@TC: Yikes, at 1:1700, the 1452m diameter station would come out at 85cm long. Pretty big. I would love to see that much detail but I know that I would never build it. I don't think I could fathom anything larger than a 1:5000 scale station, measuring in at around 29cm wide.
@McHale: There are already a number of Defiant models available - including Ninjatoes' and various repaints, and Zosho's. Easy to rescale and match to the station. Runabouts on the otherhand, would be hell to make so small. :p
