Yesterday I set up my Tarot680 with autotune and some flight tests and my hexacopter did fine (a short clip from yesterday here)
my internal compass was fine except when flying backwards for over about 10s seconds the copter yawed clockwise about 90 degrees;
today used an external compass - after calibration i took off in position hold - fine for about 1 minute; EKF2 IMU1 ground mag anomaly, yaw re-aligned showed up and suddenly the copter dropped like a stone;
I checked all cables, power module, everything still connected and working after the crash (except a broken motor mount); after the crash I switched mot emerg switch on and off again - props spinned again ( I shut them off again) after the crash; - so I assume autpilot was still working and didn't power off (copter was still armed);
during crash i wasn't using my transmitter - i was looking at Missionplanner at that moment;all files on my sd card are corrupted and i can see physical damage on one of the sdcard's contacts;
here is my telemetry log - all i have - and very very bad link quality doesn't give much hints;

using copter 3.4.6now my question is: would a corrupted sd card make the copter fall out of the sky?
