Couple of days ago my quad crashed in a way i could never expect. I was flaying for couple of minutes when i saw some warnings on my laptop like "Bad compass health" but i continued flying.
When i was close to my launch point, quad automaticly swiched mode into "LAND", I changed it into AltHold, then RTL to see if GPS is functional and after 30sec or so quad just disarmed in mid air and crashed from 30 meters.
I know that i should avoid any warrnings and resolve them immediately but APM should NEVER disarm in mid air right?
So could any one help me understand what happend? I'm attaching my logs from APM and my GCS.
For what i can understand the "ERR:EKF_CHECK-2" and "ERR:EKF_CHECK-0" has something to do with it but could it disarm my quad?
Thanks for any help :)
