Could someone help me in log file analysis. Today we had a crash with a quad with pixhawk cube and 3.6.12 firmware. The copter was hovering at 1 m height and after few minutes all the motors turned off. When it dropped we activated the emergency motor stop switch but even after that couple of motors were still running. I have attached the log file of the flight.
Update to AC 4.0.3, it’s stable, your existing parameters will convert nicely and there’s some important fixes.
I’d say probably get up a little higher away from prop wash and ground effects. The whole time you’re flying the Baro thinks you are at a lower altitude than when you took off. GPS is not providing a good Alt reading either, again more altitude will help with that, away from clutter and multipathing.
