Hey there,
Recently I crashed my Phantom 3 Advanced, the only thing on the drone that broke was the roll arm on the gimbal (specifically, the ring around the roll motor).
After I bought the replacement roll arm part, and before it arrived. I attempted to turn on the drone at home while semi-attaching the broken roll arm to the roll motor, just to see how it was doing and even though the roll motor had trouble spinning correctly (understandly, as the arm was broken), it was indeed able to rotate and center the camera correctly, just like before the crash. This confirms that no sensors or cables were damaged as a result of the crash (because the gimbal sensors and cables were working correctly afterwards)
Now, the replacement roll arm part arrived, I dissassembled the necessary pieces of the gimbal as carefully as I could, replaced the broken roll arm, and put it all back together.
But now when I turn on the drone the gimbal goes crazy, not side to side but as if the camera is trying to look backwards, to one of the max-turn corners it can turn to (most left down or most right down, etc).
I figured one of the motors is not aligned, so I checked all the motors and their potentiometers.
Thanks!
PS. I feel my thread is somewhat related to this one, except in my case I was able to confirm the gimbal was working after the crash, and before the roll arm replacement.

- The yaw motor, on the base of the gimbal is aligned with the flat side to the small black screw and the black screw is tight.
- I checked and aligned the roll motor, made sure the flat side is facing the drone when the roll arm is level
- I checked the pitch motor (the one that directly holds and turns the camera) and I actually wasn’t sure if the flat side is supposed to face the camera’s forward direction (where the lens is looking, to be specific) or the other way around - so I tried both, multiple times, and it didn’t fix the issue.
Thanks!
