I built that kit, many moons ago...almost 20 years! I really don't remember much about it, other than it was an A-10. I had the AMT/ERTL box that included some figs and ground equipment.
As for the Trumpy A-10....yup...it's huge!
It is not without issues though. Nothing really major, that some filling/sanding can't handle though. I would recommend getting the Squadron vacform canopy...that will give you a corrected piece for just a few bucks (kit canopy is mis-shapen). They give you TONS of ordnance, but it leaves a lot to be desired (shape and detail wise)...I used left overs from Academy's F-18 kit.
