1. When the throttle is fully down three motors are spinning very slowly and one motor doesn't spin. When raise the throttle a bit the 4th motor that was not running start to spin. Can someone advise what could be the problem? I synchronize all motors as in the guide.
2. Is there a way when motors are armed and the throttle is down that the 4 motors will not start to spin?

Whenever I have this issue it has been the ESC's are not calibrated to the transmitter.
Is it possible the calibration is not being saved.
