Since I need to use Sony RX-100 MIII for your aerial photos, I added Walkera G-3S Gimbal to my S900. In A2 Assistant I can setup automatic Control Gain to 10% as minimum, but the Gimbal overact for the S900 pitch. Example when the copter it pitched 10 degree the Gimbal overact for 30 degree. If the copter is pitch 20 degree, the Gimbal tilt 50 degree. If I could setup the automatic control gain to zero, I believe that this problem could be solved.
Is there any way to setup the gain to zero? Is there anybody else using Walkera 3d with A2?

i have this problem too.

Have you solved this problem?
