Hi Greg,
While I'm not (yet) a scale competitor, I have hung out at the NATS and especially local scale contests. What you were talking about doing is what I've seen a good bit of done locally and even at Brodak's in "fun" or Profile scale. Getting started is the "Big" thing, and learning the 3 line system of take offs, taxi, landing, etc., might just be easier with that Brodak plane.
Of course, as you go up the food chain, you will have to get much more "scale" in your builds.
