Ghostrider, Chris, per your recommendations here, I purchased a FrSky decoder with S.bus on one end, and four individual PWM outputs on the other. However, I have spent the last couple of hours to program the decoder per the instructions, and no matter what I do, all four outputs are tied to channel 1. As a first step, I'm just trying to get it to use channel 3, then I'll take the next steps to get the four outputs to be channels 9-12. My intent is to do what you suggested so I can easily change my 2 person S800+Z15 setup to a 1 person for some simple flying tasks. Any suggestions or tips since it sounds like you have both programed these decoders before?
BTW, I'm using a R6208SB, and the following FrSky decoder:

To further explain what I've done:
1) Connect Sbus side to the receiver, power them both up, press the button for selecting the output until #4 is lit up.
2) Connect the #4 wire of the decoder to the R6208SB output channel #3 (trying to get that wire to output as #3).
3) Powerup both units. I see the R6208RS blink the red LED three times as the instructions said it would.
4) Powerdown everything. Connect FrSky decoder #4 wire to the Z15 input (I've been using Aux3 to test this), and when I power up the copter, the Z15 Aux3 signal still tracks with channel 1 instead of channel 3.
I've tried multitudes of variants of the above sequence, sometimes with the Sbus decoder input connected while programming, other times without. I've tried the decoder wires 1-4.
Any ideas of what I am doing wrong?
