 Carbon fiber rovings were used to build the wing spars, while the skin was made of carbon fiber scrims () as a weight saving measure.Both pilots sit in tandem in a cockpit placed forward of the wing, fitted with dual controls, under a long, single-piece canopy.The fuselage is split horizontally, as with the fs31, instead of vertically to improve pilot safety during a crash landing by eliminating a seam on the underside of the cockpit.
