Why would you use multiple channels for functions like flaps and elevators? I understand if you are turning ailerons into flaperons but even there you are using two channels for two functions. But if you need two servos on an elevator, what do you gain by utilizing two servos and two channels vs two servos and a Y jack?
With flaps and ailerons on two channels each, and the right transmitter, you can have
> regular ailerons
> regular flaps
> full span ailerons (flaps acting as ailerons)
> crow/butterfly (flaps down, ailerons up)
All of this is often done on the Hangar 9 Ultra Sticks
With elevators on two channels, and the right transmitter, you can make the elevators work in conjunction with the ailerons.
The Bruce Tharpe Delta Vortex has dual rudders. With them on two channels, and the right transmitter, they can be used as 'air brakes'
