I am building a 46 inch model based on the moonraker do to thickness of fiber glass ( 4 /5 mm) thick it is quite heavy I would like to fit electric motor and was recommened to give Action Electronic`s from a member awile ago I rang him today but he think I need brushless motor to give it adequate power and he recommened I asked again on this forum he said a member called Nick75 is well up on brushless motors so Nick if you pick this up or anyone else on the forum I would be thankfull for any advice.

46 inch eh big boat that, especially for a fast one. Ill help a bit but first we got to decide how many props you want and what kind of budget your working too?

Hi Mad Mike
I am open to your suggestions I was going to use a 40 HP IC engine when I started to build it 30 plus years ago but then left it and now have decided I would prefer to go for electric I have one prop shaft fitted at the moment but could remove it if needed to, As for cost hit me with your suggestions and approx cost I always have expensive ideas Peter.

My most expensive idea was definitely the wife and Kids

Seriously though I'm interested in watching your topic but I don't have alot of experience - so any clear explanations will be read with much appreciation

Regards Dave

what size prop you got on it?

OapPETE · « **Reply #5 on:** November 09, 2011, 11:31:42 pm »

No prop fitted just the shaft I think it would take 55 or 60mm not sure will check tomorrow as it is in the loft where I do the building I think it is a 4mm

Hi Pete, Dave from ACTion will help you a lot & though he is a business he does not play games with your money,he also does nice wiring diagrams if you ask him nicely.LOL. MadMike is a very helpful guy & so is F1. With this kind of help & other members of the forum also, you will not go wrong. I must say I am totally clueless when it comes to the fast stuff, tugs are my speed, just thought I would throw in a little bit of reassurance for good measure. Mick B.

well to power a boat of this size youl need to put a bit of money in it. it will be in excess of 100 pound at least. me perisonally am a budget builder so here was i would use. Other people will disagree:

motor

brushless esc:

4s lipo:

if you go lipo youl need a balance charger, these prices vary depending on quality but expect to pay around the 20 pound mark. if you get this one:

http://www.hobbyking.com/hobbyking/store/__5548__IMAX_B6_Charger_Discharger_1_6_Cells_GENUINE_.html

you will need a wall acdc adapter. there is another one on the same site with the adapter built it if you want to spend a bit more:

http://www.hobbyking.com/hobbyking/store/__6478__IMAX_B6_AC_Charger_Discharger_1_6_Cells_GENUINE_.html

anyway thats what i would do. If you dont want to go down the lipo route it is possible to use nimh or even a lead acid battery but they might add weight.

MikeA · « **Reply #8 on:** November 10, 2011, 03:38:24 pm »

there is another way and instead of using a 4s lipo use a pair or 2s lipos of the same type and make. If you then decide to up the speed you just add an extra one in.

for example 2 of these and then 1 more to make a total of 6s. that would probably make your boat stupidly fast lol

http://www.hobbyking.com/hobbyking/store/__17252__Turnigy_nano_tech_5000mah_2S_35_70C_Lipo_Pack.html

with these smaller batteries you can use these smaller cheaper chargers. youl need a 12v 1amp adapter for it though:

MikeA · « **Reply #18 on:** November 10, 2011, 09:05:24 pm »

very nice. whats it like working in the attic? i might be shoved up there out of the way.

what do you think to that list i gave you too?

OapPETE · « **Reply #19 on:** November 10, 2011, 09:25:08 pm »

There is plenty of room up there it is like another room just a bit restricted with height at back of worktop do to slope of roof but is better than out in the garage in the winter.

It sounds confuseing but with help I think I will go for one or the other

SteamboatPhil · « **Reply #20 on:** November 10, 2011, 09:51:10 pm »

Don'y know much about brushless, however Dave (Action) does a brushed 900 motor which on 24 V (and his big speed controller) would make your boat fly, and you would get a run time (at full chat as it were) of over 1/2 hour (I know because I have the set up in a straight runner, and Stavros stuck one in a 46 in perkasa) scary stuff
Hope it helps a little

MikeA · « **Reply #21 on:** November 11, 2011, 09:27:35 am »

pete i found this vid of a 49in perkasa with a 900 motor on 24v. if you went this route it would be a lot cheaper than brushless.

lol i was just posting a pick using the "additional options" button as ive not done it that way yet. it was just a test to see if it works, that narrow boat hull is just a pick of the net. thought about making one in the future
