I know lots about electrics. To sum this up:
A brushless motor runs on 3 phase AC waves. To reverse the direction of the motor, swap any 2 of the 3 wires going to the motor. This reverses the phase cycle.
The brushless speed controller is locked on 75% max power in reverse. When going from forward to reverse, you need to make a 0.35 second stop in neutral, or it goes to brake.
The white socket in the ESC is for a fan - why not add one?
