I am strungling with my X8 frame (3DR X8+ with ArduCopter V3.2.1 and pre-installed param). It was fine flying in Belgium, but after transportation to Peru I observe some issues during navigation (auto/RTL). I have redone the compass calibration many times but no improvement. No crash yet, but defenitly need some help in analysing the logs. Thanks!
Can you post the dataflash log?
Looks like the quad is hovering nose-high, does it have tilted motor mounts or something?
High vibrations might be part of the issue.
I checked again and all motor mounts look ok... but after such a long transport maybe indeed something is off.
Dataflash logs in attach.
