Schneider S.5

Photo of the Schneider S.5Three S.5 racing float planes (N219, N220 and N221) were designed and built for the 1927 Schneider Trophy and were flown by the newly formed RAF High Speed Flight. Streamlining of the fuselage meant there was insufficient room for the fuel and the starboard float was used. This unconventional fuel tank also lowered the centre of gravity and improved the stability in flight. The wings carried built-in radiators to cool the racing engine. N220 won the race with N219 finishing second.

Type: Single seat racing float plane
Engine: 900hp Napier Lion VIIA
Maximum speed: 319.57mph

Schneider S.6/S.6B

The whole of the wing surface area, less the ailerons, were used for cooling the engine and hot oil was piped down the sides of the fuselage causing Mitchell to nickname the S.6B the "flying radiator". In 1929 the S.6, serial no. N247, won the Trophy and N248 broke the World Speed Record.

For the 1931 contest two new S.6B aircraft were ordered, serials S1595 and S1596, and the two 1929 S.6s were reclassified to S.6A and modified to the same standard. S1595 won the Schneider Trophy outright for Britain, and on the same day S1596 broke the World Speed Record. Later the same year, Flt Lt Stainforth finally pushed the speed record to over four hundred miles per hour.

Type: Single seat racing float plane
Engine: (S.6) 1,900hp Rolls-Royce R; (S.6B) 2,350hp Rolls-Royce R
Maximum speed: (S.6) 357.7mph; (S.6B) 407.5mph
