I have a Phantom 4 Pro V2.0 and it doesn't fly straight and the yaw drifts. I have seen that many have had similar issues, but I don't think they match this exactly. Here is a video that I took. I did a voice-over, so you will need to turn up the volume. I do not have a warranty, so I can't send back to DJI. Any help would be much appreciated.  I have calibrated IMU, compass, and sticks.  This forum will not let me attach the flight log data files.
