Hi,
A serious crash two days ago motivate this first post on the forum. I would appreciate any help as I can't find myself any explanation.
Here is my config : Arduplane 3.7.1, pixhawk, conventional custom plane (3 axis, 1 motor).
The crash happened during the second flight of the day. The firts flight didn't encounter any problem. Both were survey flight in auto mode, including auto takeoff.
After log analysis, it seems that the problem occurs just after switching from waypoint #27 to waypoint #29 (#28 was a DO_SET_CAM_TRIG_DIST command). Then the desired pitch doesn't change significantly, but real pitch goes to dive and RCOUT_pitch value rise to >2000 (i.e. full pitch down).
I can't exclude totaly a mechanical failure, but it is unlikely.
I upgraded to 3.7.1 the day before.
If anyone is willing to have a look, here are the documents: http://ovh.to/U5oBAu2
Best regards
