Sauper J300 Joker

Regularly updated, Sauper engineers have lately developed the 4th series with better manoeuvrability and responsiveness thanks to its shortened wings.

As a simple UL aircraft, it was sold only in a ready-to-fly version.

A classic design microlight single-engined aircraft with a high wing, two side-by-side seats, the structure is made of 25CD4S tubes of aeronautics steel. TIG weldings and tubes are protected from corrosion. The fuselage is covered with aeronautics Diatex 100 and 1500 fabric.

Fitted with complete double controls, 2 points security seatbelts, and Lexan F 5006 windscreen and windows, there is a large luggage area behind the seats. The mains have 600×6 tires with disc brakes. Two aluminium seat-tanks of47 litres are fitted.

Saunders-Roe A.37 Shrimp

After designing the S.38 four-engined patrol flying-boat to Specification R.5/39, Saro built, as a private venture, a two-seat half-scale model as the Saro A.37, often called the Shrimp. The R.5/39 programme did not go ahead, but the Saro A.37 was completed in time to make its first flight in October 1939. Powered by four 63kW Pobjoy Niagara III engines, it was later modified to have a single fin and rudder, and other features representative of the Shetland flying-boat jointly developed by Shorts and Saro. In this guise, it acquired the serial TK580, and was tested from early 1944 until after the war had ended. The Shrimp was dismantled in Felixstowe in 1949.

Saunders-Roe S.36 Lerwick

The twin-engine Sarò Lerwick was intended to meet a medium-range maritime reconnaissance requirement, Specification R. 1/36. First flown before the end of Ì938, the prototype featured twin fins and. rudders but from the outset was found to be lacking m lateral stability, and displayed a determination to roll and yaw in cruising flight, making the aircraft impossible to fly ‘hands off”. In due course a single fin and rudder was fitted, but not until this was considerably enlarged was there any improvement in the handling.

Starting with the seventh production example, wing incidence was increased and enlarged propellers fitted to the Hercules II radials, but the propellers were found unsuitable for operating on rough water. Stalling tests showed the Lerwick to have vicious traits, the stall under alighting conditions being accompanied by sharp wing-drop.

Twenty one examples were produced and the Lerwick was first delivered for service with No, 209 Squadron in December 1939 at Oban, but after the type had flown a small number of semi-operational patrols it was decided to abandon further efforts to rectify its problems. The last eight aircraft were powered by Hercules IVs and the final example was completed in November 1940. One aircraft was flown by No, 240 Squadron but was lost on 20 February of that year, and some flew with No. 4 Operational Training Unit at Invergordon.

Saunders-Roe S.27 London

Reflecting the design concept of British flying-boats that had originated in the 1920s, the Sarò London twinengine biplane was an all-metal aircraft with fabric-covered wings and tail, and a metal-skinned hull. The type served with RAF Coastal Command during the first two years of World War II. Designed to Air Ministry Specification R. 24/31, the prototype first flew in 1934 with two 559kW Bristol Pegasus III radiais, the engines being mounted on the top wing to be well clear of spray while taking off and landing; the prototype went on to serve for periods between 1934 and 1936 with Nos 209 and 210 Squadrons at Felixstowe and Gibraltar.

Production deliveries started in March 1936 with Pegasus III engines, but from the eleventh aircraft the Pegasus X was fitted and the aircraft’s designation changed to London Mk II, this variant equipping Nos 201 and 204 Squadrons in 1936 at Calshot and Mount Batten repectively. In 1937 they joined No. 202 Squadron at Kalafrana (Malta) and No. 228 Squadron at Pembroke Dock respectively. By the outbreak of war in September 1939 Londons still equipped No. 201 Squadron, then at Sullom Voe in the Shetland Islands, and No. 202 Squadron still at Gibraltar, while No. 240 Squadron had re-equipped with Londons in July 1939 and was stationed at Invergordon, These flyingboats carried out sea patrols over the North Sea and the Mediterranean, some aircraft being fitted with a large dorsal fuel tank to increase their range. Bombs, depth charges and (occasionally) mines up to a total weight of 907kg could be carried under the lower wing roots. Indeed, the old biplanes undertook a considerable share of the patrol work over the North Sea, keeping watch for the likely breakout into the Atlantic by German surface and submarine raiders as well as the return to German port by blockade runners. Gradually maritime reconnaissance aircraft such as the Lockheed Hudson came to assume these responsibilities while Short Sunderland flying-boats equipped the squadrons flying over the Atlantic and Mediterranean. The Londons were replaced on No. 201 Squadron in April 1940, followed two months later by those on No. 240 Squadron. Only No. 202 Squadron continued to fly Londons at Gibraltar until June 1941.

Saunders-Roe A-19 Cloud

The 1931 Cloud amphibious flying-boat was produced in two forms: as a civil eight-seater and as a military trainer. In the latter role the RAF received 16 from 1933. The large cabin provided accommodation for eight pupils; six pupils and wireless and electrical equipment, navigation instruments and signalling apparatus; or four pupils and the above equipment for navigational training. Alternatively, the Cloud could be used for flying training, to simulate the conditions to be met with a larger service type of flying-boat. Power was provided by two 253kW Armstrong Siddeley Double Mongoose engines.

The Monospar S.T.7 designation covered the wing structure of the Saro Cloud.

Saunders-Roe A-17 Cutty Sark

A-17C

Saro or Saunders-Roe produced the Cutty Sark four-seat cabin flying-boat (or amphibian) as its first new design after formation in 1928. It was adopted for flying-boat and navigational training by Air Service Training Ltd (two 112kW Armstrong Siddeley Genet Major engines) and was exported as a coastal-reconnaissance aircraft (de Havilland Gipsy Major engines).
