Today I tested my quad for the 1st time with the Pixhawk FC. I use to fly with DJI. I followed the "first flight" instructions and took off in Stabilize mode. All went well: good response, directions were as they should be. Only I noticed that the quad was hovering with throttle at 35%. I adjusted Throttle Hover setting down to 390. That went well: hover at 50%.
I continued testing in Stabilize mode, checked vibration values (seems to be ok), adjusted Climb Sensitivity to 0.64 and RC Feel Roll/Pitch to 95.00.
Then during hovering, I switched from Stabilize to Loiter...: the quad started to drift toward the left. Just as someone commanded a Left Roll input. Trying to correct it didn't help and as I was hovering only 1 meter above the ground, before I realize what was happening the quad tilted further and kissed the surface. Luckily, the location where I flew was covered with high grass and somewhat took some of the impact. It didn't prevent one of my 15" carbon fibre props to break.
As I have no idea what caused this "fly/drift away in Loiter" I hope one of you can analyse the attached log file and explain me what happened. 2014-11-01%2012-17-28.log (i believe this is the Log file when it crashed)
2014-11-01%2011-51-26.log (log file of quad in Stabilize mode: good behaviour)
Any help is appreciated.
