I googled, and on allposters they have one that has all of the modern airframes.
Another suggestion is that google the manufacturers. We get Lockheed calendars every year due to Bullets job and it is pics of their air frames.
Second suggestion, print your own pics. Make a collage using a poster frame purchased at WalMart with downloaded pics off the internet.
I am not sure why you want every airframe, but honestly there aren't alot unless we get into the nitty gritty....IE AC130, MC130, C130 H, C130J.
~ the difference is more about missions than airframe.
~~ My account is F15, 15E, 16, 22,35,B1, B2, B52, C5, 17, 21, 130, KC/RC135, EA6...and Raimius will tell you have the Helos. Oh there are also T1/T6 and T38s too
~~~ I am 10000 positive that I missed some.
