- remove the bell shape cover to help the mechanical fan to suck air out of rotor
The controller also sits on heatsink which are ventilated by two 12v blowers which exhaust is blowing on top of motor.
Which belt have you used ? The Gates Carbon GT ? It has blue teeth, that's the only one which can handle this power in that width and pitch 8 (I presume). "
