Design and development
The single seat Eco 6 was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). 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.[1]
The aircraft is made from bolted-together aluminum tubing with steel brackets, with its single surface wing covered in Dacron sailcloth. Its 9.60 m (31.5 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame control bar. A variety of single-surfaced wings can be used on the Eco 6, with wing areas ranging from 14.0 to 16.1 m2 (151 to 173 sq ft). The Eco 6 had a factory option of a Galaxy ballistic parachute. The standard engine supplied was the 30 kW (40 hp) Rotax 447.[1]
Developed from the Eco 6 were two two-seat models, the Dolphin 3 and the Cross 5. The three aircraft line commenced production in the mid-1980s and was introduced into the United States in 1997, represented in the US by AKS of Portland, Oregon.[1]
