I had a crash where I don’t cant find the reason. Power or software failure? The airframe had up to that point ~30h of flighttime without issues.
Frame: Tiltrotor VTOL
- Cube Black
- RasPi Companion
- LTE for MAVlink and video
I was flying a auto mission monitored via LTE connection to Missionplanner, QGC and live video.
1:20h into flight the plane stopped sending mavlink messages but the video stream still worked.
I saw the plane crashing via live video ~12sec after the last telemetry data where received.
The plane was resting 200m from the last logged (dataflash and tlog) position.
I have ~8 years experience flying Ardupilot (Copter, Plain/VTOL) but can’t find this time the reason for the crash.
For me everything looks good regarding power und hardware…
Some hints how to detect a software or hardware problem would be nice!
Here some graphs from dataflash log.
