That's quite right! As you have it set now, you'll use a 6 channel receiver and a heading hold tail gyro (there are many great brands to choose from). Once you do decide to go flybarless, again, there are many great ways to go about it. Some flybarless controllers can use a DSM2/DSMX Spektrum Satellite receiver. You can even go simpler and get the Spektrum AR7200bx...that's a 7 channel receiver and flybarless gyro all in one little unit and I believe that you can also use a satellite reciever on the AR7200bx. There are also many other inexpensive, and yet very effective, flybarless controllers but since we are talking about Spektrum equipment, in the Spektrum section of the forum, we'll talk about the other gyros in other threads.
Please, feel free to continue to ask questions as you think of them. We'll be around to help you out.
