Few homebuilts weigh less than this VW-powered mid-wing model. The Troyer Sportplane weighs only 306 pounds empty. Oddly enough, it has a welded steeltube fuselage and tail assembly. Its wings use spruce spars and ribs built from 1/4-inch square spruce, ply gusseted. Steel tubing also forms the flying struts for the wing, but a little balsa wood is used for fairing. Power is supplied by either the Heath B4 or a converted VW engine.
