I don't know what it would cost to ship them here from UK, but these kits really have me intrigued:

Like Skyshark and Red Star, they emphasize flying qualities and lightness. They have a terrific selection and the models look pretty close to scale (I think most of the Wing Mfg kits do not). Unfortunately there doesn't seem to be a U.S. supplier.

Some people really like the Top Flite kits, but I get the impression those folks don't mind fast, heavy planes. I watched an 11 lb TF Spitfire destruct on its first flight and knew exactly what I did NOT want in a warbird. A Hurricane of the same size from Warbirds is supposed to weigh 7 lbs with retracts and is designed for half the power most people use on a TF kit. The Skyshark and Red Star kits also have light wing loadings and look very good.
