OK, so I've got the Channel 8 assigned in the Pixhawk parameters to perform a camera trigger. But, it would seem that channel 8 is not assigned to any switch on the Iris FSTH9X rc xmitter.
any suggestions on how to assign channel 8 to say the "Gear" switch? I've downloaded the manual for the xmitter, but its not understandable as translated.
thanks for any help.
