The primary appeals of the Smith Miniplane are its small-size construction simplicity and open-cockpit romance, which is a combination that not all homebuilt biplanes can offer. The fuselage framework is a conventional truss structure of welded steel tubing, faired to shape with wooden stringers. As on most similar designs, the vertical stabilizer is welded up as part of the rear fuselage structure. The wings are made from spruce spars and ribs. Several engines can provide the power: 65- to 85-hp Continentals or 100- to 125-hp Lycomings.
