DJI Mini 4 Pro Arms with Motors

On a Mini 4 Pro, each arm and its motor come as one assembly, so a cracked arm or failed motor is fixed by swapping that corner of the drone. The four options cover each position, with front arms costing more than rear ones.

These arms with motors are listed for the DJI Mini 4 Pro in left-front, right-front, left-rear and right-rear options. The listing claims a manufacturing specification without naming a maker, so they're sold as aftermarket.

When a Mini 4 Pro arm with motor is the fix

• A broken or cracked arm after an impact.

• A motor that grinds, overheats or won't spin.

• An arm that no longer locks open.

• Damage to the arm and motor at the same time.

Picking the right position

Front arms are priced somewhat higher than rear arms. Confirm the position by looking at the drone from behind with the camera facing forward. Unlike some listings, there's no full set option, so order each damaged corner separately.

Photograph the motor wiring before disconnecting it, and route the new wires the same way. After fitting, fold and unfold each arm to confirm it locks, then hover low and check that the drone holds position steadily.
