Before I get started... Man, I had a GREAT day flying my Vision with my local RC club. Some great video and pictures and lots of attention from the fixed-wing guys. I was down for about two weeks with camera problems...it was soooooo much fun having having my Phantom back! Anyhow... My Vision has an issue with straight out, stick forward flight. It tracks slightly to the left. Not enough for concern, but enough to make me continuously correct with very slight right input to get it back to a more straight forward orientation. DJI indicates that this behavior may be a compass calibration issue. I calibrate before each flight and the issue persists (360 horiz...360 vert). Can anyone recommend where in the software I can make adjustments to the Vision or Tx to correct this - or is there further calibration I can perform within the software? Hell, maybe this is normal behavior...???? Any help or advice is appreciated.
