I recently had a first flight with a 3dr 2014 quad frame and a pixhawk, the experience was a little drifty. Took it up for a few and saw it moving away from me and not really responding to the controls so I brought it down and it flipped over on tall soggy grass. No biggie everything checked out. I was reviewing the log files and noticed des roll and roll aren’t tracking anywhere near one another. And the same for pitch which would explain why I felt it wasn’t responding well. This is stock pids too.
Any suggestions, could it be the radio?
