10 channels is enough Rocketman. However, JR did this incredibly dumb thing (in my opinion). They set channels 9 and 10 so that they can not be computer mixed with any other channels that you want to run at the same speed! You can't put one elevator servo in channel elevator and one in channel 9 or 10. The one in channel 9 or 10 moves at half speed.

So I put mine as

channel 1 throttle
2 ailerons Y'ed
3 elevator
4 rudder servo
5 gear
6 flap 1
7 elevator 2
8 flap 2
9 wheel brakes
10 The steering servo

Come to think of it, I may have to upgrade to that fancy transmitter you've got Mark. If I get heavy into 10 channel airplanes or better, the matchbox could get expensive. Still hope someone comes up with a programming solution.
