Good Gawd, what a beast. Superb job Taz.
Say, what reference material are you using, ie tech manual or blueprints or plain photos?
Just photos and counting pixels and converting. Some of the stuff is slightly out of scale, like the steps. They looked good in the 3D program, but look too large when I glued them all on. The front cage part that supports the front of the gatling gun (M61) is too thick, but I think I will just leave these inaccuracies.
