Back American Sportscopter Ultrasport 331
1993

Ultrasport 331

American Sportscopter (ASI) was formed in 1990 to produce an ultralight helicopter to FAR Part 103, which was designated Ultrasport 254. This kit-built machine first flew in July 1993. It is a single-seater with a semi-enclosed composite fuselage structure, skid undercarriage and a tubular tailboom with tailplane and twin fins and a tail rotor enclosed in a large circular shroud. It is powered by a 55hp Hirth 2703 engine mounted behind the cockpit rear bulk-head. The Ultrasport 331 is a larger version of the 254 falling within the American "Experimental" category (FAR Part 21.191g), with increased range and higher gross weight. This first flew in December 1993. It was followed by the Ultrasport 496 two-seater which commenced flight testing in July 1995. It has a wider cabin than the 331 and uses a 95hp Hirth F.30 engine. The Ultrasport helicopter kits are manufactured in Taiwan.

R.Simpson "Airlife's Helicopter and Rotorcraft", 1998 American Sportscopter International Inc. was founded in 1990. North and South American markets are covered by US office; rest of world by Taiwanese office. An unmanned surveillance prototype named Vigilante 496 (first flight February 1998) was developed by SAIC. In late 2001, ASH was looking at providing armament, including 70mm rockets and Hellfire missiles.
