My best was a collection planes from the Wright Bros. Kittyhawk up to Jafo's favorite, the F-105. They were 72nd. scale and at one time I had 100 of them hanging from the ceiling in my room.
I didn't have that many, mainly cause i focused on bombers. I had at one time an enitre wing of B-52's hanging, with no room for any else, except a lone F-4D i snuck in there. (Phantom being one of my favs)
I had three favorites...ME-109...P-51...and a FA-18 Hornet.
Loved building stangs, only slightly more than i loved building P-47's!
I still build, i have the british V bombers sitting here looking at me waiting to be painted.

I'm gonna go cry in a corner now
Uh-huh...did that the moment my fellow Aussie posted this little gem.
