The Cleanex was designed and built by Dan Weseman. The Cleanex is comprised of a Sonex airframe from the firewall back and the powerplant is a William Wynne style 3100cc Big Boy Corvair engine encased in a custom cowling. The Cleanex's first flight took place on September 11th, 2005. Through building and flying the Cleanex we found the need to improve the service life and strength of the Corvair crank shaft by adding an additional bearing on the front of the engine.
