Sizewise, and for sheer presence, it'd have to be the F16.
(The others I have are the Blackhawk, Apache and Kiowa Scout helis and the F18). Since I don't have much talent when it comes to repainting, they're gonna stay that colour for a while. And with a significant contribution to the "boogered plasticard" mountain from my attempts to accurize the ChapMei 6-wheel APC thing, I'm not likely to start remodelling the hardware any time soon, either!

Hustler? Yep, that'd make a nice subject but a bit limited on possible colour schemes. Weren't they all just bare metal with black serials and black-and-white stars? (What's the right name for the 'star and bar' national markings? The RAF have the Roundel, but is there a proper name for the American equivalent?)
Given the difficulty in getting relatively small aircraft to market though, I suspect you'll need one of the specialist model-making companies to get one of these (or a bit of D-I-Y?). From a shape perspective, the A10 is a pretty basic form to mould so the complex curves and shapes on the Hustler would give the mould-makers headaches - and that's not even thinking about the size!
Just my 0.02Cr's-rorth.
