Quoting Smithsonian National Air and Space Museum | Monnett Moni:
Schoolteacher John Monnett created the Moni (mo-nee) throughout the early 1980s, and then coined the term ‘air recreation vehicle’ to describe this airplane. Monnett’s style nearly captured all the merits that so numerous leisure pilots longed to find in 1 aircraft. The Moni looked excellent just sitting on the ramp. It performed properly, and an individual reasonably handy with average shop tools could construct one in their own garage. The style had considerably going for it, but like so several homebuilt aircraft just before and given that, a few essential engineering lapses in the style, plus problems with the engine and propeller, relegated the Moni to the category of homebuilt aircraft that guarantee a lot in design and style but fail to deliver. Harold C. Weston generously donated his Moni to the National Air and Space Museum in April 1992. Weston constructed the airplane himself and flew it much more than 40 hours.
Gift of Harold C. Weston.
