this is really starting to annoy me. had the yaw drift issue on my Mavic 3 back in the spring, sent it to DJI care refresh and they supposedly replaced the gimbal assembly. worked fine for maybe two months and now its slowly pulling left again when im flying forward at any speed above like 20mph. its subtle but you definitely notice it in longer clips.

ive done the gimbal calibration multiple times. auto calibration, manual, all of it. no change. the horizon looks fine its just the yaw creep that gets me. im wondering if this is a known issue with the motor in the yaw axis or if maybe the ribbon cable is partially damaged and its giving bad feedback to the stabilization. i really dont want to send it in again, last time i was without it for three weeks

yeah this is a known thing with that gimbal, the yaw motor is apparently pretty sensitive to any flex in the ribbon cable. there were a bunch of posts about it on the DJI forum last year. some people said it only shows up at higher airspeeds because of the airframe flex or vibration at that point, which makes sense if the cable connection is marginal. worth opening a ticket again and specifically mentioning that it was already replaced and came back, sometimes that gets you a different repair team or at least more scrutiny on the cable routing

have you checked if the gimbal port on the aircraft side is seated properly? not the ribbon inside the gimbal itself but where it connects to the body. mine had a very similar drift issue and it turned out the connector wasnt fully clicked in, just enough to work most of the time but losing signal under vibration. took me ages to figure out because it seemed like a software thing. probably not your issue but its a 30 second check before sending it back in
