Hi,

I am entirely new to R/C boating and i have just built a balsa 22" hull and have put
a single 540 motor, a speed controller and servo and have the rudder and prop shaft set to go. Basically at the condition it is in
i could take it to the water and it would go. Fast i hope. But i have heard all about cooling and i have none and i am curious to know if i'll most likely need it.
I have a 4200 MAh Nimh battery. The motor is capable of 22,000 rpm loaded. I think i might just take it to the water as is and if the engine starts getting really hot i will consider getting water cooling but i was just wondering as a newbie, how necessary the cooling actually is.

Any help would be much appreciated. Thanks

Here are some pics of the boat. By the way i got a too long prop shaft so the motor sits rather far forward. (the motor is not in the boat in the pics)
Also the hatch doesn't have anything to secure it down yet and i am working on this.

Constructive criticism expected as the boat is tacky on all levels. Not being a professional boater i just don't care to a certain extent.
Also in the pics the rudder is not secured.

P.S. I'm sorry about the paint job as i havn't properly painted it yet.
