• Design and development
    In 1928 Blackburn designed and built a private venture lightweight biplane fighter powered by an Armstrong Siddeley Lynx IVC engine. The Blackburn F.2 Lincock was of wooden construction and first appeared in May 1928. It performed well in demonstrations but failed to gain any orders. The Canadian government showed an interest in the design, and a metal construction variant (the Lincock II) was built. It was tested in Canada at Camp Borden in 1930 where there was interest in using the Lincock as an advanced trainer, but the type was not ordered. It was later used to perform public aerobatic displays in 1933 and 1934.

    The final version was the Lincock III of which five were produced, two were delivered to China, two to Japan and one retained as a demonstrator. Interest from Italy resulted in Piaggio acquiring a licence to produce a two-seat version as an aerobatic trainer, though only one Piaggio P.11 was built.
