Description
Replacement motor arm assembly for the DJI Mavic 4 Pro: the arm with the brushless motor and wiring already installed. Use it when a crash has cracked an arm, torn through the motor wires, or left a motor that won’t spin or throws an ESC/motor error.
Pick the right arm
- Right Front (with radar): carries the integrated obstacle-sensing radar module. Order this one if your right-front arm is damaged.
- Left Front, Left Rear, Right Rear: motor arms without radar.
- Full Set (4 arms): all four positions, for a heavy crash or a donor rebuild.
“Left” and “right” are as seen from behind the drone, with the camera facing away from you. Mavic 4 Pro only. These arms do not fit the Mavic 3 series or the Air series.
Shell or full motor arm?
If only the plastic cracked and the motor still spins freely with intact wires, a cheaper shell may be enough. If the motor or wiring is damaged, you need this full motor arm. Not sure? Send us a photo or a short startup video and we’ll tell you which part you need, free.
Rather not install it yourself?
Arm swaps on the Mavic 4 Pro involve opening the body and routing motor and radar connectors. Mail your drone to The Drone Hospital and we’ll fit the arm, recalibrate, and test-hover it. Our repairs carry a 90-day repair warranty. Get a free quote.
