Note:

Our current stock is the MP66 version which was manufactured December 2025. The batch date is printed on the retail box.

DJI made internal changes to units produced from 2026  onward, including a different gyro in the camera (ICM-1469D). Pilots have reported stabilisation problems with those units in RockSteady and Gyroflow. Our stock predates that change.

We don’t open sealed units, so we can’t confirm the internal components of any individual unit. This note refers to the manufacturing date shown on the packaging only. Stock rotates, so check with us if the batch date matters to you.
