Hi everyone,

I had a pretty bad crash happen on Xmas eve that pretty much totally destroyed my Quad.

So much so, it has taken until today to bring it back out try and find out what happened.

It was flying just fine in loiter & stabilize mode on the same flight.

I recall having entered 2 waypoints into mission planner at the time for the next test, switched modes and watched it tumble all the way into the ground.

It all happened so fast I didn't have a chance to try and recover :(

Having been totally out of the scene and APM planner use (and upgrades) in that time, I am now having problems trying to find out from the logs what actually happened

Firstly, can anybody offer any assistance from the attached log please and more importantly where do I find some good advice or website that will help me to do the diagnosis myself for next time

I am not just after someone to give me an idea what happened but I want to learn for myself :):)

Thanks in advance

Sean
