The Vickers Vagabond was Vickers' entrant for the second Lympne light aircraft competition, held in 1924. It was a conventional small biplane, with a very unusual method of trimming. It was eliminated from the trials at an early stage and only one was built.
Following the first Lympne trials held in 1923 for single-seat motor-gliders, the Air Ministry organised a similar event in 1924, this time for low-powered two-seat aircraft. The engine capacity limit was set at 1,100 cc. and, as before, the wings had to fold for easy transport and storage. The trials took place between 29 September and 4 October. Several companies built aircraft for them, including the Blackburn Bluebird, Hawker Cygnet, Supermarine Sparrow and two from Westland, the Woodpigeon and Widgeon.
The Type 98 Vagabond was Vickers' entry. It was a single-bay, wire-braced biplane with wings of constant chord except towards the rounded trailing tips. The wings had equal span and carried marked stagger. There were ailerons on both upper and lower wings, with flaps inboard on the lower wings which could be folded to assist wing-folding. The pilot and passenger sat in open cockpits, the latter under the upper wing. The pilot's upward view was enhanced by a small cutout in the trailing edge of the top wing. The fuselage had a more rounded cross-section than that of the earlier Viget, Vickers' single-seat entry to the 1923 competition, extending a little below the lower wing. The 32 hp (24 kW) Bristol Cherub III flat twin engine was mounted in a smooth nose with the finned cylinders exposed for air cooling. The horizontal tail was similar to that of the Viget, but the fin and rudder were much more rounded. Because of the stagger, the mainwheels were in front of the lower wing, braced to the lower fuselage logeron aft to the front wing spar and forward to a point roughly below the upper wing leading edge.

A most unusual feature of the Vagabond was the method of longitudinal trimming. Rather than changing the angle of the tailplane with respect to the fuselage, the whole rear part of the fuselage was hinged just ahead of the lower wing's trailing edge. This was controlled via a handwheel between the two cockpits; the rear fuselage was raised at the start of a landing descent to increase drag and slow the aircraft. [1]
Early flight trials, with H.J.Pain as pilot revealed a need to stiffen the engine mountings. [1] When this was done, the Vagabond, now fitted with a three-cylinder 1,095 cc Blackburne Thrush radial engine flew well enough at Lympne, but was eliminated in the preliminary rounds. Only one Vagabond, registered as G-EBJF on 1 July 1924 [3] was built. It was deregistered on 24 January 1928.

General characteristics
Performance
The Armstrong Whitworth Awana was a British prototype troop-transport aircraft built to meet a 1920 Air Ministry requirement.
The Bristol Type 91 Brownie was a light sports aircraft produced in the United Kingdom by the Bristol Aeroplane Company in 1924. It was a low-wing cantilever monoplane aircraft of conventional configuration with fixed tailskid undercarriage. The pilot and passenger sat in tandem open cockpits. It won the £1,000 pound prize for second place at the Lympne light aircraft trials in October 1924.
The Blackburn 2F.1 Nautilus was a British single-engine two-seat biplane spotter/fighter built in 1929. Only one was completed.
The Gloster Gannet was a single-seat single-engined light aircraft built by the Gloucestershire Aircraft Company Limited of Cheltenham, United Kingdom, to compete in the 1923 Lympne Trials. Engine development problems prevented it from taking part.
The Bristol M.R.1 was an experimental biplane with an aluminium monocoque fuselage and metal wings, produced by Bristol during the First World War. Two were built to government order.
The Vickers Vellore was a large biplane designed as a freight and mail carrier, in single-engined and twin-engined versions, which saw limited use as freighters and long-range experimental aircraft. A final variant with a broader fuselage, the Vellox, was built as an airliner.
The Vickers Type 207 was a single-engined two-seat biplane designed as a shipborne torpedo bomber to an early 1930s specification. Structurally innovative, only one was built.
The Vickers Type 253 was a single-engined two-seat biplane general-purpose military machine built to a 1930 government specification. It won a production contract, but this was transferred to the same company's monoplane equivalent, the Wellesley. Only one Type 253 was built.
The Vickers Viget was Vickers' entrant for the first Lympne light aircraft competition, held in 1923. It was a single-seat, single-engined biplane with folding wings.
The Vickers E.S.1 was an early British Fighter aircraft of the First World War. A single-seat biplane, only three E.S.1s were built, although at least one was used by a home defence squadron of the Royal Flying Corps.
The Boulton & Paul P.33 Partridge was a single seat single-engined biplane fighter designed to an Air Ministry specification. One prototype was ordered and built for trials in 1928, but it was not put into production.
The Parnall Pixie was a low powered British single-seat monoplane light aircraft originally designed to compete in the Lympne, UK trials for motor-gliders in 1923, where it was flown successfully by Norman Macmillan. It had two sets of wings, one for cross-country flights and the other for speed; it later appeared as a biplane which could be converted into a monoplane.
The Beardmore Wee Bee was a single-engined monoplane built only once and specifically for the Lympne two-seat light aircraft trials held in the United Kingdom in 1924. This plane won the major prize.
The Cranwell CLA.4 was a single-engined two-seat inverted sesquiplane designed and constructed for the 1926 Lympne trials by an amateur group from RAF College Cranwell. Two were entered, though engine problems prevented one from taking part; the other was eliminated with a broken undercarriage. A third aircraft was amateur-built in Canada and flew until 1934.
The Cranwell CLA.3 was a parasol winged single-engined, single-seat British aircraft built to compete in the Lympne air races of 1925. It was designed and built by an amateur group drawn from staff and pupils at the RAF College Cranwell. Though it won one prize and set a Class record, only one CLA.3 was made.
The Cranwell CLA.2 was a single-engined two-seat biplane built by staff and students of RAF College Cranwell as an entrant to the Lympne Two Seater Light Aeroplane Trials of 1924. It won the reliability prize.
The RAE Hurricane was a single-seat, single-engined light monoplane designed and built by the Aero Club of the Royal Aircraft Establishment for the 1923 Lympne Motor Glider Competition. It was underpowered with an unreliable engine. Re-engined, it flew in many races, with first place in the 1926 Grosvenor Challenge Cup its greatest success.
The Parnall Perch was a single-engined, side-by-side-seat aircraft designed in the UK to meet an Air Ministry specification for a general-purpose trainer. No contract on this specification were awarded and only one Perch was built.
The Parnall Pipit was a single-engined, single-seat naval fighter designed to an Air Ministry specification in 1927. Two prototypes were built but both were destroyed by tail flutter.
The Short S.6 Sturgeon was a prototype single-engined biplane naval reconnaissance aircraft, built to an Air Ministry specification but mostly intended as a demonstrator of the corrosion resistance of duralumin aircraft structures. Two were made.
