jasonshort 3558567aad Added new leveling command. Hold the trainer swicth - ch7- in and the copter will adjust the ADC_OFFSET based on the roll and pitch command needed to straighten the copter.
no roll and pitch input means no change. Flicking will still update the throttle cruise value. Please check I have the signs correct!!!
