Hi All.. first post 
Just tested my newly built quad at my mates place - because he has a large garden surrounded by high trees.. Maiden flight for both me and it - and a great place to test it 
........... or so I thought 
All was well with my intended low flying test (with a couple of bumpy landings that a little trimming of the controls sorted out), then while (I think) pitching back.. all of a sudden it shot up into the air and seemed to have a mind of it's own not responding to my control - fortunately it landed back on earth after switching into RTL. The controls seemed to work as expected otherwise (yaw, pitch etc.).
Result was a broken leg, gps stick, 3xrotors, 1 motor cable to resolder, 1 GPS power cable snapped at connector, Repairable break to frame.
Still - I was so lucky! and I know it! I was in shock after lol - I've had visions of it going wrong racing through my head picturing what I didn't see 
Next time I'll appreciate the power of these things and get somewhere more open!
Anyway, I have downloaded the logs - could anyone interpret them for me to give me some sort of clue about what went wrong? They're attached as a .rar
Also got this out of the APM.....
just got this out of mission planner - still a little unsure of what looks like the problem here...
