RE: What to build for a second kit.
I can't think of any sport scale P-47 or P-40 kits except the Top Flite .60 size birds. I know they aren't 'dead' scale and are considered sport scale (they usually have enlarged tail surfaces for better flight characteristics....hence not dead scale). Dead on or not, they still look great. If you want to start off a little smaller...say .40 size, Great Planes makes a Sport Scale Corsair and Mustang. The Mustang can use retracts, where the Corsair isn't designed for them.
