The 340 was introduced in 1991. Sabre Aircraft ceased operations in 2008.[3]
The aircraft was designed with a focus on low cost, to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 2540NaN0. The aircraft has a standard empty weight of 2150NaN0 with the Sabre 14 wing. It features a cable-braced hang glider-style high wing, weight-shift controls, a single-seat open cockpit, tricycle landing gear and a single engine in pusher configuration.
The aircraft is made from tubing, with its single-surface Sabre 14 wing covered in Dacron sailcloth. Its 341NaN1 span wing is supported by a single tube-type kingpost and uses an "A" frame control bar. As a budget design the basic aircraft has no cockpit fairing or windshield, but does feature nosewheel suspension and heavy-duty main landing gear struts as standard equipment. The standard engine supplied was the twin cylinder, two-stroke, air-cooled Kawasaki 340 snowmobile engine, which produces 300NaN0. Available factory options included a fiberglass cockpit fairing, nosewheel brakes, wheel pants, ballistic parachute and an aero-tow kit. Optional engines included the 400NaN0 Rotax 447 and the 500NaN0 Rotax 503. The standard wing supplied was Sabre Aircraft's own Sabre 14 single-surface wing, with the double-surface Ukrainian-built Aeros Stranger 15 wing optional.
The design achieved a very low price point and in its basic configuration sold for US$6,000, complete and ready to fly, in the late 1990s. It was the least expensive complete aircraft available at that time.
