sound very good 8)
are you planning on a test next week , maybe on saturday morning ;) ;) ;) ;)

Can do sir!
With any luck my new flexi and prop will be here as well.
Cat is re built as well and flying.

Prop saver O0 you can buy them or use an old wheel collet from planes or i use a small zip tie or small bit of silicone tubing slid over the flex.Either one of those methods will save you losing any more props and shafts :o,heck ive used one since day one im surprised no one told you that one >>:-(.
-
Hi Martin
Im not sure what you are on about but it seems like a brill idear. Have you a small drawing??? I take it you put a bit of silicon tubeing over the fleix just after it leaves the cupling. Good thinking . As I can't get out boating today due to the snow and family comming round for dinner I will have a go at that Monday.
HAVE A GOOD EASTER TIME
BILL. O0 O0
-
Hi Bill
Marts right, it's one of those things that you just pick up from somewhere, but forget that not everyone knows it!
You can also use a tight(ish) fitting 'O' ring. It goes on the bit of the flexi inner between the collet and the start of the outer tube. Then, if the flexi comes loose and slides back, it is stopped from going all the way by the O ring/silicon tube.
Sorry it's a bit late!
Danny
-
Yes it is as Danny says put between flex tube and collet ,it was sometihing i was told from day one and it stuck.Plenty of things didnt stick mind but there you go im glad it helped you,pitty it was too late for Simon .You would be surprised how many experienced boaters have forgotten to use a shaft saver and lost expensive modded props they spent a fortune on ::) but it wouldnt be fare to name them {-).

;D
OK, I am a very happy bunny now!
After an abortive Easter weekend where I couldn't get any testing in at all, I finally got a chance to try out the new trim-tabs today, and managed to run a bit more fuel through the engine.
What a difference!!!
I can now give it the full beans down the straight at Kingsbury without any noticeable porpoising or chine-walking and the hull is running much dryer at 3/4 throttle and above too. It is handling a bit more consistently too albeit, as it is going much faster than before, it seems a bit more edgy although I did increase the rudder throw a bit too, which might account for that. Even though I didn't spin out in any of the turns today, [mostly because I was backing off for the corners - not like me at all!], it might need a turn fin but I will try reducing the rudder throw a bit first. [Andy Rennie seemed to think that a fin might be in order but if I can get away with it then I will]. The plug colour is smack on and throttle response just great. Starts easily, runs at tickover speed nicely, pulls out of the hole quickly and goes like a *******!!!
Oh, incidentally, the cooling louvres on the engine covers seem to be working beautifully: the inlet air side were all nice and cool and the outlet air side were quite warm which suggests a good transfer of air taking place in the hull. The only downside might be as Simon suggested that it gets a bit wet inside during racing but as I plan to try out that Bernoulli-induced drainage method, it shouldn't really matter. Danny did you try that method yet? If I recall you were going to.
My water-cooling pipes need swapping around a bit as I have them feeding the manifold first, but the concensus seems to run to the head first, which I will deal with tonight during the post-test stripdown.
Overall though, now really looking forward to Torquay. All I gotta do is find a bigger bag tank - 500ml only lasted about 25 mins at full chat! Any suggestions gratefully received!
O0
Cheers!
Phil
"Who's a happy bunny now then?" ;D ;D ;D ;D ;D

