From Wikipedia, the free encyclopedia
The Sonex is a lightweight, metal, low-wing homebuilt aircraft that seats two. Kits are produced and marketed by Sonex Aircraft, a small manufacturer based in Oshkosh, Wisconsin.
[edit] Development
Designed to meet the needs of European and American sport aircraft markets, the Sonex can accept various lightweight –less than 200 lb ( kg) – engines of between 80 and 120 hp. Due to the aircraft's light weight, it fits the requirements for the new light-sport aircraft regulations. The Sonex plans contain several construction options, including conventional or tricycle landing gear, as well as a center or dual stick. Motor mount drawings are supplied for all three recommended powerplants: the 2180cc Volkswagen, 2200 Jabiru, and 3300 Jabiru. High performance is achieved through a clean aerodynamic shape and simple, light weight construction. The Sonex can be built from scratch using factory supplied drawings or may be assembled in approximately 800 to 1,000 hours using the precut complete airframe kit. A complete kit based Sonex can be constructed for as little as $25,000. The aviation website Aero-News.Net named the Sonex the kit plane of the year for 2006.
