AC3.5.4 EKF Error - Land Mode initiated

I was a minute or so into the flight when I lost control of the aircraft, and regained control by changing to Stabilize mode. Log indicates I had an EKF error at 17,327 which caused a fail safe into Land mode.

Hexa - 17" props & KDE motors running Cube and dual HERE GPS units.

Any insight as to the error would be appreciated. BIN attached.


way too much vibrations, and sensor clipping, also it’s vibration profile kind of changed during the logged time.
Screw it properly together and balance the props.
-then monitor vibrations next time you have it flying.
