Are you planning on anything fancy like a Hanger 9 Ultra Stick Quad Flap setup?

If not, then try this:

1) (2) Airlon servos on the right wing Y-connected to channel 1.
2) (2) Airlon servos on the left wing Y-connected to channel 6.
3) (1) Elevator servo connected to channel 2.
4) (1) Elevator servo connected to channel 8.
5) (2) Rudder servos Y-connected to channel 4.

A) Activate the FLAPERON function in your 9C
B) Activate the AILEVATOR function in your 9C (0% for airlons)
C) Be sure you match your rudder servos before installing -- this is easy to do if they are digital and can be programmed (Hitec)
D) As with C above, be sure each pair of airlon servos are matched.
