Shawnusa,
I was in the same boat a few years ago when I decided to turbinize

I got a JR 8103 8 ch with a 950S 10 channel receiver. Now after a year of turbine flying I whish I would have gone to the 10X right away as I am wanting to add smoke to my Roo and I am out of channels on the TX.

2 channels for wings
1 channel for rudders
1 channel for nose gear steering and gyro (diddn't want gyro on rudders, also makes trimming the nose gear a lot easier, just move the trim tab and the wheel trims but the russers do not)
1 channel for throttle
1 for retracts
1 for airbrake
1 for wheel brakes

So you see I whish I had just one more channel or maybe even 2. 1 for smoke and if I had another one I could use a crow mix on the rudders to have them both go out on landing. Wouldn't probably do much in the way of drag but it wold be cool.

Do yourself a favor and get a 9 or 10 Ch radio. It sucks to be 1 channel short
