The R6 helicopter (also known as the HoverflyII) was designed based on the successful Sikorsky R4 model. He has a more advanced aerodynamic shape of the fuselage. The rotor and transmission are borrowed from the R4 model, and the engine is vertically mounted. Unlike the R4, the hull shell is made of fiberglass, aluminum tail boom. Improvements made it possible to achieve greater speed: 100 miles per hour compared to 82 miles from R4.
