This is a real cool looking model. Although it contains no materials, it's easily broken down into sub-parts and they can be assigned their own materials for a more diverse look. I was also able to select the polygons from the window and give them their own material. There's a few non-flat polygons that my programs complain about when loading, but I haven't been able to spot them. (perhaps in the front nose section?) All in all, I'm happy with the purchase.
