Shaun,
I've seen your work on brickshelf before and I am just
floored by the detail. You are, by far, one of the
best lego modelers out there.

Your attention to detail is clearly seen in the beautiful
re-creations of WWII and Star Wars machines.
I have created modern day chopter sorta modeled after
the UH-60 Blackhawk. Two versions exist:

Extended version (more cargo space)

Enjoy,

| Hi All, I've uploaded some pictures of my latest MOCs - a German K5 Leopold 28 cm Rail Gun, a freight car to carry the ammo, and a flatbed car carrying a Sd.Kfz 250 Halftrack. The flatbed car is pretty self-explanatory. It can be found here: (URL) (...) (25 years ago, 28-Apr-01, to lugnet.trains, lugnet.build)
