Fanboat ideas

Hey guys A freind of mine Chris (some of you may know him as KofC) is building a nitro fanboat and seeing his build I'm thinking of building a brushless fan boat anyone have an opinon or ideas for that?? What kind of electronics. To anything you think would be cool to do with it. I'm just looking for input of Anykind

I think Nitro would be better for a fan boat because it would be so much more realistic scale

This is true but then I can't run it at my cttage parents would shoot me

Good point do an outrunner motor then

I'm thinking of building a gearbox for it that uses a spur gear on the motor and a pin on the drive shaft so I can boost the rpms seeing as there really won't be much resistance

Ok well I've done some research and I'm scrapping the gear box idea I'm gonna have a 9000kv motor and a 14" prop. I've also got the rough dimensions it looking like 18"x26-30". The material I'm gonna use at this point is foam with wood. I'm gonna use two rudders and an indirect servo system alowing the servo to me in the sealed area of the boat. I'm short on plans for how to keep the ESC cool any ideas would be greatly appriciated. I'll be sure to post pics through out the building process. Thanks guys for any imput feel free to throw any ideas you have at me. Thanks.

Traxxas has a water cooler esc, or you can use an esc fan or a fan out of an old computer. You could also use an ice pack. Not the plastic kind that sweats, but the fabric type for injuries, that folds bends to any shape you need. As for not having resistance, water is a lot of resistance to push. Water is 800 times the density of air. That makes a huge difference in some cases, such a planing hulls vs. a semi- displacement hull. With a fan boat it's all greatly reduced, but you'll have to balance your weight so when you don't come up on plane and keep going into a flip. You may have to experiment with different pitch and size pusher props to keep things cool. I'm guessing your doing a hydro plane style as opposed to a swamp boat.
A swamp boat will need to displace more water till it gets on plane, once on plane it'll go over anything wet.
Check out hydrofoams, they go on water, land and air.

Thanks kieth I was thining of using a flat bottom with slanted sides and front alone with angled pieces at the front th weight balance I completely over looked that I'll probably just throw some metal in the hull to balance it.
