Richard,
I'm planning on someday putting mine in a 1/10 scale F-2A Brewster Buffalo, plans by Jerry Bates. Wingspan is 42" and Jerry offers a beautiful fiberglass cowl and crystal clear vac form canopy for the plans as well.
You can go to his website at
www.scaleaero.com/jerrybates.htm
for more info and current pricing.
In the short run, I'm thinking of getting a Great Planes Piper Cub and marking it as an early L-4 Grasshopper. Might even mark it as a Dutch bird that the Germans captured. Imagine a cub with black crosses and swastikas? You won't find that one at too many flying fields.
Hope this helps,
Brian
