The Avion was supplied as a kit for [[Homebuilt aircraft|amateur construction]].<ref name="Cliche">Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page E-3. Cybair Limited Publishing, 2001. {{ISBN|0-9680628-1-4}}</ref>

==Design and development== 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 Avion has a standard empty weight of {{convert|240|lb|kg|0|abbr=on}}. The Avion features a [[strut-braced]] [[high-wing]], single-seat, open cockpit, single [[pusher configuration|pusher]] engine configuration, and is equipped with [[tricycle landing gear]].<ref name="Cliche" /><ref>Berger, Alain-Yves and Norman Burr: ''Berger-Burr's Ultralight and Microlight Aircraft of the World'', Volume 16, page 173. Haynes Publishing Group, 1983. {{ISBN|0-85429-390-6}}</ref>

The aircraft is made from bolted together [[aluminum]] tubing, with the [[wing rib]]s constructed from stamped aluminum. The wing and tail covering is [[Dacron]] sailcloth. Its {{convert|34|ft|m|1|abbr=on}} span wing is supported by "V" [[lift strut]]s. The tail is mounted to a straight aluminum tube that passes above the pusher propeller. Both the [[Elevator (aircraft)|elevator]] and [[rudder]] are [[Stabilator|all-flying]] surfaces; the [[aileron]]s are full-span. The standard engine fitted was the [[Rotax 277]] of {{convert|28|hp|kW|0|abbr=on}}. The fuel tank was integral with the pilot's seat and common with Brock's gyroplane designs. The pilot sits on the seat in the open air, with no windshield. The [[landing gear]] is of tricycle configuration and features a steerable nosewheel and hydraulic brakes. The Avion can be assembled for flight in 30 minutes.<ref name="Cliche" />

The Avion underwent a complete engineering [[stress analysis]] by [[Bob Hovey]], the designer of the [[Hovey Delta Bird]] and [[Hovey Whing Ding II]]. The Avion was designed to +6/-4[[g-force|g]].<ref name="Cliche" />
