The Monnett Moni is a sport aircraft developed in the United States in the early 1980s and marketed for homebuilding.
Designed by John Monnett, who coined the term "air recreation vehicle" to describe it,[1] it is a single-seat motorglider with a low, cantilever wing and a V-tail. Construction is of metal throughout, and it is intended to be easy and inexpensive to build and fly. Like many sailplanes, the main undercarriage is a single monowheel, which in this case was mounted in a streamlined fairing beneath the fuselage and is not retractable, with a steerable tailwheel behind it. Builders are also given the option of constructing their example with fixed tricycle undercarriage.[2] Power is provided by a small two-cylinder, horizontally opposed, air-cooled engine.
