Lately I have been having an issue and am hoping to get some feedback. When I first go to fly I power everything up, let the IMU heat up, calibrate the compass and wait for the lights to flash correctly. When I go to start the motors nothing happens - I tried everything, manual takeoff, auto takeoff, turning the controller on and off, still nothing. Usually after 5-10 minutes the motors will start and it will fly with no issues. Does anyone know why this is happening?
