Hi Guys

I'm looking for advice on how best to proceed with this little project. A friend of mine is building amazing static models of offshore powerboats and I asked him for some mouldings that I can convert to a little RC racer. The model is 420mm X 95mm. I was thinking of a small transom stinger/rudder assembly (preference would be aluminum) and Brushless/ Lithium Polymer for power. Maybe 1S.

Much of what I see offered is too large. Any ideas on what I could use for this.

Thanks

He's got one near completion. I'll get you some pictures. Any idea on miniature motor, speed control etc. I may have to manufacture the rudder and extension. I thought about a standard through the bottom prop shaft but going to give it a try with surface drive. Need to be careful not to overpower it. 20 amps will be plenty 3.7 v. I'm not expecting much in the way of performance but want it to run at somewhat of a scale speed.

Hi Mike,

Have you considered looking at some of the gear in the 1/10 scale or smaller electric cars? Seems like that size motor/ESC/battery could be adapted. If anyone could figure out how to make conversion equipment, you'd be the guy.

Happy New Year,

JD
 
Sorry only know of european sources but might give you inspiration.

I think your best bet would be to look at MHZ Gecko boat. The size is similar and I think you'd be surprised how much you can stuff in. Including a brushless engine ans small lipo pack... Unfortunately no scale drives the drives that comes closest are made by Werner Dieckmann of WD200

as for engine: I used a 3700kv brushless with either 2s or 3s battery: about 1500mAh gives you about 10 minutes run time...
 
Sorry pressed submit but wasn't ready: To show what is possible: a gecko was even converted to methanol 0,8 cc by curt conrad. ( you might need to be a member of X-treme forum)

As for the engine: use outrunner, no cooling needed. The really small size ones called mystery, something like this will do:

Thanks Jerry, Happy New Year to you also. I've been looking at the Aquacraft Minimono and that might tick all the boxes, gives me something to play with also if the Cigarette is a disaster on the water. Too much power but it may run on 2S or maybe a small prop.

Thanks rhomodel for the MHZ info. I like the steerable drives, it would keep it somewhat scale, bit pricey though. I am going to look a little more at the smaller engines you mention before diving in.

Cheers
 
Phil (http://www.raceboatmodels.co.uk/) has been making custom models out of solid wood for many years as a sideline. He has decided to make a serious business out of it. Making the plug out of wood and now builds the hull and deck from glass. The model in the picture is glass. I have a static model ordered but also wanted to put one on the water.

Mike, did you ever work out the power system? If you are hell-bent on 1S (I would NOT be... I'd do a very small 3S system... Lots more motor, ESC, and battery options), let me know... I think I can advise.
 
You need to see if he will make a plug for a 50" version..and I will make molds of it!
 
After looking at the web link your mate Phil is an Artist! They are brilliant those little boat's! A job very well done!!
 
Thanks Darin, A 3S system it will be. Will most of the 3S systems work on 2S?.

Thanks Andy, I am looking at that. Nice hardware but radio not included, it does look like they include a rudder servo. I am definitely going to take a boat apart for the running gear. Much cheaper!

Much appreciated
