Rotorcraft Ltd was established with backing from Mitchell Engineering in the early 1960s to produce a new two-seat design by J.S.Shapiro. The "Grasshopper" in its definitive form had a fuselage somewhat similar to an enclosed sports car with a small v-tail and a skid undercarriage. It was powered by a pair of 65hp Walter Mikron piston engines mounted in the nose. These drove a pair of two-blade coaxial rotors mounted on a pylon which emerged just ahead of the cockpit windshield. G-ARVN, the prototype, flew in March 1962, but was withdrawn from use the following spring when funding was withdrawn following the death of the owner of Mitchell Engineering, and the project was abandoned.
