variants with their own articles=The Bensen B-7 was a small rotor kite developed by Igor Bensen in the United States in the 1950s and marketed for home building. It was a refined to be a slightly larger version of the B-6, replacing the skids with a tricycle undercarriage, and adding a single large fin to the rear of the aircraft.

The B-7 was first towed aloft on 17 June 1955, and on 6 December that year, Bensen flew a motorized version designated the B-7M, a fully autonomous autogyro. The prototype B-7M crashed three days later with Bensen at the controls. Although the machine was soon repaired and in the air again, the incident set Bensen to work on further refinements to the design that would eventually lead to the B-8.
