So I have never had any issues with my Phantom 3 Pro before, but the other day I was at the top of a hike and bringing my P3P back to me after getting a few shots. I was on a fairly tall rock and the P3P was below me as I was pulling it back home. When it got very close to me, I let go of the controls to bring it to a stop, but it kept charging and ended up hitting the rock and (luckily) landed on top of the rock instead of falling to the ground. After a few checks and inspections, everything seems to be running fine... except when I turn on the drone for a flight, the gimbal goes through its range of motion test and then slowly slides facing a few degrees left (left when facing the camera lens). The camera then stays in this position, which when in flight will reveal the left landing gear more often than desired. Even after calibrating the IMU in a wide open area, several attempts at gimbal calibrations and compass calibrations, the camera points left about 10 degrees. I have also tried tightening the yaw are set screw and realigning the yaw motor shaft. I have watched several videos online, but nothing seems to work. I can't find anyone else getting the same issue too. Any ideas on how to reset or adjust it? Or am I going to have to replace the whole yaw motor? I haven't found anything that DJI has given me to recalibrate the yaw setting of the gimbal or adjust it.
