Started gluing little pieces on tonight. As Graham noted...some fit tight and do not gluing at all. I feel a few require just a drop of glue in the screw hole. Some of the really small ones are a bit tedious, but that could just be that I'm tired. Anyway, A sharp hobby knife and a little patience is all that is required. The parts all fit very, very well. You cannot tell were not put on at the factory once they are on. Might start panel lining tomorrow or Monday...
And as far as I can tell the rail guns do NOT go all the way forward which kind of bummed me out also, you CAN slide them past the last tab, but then they point up slightly, BUT they do face straight forward. I don't recommend this as I do not think Yamato intended for them to go all the way forward.
By far the HARDEST thing is extending those front four spikes. They pull out in pairs by the way. BE careful pulling those out, or you WILL damage the plastic. They are really in there tight!
