So, Saturday morning I re calibrated the compass... Then I went for a fly... Take off was normal, switched to POS Hold and flew out over the field. I released the right stick to start to hover and climb.. The copter just continued to travel in the direction it was going... So, I pitched back and the copter started to return towards me. Again, released the stick and and she just kept coming... WTF... So, now I am all over the stick trying to get it to do what I want but it just seems to have a mind of it's own... A few violent pitches and rolls and then just starts to fly away... I just throttled down from about 10 feet and let it crash... :| Broke three arms (S900 clone, RCTimer RS900) one ESC and twisted a gimbal arm... Camera, Sony NEX7 had not a scratch... Gathered up the pieces and and came home, plugged into MP and could not connect... Long series of dots and dashes coming from the FC and a solid red LED. I took out the card from the FC and installed into the computer, I could see the files but could not open them. The next day, I tried again and was able to recover the log. Lots of EKF Chk Errors... (See link to log file below) I'm thinking its gonna be a few hundred in repairs... New Pixhawk and compos mod and three new arms and ESC and hope to be able to straiten the gimbal... There seems to be quite a bit of chatter on the APM forums about this type of problem and do not want to go through it again... I suppose a better pilot could have got down with less damage but none the less, it a confidence problem with the FC... Thoughts?
