I have my Phantom2+gimbal since last week. I did abt 7 or 8 flights and crashed twice. My P2 doesn't seem to hoover in place. It goes up or down, it drifts in any direction. Not uncontrollable, but unreliable. When I tried to let him come back to the home spot in failsafe mode it crashed in a tree that is at least 5 meters away from the home spot. I calibrated the compass several times with success, I updated the firmware. Nothing helped. Then I figured it might be the remote that needs calibration, I attached the RC to my Mac and launched the RC application and I think I saw a clue. As soon as I hit the "calibrate" button, the AETR values were NOT centred (see attached image). So I did the calibration, and when I finished the positions were on the center spot. But as soon as I hit "calibration" again, the values returned as show in the attached pic... Then I went for a test flight and... it got a lot worse! Immediately after take off the P2 flew to the left and crash right away... Can someone help me out? It is not easy to find good information. The user manual should be at least twice as thick!!
