Do it off ch. 6 It's a 3 position switch, right? I removed the switch on my vanguard and installed a potentiometer from an old conquest I had laying around. I don't use it for a camera, but I like it for the flapperons.
OOOOh ... I didn't think about it till just now, but it might work if you could run a Y from an aileron servo...
I wondered about running the camera off an aileron servo. The camera would look the way the plane was banking.
Is that three position switch a switch with three resistors, one on each contact? I haven't had mine apart before. That's a good idea though.
