Sonex Aircraft is an American aircraft kit manufacturer located in Oshkosh, Wisconsin, producing kits for four all-metal homebuilt monoplanes. The company is led by John Monnett who has designed the Monnett Sonerai sport aircraft series, Monnett Monerai sailplane, Monnett Moni motorglider, and Monnett Monex racer. Monnett designs are displayed in the Steven F. Udvar-Hazy Center of the National Air and Space Museum near Washington D.C. 

The Onex (pronounced ?One-X?) is a single-seat aircraft designed to offer an even-more economical way to build and fly a sport pilot aircraft. The folding-wing design can fit into a garage, or share a T hangar with other aircraft, be trailered on local roads, and the wing panels are easily removed for trailering at highway speeds.  

The Onex follows the Sonex Aircraft design and engineering tradition in offering a simple, robust, aerobatic aircraft capable of squeezing incredible performance out of lower powered engines. Like all other Sonex Aircraft, the Onex is designed for use with the AeroConversions AeroVee Engine. The simple, low cost, and technically advanced AeroVee Engine Kit is a perfect fit for the Onex, offering outstanding performance and economy.  

Sonex Aircraft is a leader in the experimental kit aircraft industry, providing a series of Sport Pilot eligible kit aircraft and producing the AeroConversions line of products which include the AeroVee engine, AeroInjector and ancillary aviation products.  

The Onex Complete Airframe Kit and Sub-Kits are the most advanced kits ever produced by Sonex Aircraft, offering more than ever before in pre-fabricated parts and matched-hole tooling. Staying true to the Sonex Aircraft mission of offering The Best Performance Per Dollar, Onex kit builders can get their aircraft flying for as little as $25,299. 

Sonex Aircraft?s Sonex, Waiex, and Onex sport planes, and the Xenos sport motorglider offer outstanding performance in an easy to build, easy to fly kit package that can be purchased and completed with full technical support at an unrivaled price.
