Title: RTR Boats
Post by: Stavros on September 16, 2007, 03:00:05 pm
Right me being me decided with a sudden rush of blood to my gob,decided to buy a Speedy boat in Nautilus shop in Albert Dock Liverpool,well I thought to myself it got to be good cos it says MAYHEM on the box!!!!!!!!!
So I bought one,it is basically a Bat Boat,came with it was a charger,1800mah batt,controller,boat stand and a very good transfer sheet,inside was 2 x 380 motors and a speedcontroller/mixer and a spare pair of props.Now me being me initially thought well swap the motors for some speed 500's 2x esc a mixer and receiver as it looked a good hull.How wrong was I charged batts over night and took an extra 2 with me thinking the blurb was a load of pooh pooh,ins said at least 30 Min's from full charge ho did I laugh and HOW WRONG WAS I very wrong on all accounts.Last night whilst putting areal on tranny it would not fit so off came the holding screws and realign the nut which holds the areal and whilst rear of tranny off lets have a good look and law and behold there was a 40 meg crystal soldered to the circuit board wow a proper set!!!!!
Now on the lake this morning it was launched Whit the 7.2v pack throttle was sapplied and off it went oh and boy did it go,now as many of you know RTR 's have a notorious range NOT THIS ONE well over 200yds away it was still going strong with FULL control,so back it came at full chat after 10Min's flat out running it was bought in ho check how hot motors were they were blooming well cold!!! and it was bone dry insideThe 1800 mah batt kept going flat out for over 30Min's with various guys from our club trying it out.Me being em a speed freak decided oh how would it go on 8.2 or even 9.6 volts so 2 packs were borrowed from Robert Davies,first the 8.2 pack was tried well the difference was good when the 9.6v pack was used well all hell broke loose boy oh boy does it shift,and what amazed us all after 15Min's running I bought it in and OK the motors were warm but not excessively so now others in the club have got to have them!!!!
I would highly reccomend this boat to anyone wanting some speed in their lives especially with 9.2v one thing I would personally do is to disconnect the wires that are connected to the shafts for the simple reason that on full power turns it cuts out slightly this is because one shaft is out of the water and electrical contact is lost as it relies on water to make a circuit apart from that buy one and enjoy O0 O0 O0 O0 O0

Not that bad gets some speed up but she is too heavy to really get going i think.
Better off with a set of 400 race motors then she would fly along nicely O0

If it is on 7.2 v why not do as I did and try 9v it should fly

Post by: J.beazley on September 16, 2007, 09:55:57 pm
I use a 2100mah 8.4v in the standard bat boat and use a 7.2v 1800mah in the upgraded boat.

Dont tend to use my fast electrics these days as they usually upset people if the lake is busy, only use them if the lake is empty that way i dont destroy others models.

Thinking about it a few of us on here have these so why not get a MAYHEM TEAM going in the fast electric racing stakes  O0 O0(just a thought)

Hi.. Im a newbie here so hope you dont mind my comments :-\

Ive had a couple of the EP speed boats that you refer to, they are fast & fun for what is a cheapish RTR boat!

I recently got this RTR boat from Howes

http://www.howesmodels.co.uk/RadioControl/viewProduct.php?ProdID=1832

for a ridiculous price of £25 & it wipes the floor with the EP boats it too has a pair of 380's just the same, sadly my motors packed up within a couple of weeks... maybe i was unlucky? the motors have alloy heatsinks whereas the EP boat I own has air cooling (Fins just infront of the props) so I guess this is why the motors keep cooler & havnt burnt out on me like the yacht has, for me the EP's are a great little boat.. but side by side the yacht would leave the EP standing, was very surprised :o

Post by: pt109 on September 24, 2007, 09:27:51 pm
If you were to organise a race between 3 or 4 of these, how do you change the frequencies, as they all seem to be on the same frequency, and as they do not have normal changeable crystals, or can you just solder alternative ones to the circuit boards?

