The Abbott-Baynes Scud 1 was a parasol-winged single seat glider intended to introduce pilots to soaring flight. It was built in the United Kingdom and first flew in 1931.
The Scud was the first of a series of gliders designed by Leslie Baynes, all of which used the same name. At the time of its first flight in 1931 it was referred to as the Brant Scud because the first prototype was built by Brant Aircraft Ltd. of Croydon. [1] [2] [3] Later aircraft were produced by Abbott-Baynes Sailplanes, a company founded for this purpose. [4] It was designed to fill a gap in performance between the primary gliders and the true sailplanes of the day. Thus the Abbott-Baynes Scud 1, as it became known as after the appearance of the Scud 2 in 1932, was capable of soaring and was light and cheap, though its minimum sink speed of just under 1 m/s was higher than the 0.8 m/s or better expected of the competition sailplanes. [1] [3] Compared with them, the Scud's light weight and short span, combined with wing-tip and fuselage hand holds, made it easy for four people to carry on the ground. [2] [3]
The Scud's wooden cantilever parasol wing had constant chord over about 60% of its span, with some taper outboard particularly on the trailing edge. It was built around two spars, with stress bearing plywood skin forward of the rear spar forming a box spar. Aft, the wing and full span ailerons were fabric covered. On the prototype, all flying surfaces were edged with cord, resulting in a scalloped finish. [3] All three all-moving, wood-framed and fabric-covered tail surfaces were identical and interchangeable, making the rudder appear unusually tall. Each surface, mounted on a short stub tube, had a straight leading edge and was tapered on the trailing edge, which had a central cut-out. [2]
The fuselage was also a wooden structure, square in section and built around four ash longerons but unusually orientated with one diagonal vertical. It was plywood skinned throughout, apart from an inevitable break in the upper longeron and in the upper surface skin for the under-wing open cockpit. The wing was mounted by two parallel pairs of thin struts from the mid-fuselage longerons to the two wing spars. The upper longeron loads were carried across the break via the wing structure by two pairs of struts, one well forward and one well aft of the cockpit to the mounting points on the wing spars, together with a near vertical pair just behind the cockpit. A landing skid extending from the nose to below the wing trailing edge was retained by leather straps very close to the lower longeron, with landing forces absorbed by rubber blocks. [3]
Contemporary accounts emphasised the ease with which the Scud with its two piece wing and readily removable tail surfaces could be dismantled for transport. [3]
The Scud's first flight was on 11 January 1931 at Totternhoe, piloted by Marcus Manton. [1] By the Summer of 1931 it was in production in the Abbott-Baynes works. [4] [5] Production numbers are uncertain; it is known that a total of 12 Scud 1 and Scud 2 were built here, including Scud 1 BGA 300. Another Scud was built before World War II in the Channel Islands. [4] The Scud 1 in the Brooklands Museum is a replica built by the late Mike Beach. [6]
One Scud crashed early in the aircraft's career. On 8 March 1931 Thomas Lander was killed immediately after a first attempt at a winch launching. [7] A Scud 1 was on display at the Gliding Exhibition held at Islington in May 1931. [8] Over the Summer of 1931 Flight recorded several meetings with Scuds in attendance, such as those at Portsmouth [9] and Balsdean. [10] A Scud continued in service in 1934 with the Guernsey glider club. [11]

General characteristics
Performance
The Slingsby T.1/T.2 Falcon or British Falcon) was a single-seat sport glider produced, in 1931–37, by Fred Slingsby in Scarborough, Yorkshire.
The Airspeed AS.1 Tern was a 1930s British glider aircraft, the first aircraft built by Airspeed Limited at York and one of the earliest British-designed gliders.
The Carden-Baynes Auxiliary was the first motor glider with a retractable engine and propeller; it is known as the Abbott-Baynes Scud 3 when engineless. Both aircraft, built in the mid-1930s, were still flying in 2010 as pure sailplanes.
The Sayers S.C.W. was a single seat monoplane glider, designed specifically for the first British gliding competition held at Itford Hill in 1922, an endurance event. Unresolved control problems stopped it from making any competitive flights, but it flew successfully later in the year. It was destroyed on the ground by a storm in December 1922.
The Peyret Tandem or Peyret Alérion, was a French single seat glider of tandem wing configuration. It won first prize at the first British Glider Competition of 1922.
The Abbott-Baynes Scud 2 was a 1930s high-performance sailplane, built in the UK. It was a development of the intermediate-level Scud 1 with a new, high aspect ratio wing.
The Addyman Zephyr was a one-off, single-seat sailplane designed and built by Erik Addyman in the UK for his own use in the 1930s.
The Manuel Crested and Willow Wrens formed a series of wooden, single-seat gliders designed in the UK by W. L. Manuel in the early 1930s, intended for slope soaring. Some were built by the designer, others from plans he supplied. The Dunstable Kestrel was a further development.
The Nyborg T.G.N.1 was a single-seat experimental sailplane built in the early 1930s, its unusual wing design a scaled-up version of the wings of large birds.
The Penrose Pegasus was a 1930s high-wing, single-seat, wooden glider from the UK. Designed, built and flown by Harald Penrose until the start of World War II, only one was built at the time though a reproduction was constructed in the 1990s.
The Stedman TS-1 City of Leeds was a parasol wing wooden sailplane, seating two in tandem open cockpits. Only one was built, by its designer in 1934; it remained active until the outbreak of World War II.
The Bonomi BS.19 Alca was a single seat, tractor configuration motor glider, designed and built in Italy shortly before World War II. It had an unusual retractable undercarriage used only for take-offs. Only one was built.
The Bonomi BS.24 Biposto Rome was an Italian dual control trainer designed for club use. Six were built in the mid-1930s.
The Romeo Ro.35, a.k.a.IMAM Ro.35 was a single-seat glider built in Italy in 1933.
The 1926 German RRG Prüfling of 1926 was a secondary training glider designed for club use. Plans were sold and it was built in Germany and across the world.
The Schleicher Poppenhausen named after the town of Poppenhausen was a two-seat glider, available as a dual control advanced trainer, produced in Germany from 1928.
The Schneider ESG 31 Schlesierland (Silesia) was a representative of a group of German, 16 m span, one-off gliders, built by Schneider in Grunau from 1929 to at least 1931.
Lore and a copy, Musterle, were high performance sailplanes designed at Darmstadt by Paul Laubenthal. Lore was flown successfully by the well known glider pilot Wolf Hirth at the 1929 Rhön (Wasserkuppe) glider competition. Musterle was used by Hirth used to demonstrate the possibilities of "blue sky" thermalling for the first time.
The BSV Luftikus was a German competition glider, designed for economy of construction and first flown in 1929. From 1929 to 1931 it took part in the annual national gliding contests held on the Wasserkuppe, often known as the Rhön contests.
The Vándor (Wanderer) was a 1930s Hungarian single seat glider intended to ready students who had qualified on primary gliders for contemporary soaring and aerobatic aircraft. Only one was built.
