Just finished my Atlantis STS 132 build from AXM Paper Space Scale Models. It was a really fun build and I'm amazed at how robust it is. I even gave it a toss off of my deck to find it pretty much had a glide like a lifting body. So I started thinking that I would hack the paper external tank and SRBs to make the whole thing a flyable model. Has anyone here tried that?
I highly recommend these Shuttle builds.
