There aren't instructions with these models, BUT - click the very bottom link on the page (taking you to
ペーパークラフトで作るヘリコプター) and at the bottom of THAT page it says "How to build (by Japanese), and a link to a blog/forum
????????????? - Yahoo!??? where on the left there are links to pages where there are build photos. Luckily the links have the model names in English! Amazing what you can find when you try!
