could someone else have a look at my log file please? The copter took off in Stabilize, hovered more or less well at 1 meter height (kept in place by throttle, pitch and roll inputs, not super stable). The second I gave it a little yaw one arm dropped like 25° and the quad accelerated hard for 5 meters and crashed into a shed right next to me. The battery flew out of the copter on impact, so the end of the log is also the end of the flight. If it helps I can post/link the video of the onboard Mobius.
I used the APM Flight Log Analyser V18.104.22.168 and it says that RTL was activated and some GPS glitches happened. But the copter did not rise to 10 meters as configured - just accelerated as hard as it could into that wall. Also it did not flip or crash totally uncontrolled, instead I had the impression that the arm dipped and then stayed at that angle while accelerating, as if it wanted that course - but RTL at 1 meter?
The copter had crashed previously (somewhere else a few weeks back) and the GPS ripped off, I had to resolder the backup-battery. Perhaps it was damaged… I’m using the HK Pilot 2.5 clone and have replaced the 3.3V regulator. Following the instructions given here: youtube.com/watch?v=1q6jjha5rgU I just checked and the new regulator is still working fine.
Thanks for your help!
