The Kraft K-1 Super Fli is a single-seat sport aircraft that was designed in the United States in the early 1970s and marketed for homebuilding. It is a low-wing cantilever monoplane of conventional design with fixed, tailwheel undercarriage. The wings have a wooden structure, skinned in plywood, while the fuselage and empennage are built from steel tube, the fuselage skinned in aluminium and the tail in fabric. It has a very similar design to radio controlled craft.

The Super Fli's designer, Phil Kraft, was a champion builder and flier of radio-controlled model aircraft who in 1972 decided to apply this expertise to the design of a full-size aircraft. The design therefore reflected guidelines normally applied to model aircraft, particularly in its wing design, areas, and moments. Kraft also designed a scale model of course, which was published in Model Airplane News and was later kitted by Bridi and Great Planes. Plans for the model remain available from MAN.
