About the Rans S-7 Courier

The RANS S-7 Courier is an American light sport and ultralight kit aircraft designed for backcountry flying and short-field operations. Built by RANS Designs of Kansas since the late 1980s, the S-7 is a high-wing, tube-and-fabric taildragger that can be assembled by amateur builders in a few hundred hours. Its defining characteristic is exceptional slow-flight capability: stall speed with full flaps is around 28 knots, making it one of the slowest-flying fixed-wing aircraft in production.

The Courier is typically powered by Rotax two-stroke or four-stroke engines in the 50-80 horsepower range, giving it a cruise speed around 80-90 knots and a range of roughly 300 nautical miles. With a maximum takeoff weight just over 1,000 pounds, it qualifies as an ultralight or light sport aircraft in many jurisdictions, and its folding wings allow for trailer storage. The S-7 has found a loyal following among bush pilots and recreational flyers who value its rugged simplicity, low operating costs, and ability to operate from grass strips, sandbars, and other improvised surfaces.
