First, welcome to the forum and second welcome to the GB's. That's a bugger of a kit but I've done a couple, like Terry and Andy mentioned, I built my first one over forty years ago, and like Glen and Geo mention I have three Hobby Craps in the closet and two of these as well as one Hasegawa and four Tamiya, Three guess and the first two don't count on which are going to be built.
Your doing a bang up job on this at time difficult kit. I like the Kosters gear bay. The really nice thing with this kit is it can be built as so many variants, and it's inexpensive, well until you start buying all the updates.
Great work and hope to see a lot of you!
