This may just look insignificant but it is not, this is a considerable large ark to the left, sweeping the aircraft 180 degrees. Plotting it in plot.ardupilot (55m20s)you can see the significance of this banking. At this point airspeed was 17m/s, so should not be stalling. (VTOL kicks in)
This happens 3 times during this section of the flight.
This to me would indicate a mechanical issue with one on the Alerons.
The final bank band and flip; Airspeed is 18ms
At the point then the VTOL motors kick in (1758363) the aircraft is at -117 deg: -
The dominant motors are Q10 & Q12 being Rear Left & Rear Right !!!
This is odd as this flips the aircraft tail over its nose.
I would have expected Q10 & Q11 to dominate with Q11 being the higher. Pulling the aircraft nose up and left side up back to level.
This is odd.
In any event, I believe this hard bank left at -117 deg was too late for VTOL assets to rectify the attitude.
I will look at the aileron servos and links in the morning.
My feeling is that the left roll is merely the beginning of total loss of control by the flight controller. In the image below, you can see that the plane was just tumbling to the ground. Even with a loss of aileron, where was the quad motor assist? What version of firmware were you running?
