Hi, I have a Syma X8C quad copter, one of the rotors (rear counter clock wise), runs at full power from power on. At initial power up, sometimes I get a normal response, sometimes the rotor spins up to full power and stays on. In every case, once synced to controller, it runs at full power irrespective of controller commands. The other three work as normal. It started as an occasional problem (it would spin and stay at full power for a moment or two). Now it runs constantly. Question: is the likely culprit the controller or the copters main board?
It sounds like a gyro problem or the component that controls that motor is defective, all on the board in the quadcopter. Being that once it syncs kind of makes me thing gyro, but either way…
