While descending in attitude mode the copter went unstable and flipped.

Any type of feedback appreciated.

Clearly an observed runaway, which means that its either a mechanical failure or improper tuning (e.g. minimum manual throttle too low).

Ok thanks!

I am not the owner of the copter but will communicate that MPC_MANTHR_MIN could be increased to see if performance improves.

Cheers
