Oh sorry. Forgot about that.
Yes, the model is here:

As with many Japanese designers, you sometimes have to jump thru a few hoops to download things
but this site is pretty straightforward.
And you may have to use a translator (I use Google Translate, works fine).
This project took almost 4 years, and he released each stage of the model as a separate download package.
Hence the way the download page looks.
Each download package(PDF) has a full page build tutorial if you click the thumbnail of each one.
(Another common practice among Japanese designers)
When you click the PDF link, the PDF should load and then you can save it to your computer.
All the accessories (aircraft, equipment, etc) came at the end, and are obviously optional.
The model obviously requires printing on cardstock.
He is suggesting normal 65lb cardstock (around 170gsm) for most of the construction.
