If I'm understanding your question correctly, there are 2 ways to do this.
The first is to enable Bank Switching on the main VBar screen. On the far right side of the screen, pull the dropdown box labeled "Active Bank Selection" and select Bank 0/1/2/3.
Now, copy your Active bank into the remaining banks. Then, change the gyro gain setting each of the other banks to a different setting.
Bank 0: Gyro Gain 60
Bank 1: Gyro Gain 65
Bank 2: Gyro Gain 70
Now, by using the switch that controls the GEAR channel, selecting another bank will change the Gyr Gain. You can switch banks in flight to immediately see the effect.
Second way is to select "Aux Gyro Gain" in the drop down, and use the values in the Aux channel to set the gain from the radio.
Is that what you needed?
