[QUOTE 1666251, member: 45"]I don't see how that works, given the picture.
Normally they're-
Channel 1 - rotor power (up/down)
Channel 2 - differential between upper and lower rotors (left/right)
Channel 3- vertical facing rotor on tail (tail up and down - forwards and backwards)
The one in the pic has a horizontal tail rotor (turn left/right) and twin main rotors. I'd be interested to know why as they both serve the same control function, and I'd also like to know how it does forwards/backwards.[/quote]
Mine had the horizontal rear rotor, spinning one way it would pull the tail up and cause the helicopter to fly forwards, and vice versa.
I think (probably wrongly) that the multi channels are needed for collective pitch helicopters. On those, as well as throttle, you can alter the pitch of the rotors which is how they can invert and pull of those incredible stunt maneuvers (google 3D RC helicopter to see what I mean)
