The aircraft is supplied as a kit for [[Homebuilt aircraft|amateur construction]].<ref name="KitplanesDec2011">Vandermeullen, Richard: ''2011 Kit Aircraft Buyer's Guide'', Kitplanes, Volume 28, Number 12, December 2011, page 46. Belvoir Publications. ISSN 0891-1851</ref>

==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 {{convert|254|lb|kg|0|abbr=on}}. The aircraft has a standard empty weight of {{convert|251|lb|kg|0|abbr=on}}. 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.<ref name="KitplanesDec2011" />

The aircraft structure is made from [[aluminum]] tubing, with foam [[wing rib]]s. Its {{convert|34|ft|m|1|abbr=on}} 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 {{convert|14|hp|kW|0|abbr=on}} each, which give a cruise speed of {{convert|50|mph|km/h|0|abbr=on}} and a rate of climb of 400 ft/min (2.0 m/s).<ref name="KitplanesDec2011" /><ref name="Radne">{{Cite web|url = http://www.waspsystems.co.uk/spec.html|title = Radne Racket|accessdate = 19 November 2011|last = Wasp Systems|date = n.d.|url-status = dead|archiveurl = https://web.archive.org/web/20120425232617/http://www.waspsystems.co.uk/spec.html|archivedate = 25 April 2012}}</ref>

The construction time from the supplied kit is estimated by the designer at 160 hours.<ref name="KitplanesDec2011" />
