Having its own body shop, Daimler had the woodworking ability to build complete aircraft. By the end of 1914, they had built 100 units of the Royal Aircraft Factory B.E.2c.[77] These were followed by the BE12 and RE8.[78] Daimler purchased an open field beside their Radford factory, cleared the site, and made it available to the Government, who turned it into the main RAF testing ground for aircraft built in the Coventry district.[79] Although Daimler tooled up for production of the Royal Aircraft Factory F.E.4 bomber the aircraft was cancelled due to poor performance.[80] The last wartime aircraft produced was the Airco DH.10 Amiens bomber when they were building 80 aeroplanes a month.[76]
