S6R failure - July 22 17

Frsky S6R failure - At 2:33 you can see the airplane oscillate left to right (uncommanded) then begin to turn right (again, uncommanded). After a few seconds, it becomes uncontrollable and goes down.

The whole flight was very shaky, not smooth at all.

this happens to me twice recently, did you find the reason? in my case self check during the flight.