Well done Phil
I use a 1.5 litre tanks. I get bored before it runs out. I think its around 40/50 Min's running time. as I said I get bored 1st. The tank came from Hobby Store. Simon put me on to it and so far it has been very good.
Have a great time in Torquay. Can't stand riding in boats of any size so will not be there. I will however be going to Bristol. If you are comming to Stevenage Please Book in ASAP.
Any one Else out there who wants to come Stevenage on the 4th May PLEASE BOOK IN ASAP. See the OMRA site for details. If you like me cant get in, Nor can I. Send me a mail on this site and I will book you in.Bill
-
Glad to hear you now have her running well any video?,two words though TURN FINS all monos need them to turn well my stepped vee will spin out easy at full chat if im not carefull reason is because i havent fitted any yet ::) have some been made by a mate on a cnc machine along with a few other goodies for my new build see new thread about to be posted ;D.
-
Another productive day today.
I took the bull by the horns after re-routing the cooling pipes yesterday and opening out the water jacket nipples so they are the same bore right the way through.
I have been contemplating how to get an effective self-draining system for a little while and have finally grasped the nettle and drilled yet another hole in my boat! I had a good wander around the net regarding the Bernoulli-induced drain system and have had a pop at it.
I drilled a hole in the transom at 30 degrees adjacent to the trim tabs where there should be an even flow of water at pretty much any speed and then inserted a length of annealed [interior end only] brass pipe through the hole and glassed it in. I'll stick a loop of hose on this into the bilges and silicon it in place. Testing tomorrow to see how it goes! Also made up a turn fin and bracket and fitted that too. It's adjustable for angle and will kick up if I clobber anything. Hopefully it will mean that I can keep my thumb in it on the turns now!
I also beefed up the layup on the port quarter as it was very thin and was flexing enough to have cracked the paint and lacquer. Bilge paint to go over the top of that in due course.
More testing and tweaking tomorrow plus a drainage test.
Cheers
Phil
-
Interesting personally id have done a flush fitting in the bottom of the hull instead,never seen it done that way before hope it works for you.Check this thread out on how to do it ,this thread is by Glenn who also frequents this forum ;).

I went by this article Mart
http://forums.radiocontrolzone.com/showthread.php?t=223704&highlight=Miss+Dumas
In it you can see a number of designs of drains but they all use the same fundamental principle. Proof of the pudding being in the eating I went testing again this afternoon and tried it and the turn fin out.
Both work well.
The turn fin means I can now navigate the Kingsbury bouys at full chat without lifting off or spinning out. In fact I tried to spin it today and couldn't what it will be like when the water is more lumpy is another thing however.
The water drain works too. Not ridiculously fast as some people claim it can be but it works. I chucked a litre of water into the bilges and then threw the boat in and ran it round for a while. Brought it back in and there was just a dribble in the bottom. No more than I would expect. The conclusion is that it must therefore be going somewhere and that must be out of the drain!
Thats testing over for me before the Chase Race. Just one final tweak to make and that is to file a flat on my shaft where the drvie dog set screw bites as it keeps coming undone and I lose drive. I'll thread locker it in place too. Other than that its all ready for Torquay!
Cheers
Phil

