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 . Little Nellie and another sixteen of his autogyros are currently on static display with his second cousin at Wallis & Son Land Rover showrooms in Barton, Cambs.
Design and development
[ edit ]
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
[ edit ]
In 1962, five WA-116s were built by Beagle Aircraft at Shoreham , three of which were for evaluation by the British Army Air Corps . Wallis flew one of these aircraft, XR942 , at that year's Farnborough Air Show .[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 legendary music hall performer 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] Wallis withdrew all his autogyros from use by anyone other than himself, after the crash of WA-117 G-AXAR at the 1970 Farnborough Air Show .[5]
