The Scheutzow Model B or Scheutzow Bee was a two-seat utility helicopter developed in the United States in the late 1960s and early 1970s.^[1][2]

The aircraft was designed by Webb Scheutzow around a new type of rotorhead that he had developed, the FLEXIHUB.^[1] In this system, the two main rotor blades were mounted in rubber bushes, reducing vibration and requiring no lubrication.^[1][3] The design was otherwise entirely conventional, consisting of a cabin with two seats arranged side-by-side, a centrally-mounted engine and rotor mast, and an open-truss tail boom of triangular section that carried a two-blade tail rotor.^[1][4] The undercarriage consisted of skids.^[4] The frame was constructed of welded steel tube^[4] and the cabin was constructed of sheet metal.^[4][5] Power was transmitted from the engine to the rotor by a series of belts, eliminating the need for a gearbox^[6] and minimizing cabin noise.^[4]

The prototype (registration N564A) first flew on 26 January 1967^[1] and Scheutzow initially planned to have flight testing for type certification completed by the end of the year.^[5] At the time, Scheutzow hoped to sell the helicopter for somewhere in the region of $10,000–$12,000,^[5] although the following year, the estimated price rose to $16,700.^[6] Scheutzow still hoped that the helicopter would be in production the following year and planned to build 191 examples in 1969.^[6] However, the flight test program to obtain type certification did not commence until 1971.^[4] Certification tests were almost complete by the end of 1973, at which point funding ran out.^[4] Testing resumed again in February 1975^[4] and the Bee was certified in May 1976.^[7] Development was abandoned during the 1970s after only four examples were built.^[1]
