Title: TAMAR Speedline 1/12
Post by: ovl on June 24, 2015, 08:21:40 am
Hello everyone,


Just arrived on this wonderful forum,


I 'm going to start the build of the TAMAR from speedline models. I hope to reach the level of some members who build the same boat  :o


really amazing what they achieved  :-))


I hope to find some help on the forum.

Welcome ovl.


Are you going to do a build thread?  It can be quite helpful in your build, plus we all love pictures. :-))

Dont forget that I can help too!  :-))
I will be watching with great interest since so much has been changed and we now have new instructions.
I am going to Cromer in a week or so to see what the current boat looks like (changes etc) and I want to make one of those ledder thingies that gets thrown over the side to help survivors get aboard, Jacobs ladder or something I think.
I am also off to see my new girlfriend Patsy Knight on the same day. Anybody know her?

hi Unsinkable,


Yep, it's a very nice beer  :D


where are you in France?

thanks for the comments on the boats,


It will take some time to restore the other boats,

Im about 30 mins from Saint Nazaire, that's the closest big place and I live right on the coast. I pass the shipyard every day on the way to work. I used to live in Holland near Breda..... I get around a bit :} I fancy a trip to Bruges with my OH someday, it looks really nice.     U2

@ Unsinkable: 
Ok let me know  :-))


Even if I didn't start my Tamar yet, I have questions already,


On the next pictures : (I think it's called waterscooper)
The are not part of the kit, but I would like to install some for water cooling of the motors, then link the tubes to the exhaust.
Does anyone know where I can buy them?
Do I need to install a water pump also?


Thank you in advance for the info.

I did think about doing the water inlets as a casting when I first did the Tamar but decided against it for some reason. I would do them now.

I ran mine on two Emax BL4030 motors using the five bladed scimitar 55mm props supplied and it was very fast and gave good running time on a couple of 4000mAh 4 cell lipos. I recommend this set up because I know it works well but there will no doubt be better arrangements now.

The speed controllers were not cooled either and everything performed very well.

Hi ovl
Prop shop in the UK, you can't beat their couplings, Especially for brushless motors, I have them in my lifeboat.

Title: Re: TAMAR Speedline 1/12
Post by: Flundle (Speedline Models) on July 12, 2015, 09:14:54 pm
I think they are Emax BL4030's (just to clarify).
Have a word with John Wright at Jotika. We have discussed this and I think he can do just the couplings you are looking for. Its two aluminium parts each bonded to a length of rubber and they provide very good results and are silent in operation.

Hi everybody,


Had a response from prop-shop.uk (the only who responded to my request)

Hello,


I've started the build (finally) ;)


First problem.


according to plan I have to Attach a Brass tubing 10mm onto the hockey stick and keel, NO 10mm brass tubing to be found in the parts  >:-o
The biggest I found is 8mm, can anyone tell me if that's ok to use please?

just a question,
I still want to build those water inlets (see picture earlier on this post) on my tamar
Does anyone has the right mesures for them or a plan whit mesures?


Thank you in advance  :-)

Hello everybody,


long time since I gave some news, but too much work, so no time to start the Tamar.
But...


I asked some info concerning those water inlets, but no answers, so... I send the pictures to 2 friends of mine in France and those guys did a wonderful job  O0 O0
Only based on the pictures I have !!!


They used 3D program Rhino and here we go
[size=78%](http://i18.servimg.com/u/f18/18/92/82/79/15081210.jpg) (http://www.servimg.com/view/18928279/89)[/size]


from there they made à prototype in plastic

Amazing result he  %%


then casting , they used Surgical Steel Chrome Cobalt, so It doesn't rust  ;)

I could even chose the finish, I choose the polished chrome , I know the real one isn't finished like this, but I think it looks great !!!!

I notice the couplings you have chosen, these are the same as I originally fitted to my Speedline 1/12 Seven. Very expensive. In spite of all the best alignment they are too noisy and I changed them to flexible joints as others have done. In view of the hi torque from the motors I filed flats on the shafts and removed the screws from the couplings and fitted small Alan screws where there was a better facility to tighten to avoid spinning on the shafts. I know these couplings were very expensive but throw them and fit flexible joints. I never had and problem with vibration, spinning, removal for service etc and they ran very quiet.

Post by: kinmel on June 09, 2017, 08:07:33 pm
Thanks Kimmel.


What about the minimum torque?

I had no problem at all with rudder steering, I simply picked a pair of metal geared servos from HobbyKing and had no problems.

