Hi all,
I built a quad with a dji flamewheel f450 frame and the pixhawk and it all flies normally when in stabilize and alt hold modes. However when I tested RTL mode it went up to altitude and flew in a curve past home not passing over it at about 30mph and then crashed into the ground. An auto analysis of the log came up with this:

Somewhere in the chain of events my gps mast broke and my battery and 3dr power module seperated from the quad… I was told before it could be my HDOP… Also when I fly in loiter mode the quad drifts rapidly away at app. 20 mph+. The log files from the incident are attached.
All help is appreciated,
