Design and development

Even though it is a Canadian design, 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 251 lb (114 kg). It features a strut-braced high-wing, inverted V-tail, a single-seat, open cockpit, conventional landing gear and twin engines in tractor configuration. The EZ Fun Flyer closely resembles the Ultraflight Lazair in configuration and dimensions.[1]

The aircraft structure is made from aluminum tubing, with foam wing ribs. Its 34 ft (10.4 m) span wing is supported by a single lift strut per side. The engines are Radne Raket 120 single cylinder, 120cc, air-cooled, two stroke powered hang glider powerplants of 14 hp (10 kW) each, which give a cruise speed of 50 mph (80 km/h) and a rate of climb of 400 ft/min (2.0 m/s).[1][2]

The construction time from the supplied kit is estimated by the designer at 160 hours.[1]

Operational history

Only one example has been registered in Canada.[3][4]
