I am trying to use three of the auxiliary ports (ch9-ch11) on my Carrier Board to control the signal to my pitch, roll, and yaw of my gimbal. I said servo9_fuction, servo10_fuction, and servo11_fuction to pass through. And assigned the appropriate sliders at my radio to each individual corresponding channel. After Setting these configurations I am not getting a signal through the auxiliary ports to control the movement of the gimbal. What am I missing in the configurations of Mission planner in order to get this to function?
