RE: !/4 scale WWI kits?
Duncan does not makes kits any longer. It's been several years since he stopped production due to health issues dealing with the fiber glass parts. I built his SE5a and its very scale in most respects. One issue I have is his wing mounting methods. I prefer the full scale practice of brackets to hold on the wings in stead of the metal rods. What happens is that you get an irregular joing at the wing/fuse.
I like the Hanriot. I wonder if it's construction technique is the same as the SE5a.
