I have the 3DR quad frame with 850kv motors and 10" props. There is something wrong with this copter becuase once it gets to the point of lift off it freaks out see the video. I have downloaded the 3DR params and uploaded them and enabled my LV sonar. I have read the manual over and over and I cannot find the problem.
Here is the log tuning screen of what the gyros did on that moment.
Please find the last log attached.
Any help please.
