Anyone know what size screws im going to need to hold the motor in place? Im guessing I can get any 1/8th pinion to work with the motor as well?
The motor is going to use 32 pitch gears 5mm bore that you can get at you lhs. I believe mod.08 will also work. Just double check which spur you installed. Do not use 1/8 pinion as they are generally mod 1 and will not work. Im not sure on the motor screws.
