The Pobjoy Niagara is a British seven-cylinder, air-cooled, radial, aero-engine first produced in 1934, with an unusual offset-from-centre propshaft due to its engine reduction gearing. The Niagara was a popular engine for light and experimental aircraft. The entire series of Pobjoy motors were seven-cylinder radials with compact dimensions and very high rpm. The entire Pobjoy range was well regarded due to its small diameter, smooth operation, low noise and innovative engineering.

The Bristol Mercury is a nine-cylinder, air-cooled, single-row, piston radial engine. Designed by Roy Fedden of the Bristol Aeroplane Company it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Jupiter engine, later variants could produce 800 horsepower (600 kW) from its capacity of 1,500 cubic inches (25 L) by use of a geared supercharger.

Almost 21,000 engines were produced with a number also being built in Europe under licence. At least three Bristol Mercuries remain airworthy in 2010 with other preserved examples on public display in aviation museums.
