crashed my mavic 3 about three weeks ago, wasnt even that bad of a landing honestly, caught a branch on the way down and it dropped maybe 4 feet onto grass. the gimbal looked fine at first, no visible cracks or anything, but now the horizon is just slightly off and it drifts slowly to the right during longer clips. its subtle enough that i almost missed it on the first few reviews but once you see it you cant unsee it.

ive already done the gimbal calibration thing in the DJI app like four times. it goes through the whole routine, says its done, and then the drift is still there when i fly. i read somewhere that the ribbon cable can get slightly kinked or one of the IMU sensors can shift after an impact even if nothing looks broken. does anyone know if theres a way to check the ribbon without fully disassembling the whole gimbal? or at this point am i just sending it to DJI and waiting 3 weeks

yeah unfortunately with the mavic 3 gimbal theres not a ton you can do yourself without getting into some pretty fiddly disassembly. the ribbon cable on those is genuinely fragile and if its partially delaminated from the impact you wont see it without pulling everything apart. ive seen people try to reseat it and make things worse so just be careful if you go that route.

honestly if its still under care refresh it might be worth just doing a replacement claim rather than waiting on a repair. the drift you're describing sounds like either that ribbon or one of the gimbal motor encoders got knocked slightly out of alignment which isnt something calibration software can fix.

same thing happend to my air 2s after a tip-over on a rooftop landing pad. calibrated it like a dozen times, never fully fixed it. ended up just sending it in, was annoying but DJI turnaround wasnt as bad as i expected, think it was like 12 days total. the drift on video was just too distracting to live with
