Here is my video on a incident, my quadcopter start going upside down. Near fatal crash, caused by lack of throttle, when descending.
Guys keep flip in handy and im thank full for who ever invented that. It saved my quad.
Just to be clear i tried everything to get it back on correct side but more throttle caused it go faster :/. I hit the flip button wala it came back up.
I think somebody need to add this a new feature into the arducopter so that when multiroter is in stabilized mode it will automatically flip back up
