Thanks for the input guys.

I will probably be building the "sport" wing version as I have heard you get bored with the trainers easily. I just got back from my LHS, and the guy there showed me a Hangar 9 P-51 PTS. If I would've survived the wife after coming home with that, I would have. Although, I think I was just excited about seeing that thing. I still want to build my own. There's just something about it. My plan is to start building, and get the engine and radio, etc as I need them. I don't know how long it will take me to build, and that way I can spread the cost out.

The radio says it's brand new, but if I do get that one, then if I need more than 4 channels, then I'd have to get a new radio. So I'll have to think about that. I'm not too concerned about the engine, although, the better one is only a little more. I figure I'd just buy a new one when I built my next plane.

About the radio: What would I need a 5th channel for? I can think of landing gear, but what else? And, do I need to be concerned about the frequency?
