Bem, with all due respect, the bottom line regarding pattern models is not the pretty finish and countless hours of rubbing the finish until it shines back like glass. There's a large associated cost with those hours. It's beautiful to look at, agreed, but not an F3A or AMA requirement.
Some of the stuff I've seen from TopRCModel and Xtreme Compsites is quite accurately built. And is very lightweight. Finish is just okay and not to the Oxai extreme, but plenty adequate for flying.
Ours is a flying event; I'm sure you know that. Frankly I never understood why anyone would pay so much money to buy the real expensive models available when much less expensive choices that flew at least as well were available. And I'm not talking about the dozen of us left that still build our own.
