DJI Mini 4 Rpo Front Right Left Hinge

Front arm hinges on the DJI Mini 4 Pro are pivot hinge shafts or axis joints that connect the front motor arms (both left and right sides) to the drone’s main body. These hinges allow the arms to fold inward for transport and fold outward for flight, and they also lock the arm in place when deployed. If one of these hinges breaks or wears out — for example, after a crash or hard landing — the arm can become loose, wobbly, or unstable in flight.
