The BD-7 was developed in the mid-1970s as the follow-up to the BD-5. It was a four-place, home-built, aircraft and incorporated many of the aerodynamic features of its predecessor, making the BD-7 quite advanced for the time. The fuselage utilized the BD-5’s all metal body, while the wings used the BD-4’s tubular spars and all fiberglass panel ribs in its construction.
