DJI Mini 3 Arms Replacement – Front & Rear Motor Arm Assemblies
The DJI Mini 3 arms house the drone’s brushless motors and propellers, playing a critical role in stability, balance, and flight performance. Each arm connects directly to the ESC board and main body shell, carrying both structural weight and motor wiring. Crashes, stress, or wear can easily cause the arms to crack, warp, or break at the hinge points — making them one of the most commonly replaced parts on the Mini 3.
Replacing damaged arms ensures proper motor alignment, smooth propeller function, and stable flight control. These OEM-grade arm assemblies are designed for a perfect fit with the DJI Mini 3, restoring your drone to factory performance.
Common Reasons for Arm Replacement:
-
Cracked or broken arm hinges after impact or crash
-
Warped or bent arms affecting propeller clearance
-
Loose or unstable motor mounts
-
Worn-out folding joints from extended use
-
Motor wires damaged inside the arm channel

Why Replace the DJI Mini 3 Arms?
A damaged or misaligned arm can cause motor errors, unstable flight, drifting, or vibration. Replacing the full arm assembly is often easier and more reliable than attempting to repair cracks or bent mounts. With new arms installed, the Mini 3 regains its aerodynamic balance and durability, ensuring long-term safe operation.
Installation Notes:
Arm replacement requires partial disassembly of the shell and soldering the motor wires to the ESC board. It is recommended for experienced repair technicians or skilled drone hobbyists. Once replaced, the drone will fold and fly as smoothly as it did out of the box.
