This model is 6'2" (74"). It's a lot to work with, but it makes details easier.
Also, Ronin... make it look dirty and grimy :-). I'm thinking about adding some subtle rust to mine after seeing a weathered model... it adds so much to it. After reading about fiber optics, I'm considering lighting it too. The optics would never break or wear out so I wouldn't have to worry about breaking the model open to repair anything.
