Default Im Back, and i have a few questions : NEW UPDATED PICS

Hi all, im back again. Hoping to get my boat done fo next summer BUT i wish to know if, instead of making it nitro, i could have 2 12v electric dumas motors running it instead because i simply cannot afford the engin for the nitro setup., would running a double outdrive- twin rudder setup with 2 dumas motors and a fair few batteries work? the hull i have made is a red fiberglass hull 36" long that i made nearly a year ago... Would these two motors and suffiecient batts get it goin FAST? if so, i would use them two motors, two props( need props recomending aswell) and 2 ESP's (pref mechanical), if it wouldnt, does any one know wher ei can get a real cheap O.S. .46 or larger (marine, NOT UNDER .46)
thanks guys.

also, hows ross (macelod doing, haent been on for a while)

In general, to get fast speeds out of electrics you're going to need to spend as much, and most often more, than you would for an engine. Personally, I'd go nitro. What do you consider cheap?

The Dumas motors are really slow as they're made for scale ships and the like, even slower than a ROAR stock motor by about half.

go to www.offshoreelectrics.com get yourself a graupner speed 800 and some decent cells if you dont have them already and get yourself a esc thats the best way and best price
or save up and get a fiago brushless the 12 XL
thats the best setup

Default RE: Im Back, and i have a few questions

Thanks for the advise 69dart, i'll see what suits my budget when i get chance to look, im thinking about buying a [link=http://www.rossisales.com/boats4.html]speedmaster hull[/link] but im not sure, i have a hull, cba putting stringers in myself. Shipping is a bomb from us to england though , what you think, also, this emans i wont be able to use a .46 engine because the speedmaster hull is .21, what you think? should i goto that, or do you think i'll fit my favourite .46 in it? bear in mind i want it to be dangerously fast. or will it just be too fast and flip?

Would an O.S. . 21 buggy engine work as a water cooled option? or does a buggy engine lack in power for marine?, pleae name any others including water cooled, also, if anyone has a cheap engine of required size (.21 or .46 either considered)

Apparently that hull can also have an aircooled engine i have heard, if so, could you recomend an aircooled engine and a water cooled one for if i were to buy that

Speedmaster makes good hulls. So does Microburst, Twincraft, and others I can't think of right now. You could also get plans for the Wild Thing and build your own. Both .21 and .45 are good sizes. I like the .21s because they are so economical on fuel. OS and OPS both have good, reasonably priced, engines in this size. Of course I also like .45 engines. In a mono the .45s will be a little faster, but a well setup .21 is still a blast.

Default RE: Im Back, and i have a few questions

i started making cardboard templates for my stringer/bulkhead assembly today, should be ready to put onto wood soon, my stringers are going to curve up towards frnt or boat rnt they, becasue of the shape of the bottom of my hull.

The notches are where i will bond the bulkhead i have made (3) to the stringers for strenght, the bulkheads will only be as high as the stringers., would this be of iof they didnt reach the freeboard or shall i have them so they just reach the freeboard?


Heres a diag to show what ive done (from side, with 2 stringer obv')

Ive also taken about 2 inshes off the front end of the stringers... less of a curve that way

here my hull with cardboard templates in place ( minus 1 stringer) what you think so far? does this look right? if not please say.

Also some good old english currency in there somewhere :P, my body spray. and a bulb. hehe
also, is the engine mount bit right? and the foremost bulkhead isnt supposed to meet the hull at the bottom in between the stringers..

Move the one that is furthest to the front , MORE to the front ... ( couple of inches ) so that you have room for engine adjustment ( able to move engine forward in case your CG is not right where you have the area for engine mounting . and eliminate the second one from the transom .
And , if available , use marine ply for the stringers and supports .
Also , did you calculate the distance where you have the section higher for the engine to mount to , or , just guessed ? ( remember to roughly calculate .... and if you make it oversized - too long engine area - you can always trim her afterwards , BUT , if you make it TOO short , you can NOT add the needed area )

Mental - I think it looks pretty sweet. What ever paint you use, just make sure it's nitro proof. I used automotive paint on mine because it runs on gasoline. I'm not sure it would stand up to nitro fuels.

My boat is a scratch built shallow Vee hull. 42.5in long x 11.5in wide. powered by H2O cooled 25cc Homelite w/big carb and tuned pipe. I will try to post pics this weekend.

cool, sounds nice dude :P, well, if i paint that sharks face on my hull, i dont think i'll be spilling nitro there, so i would use vehicle paint, however, i think i'll use a brush and pinstripe the edges of the teeth and stuff, then use a slightly thicker brush for the mainbits:P, should look champion when its done..

Dave Marles at Prestwich models can supply you with Octura props, he will sharpen and balance them for you if required, he is based in the UK so shipping charges will be quite cheap.
The link as follows
[link=http://www.prestwich.ndirect.co.uk/]Prestwich Models[/link]. Nice guy to deal with, and will probably be able to supply you all the parts you require.

Overseas ,,, sorry .. but if you want raw , did you try PRESWHICH ( or how ever thats spelled )
Otherwise , here , there are a few guys that DO , SB the props , BUT , they get a good dime for them .
DASBOATA ( Chris ) is a VERY reputable seller ( N.Y. - I think ) ... AND he sells SB'ed as well as raw .
Then if just RAW , try Brian at ROCKET CITY RACING dot COM
or JIM at ABC props ( also online --- AND he also does SB as well )
There are others , but none that I can think of , off the top of my head that I would recommend ... ( sorry if I left anybody particular out )
