Blue Yonder EZ Fun Flyer

The Blue Yonder EZ Fun Flyer is a Canadian twin-engined ultralight aircraft that was designed by Wayne Winters and is produced by Blue Yonder Aviation of Indus, Alberta. The aircraft is supplied as a kit for amateur construction.

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. The aircraft has a standard empty weight of 251 lb. 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.

The aircraft structure is made from aluminum tubing, with foam wing ribs. Its 34 ft 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 each, which give a cruise speed of 50 mph and a rate of climb of 400 ft/min (2.0 m/s).

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