Post by: explorer750 on February 18, 2008, 04:28:53 pm
Has anyone had any experience with its big brother? Thinking of buying one and upgrading the motor, possibly adding a single 700 not two 550

RTR= Ready to Run
ARTR= Almost ready to run

You won't be interested in these Bryan, somebody else builds them and you run them - but quite a lot of people are happy with this, instant gratification!

Do you need to change the radios in this type of boat?
Title: Re: RTR Boats
Post by: Martin (Admin) on February 18, 2008, 08:18:25 pm
RTR  "usually" come with radio but they always state 'what else is needed'.

Another one is ARTF - Almost Ready to Fly or Almost Ready To FLOAT!  ;)
Title: Re: RTR Boats
Post by: Stavros on February 18, 2008, 09:39:22 pm
Yes in some of them,this is due to the fact that you cant change the crystal.Some of them have no range and others get swamped by the proper frequencys.And before anyone asks no I dont know which ones!!!!!!!!!!!!!!!!!!!!!!
One excellent RTR is the Ripmax Interceptor as this comes with a proper 27mhz controller and one can change frequencies

Post by: Bee on February 19, 2008, 09:52:56 am
Can someone clarify this term 'Scratch building' for me please?
I assume it is like lottery scratch cards so you get a boat covered in a plastc film which you scrape off to reveal a RTR boat. Sounds so much easier than ARTF where you have to plug some bits in yourself. No wonder some people are keen on it.  ;D

Here, here Colin!

Yes we've been there, done that, bought the t-shirt and posted on the Forum - Kit or Scratch Build - Why? http://www.modelboatmayhem.co.uk/forum/index.php?topic=6182.0 (http://www.modelboatmayhem.co.uk/forum/index.php?topic=6182.0)

If you want to run RTR boats that's OK, some of us like to do that.
The thought of buying a RTR boat and just adding water is quite appealing....
If you want to build from plans then that's OK too.... the water is still the same!
Personall I like both, depends what you want, your budget, what's available, time limitations, capabilities, access to a lake..... and what mood you're in at the time!

Personally, in the way of RTR,  I the Century Speed boat, "Graupner" Southampton tug & Ripmax Interceptor....

Don't forget Ripmax's Carlson Martin. Or if you want true speed tty the aquacraft range, shown is the supervee 27.

I think in our modern day and age of diversity, respect,understanding and enlightenment we should all try to be more accomodating of our fellow man and his needs and to this end I think it would be a great idea for Bryan to offer to hold classes in how to insert the batteries into an RTR boat and radio.

I know you'd be really good at it Bryan O0
Title: Re: RTR Boats
Post by: Pointy on February 19, 2008, 07:16:00 pm
I hate cheap toy type RTRs but on the other end of the spectrum you have ARTRs like this:

I can understand why builders with skills like Bryan wonder at people like me spending so much money on something I can not even claim to have build myself- what have I learned?
I have considered a fleetscale hull but I really don't have the confidence to build a scratchbuilt superstructure let alone producing a deck with planking details :o Brought a robbe U47 and it was a disaster, spent so much money and had a load of ruined plastic parts to show for it (just how the heck to you cut out some of those parts in that tuff plastic)- actually ended up stabbing myself in the hands a couple of times with a Stanley knife. I did build a Model slipway coaster took me about 7 months but had a difficult time with the painting. I used car sprays and was happy with the result until 6 months later when the painted seemed to start splitting and crazing in parts. Actually brought another coaster kit as I love the subject and get this- I sawed it in half and have successfully lenghend the hull! Thing is I keep thinking of the mess I'm going to make painting it so I've done no work on it since August last year.
 I have learned that building a kit is a very expensive business with no promise that I can pull it off- for me it's a gamble. On the other hand I can buy stuff like the ARTRs on the Graupner site for the same amount of money I spent on just building/painting a large kit.
So with my past experiences what makes more sense to you?
Besides I've added details on the the Prinz and rebuilt parts like the catapault from scratch. Then there was the question of wiring up 3 motors and all the rest of the electronics so some skills are still needed.

one option is take a hull, like I did, buying an aziz-esque hull off stavros, then turn it into something different. 

