I have two copters that I wired up the same and one I have the camera switch working on rc8 by using rc8_function = 1
On my other copter which has 3.5.1 I have more channels so naturally I want aux 1 (rc9) to be the switch but there is no rc9_function. I checked on RC8 and there too is no function to set it to passthru
How do I set RC9 to passthru out on aux 1 when I have no rc9_funtion?
