Handy little tool. Scale Conversion Calculator Working in 1:48 scale it's pretty easy to figure out the conversion from real life to scale, ¼" = 1 scale foot. I like to work in metric so when I went to check the distance for decal placement from the wing-tip the illustration showed 22", just under a ½" in scale. Using the converter it showed 11.64mm.
Posting this again, this is a website for which I do the technical side, server maintenance, css etc. It from the "Stichting Fokker G-1". We're dedicated on digging up as much of the history of the Fokker G-1 heavy fighter. 2 books were written which are now the standard works on this fascinating fighter. The next goal is still to be able to build a flying replica. Anyway, we got a translated page now, so enjoy: Fokker G-1
