For fun I just did the calculations for the difference in size between a 1/32 DR.I and a 1/24 DR.I.
Not really that big. The 1/24 kit is about 2" longer, and a bit more than 2" greater wingspan.
7" x 8.8"
vs.
9.5" x 11.75"
Really, both are rather small kits. Subject matter like this (the DR.I is one of my favorites!) could be made in a much bigger scale IMO.
1/16
I have the Hasegawa 1/16 Sopwith Camel "skeleton" kit and that is quite large!
