Arduplane version: 3.7.1
Plane: Ritewing DRAK
Description: Auto takeoff into AUTO mission at 100m ALT. Mission completed successfully.
At the end of the mission mode changed to RTL - at that point the plane lost ALT to 50m but recovered and continued normal RTL.
Then I took control via FBWA for few seconds and then switched mode to AUTO to re-start the same mission. At that point the plane started diving, I tried to re-take control via FBWA and pitch full up but nothing helped, the planed dived to the ground.
There was NO mechanical failure so that is not the cause.
BIN and TLOG can be downloaded here:
Would appreciate any insight to the the cause.
