The problem is that when the motor is not attached to the transmission all works fine, but when I attach it to the car and throttling, the motor seems to be cogging, and the car can finally go forward but the speed is very low and the motor gets very hot extremely quick, so I must stop the car. If I block the transmission by hand it produces the same effect, the motor gets very hot and if I hit full throttle the ESC fan becomes OFF and when I release the trigger it starts to spinning again.
I'm using a Xerun v2.1 120A with a LRP X12 13.5T with STOCK firmware and 0 timming/turbo.
Regards.
Whats your FDR? It seems like you have a drive line problem more then an ESC issue. The fan is stopping because the motor is drawing so much current from the battery, that the voltage is dropping to much for the fan to spin (similar to a dead short, or a motor that is stuck). That also explains the heat.
Is your driveline free spinning? I am not to familiar with LRP but do you have the "4 Dot Ring in"? Thinking you could have to much endbell timing.
