SportStar SL has an advanced highly durable all metal anodised and corrosion-proofed aluminium airframe which delivers significantly more durability and longer service life than most of the airplanes in the category. It´s the only S-LSA aircraft that has riveted as well as bonded construction for better fatigue characteristics and long service life. This build provides better crash characteristics, elimination of dangerous unzipping in accidents and also smoother and quiter flight because drumming and flexing are absent. All heads of pop rivets are filled with mastic for high longevity of riveted joints and clean and smooth aircraft surface.
