PHANTOM 4/4PRO Yaw Motor Disassembly
Whether you replace the yaw motor with a newer or older style unit; to properly center the gimbal with DJI’S original manufacturing placement of the motor’s sensors and the housing’s magnets in conjunction with your P4/P4PRO, you must swap the replacement unit’s inner motor sensors, into the original unit’s outer magnetic housing.
If you do not swap the inside components like this video shows and you only replace the full motor unit, afterwards you may then still have to send the P4/4PRO into DJI to recalibrate and recenter the gimbal.
The P4 is the older housing shape and the P4PRO is the newer housing shape, but both inner motor sensors are the same and are interchangeable.
The motors must be replaced if the motor’s sensors are scratched by the housing, due to the motor unit buckling on itself in a crash.
