Its wings are built around twin spruce spars and, like the rest of the aircraft, fabric covered.

The fuselage has a flat-sided steel tube Warren girder structure with two open cockpits, one between the wings and the other just aft of the upper trailing edge with an extended, faired headrest.

The tailplane and elevators are mounted on top of the fuselage and the fin and unbalanced rudder have a rounded profile.

[1] The landing gear is fixed and of the split axle type, with mainwheels on V-struts from the central fuselage underside and with vertical oleo struts from the outer axle to the wing leading edges, where single bracing struts connect to the upper fuselage longerons.

[1] The Sport prototype, powered by a 55 hp (41 kW) Velie M-5 engine, first flew on 27 January 1930.
