Yup. The visual appearance of the rudder has nothing to do with how the model flies. If you want a bigger rudder, make it bigger in the editor. Different airfoil? Editor. If you want it purple, than you have to do that in the colorscheme. Won't affect how it flies!!!
I would very much like to see a G3.5 version of the Fokker E-III Eindecker EA. This is one of my favorites. I see there is a G4 version of the E-I and wonder if it could be somehow applied to G3?