The planing characteristics of the hull makes the model very responsive and the servos don't have to work hard at whatever speed, especially with twin props on "tank steering"

(https://i11.servimg.com/u/f11/18/92/82/79/img_1216.jpg) (https://servimg.com/view/18928279/205)


made a platform for the receiver, sound module etc (in the middle under plexiglass) and the batteries on the outsides
(https://i11.servimg.com/u/f11/18/92/82/79/img_1322.jpg) (https://servimg.com/view/18928279/204)


Fixed the platforms, the axles in the hull with epoxy, also the motorsupports are fixed to the platform with epoxy. Here's a picture how it looks (without the plexiglass in the middle) and with the lips buzzers connected to the batteries.

This is part of the fun with Speedline models, some of us appreciate these challenges  :-))

Watch a few Youtube videos of Tamar launches, most have good shots of the transom and by drawing lines from known points, you can place items with great accuracy. 

You will have the same problem siting the anchor point for the launch release catch. The components for that aren't even listed, never mind shown on the drawing.

Keep going.

OVL,
Not sure where I got them from [people quite often give me sets of lifeboat plans at Shows] but here are a couple of shots from two 'part' sheets I have of the Tamar, but they appear to be at 1/12th scale, enlarged from the markings on the plans that they are at 1/25th scale. I am not going to be building a Tamar, so hence no complete set. However, seeing as the RNLI do not appear to be supplying plans at the moment I have photographed these two areas to help you get on your way with your model. I have also added two photos from my collection, they might also help position those nice shaped water cooled exhausts [and covers].
Cheers,
Kim [C.C.]

Hi Ovl,
I've just measured off my RNLI plans which are at 1/25.  The inside edge of the flange around the exhaust is 4.8mm (@1/25) and the top of the flange is 2.35 (ish)mm (@ 1/25) under the Y boat storage recess.  Hopefully together with the photos from others will point you the right way.

quality is not very good I have to say

that's what building is all about...........bit of cajoling, bit of strengthening, bit of filling and rubbing down.....vac formed tubes, as are grp tubes in two halves are notorious for fitting together......just look at the wreck of a 21 I've been working on..........loads of inner supports, and still needed filler...........the joining of two pieces of thin vac formed abs edge to edge is virtually impossible without filler.........just the nature and complexity of the models we crave for these days, putting the manufacturers under so much pressure to come up with the goods in small cottage workshops.

I don't think its a small contribution, ovl...........the amount of people who are complaining about the refusal to sell plans at the moment is probably costing them hundreds of pounds a year, and this has been going on for nearly 3 years without any thought of re introducing the service...........and to be honest, lifeboat modellers with all their little shows raise thousands per year for the charity.

Hello all,


just back from a test on the water !!
problems with rudders, I don't know if my servo is strong enough, was not able to steer correctly!
So I' could not go full throttle, but it was nice to see her on the water.


Can somebody tell me what servo to buy? (how much KG's it must be able to pull?)

is that a "mini" servo, chris..........if so, you might want to go for the normal sized servo with metal gearing as opposed to plastic gears......its a big lump to steer on a mini job.

Post by: CJ1 on April 25, 2018, 01:11:10 pm
One thing I noticed on your earlier photo of your servo/rudder set up, the linkages look like fairly thin brass wire just bent into the servo and tiller arms. If you had tubes or rods with proprietary adjustable linkages either end, there would be less play and less chance of the wire bending under load, and that would definitely give a more positive response. It's not expensive and for sure worth it for a large, heavy boat like this.
The photo is of my 1/12 Speedline Tamar, and as I say, still no problems after 5 years running.

Hello Olav ..

I am also about to start building my Tamar soon .. looking for suggestions and tips I have come to your side .. the water inlets you have installed are really awesome .. !! WOW ..
I would very much like to grow them and use them with the water which flows in there to cool the two regulators ..

That's why I want to ask you if your two friends from France can also do two of the water inlets for me .. ?? I would be infinitely grateful to you and your two friends ..

Post by: Flundle (Speedline Models) on October 12, 2018, 01:40:40 pm
Looking at the installation I would think the throw on the servos is too small giving you very little turn on the rudder. Make the throws as big as yo can and retest. Qdjust as necessary at the lakeside.
The servo you are using is fine for the job (dont forget that the rudders are servo assisted by their shape).
The above comment regarding the stiffness of the push rod is very valid. Sliding the push rod through some close fitting carbon tube should help a lot.
Good to see someone building a Tamar on line.
I change the mould for the wheelhouse some time ago to improve the fit of the bridge assy to the GRP wheelhouse. One thing I did as a result was to remove the front face of the bridge moulding and replaced it with a 2mm thick laser-cut part.
A recent customer tells me that its missing and it does look like yours truly has not made one. Tony, (the GRP man) is making me a section of the wheelhouse across the bridge are so I will make the missing part and it will be in future kits. Its easy to make should should you be missing one but ill send you one if want.

