What all is in a motor speed controler? the better ones basicly make a square wave that varries the on part of the freqency, right?
I know enough about electronics to know that I wouldn't trust a controler that I built, my citicar is pretty small, and the motor is on the small side for a road going vehicle and still, the cables that go to the controler relays, battery, and motor are all rather big, the relays alone could cost $500 each to replace if I want decent quality, and that is just an electromagnent that pulls a simple switch closed.