Glad everythings gone Ok Phil (and thanks for the webpage advice).
I've put my bailer lower down - on the hull, but as your's is working, who knows, maybe time for a rethink! Drag -v- function!
I've still to test my 'C', so it will have to be between the downpours tomorrow. Course with yeeeaars of experience - should be just a matter of a half a turn on the mixture and off we go ......... as if!!!!
Couple of tips for the chase event -
Startup on the harbour, warm engine up, stop, clamp fuel and wait. Fit prop that will drive boat but allow PERFECT thottling.
Carry minimum equipment into chase boat (possibly spare tranny ???).
On the water - keep going (a chase boat takes TIME to stop, turn round and pick up your boat - don't waste this time).
20 mph constantly for 8 miles is better than 40 mph for 20 seconds, then 2 minute 'break', then 40 mph for 20 seconds!!!
If you're not used to travelling fast in small boats, be prepared for the rush of wind and spray, the watering eyes, the cap blowing off the back of the boat - and all the while 'controlling' the maniac model which wants to disappear over the horizon.
Remember, the course is 4 miles in a straight line - don't spend all your time adjusting a couple of degrees on the rudder - let it run!
Lets have FUN.
Danny
-
Hi Danny
Sounds like my idear of Hell :( Boats are not for me. Have a great day.
Bill.
-
Hey Phil im glad it works for you my thinking behind the flush ones is they dont cause any drag which will slow you down more than you think.Good luck with her first race as Danny says its not all about speed its the finnishing that counts but hey what do i know i dont race {-).
-
Hi Mart
it does work but I think I could have done with a larger bore pipe as the speed at which it empties is not that fast. Having said that, as it's only in the water flow by a mm or so, I don't think it's slowing me down that much. To be honest, I am going for reliability this season and if it proves competitive doing that then I'll stick with it as is. If not then maybe I'llmuck about with it but first lets give it a race!
Danny,
I am really looking forward to the Chase Race and full size boats are very much my thing. In fact in Milford Haven where I sail regularly, and used to keep my own boat, I even used to help run a water taxi service during the holidays, ferrying the grockles across the Haven in big 25' RIBs!
Thanks also for the advice about running the boat. I was planning on warming it up on the hard before jumping into the big boat but good point about clamping off - I hadn't thought of that. I plan to be a bit circumspect as this will be the first time the boat will have been used in anger other than testing so it will be a baptism of fire for it! Lets hope it's not too lumpy and the weather holds fine. The forecast is good by the looks of it....
How did testing with your C go today? I take it you got over to Kingsbury or wherever between the showers?
Cheers
Phil
-
phil sounds like you are ready :D :D :D :D :D
one question , why do you want to clamp it off ?
tony
-
Well Tony hopefully clamping it off it won't make my eyes water too much! :P
I was merely going by Danny's sage advice. Presumably clamping it off ensures the fuel pressure in the carb stays constant and ready to go at a swift pull of the starter cord rather than having to pull fuel back into the carb but I dunno! I am just bowing to the advice of those with more experience of these things than me! As long as I have a bit of fun and manage to keep my bum relatively dry, I'll be happy!
See you a week tomorrow Tony!! :D
Cheers
Phil

Here I go Agian :( :(
Been out today and the tail end of the Ex pipe has now broke off :( :( :(
What do I do to fix this prob???? I have, and would like to use a MHZ pipe but I am very worried its going to pull the head apart??
ANY IDEARS WELCOME

Wow thats a looong header what tuned length do you have from flange to wides part of your pipe?,where is the break i dont see it ?.
Mart
-
Hi Mart
The break was at the tail end of the tuned pipe where it comes out the back of the boat. I am now thinking that I will have to bite the bullet and get a complete new set up from Bluefishy. I am peed of with it now as I have run out of ideas what to do next. I have spoken to Tony this morn and he is going to have a look though his old stuff to see if has any thing to fit the bill.

Bill,
You could always get one like mine. Have had no problems at all with the exhaust, the only bit i havn't.
Phil is also running one?

Not working?

Here you go Mart
1 broken tail pipe pic
-
never seen one break there before how is yours held maybe you need more flexability to stop any undue stress due to vibration?,you never saifd how long you had the tuned length set at?.Your header looks way long that why i ask,id say its no way near its optimum length unless the picture is decieving?.you can get some decent pipes on the net for a good price but you will have to wait a week ::).if you can wait that long and you cant get one local try these places

Thats bad news Bill. :(
Simon is right. I am also running one of Andy Payne's designed pipes and I have to say its beautifully made. Nice and quiet and seems to produce plenty of oomph. Together with the integral header and water-cooled manifold it was around £145. I know it's not the cheapest out there, but then you get what you pay for I guess.... Seems like money well spent to me.
Incidentally, I have just acquired some 2litre bag tanks and I will be testing one out this coming weekend. They are brand new re-usable urostomy bags [nice!] and seem to be completely petrol proof and so does the integral 90cm big bore pipe that comes with them. They are 2-port with a shut-off valve at one end. Not sure about using the valve as it may get knocked shut when racing with the associated lack of go that would come with that eventuality! I am sceptical if they are going to be robust enough and hopefully I have some IV bags on the way too so it will be the pick of the bunch that wins out. If I have any left over and anyone is interested, then let me know when you see me next weekend.
Hope you get something sorted out Bill.
Cheers
Phil

