 The design was redrawn from metric to imperial measurements by Vickers, while the first example was built at the Vickers factory at Erith, Kent (now part of Greater London), using the French-built rear fuselage and a French-built engine, but was otherwise the rest of the components were Vickers-built.It made its maiden flight from Vickers' new airfield at Joyce Green, near Dartford in July 1911, piloted by Captain Herbert F. Wood, the manager of Vickers' aviation department.The aircraft was a shoulder-winged monoplane, with a deep but narrow fuselage of fabric-covered steel-tube construction, accommodating two people in tandem.
