I had a small crash 5 ft up going slow flew sideways into a tree I could not see.  Nothing appeared damaged other than prop scuffs which I replaced. Gimbal was out of whack. I auto calibrated gimbal several times went back up and it looks fine then start to yaw and horizon goes off  tilt again - I manual adjust and it holds for awhile until I make another yaw move and drifts off center pretty bad.  I have refresh but I hate to send this in and possibly have a long wait on repair if necessary.  Any suggestions on how to get my gimbal stable again without issues? Thanks for any suggestions

Have you tried calibrating the IMU as well??

yes twice -- i just made some manual adjustments on yaw also look like its fixed but havent tested it out in big open area yet.  I just hate depending on manual gimbal adjustments.  Hope they stay locked in so I dont have to do it everytime I fly?
