Jet and Warbird advice
As i mentioned, look through the Top Flite or great Planes catalogs. they are some of the best kits out there. Sig too!
Sig make one of the best '2nd planes' called the 4 Star. the have three sizes, so one is bound to fit your budget / car. As for warbirds, you might want to think of some of the 'trainer' types before thinking of the fighters. The Cub is a great example, as with the PT-19.
Curious, you've picked all American warplanes.. what about a Spitfire, the ever popular FW 190 or even the ME (BF) 109?
I've done a Great Planes Super Sportser in MiG 3 'winter' colors. It looks 'close'! [img]i/expressions/face-icon-small-happy.gif[/img]
