You can run it with the sensor wire unplugged. Sounds to me like you have a sensor problem in the motor or something wrong with the ESC. I would try loading the firmware again(to the same version). If that doesn't help any, do you have another motor you can try just to figure out which unit is the problem? Or even another ESC with the 4.5?
