DJI Air 2 / Air 2S IMU Module

Owners and shops with both a Mavic Air 2 and an Air 2S can stock one IMU module for both, according to this listing. That makes it a useful spare for a mixed fleet, and at about sixteen dollars it's a reasonable part to keep on hand.

This IMU module is listed for the DJI Mavic Air 2 and DJI Air 2S. It monitors acceleration, orientation and motion data for stable hovering. No maker is named in the listing, so it's an aftermarket part.

Air 2 and Air 2S IMU problems

• IMU errors that remain after calibration.

• Abnormal drift or tilting in calm air.

• Unstable flight after a hard landing.

What to know before buying

Confirm your fault with an IMU calibration first; many warnings clear that way. The listing recommends professional installation and IMU calibration after replacement. Mount the module in its original orientation, since it measures motion relative to the drone's frame.

After calibrating, hover low before flying normally. If drift continues after a new IMU, check the propellers and motors for damage too. A sound IMU keeps either drone stable and predictable in the air.
