What is the 10th channel used for? I'm just trying to get a non-biased view on this radio over the others. To me it seems most people choose the 10x cause it's easy to program has a 10th channel and they are partial to JR. I would like to see past these and get to the details.

The fact is if we had 14 full channels available some of us would use every one of them. So choosing the 10 channel radio is almost a given for most of us. A good example would be my Bob Cat. BV originally designed the Bob Cat to be flown with a simple 6 channel radio. Well, I am out of channels using my JR10X----
My setup for the Bob Cat is:
Throttle = signal channel Jet Cat 120 turbine operation
Aileron = Left aileron
Elevator = routed to a JR Match Box so I could match up elevator throws ----- the elevators on the Bob Cat are split so to match up throw you must use two separate channels or use the match Box or match program using multiplex or hitec servos.
Rudder = Controls one of the two rudders
Gear = Controls air retract system for all three gear
Aux1 = Controls the right aileron, I setup using the Flaperon function
Aux2 = Channel for controling gyro gain, gyro used on one rudder and nose wheel. Note I want gyro help on nose wheel because BV's wheel brakes have a tendency to pull left or right ---
Aux3 = Controls the servo for the wheel brakes
Aux4 = Controls the left rudder and is driven by the rudder channel. Also is coupled with the same gyro used for nose wheel, the gyro is a dual output type with a gain control (Aux2) By coupling the gyro to at least one rudder I thought I could get some rudder stabilization for the Bob Cat wiggle-----and it seems to work well enough.
Aux5 = Controls the Right rudder is driven by rudder channel.

Now most of you are probably wondering why I used up three channels just for rudders and nose wheel when one channel would do the job! That gets to the crux of the question why use a 10 channel radio? I never have enough channels, if nothing else I will split a channel add two servos for redundancy only. In the case of the Bob Cat I wanted to experiment with Crow / butterfly of the rudders OUT to see if they alone would help with the wiggle and maybe at the same time add a little more drag for landing setup ----------I have found that in fact they do help on both counts. I just wished I could split them more drasticly as of now I can only Crow them out about 3/4 inch -----helps with drag and wiggle but I believe say 1" 1/2" Crow would be much better.
