So I was flying the Phantom 3 Standard last week and it wasn't hovering at all, just  veering off.  It veered off and it hit my car.  Not hard but it stopped  the propellers from spinning.  Now whenever I try and fly it, the gimbal  is constantly clicking, the camera is always at an angle, and i keep  getting "gimbal motor overload" error showing on my phone.  I have done a  lot of searching on Google.  I did a gimbal calibration twice, I did an  IMU calibration twice, and I even removed the 5 tiny screws and the  back plate off the camera and looked at that rod with the flat side.  I  verified the rod flat side was already lined up with the camera, so that  was not the issue.

What really worries me is that this drone is not mine, it is my boss's  he lent to me to learn how to fly and teach him.  So I want to get this  fixed ASAP.  I am willing to buy a new gimbal if that is what is needed.   I just want to get this fixed.  I would appreciate any help or advice.
Thanks!

In a jam, aren't ya? I can sympathize. Could be one of many things. Is camera still working good? Check grub screw at top of yaw arm first. make sure it's tight and on the flat shaft.  Second, loosen cover on yaw motor and check that the shaft is sitting level.  Tell your boss you're gonna test a while longer lol.
