de Havilland DH51 Full Engine Run

The DH51 was first flown in 1924 by Geoffrey de Havilland, and was initially designed as a three-seat biplane. Later, provision was made for a fuselage fairing to permit luggage being stowed in lieu of a third passenger.
The DH51 was initially powered by a 90hp Royal Aircraft Factory 1a engine, however because of its lack of dual ignition required for civil use, its Certificate of Airworthiness (CoA) was refused. The engine was then changed to a 120hp Airdisco which, despite taking the aircraft out of intended economic operating limits, provided improved overall performance.
Shuttleworth's DH51 was the first aeroplane to be registered in Kenya, where it remained in service for nearly 40 years. In 1965, it was air freighted back to the UK. In 1972, it was flown to Old Warden and placed in the permanent care of The Shuttleworth Collection.
The aircraft was repainted in 2011 for a British Airways advert, mimicking a DH9 operated by Aircraft Transport and Travel, and has subsequently appeared in other television productions including Mr Selfridge.
The Shuttleworth Collection in Bedfordshire, England is home to a vast array of vintage aircraft, vehicles, as well as agricultural machinery. The Collection hosts a series of flying days from May to October each year, and is open to the public on non-flying days as well.
