[Bixler 2] 3 times Crash series with APM 2.5 and Pixhawk


Hello,
first of all: Greeting from Germany

had now once again a (mysterious for me) crash with my Bixler.

Last summer I crashed my first Bixler with APM 2.5 while turning in the air in a tree. Was then almost a total loss. In the moment where I turned him to fly back, he came down into a swirl.

Then the new Bixler with Pixhawk. Over the middle of the field from 20 meters in height, crashed again when turning (also because of the death swirl). FBWA each time.
Have him then last summer again glued and fly for a week now again.
Last week I start, and flew after about 2 minutes, come back and crashed while turning into a swirl - pretty bad.

Check out the video in, I think that speaks for itself: /

Bixler 2 Full Crash with Pixhawk (1 min 42 sec)


Can anyone help me? What could I do wrong ?? Two planes - two Autopilots.

Shows you had possible problems with both GPS and Compass on the self analysis.

Looks like it went int a locked left turn.

Was "fail safe" set? Maybe a brown out condition?

Also from the sound, it sounded like the motor was a little erratic at the time of the problem.
Acted like it slowed down right as the turn started, got quiet, then sped up again.
Was that you or the system doing it?
