Crash log. Mechanical failure?

Hi,

I am a total beginner with APM and have had a lot of fun playing with this stuff!

My quadcopter has been behaving ok until yesterday when I had a hard crash from 25 meters tunneling down. I have a first person youtu.be/QFWOBg6-Tlk. Now I am trying to understand what the problem was. In my logs I see a big difference between Roll and DesRoll. Is this an ESC problem? After the crash one the connectors to one of the motors was broken but this could also be a result of the crash instead of the cause. I attached the logs.

Is there more to be learned from my logs?

It could be but hard to say for sure. Might have been more obvious in rcout was being logged too.

for the next flight…ill log everything.
