This afternoon I flew a photo mission with my quad in AUTO mode ( take off and landing included in the mission). I have previously flown similar missions without a glitch .
Take-off and photo mission went according to plan.
However once the quad returned to launch (altitude 40m), and before starting the landing stage :
- It proceeded to circle in a spiral path , moving further away
- I switched control to RTL,
- It briefly jerked but did not proceed to RTL
- After another spiral moving further away , it crashed on some low trees
Checking the logs, GPS satellite link was never lost...
I have very little experience checking the logs but I really want to understand what went wrong.
Here attached is the flight log:
Any help explaining the cause of this incident or interpreting the flight log data is greatly appreciated.
- 3DR Quad- C
- APM 2.6
- Arducopter 3.0.1
