DJI Mini 4 Pro Rear Left Right Hinge

The left/right hinge (arm hinge or pivot hinge) on a DJI Mini 4 Pro is a mechanical pivot joint that connects each folding arm (left or right) to the drone’s body. It allows the arms to fold in for transport and fold out securely for flight, and keeps them firmly in place once locked. If this hinge gets damaged (e.g., in a crash or hard impact), the arm can become loose, wobbly, or detach entirely — affecting flight stability and safety.
