hey fellas, i see this thread is a year old and you've probably got it handled by now. I've been building these with lots of light, sound and up graded parts to sell. i actually spent a saturday doing surgery on a stock set of walls to shorten them up. i then got the idea to duplicate them with silicone mold making material and liquid quick set plastic. they turn out fairly decent.
I also bought just about everything that Shapeways sells for these and have duplicated most of those pieces for my builds as well.
I' just started the first of 5 cutaway falcons i have, short walling those is tricky business. I only knew what pieces needed working, but no idea what each needed exactly. got it figured out now, though, but holy cow!
just putting it out there.
