I'm almost done building Bumblebee. Just need to glue a couple of parts in the mid-section. Oh boy, that model was a toughie. I had to tie it up using a nylon to help it stand as it's too heavy because I used the 220 gsm card stock. Bumblebee stands at about 16 inches tall as opposed the EX-S Gundam, a model that I built almost two years ago which is 17 inches high. I love building big and complicated robots. I might build Skip's Bumblebee Camaro which I believe is of the same scale as this robot when I find time.
