My question is, can I use the Smartfly with the Cortex at all, and if so, would I have to seperat the elevator and aileron servos on their own input to the smartfly then into the Cortex?

Mark,
I know Bob already gave you a pretty complete answer but as I recall, since SmartFly provides a very low current regulated separate power supply for the receiver, they state that you should not connect anything to the receiver except the SmartFly ports. Since the Cortex WILL draw power from the receiver, the regulated power supply that SmartFly provides may not be adequate, even though it wouldn't be powering servos directly. I know that people connected a single servo directly to the receiver in a SmartFly unit have had issues because of this. At the very least I would contact the owner of SmartFly and ask him about this as I've heard he is very helpful. I'm correct about this and I'm by no means certain that I am, that would only leave you the option of separating all of the channels and connecting the Cortex between the SmarFly and the servos. To be honest, I don't see any real value to the SmartFly unit in this configuration and if it were me, I would simply tear the SmartFly out of the plane. If you separate each elevator, aileron and the rudder that leaves only the flaps and the throttle going through the smart fly. If you're setting this up on your JR12X, a 12 channel power-rsafe receiver would probably be a far superior replacement for the SmartFly unit if you are adding a Cortex.
