Design and development

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles trainer exemption as well as the US Experimental - Amateur-built aircraft rules. It features a 525 sq ft (48.8 m2) parachute-style wing, two-seats-in-tandem or side-by-side configuration, tricycle landing gear and a single 50 hp (37 kW) Rotax 503 engine in pusher configuration. The 65 hp (48 kW) Hirth 2706 engine was a factory option.[1]

The aircraft carriage is built from a combination of bolted aluminium and 4130 steel tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates sprung steel rod suspension. The aircraft has a typical empty weight of 254 lb (115 kg) and a gross weight of 754 lb (342 kg), giving a useful load of 500 lb (230 kg). With full fuel of 10 U.S. gallons (38 L; 8.3 imp gal) the payload for the pilot, passenger and baggage is 440 lb (200 kg).[1]

The standard day, sea level, no wind, take off with a 50 hp (37 kW) engine is 100 ft (30 m) and the landing roll is 50 ft (15 m).[1]

The manufacturer estimated the construction time from the supplied assembly kit as 20 hours.[1]

Operational history

By 1998 the company reported that six kits had been sold and two aircraft were completed and flying.[1]

In April 2015 one example was registered in the United States with the Federal Aviation Administration.[2]
