Jules, I;ll have to pick out the exact article on that site discussing what they feel is the correct color fo IJN gray, especially in the early war years... although interlaced with both technical and japanese words it was fairly informative... the link I posted of that model is a pretty close match to what they feel is the "right" color.. (a subject of hot debate evidently) .. just getting that combo of color is going to be the hard part...
--edit--
I liked the lighter coloring of panels on that kit too... I think I may try it... BTW: jules... siunce it sounds lik you rhave the same kit... it goes together ok.. and I didnt find a prob at the wing root... I always glue my upper wing halves on at the root before I glue them to the lower... like that it went on like a charm and has less gap than a lot of kits I have built recently... be careful though, the plastic is a bit soft and it would be easy to oversand a pice and get it misshapen.
The main part I want to sand is behind the pilots head... it's a brace of some sort I am sure for upside down landings... the real AC I saw, the brace is concave, on the kit it is more of a rough triangle shape...
ok here it is... it is a canopy brace of some sort..
