|Number built||75 (1998)|
The aircraft was introduced in 1988 and production ended when the company went out of business in circa 2008.
Design and development
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 247 lb (112 kg). The aircraft was designed to be a single-place or optionally two-seater. The base model High Flyer features an MK Superfit rip-stop nylon parachute-style high-wing, tricycle landing gear and a single 45 hp (34 kW) 2si 460-F engine in pusher configuration. Variants use other engines.
The aircraft is built from a combination of bolted 6061-T6 aluminium, welded 4130 steel tubing and mild steel. 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 suspension. The aircraft was factory supplied in the form of an assembly kit that requires 30–40 hours to complete.
Reviewer Andre Cliche described the aircraft as "a proven design".
By 1998 the company reported that 75 kits had been sold and 75 aircraft were completed and flying.
