Troyer Sportplane VX

There are few homebuilts that weigh less than this VW-powered mid-wing model. The Troyer Sportplane weighs only 306 pounds empty. Oddly enough, it has a welded steel tube fuselage and tail assembly. Its wings use spruce spars and ribs built from ¼-inch square spruce, ply gusseted. Steel tubing also forms the flying struts for the wing, but here a little balsa wood does creep in. It is used for fairing. Power is supplied by either the Heath B-4 or a converted VW engine.
