It was marketed for homebuilding in plans or kit form, with over 350 sets of plans selling by 1978. The BG-12 is a conventional sailplane design, with a high cantilever wing and a conventional empennage. Later models featured a highly revised fuselage, a swept-forward tail fin, and an all flying tailplane with balance tabs.
