okay this has been bugging me for a while and i've kind of given up trying to fix it myself. i shoot mostly walking/hiking stuff so im on the RS3 mini with a Sony ZV-E10 and it's been great except for this one thing ? after maybe 8-10 minutes of continuous use the pan axis just slowly drifts left. not fast, but enough that by the time i notice i've lost my subject. if i do a quick calibration it resets but then it starts again.

i've tried recalibrating the whole thing from scratch, checked the lens weight profile, balanced it like three times thinking maybe that was it. motor strength is set to auto. firmware is current as of like two weeks ago. it doesnt do it on the bench, only seems to happen once its been running a while, which makes me think heat maybe? or maybe the imu drifts? idk im kind of out of ideas and the DJI support page is useless as always

thermal drift on the IMU is a real thing on these smaller gimbals, youre probably not wrong about that. one thing that actually helped me on my RS setup was turning off the follow speed smoothing stuff and setting pan axis to lock mode for the shots where i need it stable. not a fix obviously but kind of a workaround.

also ? is the ZV-E10 running any in-body stabilization at the same time? sometimes when IBIS and gimbal are both fighting each other you get weird feedback behavior that can look like drift. try turning off the camera stabilization and see if it still does it.

ive seen people mention that the smaller RS motors run warm and the axis with the most load will sometimes creep when the windings heat up. the pan motor on these mini gimbals isnt exactly beefy and the ZV-E10 with a kit lens isnt super light. might be worth trying with manual motor strength set a bit higher than auto is giving it and see if that changes anything. auto mode can sometimes underdrive when it thinks the load is stable
