I also converted my Futaba radio to a self-centering spring loaded left stick. I just gave Futaba's service department a call and asked them what I needed to pull off the conversion. The guy was nice enough to give me all the part numbers and it was something like 99 cents worth of parts. So quite affordable. The conversion was pretty easy too. I had a reply on the forum to someone asking the same question. I gave a complete run down on the conversion. The thread is here somewhere.

Anyway, it's completely up to you to decide how you want to set the radio up, and what channels you want to do what. If you're not sure, plug a couple servos into the receiver, and see what sticks handle what channels. Pick the sticks that feel most comfortable to you. Some higher end radios actually let you assign a specific stick, toggle, or knob to a specific channel. That's a nice feature to have!
