The thing is that both of the times I've encountered this glitch it has been immediately after applying right aileron. As you can see in the video I have started my right turn, then it locks out and applies full aileron in the same direction that I was starting the turn to.
My thought was the motors didn't stop; but aileron went to one end of travel could failsafe values for aileron & throttle channel be reversed ie throttle = hold & aileron =zero????
Another thought - commonest failure mode of a servo is full to one side. Not necessarily every time. Changing the servo is cheap while you work through other possibilities.

Thats definitely something to look at. Curiously though, my friends P-38 with his Taranis and his X8R receiver encounter the same glitch like I stated, but I know for a fact that he doesn't have any failsafe set up. So my radio with my failsafe encountered the same condition as my friends radio without failsafe in two different places with different servos, different receivers and different transmitters. If there wasn't these similarities in the two incidents I would have already replaced the servo. I'll confirm all my programming to double-check.