bill have a look in the parts bin but i dont have a spare complete set up , plenty of bits :( :( :(
i would go for either a sikk 2 " band from barry or go for the ebay pipe that mart has put up , i have one of these for the cat and for the money they are very good , or go for one of andys as he will make it for you if you need some thing a little differant 8) 8)
can you book me in for the race please
D20 , 2.4 gig,, pace/ zenoah
many thanks tony O0
-
Thanks for looking Tony. Have booked you in for the 4th May.
Been in contact with Tony Stoddard and he has come up with the bits useing as he dose my MHZ pipe. I have fitted a big pipe clamp round the Ex pipe which now means no weight at all on the header pipe or tail end. I am going to get a new manifold. shepherd hook S/S pipe, and a w/cooled cuppling. Fingers crossed. Bristol is but 2 weeks on Sunday. :-\ :-\
-
Sorry to hear about your pipe, again, Bill.
I think it's a vibration problem, rather than a materials issue. The pipes are quite a size and even with the smallest 21 size, I've always used some bracket to support the main section of the pipe, not just the front and back. It's preferable to have a rubber mount especiaslly with noisier engines. The header, if bolted solidly at the engine, needs to be a loose fit into the pipe to allow vibration to dissipate at the joint rather than be transmitted to the pipe. The stinger can either be connected to the transom outlet by a flexiible pipe or, if space is tight, the end of the pipe can go through the transom but is supported by silicone tube between the pipe and the transom (tight hole).
I've been lazy this time and just made a straight support bracket, but it quitens down when the boat is in the water.
The pics might help show the idea.
BTW Phil, I forgot that your carbs are higher than our rear induction nitro ones so you don't really need a clamp! Although your reasoning for having one (preventing back syphoning) sounds so good that I will 'steal' your theory and pretend that is what I meant all along (- you're never to old to learn ...).
Bring the "Quells" on Sunday {-) :D
Danny
Edit - spent so long typing it - you've got the answer yourself O0
-
Thanks Danny.
Don't worry about the sea sick pills, Im not going as i get very sick at sea. :-X :'( :embarrassed:
Cheers. Bill

WHERE IS EVERYBODY????
All getting there boats ready for Sunday I bet.
May the best man win! O0
-
im here bill :) :) :) :) :) :)
got the boat ready , car packed , ready for the of
any one have a good carb setting for a zenoah running in the SNOW :D :D :D :D :D
tony

Hey Bill found a new muffler for you O0
-
Hello
Well 4th time Lucy. New header, manefold pipe, brackets fitted on the MHZ pipe to hold it down ,but still enough to move a bit. Fingers crossed for it run out on Sunday in the SNOW. I'm still going, blow it {-)
-
Thats the spirit ill be thinking of you whlie im having a lay in with the missus {-),i take it you didnt like my CAN muffler {-) actually that was made by a friend and apparently its quieter than the bought ones due to its size,simple to make too just a little bit of jb weld to hold the exit tube in place then some high temp silicon to attach to the pipe.Hes just finnished an even better one,only adds 1" to the pipe so will fit inside the hull too,the cans are two 33 cl energy drinks cans heres a cpl pics of his lates one.
-
I needed im idear last weekend like an old Coke can. Still Got it fixed up now. Hopfully it will be ok.
-
Good luck with it ,ill keep you posted on how this muffler works out .
-
Well How did Torbay Go. Much snow? Lumpy sea? Who came 1st 2nd 3rd in the D class. :)
-
Bill,
Great fun, must be absolutely mad to go boating in the snow and wind!
The original course was changed as apparently there was a 6 foot swell on the other side of the bay. So we skirted the coast and went around an island/rock.
Very windy and rough. But great fun.
Cant remember who one the main points as it was snowing when the trophies were handed out.
Phil did really well with his Makara in his first race!
Next race for us is Telford.
BW
Simon
:o
-
Hello. Dose any one have the results of the D class event at Torbay yesterday??
-
Hi Bill
Not sure on the 2nd and 3rd placings but Phil Hatcher took 1st I think. ::)
The weather was a bit on and off for most of the day with a fresh NW wind blowing 5 to 7. As Simon said the course had to be changed as there was a 3ft chop over at the Brixham bouy, or at least there was when I went out pitting for Danny on the first set of 4 runners. I think only one person managed to finish on that original course and that was Andy Rennie and he took over an hour!!! :o
Once the course was changed things got much better and I had a very enjoyable run, mostly due to the superb pace notes I had from Tony Gilder who pitted for me. Thanks againTony! O0
Stevenage next for me I think. Better get my entry form in!
Cheers
Phil
-
phil
i think that mr hatcher took 3rd and jeff stint got the win , but i may be wrong ,as i remember it was snowing at the time and tony e was hiding out the way :D :D :D :D :D
very good day and glade you had a good run , told you you will injoy it O0 O0 O0 O0
pitty i had a problem >>:-( >>:-( >>:-( >>:-(but the new boat was good while it lasted :'( :'( :'( :'(
still thats racing {-) {-) {-) {-)
tony
ps bits in the post to you O0 O0
-
Ah! in all the excitement I may have got it wrong Tony! The cold had probably addled my brain by then! :D
Looking forward to seeing what you have posted to me!!! 8) I like surprises!!!! O0 O0 O0
Cheers
Phil

