In the gimbal menu on the DJI 4 app (v 4.3.12) we find:
Max Gimbal Pitch Speed

Gimbal Pitch Smoothness
and Upward tilt limit.

I set the Gimbal Pitch Speed at 9. Quit slow. Smoothness on 20.

Why is there no EXP setting for the Gimbal wheel ? Like the EXP settings for Throttle and Rudder sticks ?
If I want to make a real slow tilt I have to move the gimbal wheel like a tiny tiny bit and the move starts. It listens so narrow that it is nearly impossible to make a real slow tilt smooth.
I would like to set a EXP on the Gimbal wheel to use more movement and to use the capacity of the wheel.

I hope this will be in a future software update.

Is it so that it was there in previous versions of the DJI GO 4 app ?

I also think the gimbal would benefit from an EXP adjustment. A feature to come in future releases perhaps?
