Rolls-Royce Buzzard

The Rolls-Royce Buzzard was a British piston aero-engine of 36.7 litres capacity generating about 800 hp (600 kW). It had 12 cylinders in a 'V' configuration of 6 inch bore and 6.6 inch stroke. It was manufactured in the late 1920s, but only 100 were sold, mostly for racing. It was also referred to as the H engine, which was developed into the Schneider Trophy engine, the R. It was developed by scaling-up the Kestrel in the ratio of 5:6.