congrats on your first race Phil ,Tony what hapopened to youres mate? is this the one with the sg motor or another?.Oh and cheers for the header mines in the post or will be this afternoon.
Mart
-
Phil,
Sorted out the problem with the fuel today, had the rest of the week off and went down to Brentwood to flush all the salt out. Had to be done.
Anyway loads more air in the lines and kept cutting out, turns out the pipe with the clunk had fallen off inside the tank and i was only getting fuel supply to 3/4 full.
Good job it was a short race on Sunday and i topped the tank.
Another problem ironed out!
Spent the rest of the day tuning her and getting the strut angle sorted, speed today, in the wind and ripples 40.7 mph.
Going to try out my NOS kit on Damons boat and see what difference it makes and may use on mine?
if you have not already sent the IV bag don't worry, will catch up with you at the next race, Telford for me?
Regards
Simon
:D
-
Nos ? {-) waste of time in a boat,if it worked everyone would be using it :o.for starters you will blow the motor in seconds and to see any real benefit youd have to use a good size bottle of nos for it to be effective in a boat id say ,also i think im right in saying that when using nos the motor also needs more fuel to burn otherwise the piston will fry !!!its been tried over in the states and in my opinion id stay well away unless you want your zen to go up in smoke.Far better to get your motor modded for a long term increase in speed rather than 4-5 seconds and then bang!!.
-
mart
your bits in the post O0
i was running the new hull with a zenoah in it , have another almost ready to go with the sg , them will swap out the single zenoah for the inline twin set up , then i will start on the big cat {-) {-) {-)
tony
-
Dito mate sent em recorded post after the other fiasco >>:-(,that sg is gonna eat up those little zenoahs {-) even with a boat full of nos ;).What cat are you building now?,my mate Wayne is well happy with Simons cast off :o.Will you be racing the cat in omra now that would be cool,give those makaras a lesson too i reckon ;D.
Mart
-
Mart , i have 2 cats to build one i will not be running in any race but i have a falcon that i may use but only a play boat , and a set up boat for the engine tests
tony
-
Come on Tony isnt it about time those omra boys saw what speed was {-) only joking fellas ,those falcons are quick not the best in rough water though but theres plenty of cats that are as you know.One day ill build a big cat for twins but ill settle for the hydro for now,its gonna be a head turner once ive done as this ones a labour of love ;).The motor i have was modded by redline in the states after orriginally been a warehouse hobbies motor its a full mod so should be a beast.
Mart
-
Simon,
Glad to hear you managed to sort out your fuel probs. I have popped 2 bags in the post to you so you can have a play around with them.
I had an issue with my throttle control on Sunday when i tried to start the boat in the RIB. when it started it revved its nuts off for some reason. Following the full strip down after the event, it turns out the engine mounts were not as tight as they should have been and the engine moved a bit changing the throttle settings. Fixed now!
I was supposed to be working on Sunday but my gig has blown out so I am on for Bristol now! Anyone going?
Cheers,
Phil
-
Sorry about the double post there!
Cheers,
Phil
-
hi Phil thats why i allways use cables for the throttle no vibratiuon issues either.
Mart
-
Hi All
Yes I'm going to Bristol with Ian. Lets hope it stays fine. + my boat holds together for the race duration O0 O0
-
I had a nightmare testing session today :(
Nipped over to Kinsgbury for a quick half hour just to set the needles and strut angle. Everything was going fine - lap after lap with no probs - running a little wet but in view of the forecast being windy at Bristol for the weekend, a little down-angle on the strut would be a good thing.
So, back in to check the plug colour and make sure the needles were set okay and then back out for a few more laps. The all of a sudden the thing starts losing power so I bring it back towards me in slow circles blipping the throttle to keep it going and slowly and had it pointing more or less towards shore a few yards out ready to hit the kill switch. I missed.... and in fumbling for the switch and the rudder, drove it up the bl**dy bank. >:-( Turns out the sparkplug had come loose. :S
Big ding in the GRP on the bow, a few scrawps along the underside, turn skeg scrawped and the prop looking a little dishevelled. Looks like I will be burning the midnight oil tonight in the garage.....
Pfffffffffff!
Nothing so bad that it will stop me from being there on Sunday though, so I'll see you there Bill!
Cheers!
Phil

