During early 1923 the Mars I was given extensively modified wings, had the fuel and water header tanks transferred within the fuselage to lose the view-limiting cabane structure, and had a more powerful Lion engine installed, being re-designated Gloster I. After winning the Aerial Derby of 1923, it was acquired by the RAF and with float landing gear, was used by the RAF’s High Speed Flight at Felixstowe for training purposes.

The Gloster G.14 Gannet, G EBHU, was registered on August 15, 1923 to the Gloucestershire Aircraft Co. Ltd. it was designed by H. P. Folland and built for the 1923 Lympne Trials, from which it retired when its 750cc Carden two stroke engine had cooling troubles. In 1924 it was re engined with a 698cc Blackburne Tomtit, with which it had a top speed of 72 m.p.h. Although its registration was cancelled on January 25, 1928, the Gannet was exhibited at the 1929 Aero Show at Olympia.
Britain’s Gloucestershire (Gloster) Company designed, built and flew the Mars 1 single seat racer in three weeks, as the prototype for a new fighter. It won the Aerial Derby in 1921, 1922 and 1923, and set up a British speed record of 196.6 mph.

These all-metal side-by-side two seaters had retractable undercarriage and offered a ‘fighter-like” aircraft yet was powered by a small engine. Globe Swifts were priced at $2,995.
Texas Engineering & Manufacturing Co built 329 Globe Swifts under licence before Globe went bankrupt in August 1947, when it acquired rights in this aircraft. Temco priced the Swift at $3,250-3,750.

Including Globe production 1,093 were built from 1946 to 1951.
In 1989 Piper planned to produce the “sexy, spirited” SwiftFury, a 200 hp Lycoming powered 200 mph plus cruise update of the two seat Globe Swift designed in the late 1940s. Piper advised that some 350 SwiftFury orders have been placed with the 1989 price being US$118,900.00.
Global Helicopter Technology Inc was founded 1987, offers the Huey800 as a retrofit installation for the Bell UH-1 H helicopter, based on a replacement LHTEC T801 turboshaft engine, offering much-extended range.
The two-seat ‘Humming Bird’ was originally designed by William E. Hunt. It was developed in 1947 by Frontline Helicopter Corp. as the ‘Flyride’ and the prototype (N544A) made its first flight in January 1948. It was a streamlined all-metal monocoque helicopter with an automobile-style forward fuselage and forward-swept rotor pylon. Power was provided by a 125hp Lycoming engine. The engine is in the aircraft’s nose, but instead of the five controls common to conventional aircraft, the Flyride has only two primary control units: a stick with a motorcycle grip, and a throttle. The stick, which rests on an arm between the two seats, governs all movements on the horizontal plane: an accelerator of the type used in motor vehicles controls upward and downward movement by means of a governor geared to the engine, and the pitch of the blades is regulated by the engine’s output in terms of revolutions per minute.
Since the cyclic control system is replaced by a fully tilting head, the rotor has no hunting hinges or drag hinges.
Frontline Helicopter was acquired by Glenview Metal Products and the machine became the GMP-1 Flyride. Glenview Metal Products Aircraft Division includes Robert Mattox, who was formerly aircraft designer with the Pitcairn Aviation Corporation and works manager with Piasecki Helicopter Corporation. In 1954 Glenview revived the prototype helicopter designed by William E. Hunt, with Hunt himself as consulting engineer. It was upgraded with a 135hp Lycoming in 1953 and was advertised to the public as the ideal personal helicopter.

Construction of the replica Curtiss H-1 America began in the spring of 2004 and a total of 6000 man hours went into the construction at the Glenn H. Curtiss Musem at Hammondsport, New York. It has been built using the same materials as the originals with the exception of the glue and fabric covering. At Keuka Lake, New York, attempts were made to fly the replica but despite rigging changes and engine tuning it refused to fly.
The engines were then changed from the 90 hp OX-5 units to counter rotating OXX-6 of 100 hp. The aircraft then flew at Keuka Lake, New York on 13-14 September 2007, piloted by Jim Poel.
Initially referred to as the Speed Queen SQ2000, the SQ2000 was a new design following the lines of the Velocity etc., but with more rounded fuselage lines. The SQ2000 was designed by Stan Montgomery, and the prototype (which had the undercarriage of an Infinity) made its first flight in 1997 under the power of one 200hp Lycoming IO-360-C1A engine.

The SQ2000 features a cantilever mid-wing with tip rudders and a canard, a four-seat enclosed cabin accessed via doors, fixed or optionally retractable tricycle landing gear and a single engine in pusher configuration. The aircraft is made from composites. Its 26.58 ft (8.1 m) span wing has a wing area of 104.0 sq ft (9.66 m2). The cabin width is 48 in (120 cm). The acceptable power range is 160 to 260 hp (119 to 194 kW) and the standard engine used is the 200 hp (149 kW) Lycoming IO-360 powerplant.

Like many canard designs, the SQ2000 has lengthy runway requirements. The standard day, sea level take-off run is 1,600 ft (488 m), while the landing roll is 1,500 ft (457 m).
The SQ2000 lacks flaps and has a high landing speed. The overall cabin height of the SQ2000 has more headroom since the seats are mounted lower. The kit is more complete as it uses molded wings and canards.
Several examples had been completed and flown by 2005, including one by Mr. Paul Lee with one 200 hp Franklin 6A-350-C2 engine and one by Mr. David Kanson with one 200 hp Lycoming IO-360 engine.
SQ2000 aircraft were observed with Velocity style undercarriage (retracting into the fuselage) and with a KLS-developed undercarriage, which had straight undercarriage members retracting inwards into the wings.

