Today I was playing with autonomous Takeoff.
First test was with remote, to see if everything is in order.
The second and third tests went full Auto without any RC control and were complete success.
Fourth test was supposed to be 1Km range flight test at 25m, but the quad-copter just went up, and crashed 70m from launch.
For me, it seems that possibly had mechanical failure on compass fastening (since it is away from apm2.5 because of the motor wiring and currents.)
Could someone check out my logs and verify? Problem is, that there is not much left of the copter to do after crash analysis of the fixture.
Here is the flight path of the crash:
Here is one flight before:
As can be seen from the pictures, something had to happen between these two flights.
Also attached the log from the crash.
EDIT: I did a stupid thing and did not re-check logs I attached. Fixed now.

An interesting finding. After calibrating new compass and everything my copter is unable to maintain loiter with same pids as it was using for flying before.
Hi!
I2Cerror seems to go berserk, but i am not the LOG guy, maybe i misinterpret things.
Normally I2C errors occur, if a device is adressed but not found/responding. Perhaps it's a wiring problem with your external mag?

Ps.: My Condolences for your crash !