Hi Phil
Oh Bug*** . I had a very quick run down the lake yesterday. My Ex pipe probs seem to be shorted for the time being so I got my boat out of the water before anything eles had a chance to go wronge. I am looking forwards to Good day what ever happens. O0
-
Sorry to hear that Phil but how the hell did the plug come loose :o,also whats with a kill switch? just set the trim on the throttle to kill the motor,kill switches have a bad habit of swithcing the motor off when you least want them to especially if they get wet .
MART

Look who's got on page 76 of Model boats mag. One of them Mad Makara Men. O0

Dont read it its full of slow scale boats :D.
Mart

Well here is the extent of the damage after being run over on Sunday at Bristol. :'( Another boat managed to slice into the starboard stern quarter with it's rudder or turn fin and also rip a couple of big chunks off the lid on it's route over the top.
It looks worse than it is I think but still not sure if I can salvage it completely. I'll know once I start chucking the P40 about. Luckily I managed to retain most of the bits so forming the right profile might be made a bit easier by piecing them back together.
It's quite clear from the extent of this damage that the hull strength isn't that great and I have had to beef up some of the layup before now as it was flexing so much the paint was cracking! :o
I think a layer of matting inside the entire hull wouldn't go amiss!
Incidentally, do they do Makara hulls in ferro-cement!?? :D
Cheers
Phil
-
Hi Phil
Give Paul f a call he may be able to give you some clues what to do with your boat. I would go for a thin ply build up from the inside and them fill it out.
Hope you get it shorted for Stevenage.
Heres a pic of Ian's Ex CMB after Sunday.
-
Poor old Ian did NOT have a good day at Bristol! His 21 also graunched a rod.
Hard luck mate
Danny

Thanks Danny, for those kind words.
Bill,
Nice piccy. I told you I wanted the good side for eBay though.
One careful owner. Unfortunately it was Syd.
-
Well, after a week fighting off some 'orrible chest infection, I have finally braved the cold and nipped up into the loft to start repairs after last week's shunt at Bristol.
Fortunately, I managed to recover most of the bits that got knocked off during the impact and after cleaning these up, I Slo-zapped them together to get the overall shape back again. Where the rudder of the other boat went through the side of mine, it left a nasty overlapping bit of grp so I ground that away so the two edges would meet back up again then glassed behind it and filled over the join.
Some judicious use of P38 and P40 have given me back the overall shape and I have just blown a quick coat of paint over it to see what minor imperfections need filling and sanding out.
To beef up the hatch closure, I have let in a piece of ally flat bar which will be drilled and fitted with the cowl locks.
Other than losing a couple of my decals [sadly they were nice ones!], overall, I think I have managed to salvage this hull. Looks like I will be there for Stevenage all in one piece!

