Need help please diagnosing why this fault has happened.
We have a Foxtech Gaia Elite Pro fitted with the Cube Black.
We followed the setup steps in Arducopter and it has been flying reasonably (could be better in loiter) for about 10 hours.
However during a reasonably challenging survey in mountain ranges using terain following, we experienced a strong yaw to the left with the error message "potential thrust loss (5) and followed by an over correction to the right "potential thrust loss (3) , nearly 90 deg both ways. There was also a marked drop in height of about 5 m whilst the reported faults occured.
The wind was reasonably strong from the south of maybe 10m/s and the down wind attitude was quite level to fly at 6m/s.
The fault occurs at 9:23:05 in the timeline.
Its a scary thing to see happen especially when it looked fine for some time.
Could severe turbulance / downdraft have caused this?
Are the (5) and (3) numbers actually the motor arm numbers?
