Tandem Wing Tilt-Hexaplane Crashed during Auto Transition (Rolled Right) - Log Attached

ArduPlane VTOL Plane

Hello,

I am seeking advice on a recent crash involving my custom VTOL aircraft. I suspect an issue with the transition settings, but I cannot pinpoint the exact cause of the failure.

  1. Aircraft Configuration
    Airframe: Tandem Wing + Hexacopter (The center 2 motors of the hexacopter are configured to tilt for transition).
    Flight Controller (FC): Pixhawk Orange Cube.

  2. Flight Modes Tested Successfully
    The aircraft flew stably and without issues in the following manual/semi-automatic modes:
    Q_Stbil (Quad Stabilize)
    Q_Hover (Quad Hover)
    FBW-A (Fixed-Wing Fly-By-Wire A)

  3. Crash Scenario
    The crash occurred in Auto mode
    The aircraft took off and climbed to an altitude of 100 meters.
    During the transition from hover to forward flight, the aircraft suddenly rolled violently to the right** and crashed to the ground.
    The system was unable to maintain roll control during the transition phase.

I have attached the necessary log files and video of the crash for detailed analysis.

BIN file:** 00000030.BIN
Tlog file:** 2025-10-19 14-09-51.tlog

I would greatly appreciate any guidance or insights into what configurations might be incorrect, specifically regarding the tilt mechanism or transition logic for this complex setup.

Thank you in advance for your time and expertise.
