How to discover a crash reason - APM

Hello everybody!

I'm trying to discovery a crash reason reading a data log but I'm not getting out the reason, and I am asking for the help of you to find out why the fall.

The data log is attached  and I filmed the flight and fall. 

Thanks for your help.

  • a very clear mechanical failure.

    Not only from the log (plot ATT.Rollin and ATT.Roll from line 13950)   - but also from the sound and video.

    • Maybe some ESC cut by low voltage? 

      • no,  that would look different (usually a huge instability while diffrent ESC's hit such threshold depending on load.)

        - and voltage was not that low

        - decent multirotor ESCs do not use cut-off.

        like john suggested: anything that makes one of four motors fail to deliver the thrust.

        anything between pwm cable, ESC, cables, motor, propeller mount and propeller. 

        • Thank you so much @Andre K and @John, I will mount again and strengthen the mechanical structure of the quad.

    • that is what I was thinking too. Could it be a loose prop or faulty ESC?
