I started from scratch a few years ago with measurements on a real Draken. Several hundred photos and a nice friend holding a yardstick finally gave that I had all sizes and dimensions documented. From there I used a CAD-program to build a digital copy of Draken, scale 1:12.
All wood parts of my Draken kit are CNC-milled, the building documentation contains 56 (english) pages, six drawings are included and the fuselage (fusoliera(?)) is build in a CNC-milled jig (which ensures correct shape).
It has been really fun to make and produce this Draken kit and I get to know a lot of nice people around Europe.
I´ve now started with another, Swedish, jet fighter and it will be ready for "take-off" within a few months.
Please look at below attached link. It shows a building log from two builders in Sweden. Use googles translate tool to change language from Swedish to Italian.
