Pete,
I picked up the Realspace Models Skylab at the 2012 Nats. I was planning on doing a kit review, so I'll post some photos of what's in the box. I'll shoot some piccies tonight.
The instructions leave a lot of questions, and it is hard to decipher where and how some small parts are attached. I'm not a real space groupie, so my only knowlege about Skylab are based on fuzzy memories dating back to elementary school. I tried our friend Google, but didn't get a whole lot of useful photos.
The kit itself will require some deft assembly skills, as the "X" shaped PE solar array is big, heavy, and delicate. Maybe this thing will need to be soldered for strength? That is one skill I will need to learn.
Personally, I am also surprised that nobody has kitted a plastic Skylab kit. I was hoping DML would do one, but their space kits are kind of toy-like.
