Parts 1. The base ine the lower right of the picture might make a good base for a flight stand. Which is probably what I'm going to use it for once I dig out the Frame it'll be attached to.
Parts 2. There's a fair amount of good parts here. Ball Joints, Clip Plates, Bar Plates, a Truncated Cone, Slopes, Brackets, and that 3-Way Ball Joint everyone seems to like.
Build. Kind of awkward, but it works.
Can you build something -- a frame, station, or starship -- right away? Yes. (+5)
Is it below, at, or above the golden ratio? Above. (-10) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? Yes. (+5)
Score: +5 (B+). Don't be fooled by that decent score, this is not that great a set.
