DJI MINI 4 PRO REAR ARM (LEFT)

The left rear arm of a DJI Mini 4 Pro is one of the four folding arms that extend from the drone’s body. It houses the motor and propeller on the left rear side, and is essential for balanced lift, stability, and proper thrust during flight. If this arm is cracked, bent, or broken (e.g., from a crash or hard landing), the drone won’t fly safely and needs that part replaced.