Well Done Sir. :)

Looking good Phil.
Are you running at Telford?
We had a little play yesterday, windy and rough.
Still got some radio glitching problems, managaed to spin it out in a bend and the lid flew off breaking the clip.
All fixed know though.

is there any ink left in the printer :D :D :D :D :D
phil , your repairs look good well done . did you fit the secret thingy i sent you ??????
the chase boat ace was good and your boat did look very good on the water , as did your simon , i told you both that you will only use a very small amount of throttle !!!!!!!
heres my 10p worth , the makara hull shape is a well provern design ,what has let it down for a lot of people is the build quality of the hull the sigma is built very differently and is build in a very differant way
on a performance level both hulls are very differant and have strong points and not so strong points , a simga in this years chase boat would have been a no no , but the makara a yes yes . however at kingsbury and burton yes yes to the sigma
i can put the coments forward having both hulls and raced them

Simon.
Can you text me the result of the D class 1st,2nd,3rd next Sunday from Telford. I am away and would like to know how you and others got on.
Cheers for now.
Mad Makara Bill.

***Moderated***
Phil, great repair - I'll bring mine round tomorrow ;-) now I've got the bits of wall out of it. I've started the repair but I'm afraid I don't have the patience to make it look good (no concours for me, then) ::)
Who's at Telford next Sunday?
Watch the weather forecast - if the wind is from the South or South East, the end we race at will be fairly calm. If its from the North East then the end could be quite choppy. I hear the club has also had new toilets built AND have proper trophies!!
Nice big course so a chance to really put your thumb down (or up?)
Danny
PS If you haven't already noticed, the OMRA site is down as the host company are changing the "thingy". When it comes back, it will be the new design which this time, I hope all will be able to see properly.
-
Hi Danny
I had noticed the omra site was down. Looking forwards to seeing it back on line and being able to use the site. Keep up the hard work. give yourself a pat on the back for having a dam goood try.

I fully agree with Tony O0. Prehaps when ordering a Makara ask if they will mould one with extra lay up to give extra strenght. Dont forget it does not matter whos, or what hull it is, if it is made of polyester resin then it will suffer damage on impact :'( . If your boat is a "sitting duck" and somebody hits you at speed there arnt many boats that get away scott free. Ive see epoxy boats split, more so at the joints.
Ive been an OMRA member for many years after doing muti racing, look at the price of there hulls now.
Yes, you manly do get what you pay for but take a leaf out of Bernard Holders book, all his own boats are made in poly and he still wins . its the old story, one boat for the choppy conditions and another for the calm. ( they dont race muti in the rough sea )
Dont forget ,no two boats are the same.
Keep up the good work on the repairs Phill, looks perfect to me.
Gary.

It's Sunday 11th May and yes, Richard, I'll definitely be there (I don't mind you jeering but don't bring that megaphone)!

Better be there on the 11th then with the megaphone. See if we can get you above 6th position {-)
-
Looks like a calm race then? WSW 9mph (Saturday anyway?) Might even bring my little AA as long as you promise not to run over me.
The Makaras will handle the weather rough or calm, but rougher is better
See you Sunday

Are you not racing Sunday?
A very quick dunk on Sat just to test teh aeriel mods and then back to base for a polish.