It was good to see the Tamar on the water but It needs more power than you can get from these 800's. They will get very hot too.
My advice is to change them for emax BL4030's and run them on four lipos cells each.
Not only will it go much better, right up on the plane, but it will run for longer too.
The current motor mounts look great and they will mount the 4030's very well.

Hi Holger. It would appear that that particular series of motors are discontinued. I found this page that attempts to provide equivalents but they may not be exact

Hoi Tamaris ..

thank you first for your help ..

The PO-5065-360 would be good because I still have 6s lipos and I could continue to use them .. but the motor shaft has a diameter of 8mm and there I find no matching clutches ..

The Turnigy Aerodrive SK3 - 4250-410KV has a little more turns and the shaft diameter of 5mm is suitable for me because I still have matching couplings. However, I would need for him new batteries ..

but the more I think about it I'll probably decide for the Turnigy. .hab still a little time until I need it ..

as a controller, I have chosen this one here. .I think he fits very well ..

sorry but  that seems ridiculously well  over the scale speed !
That was a testing session in the worst conditions I’ve had the opportunity to make use of .
I discovered that strong wind seriously affects steering due to the bow being almost completely out of the water. I proved it won’t blow 25 amp fuses at continuous full speed
She’ll turn hard with no instability and is now completely reliable.
My silicon seal for the deck limits water ingress and bilge pump sorts the rest.
I need a smaller body if water with same wind for tougher waves
At more sedate speeds and manoeuvring I can get nearer 45mins running

Hi
Now I have both controllers - Turnigy Marine ESC 90A - programmed and if I plug them individually at the receiver you run .. because I want to run both motors s.einer receiver channel I have heaped on a regulator + cable and with a Y-cable with connected to the receiver .. now but only the engine runs with the three cables and where I pulled out the + cable beeps only as not yet programmed ..

what is not working .. ??

how did you connect the regulators .. ??
Title: Re: TAMAR Speedline 1/12
Post by: Taranis on April 22, 2019, 08:01:06 am
With mine I think throttle has to be at full when transmitter is turned on before switching on receiver
Then I get confirmation beeps from both ESC at which point pull throttle back to null.


Is it a plain Y cable ? Not one with servo reverser on one leg
Title: Re: TAMAR Speedline 1/12
Post by: Holger on April 22, 2019, 11:14:05 am
yes Andy .. it's a simple Y-cable ..

I have also inquired on Facebook and as one uses the same controller without a red cable to remove and it works perfectly with him ..

So I would only once again see if both motors individually again run and if so both then connect with the Y-cable and hope then both run as planned ..
Title: Re: TAMAR Speedline 1/12
Post by: JimG on April 22, 2019, 12:49:15 pm
Are you sure that the receiver is powered up? An esc which is not receiving a signal will beep to let you know this. Make sure the receiver is powered up first before connecting power to the esc.

Hi Holger,




Sorry for the very late response, but I was out of modelling for over a year (opened a restaurant and had no time for anything else.

hoi Olav ..

First of all, thank you for your answer .. !!  :-)

unfortunately it came a little late because I have already installed the motors .. but maybe I will remove them again and use the bracket that you used ..

I had to look for something because of the side of the motor mounts that you sent me, but I found it .. you had a small typo.

mini-meca-rc.com ..

I also had almost no time to continue building the Tamat ..

Only a disease followed by an operation in the hospital .. after the recovery, I was fully involved in my job .. but now it has calmed down again and I can finally devote myself to my hobby again .. !!!!!!

so i used the time of recovery for research about the model .. i came across these two pages ..

https://my.matterport.com/show/?m=n8zEKKbKMaG

https://matterport.com/de/media/2518

YOU ARE THE HAMMER .. !!!!!!!!!!!!!!   :-)) :-)) :-)) :-)) :-)) :-)) :-))

see for yourself .. !!!!!!

  and I noticed some differences between the kit and the original .. for example the four flaps above the Y-boat are arranged in a slight curve to each other and so adapt to the bow-shaped deck .. also the two inner flaps are narrower than the two outer plates ..

so now i am changing this and some other parts ..

I wish you and your family a Merry Christmas ..  :-)
