The S-18’s legacy is not in its sales figures but in its design ideas. Thorp’s mechanical landing gear retraction system was later adapted by other homebuilders. The mid-wing concept, though rare in production aircraft, influenced experimental designs for decades. And the S-18 remains a powerful lesson: in aviation, engineering excellence is necessary but not sufficient. Without timing, capital, and marketing, a better mousetrap may still go unbuilt.

The S-18’s fuselage was a with exceptionally clean rivet work and a distinctive, rakish nose. It seated four in "club seating" (two front, two rear facing forward), and featured a wide, comfortable cabin. Power came from a 180 hp Lycoming O-360-A1A —the same engine used in many Pipers and Cessnas.
