That's actually the minor issue.the more serious one is that the gimbal was shaking and swiping and burning like crazy.
Was it the ribbon band or something else?

Have you tried calibrating the gimbal?

Hi, sorry to know you’re experiencing difficulties.
For the APP, did you install the latest version  v4.1.18 (432)?
As for the gimbal, please make sure the vibration absorbing board is hooked properly. Then try to calibrate the gimbal.
May I know how did the issue happen? Did the drone get crashed or any hard landing?
