Flying in Auto mode my plane made nearly crashed in the ground making a right turn and decent.
After waypoint 4 a right turn and decent from 20m to 5 m was requested, however the plane fall to 40cm (above ground), then plane corrected to the requested 5m. After this it made a perfect safe (auto) landing, as programmed.
Before this flight I did an Autotune flight (tuning roll and pitch). (unfortunate no log)
Something is completey wrong, but I have no clou what ??
See the attached, parameter_file, data_flash_log and telemetry_log, the actual take off is at ~70%, the nearly crash at 85%.
