Help. I recently purchased a CX-20 quadcopter which arrived with a faulty motor. I have changed the motor and all 4 now work but after unlocking they only accelerate up to fast idle and no more and the CX-20 cannot take off. I have calibrated all 4 ESCs, gyros, compass and transmitter and everything is performing correctly apart from the throttle. Even the aileron control speeds up and slows down the motors in the right way. Seen several posts from owners with same problem but no solutions yet. Thanks
