Can someone explain "Desired Roll" vs. "Roll"?
I have an unexplained crash that occurred at the end of a long autonomous flight. Suggestion in the manual on log file analysis indicates differences between desired and actual values might point to a mechanical failure. However, that doesn't appear to be the case in an s900 hex crash with a pixhawk.
I notice the desired roll becomes quite large (positive) and large oscillations occur around the roll axis.
Is this a failure of the algorithm controlling attitude or am I misinterpreting the telemetry?
