I fly my 'Roo on a Futaba 8U just fine. I use the following allocation (i forget the actual channel numbers):

2 channels for elevons (would be 1 channel ailerons 1 channel elevators on non-delta aircraft).

1 channel for rudder

1 channel for throttle

1 channel for retracts

1 channel for speed brake

1 channel for wheel brakes

1 channel for turbine control

I'm going to use the same radio for my Panther, but that adds 2 sets of flaps and speed brakes to the mix. For that, I'm going to use the channel expander from JR to control the flaps and speed brakes from the same channel.

I find with all that going on, I don't really want yet another switch to activate - better to gang them on a single switch/slider/knob to cut down on operational complexity. True I don't have any additional channels to do things like setup the nosewheel steering different than the rudder, but there are other ways to do that, either with an after-market electronic box, or simple mechanical setup - just like in the old days...
