Laer,
There are two ways that I know of to use a "real" radio. One is to use the Futaba to emulate the Tracon, the other is to use the Futaba solely to control the heli.
The FAQ refers to using the clean acro mode - and this refers to using the Futaba to emulate the Tracon.
So the next step depends on what you want, but following the FAQ is probably a good next step as they've already done all the work, all you have to do is follow along.
Using the Futaba solely to control the heli doesn't have a FAQ, but I think I've shared enough tips so that you can string them together to get this to work. I'm not sure if the FAQ's channel assignment will work in the scenario to "solely control the heli", you'll have to try it.
