The SportStar was the first approved special light-sport aircraft (S-LSA) and was named "S-LSA Aircraft of the Year" by AeroNews Network.[1]

Design and development

The SportStar is an all-metal design made from anodized, corrosion-proofed aluminum. The airframe uses a pop-riveted and bonded construction, which the company claims will improve fatigue characteristics and result in a longer service life. The company also claims this construction technique results in better crashworthiness, the elimination of rivet zippering in an accident and quieter in-flight noise levels due to the elimination of oil-canning and flexing.[3]

The SportStar was designed for towing sailplanes up to 1544 lbs (700 kg) gross weight and for towing banners up to 1479 sq ft (140 m2).[4]

Variants
EuroStar SL
Model for the European ultralight category, with a gross weight of 1,041 lb (472 kg)[2][5]
