Bristol Scout

"Vickers Challenger synchroniser (Bristol Scout)" by An unknown member of the Australian Flying Corps, 1916 - Roberts, e.g. Boxkites and beyond, Melbourne, Hawthorn Press, 1976. Licensed under Public domain via Wikimedia Commons.

After its first public appearance, by May 1914 what would later become known as the "Bristol Scout A" had been refitted with a longer span - at 24 ft 7 in (7.49 m) set of wing panels that were rigged with 1 3⁄4° of dihedral, replacing the initial 22 ft (6.71 m) span panels, a larger surface area rudder, and a much more conventional open-front, ring-style, "six segment" cowl to house the 80 hp Gnôme Lambda rotary engine. The British military first evaluated the Scout A aircraft on 14 May 1914, at Farnborough, when the aircraft achieved a top airspeed of 97.5 mph (157 km/h).[1] The Scout A also entered two air races in the summer of 1914 after being purchased by British Lord Carbery for £400 without its engine. Flying with an 80  Brianhp Le Rhône 9C nine-cylinder rotary installed by its purchaser, it was ditched in the English Channel during the second air race it participated in; a round trip from Hendon in the UK to the French Buc aerodrome (near Versailles) and back, due to its running out of fuel. While in France, the tanks had been only half-filled by mistake.
