The '''Reid and Sigrist R.S. 1''' was a [[United Kingdom|British]] twin-engined, three-seat advanced trainer developed in the [[World War II|Second World War]].

==Design and development==
Reid and Sigrist in [[Desford]], [[Leicester]], United Kingdom, were an important [[Flight instruments|instrument]] manufacturer in the interwar era, specialising in aircraft applications leading to the forming of an aviation division in 1937 at [[New Malden]], Surrey factory site. The first product was a unique twin-engined advanced trainer powered by a pair of [[de Havilland Gipsy Six]] II (205&nbsp;hp, 152&nbsp;kW) engines.<ref>Gunston 1996, p. 136.</ref> Although basically a conventional mid-wing "taildragger" design with mainly wooden construction (the tail surfaces were fabric covered), the fuselage/wing surfaces had plywood covering, and the cockpit featured a sliding canopy for the three-seat configuration, that was in vogue at the time for training.<ref name=Swanborough/> An alternate light bomber configuration was also proposed with a pilot and radio operator/navigator in the front compartment and a rear-facing gunner position behind equipped with a single machine gun.<ref>Gunston 1996, p. 137.</ref>

==Operational history==
The prototype, registered as ''G-AEOD'' on 9 October 1936, had its first flight early in 1939 with Reid and Sigrist test pilot George E. Lowdell at the controls.<ref name=Swanborough>Swanborough 1997, p. 80.</ref> The R.S.1 named whimsically  "Snargasher" by the factory workers during its construction (the name which was eventually formally adapted had no meaning other than as a "family joke") made its first public appearance at the Heathrow Garden Party of the [[Royal Aeronautical Society]] on 15 May 1939 with its [[Certificate of Airworthiness]] issued on 3 June 1939.<ref>Gunston 1996, pp. 136–137.</ref>

Further development of the type was suspended as the company became a wartime engineering and production concern with [[Bolton-Paul Defiant]] and [[Hawker Hurricane]] assembly and repair contracts. The R.S.1 was used as a communications aircraft by Reid and Sigrist, retaining its civil registration but flying in green/brown camouflage until the sole prototype was broken up in 1944. By that point, a more definitive development had been started, the [[Reid and Sigrist R.S.3/4|R.S.3 "Desford"]] which was intended for postwar use.<ref name=Swanborough/>
