I recently bought the ezrun 35A esc and the tacon 4400kv motor. Plugged it all in and it ran fine. The programming card worked. Changed and played with the settings and the car ran fine forward, brake, reverse.

Afterwards I decided to calibrate the thing. After calibration end, the motor blipped once. After that it just does not spin. The esc is delivering juice to the servos and all since they work. However, the motor just does not spin.

Any idea what could be wrong?
