One of my subscribers asked me how to select the way that you turned on 'self level' on the KK2.0. This video shows the answer.
The following is from the manual available at
"Arm it by give right rudder and zero throttle for a few seconds. It will beep and the LED will turn on. Do not arm it until you have put the multicopter on the ground and stepped away 5 meters.
Safe it after landing by holding the rudder to left with zero throttle. It will beep and the LED will turn off. Do it before you approach the multicopter.
Turn on the Self-levelling by holding right aileron while arming or disarming it. Turn it off by holding left aileron. Alternatively you can assign this to the AUX channel."
