History
Alliott Verdon Roe's company was already established as a serious aircraft manufacturer by 1913 when the Type 511 appeared as a light racing biplane. It participated in the 1913 Aerial Derby at Hendon, representing Avro's foray into the competitive air racing scene of the pre-war era. Only a small number were built, and the type's development was overtaken by the outbreak of World War I in 1914.
Variants
The Avro 511 was a one-off or very small series; it did not develop into a production family.
