The Wallis WA-116 Agile is a British autogyro developed in the early 1960s by former Royal Air Force Wing Commander Ken Wallis. The aircraft was produced in a number of variants, one of which, nicknamed Little Nellie, was flown in the 1967 James Bond film You Only Live Twice.

Design and development

Wing Commander Ken Wallis, a former RAF pilot, developed a number of improvements to the autogyro design, including the offset gimbal rotor head which gives the autogyro hands-off stability.[1] Wallis' first prototype autogyro, registered G-ARRT, was first flown on 2 August 1961.[2]

Operational history

In 1962, five WA-116s were built by Beagle Aircraft at Shoreham, three of which were for evaluation by the British Army Air Corps.[2] In 1966, one of the Beagle-built WA-116s, registered G-ARZB, was modified for use in the James Bond film You Only Live Twice.[3] Little Nellie was named after Nellie Wallace.[4] Few Wallis autogyros have been operated privately, with nearly all of them being used for research and demonstration flying by Wallis himself.[3]
