I found that putting the BK controller back makes the motor behave as it should. However I dont want to risk another expensive controller catching fire. I have come to conclusion that the motor is not defective but something else in the setup may have been the limiting factor. It could have been a faulty controller or it could be that the truck that weighs nearly 20kg is too heavy. However anybody watching the truck would have been impressed with the torque / acceleration for the first 2 minutes..... Remember the pinion has nothing to do with the motor and Schulze controller - I have the motor on the bench and holding the shaft with my fingers. I can stop the shaft rotating with my fingers when the motor is coupled to the schulze at low rpm. On the BK controller I cannot stall it that easily. I coupled it to a watt meter and noted that stalling the rotor drew about 14 amps and low rpm but once the rotor stalled the schulze stopped drawing amps. What I dont know is if the BK controller overheats when the rotor is stalled. I cannot hold the rotor with my fingers to test it out.
