DJI Mavic 3 / Mavic 3 Classic Arm Shaft

The Mavic 3's arms fold on metal shafts that also help them lock into the flight position. When a shaft bends in a crash, the arm can feel loose, fold unevenly or fail to lock, and the motor may tilt slightly in flight.

This arm shaft is listed for the DJI Mavic 3 and Mavic 3 Classic in front-left, front-right, rear and set options. The listing describes metal construction. No maker is named; it's sold as aftermarket.

When a Mavic 3 arm shaft needs replacing

• A loose arm or unstable folding.

• A bent shaft after an impact.

• An arm that won't lock open.

• Grinding or stiffness when folding.

Options and pricing

Individual shafts are also sold. The set costs more than buying the front-left, front-right and rear options together, so it may contain extra pieces. The listing doesn't say, so check the photos.

Replacing a shaft requires opening the body around the hinge. Work slowly to avoid damaging the shell or wiring. Afterward, fold and unfold the arm several times to confirm smooth movement and a firm lock.
