I´m having one problem with my gimbal, when i rotate gimbal for down the drone rotate for right, anyone help me?

It's a weird problem those controls should be totally unlinked from each other. Not even sure what you mean. Are you sure of not inadvertently pushing on the stick while you move the wheel ?

You have tried to do an RC calibration ? You can see the input from your MD screen and verify everything is working correctly, and also notice if the control wheel has any effect on the stick controlling the altitude/yaw (default mode 2: left).

Calibrate the remote controller

Hello there brunofilipe15. I am sorry for the trouble this has caused and thank you for reaching out. May we know if your DJI Mavic Mini had a hard landing or a crash before this issue happened?  As A J posted on post #4. Kindly please try to calibrate the remote controller of your DJI Mavic Mini for us to be able to isolate the said issue. For reference I will post a DJI tutorial video on how to calibrate the DJI Mavic remote controller. Thank you.

I found the problem.
The button of gimbal down are sending signal to the button turn left and when i put gimbal up button turn right are sending signal.
