Big X
When Fairchild did not follow up on production offers, Wittman was contacted by Cessna in Wichita, Kansas, to demonstrate the lightweight and strong spring steel landing gear of the Big X. Cessna bought the plane and its production rights in order to use the gear on its new Cessna 195 taildragger. Wittman later produced an updated version in a two-place configuration called the Wittman Tailwind that became a popular homebuilt aircraft.
