Joe, I'll tell you how I do it on my Futaba 9C and 10C. I'm guessing that the setup would be near the same.

I set both channels to 100% travel. I make sure that there is no expo or rates set, I then use individual sub trim to center the servos. From this point, I make all of the mechanical linkage setup adjustments. Once things are mechanicaly centered and the servo to horn ratios look right and I'm getting the throws I want, then I go back to individual end points and set up for the maximum throw I want. At this point both servos should be moving equally. If it is setup correctly, it doesn't matter if you swap channels when you plug in the servos. They will be matched. From here, I setup expo and high/low, or with the case of the 10C High/Medimum/low rates

Any sub trim you use has to be on the individual servo and same for end points. Once you get that seup in the begining, don't touch either or you are back to square 1

Hope this helps.
