Is this radio controlled? What kind of control is available? Do you want the entire motor drive circuit? How big is this boat, it must be speedy if the motor draws 35+ amps!
the boat is radio controlled and yes i need all of the circuit project.the control will be used on more than one boat,but i could just make a few,but
with different amp loads. :lol:
You might also consider using model car speed controls?, these are easily available in various powers - depending how much you want to spend!. The ones I've seen always have multiple FET's in parallel, in order to increase the power handling, and to reduce their voltage drop - the more expensive the controller, the more FET's used.
