Hi folks,
I began by launching the drone in mission mode, maintaining a hover in position mode at an altitude of 2 meters. Then I activated the “automatic flight mode switching” option on the rate controller PID Tuning page. This caused the drone to unexpectedly ascend and drift leftward. I had not yet enabled auto-tune. I intervened to decrease the altitude, but the rotors ceased functioning, causing the drone to drop vertically from a height of 12 meters, resulting in damage to two of its arms. I have shared the logs and a partial video, as the drone moved out of frame during the incident.

I’m seeking insights into why the drone increased its altitude and advice on measures I can take next time to prevent this issue.