Simon

Regrettably not Simon. I am teaching up in Runcorn on Sunday so no mucking about with boats for me. But I do hope to have mine back in one piece by Saturday so if Danny wanders over to Kingsbury, I may give it a bit of a wet and see if I can set it up a bit for Stevenage.
Hope the 'leccy bits behave themselves and you have a good run.
Cheers

Hello one and all
I am going to Weymouth OMRA meet. Dose anyone have any B&B details that they reccomend to stay on the Sat night.
If you have can you drop me an e mail unicornsound@hotmail.com
Ta very much
Bill :)
-
Hi Bill
Thanks for the pat!!
Mrs 85 and I usually stay at the Travellodge in Weymouth, which is next to the campsite. It is reasonably secure as quite a few modellers stay there. There is enough parking for all rooms which is something to look for especially with some of the seafront guest houses (of which there are loads). If you're only staying the one night, most B&B's don't want to take your booking until the last minute in case they get someone for the week (changeover is usually on Saturday).
This year, just for a change, we're trying out
http://www.harbourlights-weymouth.co.uk/ (http://www.harbourlights-weymouth.co.uk/)
which, although it hasn't got a bar, has good prices and they sound like nice people. Anyway, if you go to the "entertainment" at the Pavilion, that's Sat evening taken care of. There are stacks of bars and nice pubs round the harbour for evening drinkies.
Are you staying Fri and Sat night? If you do, you can go to the trade show on Sat, spend a few bob then watch the Z class on Sat afternoon.
If you need any more info, give me a shout.

Thank you very much for coming over to Stevenage OMRA meeting today.
I hope you all had a good day without to many breakdowns.
Looks like the new paint job is working for you Simon.
Cheers Chaps
Do it agian next year??? That bit is down to all of you. O0 O0 O0 O0 O0 O0
-
Thanks Bill, great job, well done. The two heats makes all the difference.
Ran the engine up when i got home and the throttle servo jammed, how about that for luck?
Third and Concourse, very happy with that. First proper race this year so a good test bed. The water/weight helped in the 2nd heat.
Shame your rescue crew to a chunk out of one of my chines? Still they do the best they can.
Big thanks to all the guys especially Big Tee for a superb pit man and his tuned engines [/16] made all the difference when needed. Nice to have all that power when needed.

A great days racing yesterday Bill. Thanks to you and Ian for organising such an enjoyable day which was well run and well organised. Two heats was great! The boat behaved itself well and I was even leading from the start for a few laps and even overtook Gary at one point in the second heat! Only one repair to make this week and that is to a servo horn so I got away relatively unscathed! Many thanks to Damon for pitting for me.
Congrats also to Simon for getting a very creditable third [your 5 championship points ahead of me now!] and for the concours but then that is a foregone conclusion!!! :P
Superb result for Tony with a very steady and consistent race and a massive number of laps overall! [Nothing less than inspirational Tone!]
Looking forward to getting the boat a bit salty next weekend at Southampton. See you there!
Cheers Phil.
-
Thanks to Ian, Bill and Greg (+ all the helpers) for a good days event. So many heats, I didn't know which one I was in ::)
Hope I didn't damage the wall too much - I really must find another way to stop!!
Well done Tony and Mr Concours O0

Hi Danny
Good News!! The wall is just fine ;D
Can't make Southampton next week but good luck to you all.
It seems a long time to Kingsbury meet. Is there any other boating going during to break? Seems a long time to wait.
-
OK. I give up ! where is everyone ::) ::) ::) ::) :(
-
Hi Bill
Had a visit to Kingsbury today for a quick bit of testing. They'll be better next week in the races - or else!!
I'm going to pop over the see the fine selection of hangovers at Wicksteed tomorrow. Won't be able to join in though as I'll be driving.
I thought you were going to do a demo run for them? Don't tell me they didn't want a fast noisy thing running into the wall? Oh, that's me, isn't it {-) Well, I'm not takng a boat tomorrow so they'll just have to make do with my good looks ::) ::) {-)
Danny

Hi Danny
Went up to Wicksteed yesterday, which was just as well as I'm not sure how many turn out in the rain. There was some Brill lifeboats on show. It's made me think about having a go at building one. Just got to find some spare cash now.
Going to pop down our lake now to see if any one Else wants to stand in the rain boating.
Cheers for now

Hi Simon.
Ok I will put it up for sale on the OMRA site. Yes it is one of Martin photos. Can you let him know. I have ask him a long time ago if it was OK to use.
