Anybody care to explain how to control relay 1 and 2 by transmitter using rx channels ?
I am currently using apm plane 3.6 for aerial mapping.
To control the camera -a5100- I use aux1 and aux3 as relay 1 and 2 respectively.
Relay 1 triggering the camera, and relay 2 to turn it on and off.
So far, everything works perfectly on mission. It can shoot pictures and turn camera off after the mission, before landing.
But I want to connect the relay to my tx channel, to check manually the camera function correctly before takeoff.
