"1. Check that your CH7 switch goes above 1800 on the MissionPlanner’s Hardware > Mandatory Hardware > Radio Calibration screen.
Set the CH7 Option to Save Trim on the Software > Copter Pids screen and press the “Write Params” button.
With your CH7 switch in the off position, fly your copter in Stabilize mode and use your transmitters’s roll and pitch trim to get it flying level.
Land and put your throttle to zero
5. Release the roll and pitch sticks and switch the CH7 switch high for at least 1 second.
- Reset your transmitters roll and pitch trims back to the center and fly again and it should fly level now. If it does not repeat steps 3, 4 & 5."
