At the moment, I'm using a hall effect throttle, where the middle 15% is "zero", and clockwise rotoates the motor one way, and counter clockwise rotates it the other way. It regens whenever you turn the throttle the opposite way that it wants to turn. In real life I think we'll use a variable pressure switch on the brake or something. Then, if you press the brake, it regens, and you slow down. Once it reaches the max regen that you program, if you push harder, then the regular old brake kicks in. That's the idea at least. I have no way of testing it at the moment. I guess I could rig a brake pedal or something. It's just that my motor has no "whatever that's called" when it's really heavy, and hard to slow down. I cranked the regen up to 10 amps this morning, and the motor post went from about 1500RPM to 0RPM in about 0.01 second, like it hit a brick wall. Not exactly what we are shooting for in real life.
