What is the Onex?
Onex (pronounced “One-X”) is a single-seat aircraft designed to offer an even-more economical way to build and fly your sport pilot aircraft! The folding-wing design can fit into a standard 7’ garage door, and the wing panels can easily be 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.
