DJI Mini 3 Pro gimbal flex replacement

Fix shaky footage and gimbal overload warnings by replacing the creased yaw-arm ribbon.

Safety first — Medium risk

Battery cells and small glass parts. Disconnect power before working and never bend or puncture a cell.

Tools required

Power on with the gimbal unlocked and watch which axis stalls. A yaw stall with intermittent camera signal is the classic creased-ribbon signature.