Several models were planned for amateur construction and available from Glassic Composites, LLC, which planned various models: the SQ2000 XP, similar to the SQ2000, but with lower empty weight and suited for 150-200hp engines such as one Lycoming O-320 or Lycoming O-360 series (one example seems to have been built but probably not completed); the SQ2001, a three-seater with a passenger in the rear of the cabin; and the SQ2002, a so called 2+2 version with children’s seats. Yet none of these variants was built, and when
The SQ2000 was available with fixed or retractable undercarriage. The basic structures are moulded with spars. The SQ2000 first flew in 1993. The kit price in 1997 was US$22,000 for the SQ2000, and US$34,900 for the SQ2000 XP.
Less than a dozen aircraft were either completed or in construction in 12 years, and only eight on the US civil register. One reason probably lies in Glassic’s lack of credentials and the subsequent takeovers of the company’s assets.
Known completions are; SQ2000 N10736 (prototype), N416, N330DW, N2396M, N2366R, N206SQ, and N440DH. SQ2000 XP N971CL and the Rotor-EZ N2992P.
Glassic Composites ceased its activities and as of 1999, and was taken over by KLS Composites, a company formed by SQ2000 builders Messrs. Keith Register and Stan Montgomery.

Intended to succeed the Mosquito B, the 15m span Glasfliigel 304 single-seater is a new design very similar to the Mosquito, work on which began in the autumn of 1979 by a team under Martin Hansen.
Construction is of glassfibre, with no carbon-fibre employed, although the 304/17 (now known as the Glasflugel 402), which has detachable wing tips to give a span of 17m, has largely carbon-fibre wing tips. It employs a new 16.4% thickness/chord ratio wing profile developed by Akaflieg Braunschweig and extensively tested and refined on a Mosquito. It features Glasflugel trailing edge dice brakes and interconnected variable camber flaps, a parrallogram control stick, T-tail with fixed stabilizer and elevator, and automatic connection on assembly of all flight control. The fuselage is similar to the Mosquito’s but with a more pointed nose; the monowheel is retractable. The instrument panel can be tipped up, together with the front-hinged upwards opening canopy, with which it is integral, to allow the pilot more unobstructed entry. Up to 253lb of water ballast can be carried.
The prototype, D-9304, first flew on 10 May 1980. Production of the 304 started in the spring of 1981.

Long term plans for DG Flugzeugbau were to design and construct a a two seater glider, the DG-1000 – and from 2009 on the DG-1001. The Airfoil is a laminar wing section designed by Horstmann/Quast from DLR Braunschweig. The Technical University of Delft completed the design with the addition of winglets and optimizing the wing- fuselage intersection. The wing section is slightly less efficient at best L/D, however much better above 160 km/h. This was combined with very docile stalling characteristics and low bug- and rain sensitivity. The DG-1000 can be flown with 2 wing-spans. For easier rigging each wing features a parting device at about the 17.2 meter point. For flying at the 18 meter span a set of 0.4 meter long wing tips with “miniwinglets” are added (similar to the standard DG-800 18m tips). This configuration is designed to produce good rolling qualities and predictable flight behavior. For cross-country flying the 20m wing tip extensions with integral winglets are added. In addition the four-part trapezoidal wing of the DG-1000 has a small advantage over a two-part trapezoidal plan form at low speeds. The wings of the DG-1000 wing are about 89 kg. The fuselage incorporates a high seating position of the rear seat and a two-piece canopy. The landing gear has a shock-absorbing, new mechanism providing high comfort. One wheel extends forward from the landing gear compartment beyond the centre of gravity. The DG-1000 therefore tends to sit up, even with a pilot in the front cockpit. The sudden pitch up on winch launch is avoided because the glider always rests on the tail wheel. The big spring gives comfort during taxiing and the wheel comes with a hydraulic disk brake. The higher weight for the tail wheel is easy to handle with a towing device made by COBRA-Trailer. The sailplane has been designed with new profile sections and optimized to the size of the wings. There is a compartment in the vertical fin for ballast weights which is accessible via a removable panel. The wing-fuselage intersection was optimized for optima lboundary layer conditions with special airfoils in this area. Winglets are standard for the 20m span which performance-wise will result in a wingspan of approx. 21 meters. The drag of the nose wheel has been eliminated. From the beginning the DG-1000 was planed with an engine – as a self-launcher or as a Turbo-version. The maiden flight did not occur until July 28th, 2000.
The DG-1001S is the standard model with a 20 m span, winglets, retractable main gear, trim box, and water ballast. Additional there is an option for the landing gear of the DG-505 Orion.
DG-1001S-18/20 For this variation wing tips for an 18 m wingspan are available. 1.4 meter extensions, including winglets are available as options. In this version the DG-1000 is a very good aerobatic trainer. The extensions transform the ship into a high-performance cross-country machine.
DG-1001S Club A less expensive entry model, the span is fixed at 18 m, the gear is non retractable, and there is no water ballast system. The Club Model can be ordered with “normal” retractable gear, water ballast system, and with removable tips. This gives the option of later adding the wing extensions, including winglets thus giving a complete DG-1001S-18/20m.
DG-1001T The motorized version as a Turbo with a wing span of 18 or 20 m was available since spring 2005. The DG-1000, with the help of the trim box and fin tank, can be set up with a suitably rearward C.G. for spin training.
DG-1001M The motorized version as a Self Launcher with a wing span of 20 m was available since autumn 2009.
