Prizes for the smallst,ugliest and most difficult build all in the same model.
A sows ear campaign, an ugly campaign, or an impossible flyer campaign, you would have to be a sadist to suggest it and a masochist to join! The Eindecker is built from aluminium tube and fabric covered. It does not replicate the real Eindecker control system of warping wings so handles fairly well but needs fairly calm conditions to fly as the wing loading is quite low. Actually it needs 30hp to fly not the 26 I suggested. Details of the UK version of the kit here -
Grass Roots Aviation I also like the Dream Classic, shades of Santos-Dumont's Demoiselle.
