Last saturday I went to do some testing on my quad and I had an awful crash, this is what happend:
- Armed the quad with Mission Planner in Stabilize mode
- Moved the a few meters up and a few mts away south
- Switched to RTL
Then the quad went to the north at full speed slowly decreasing the altitude until it crashed.
I don't have a clue of what happend because, the GPS had a perfect lock, the altitude was correctly displayed, and the compass showed the correct heading, I'm just astonished.
This is what I use:
APM 2.6 fw 3.2.1
3DR 915Mhz Radio
3DR Power module
HJ 450 Frame
Also use APM 2.0 RC1/RC3
What am I doing wrong?, ideas?
