DJI Mavic 3 Series Gimbal Roll Motor

A leaning horizon on a Mavic 3 can have three causes: a calibration that's drifted, a bent gimbal arm or a failing roll motor. Only the last needs this part, so it pays to rule out the other two before opening the gimbal.

This gimbal roll motor is listed for the DJI Mavic 3, Mavic 3 Classic, Mavic 3T, Mavic 3E and Mavic 3 Cine. The listing gives no maker, so it's sold as aftermarket.

Roll-motor faults on the Mavic 3

• A tilted horizon that gimbal calibration and the horizon adjustment can't correct.

• Side-to-side wobble or abnormal noise from the roll axis.

• Gimbal motor overload errors after a crash.

• Grit or stiffness when the roll axis is turned by hand with the drone off.

Calibration, arm or motor?

Start with a gimbal calibration on a level surface. If the tilt stays, inspect the roll arm for bends against a straight edge. A straight arm with a rough or noisy motor points to the motor itself.

When fitting, protect the flex cables and keep track of each screw. Calibrate again and record a test clip, checking the horizon at both ends of a slow pan. A healthy roll motor holds the horizon level across the Mavic 3 models named.