when I started doing model boats I thaught that I'd never be able to do a full scratch, or even semi scratch, well Im not totally sure where Nord Icelandia fits in the scheme of things as its not based on any real ship, just bits o' this and bits o' that, ho hum,

Post by: Youngat65 on February 20, 2008, 06:24:07 pm
last week I had a chap wanted to come sail with me he didn't have any idea what to do or where to go I invited him up to home , spent quite some time explaining general pondside etiquette he then showed me his pride and joy which turned out to be one of Deans Marine ARTR boats . This chap then came sailing with me and a couple of others the next day , he had a great time and by the end of the day was a complete convert to model boats . This chap had no idea how to build from a plan or a kit , and if he could have he would have had real problems , he had bad arthritis in both hands . The point I am making is without his ARTR  he would never have got into model boating He had a great day out sailing and met a lot of new friends it may have cost him quite a lot in tea and as far as I am concerned I have made a new friend to buy my tea for me

All boats start as scratch builds. RTR are scratched built at the design table by a product designer, so you still get a scratch built boat just a copy of one that is mass produded. If that makes sense.

Ready built aircraft are very big in RC flying, and have a big role to play in the hobby. Likewise, RTR boats have a significant place in model boating, for many of the reasons outlined above. The fact that I prefer to scratch build is simply a personal choice. As has been pointed out in previous posts, many of the RTR models are beautifully made, and those I have seen perform very well. They are just another branch of our hobby.

Perfectly said  O0

The thing that worrys me is, if i turned up at a lake with a £30 dickie tug, poeple might look down me, on the other end of the scale say i turned up with a graupner £700 artr and people came along and chated, would this be because i or someone has spent more money? Or would this be class as oh its a lesser rtr ( iv seen this happen to people before ) its almost like depending on what you bring to lake, depends on what people think of you, say the person that turns up with the £30 rtr has kit boats at home that they built, yet other modelers just think oh hes not into the hobby as much because hes sailin a £30 boat

Im not wanting to start another rant  :angel:

You should join our club offshore1987 we have some fantastic scratch builders, as good as any on this forum and some of them sail RTR models on occassion and we also have people who only sail RTR . In fact we have scratch builders, kit builders and RTR sailers who all receive help when needed and all are welcomed, we have no prima donnas and if you look at our gallery web site you will see the many types of craft involved.  O0

I bought a rtr tug this week simply because if there is no wind at the lake i can't sail my yacht, and as i am concentrating on my u47 kit  building would be a pain.so it fills the gap at the mo fair enough it'll need a radio change but it's great fun in the pond O0. and i don't want to be stood idle at the lake or Bob will make me get the tea! ::)

  but just to throw the cat in surely if you buy a plan to build a model this is just a kit without parts a pure scratch build is drawring plans up first then building, something i have done a couple of times but just don't have the time for now. but as the u47 progresses i am realising the instructions are very vague and a fair bit of interpritation is needed not what i expected from a kit (never built a kit before) but as i'm now modifying it to suit my needs does that make it a "semi scratch built rtr kit?"  :D
Title: Re: RTR Boats
Post by: DickyD on February 21, 2008, 04:23:17 pm

Title: Re: RTR Boats
Post by: Colin Bishop on February 21, 2008, 04:28:21 pm
Changes to a kit as supplied have usually been considered to make it a "modified kit". The changes might involve replacing fittings/parts with scratch built ones or commercial ones or a combination of both. As has been stated at considerable length on other threads, the distinction between  kit built, scratch built or even Divine Intervention  :angel: only becomes an issue if you put the model into a competition and the distinction then is whatever the rules of that particular competition state it is. Otherwise model boats can range from RTRs which come ready charged; just add water; to totally scratch built where the builder has planted the tree, waited for it to grow, cut it down, seasoned the wood and then built the model using plans drawn up by taking measurements off the original vessel whilst probably having made their own pencils and rulers along the way.

Everything else is somewhere in between.

Simple!

Saw one of these down the lake the other day when sailing my club 500. While the hull screams speed it was to say politely not very good. It runs two 380 motors and I was running laps around it in the 500. Can anyone suggest a upgrade.
