Up until yesterday, things were going well. I could loiter, RTL, and fly auto with no issues. But there was one little annoyance-- The heading was always pointing about 15 degrees off from the actual course the hexa was flying in auto mode, with the result that the hexa was always flying kind of sideways.
I decided to try the COMPASS_MOT procedure, to see if that might help. I did it, and got some nice low values, Unfortunately, my first flight with loiter, the hexa was now doing the toilet bowl thing. I have no idea if COMPASS_MOT fixed my yaw problem or not, because I went into the parameters and zeroed out the values to see if I could restore the prior good performance.
Next test flight, everything looked good. It loitered and RTL'd until I was coming back to land, and suddenly the controls started getting flaky on me. I ended up crashing hard from about 3 meters and breaking an arm off on my hexa.
I replaced the arm and sent it up again. This time, when I put it in loiter it didn't take long for the hexa to apeshit and start veering all over the place. Controls had barely any effect. I switched modes rapidly trying to save it and managed to barely avoid a bad crash.
So, Log Gods, WTF? At this point I'm afraid to fly it. I have no idea when is going on all of a sudden with what was a nice flying machine one day ago,
Attached are tlogs from crashes 1 and 2, plus the parameters saved from when I had COMPASS_MOT.
Thanks in advance
