RE: 1/4 scale SPAD Fokker D-VII
I might add that D7's aren't the hardest WW1 to balance but keep in mind they usually build tail heavy with wood, I assume you will have a similar challenge.
I sure am glad to see someone building planes that I was always curious about trying. I really hope this works out well !
I haven't checked your link yet. If you stop back here would you let us know which plans you might be using for your outlines? I built a 1/4 D7 Balsa usa last year. Was wondering if thats what you had for plans....
