X-Plane 11 Kitfox 3 1.0. The Denney Kitfox is a series of small side-by-side two-seat high-wing kit aircraft, designed and originally manufactured by Dan Denney and his company Denney Aerocraft of Boise, Idaho. The Kitfox Model 3 features structural changes that were designed to improve flight characteristics and provide a better platform for more powerful engines. This has been my real life aircraft since 2002. The engine is a 85 HP Jabiru 2200. My first attempt to bring it to X-Plane 11. Any comments would be more than welcomed! By Michel Verheughe.
