This 15-hp, 300-pound gross-weight biplane is the ultimate in lightness and simplicity. The tail surfaces are constructed from 1/2-inch-thick Styrofoam art board faced with high-strength craft paper on both sides; the critical areas are reinforced with 1/8-inch plywood gussets. The tail boom is a 3-inch aluminum pipe filled with foam to resist buckling. The fuselage is basically a 6-inch wide box of plywood filled with foam that serves as an engine mount and a mast support for the wings. The prop is chain driven from a 15-hp McCulloch, twocycle, go-kart engine. The wings have two spars and are fabric covered.
