Be sure to go down a few teeth when u put it in so you dont burn it up lol. Always good to be under geared and save a motor than be over geared and burn it up.
Is the only difference the endbell timing setup? Or does the motor have different properties as well? Does anyone have the Kv readings for both motors as this is usually the best indicator for the type of motor (rpm vs torque)
