In 1927 Swallow built the Irl Beach designed two-place Dallas Spirit NX941 for the Dole Race, piloted by William P Erwin. It failed to compete, but took-off two days later as a search plane and was itself lost at sea.
Designed by Dan Lake, and built Oct 1929 by Swallow as a monoplane with a 165hp Wright as C-165 NX431N c/n 1, and relicensed as N431N in October 1930.
Sold to Dan Lake in October 1933 by the receivers of Swallow. The company name could not be used, so Lake used his own name and changed the model to C-1 as a four place cabin biplane after switching to the 150hp Hisso engine.
Sold in May 1935 to Stanley Ball of Wichita and the registration was cancelled on 1 June 1936.
In one last desperate gamble, Jake Moellendick committed all the company’s resources to building a Swallow monoplane, the Dallas Spirit, to win the $35,000 1927 Dole Prize for the first civilian flight from California to Hawaii. The Swallow monoplane was one of two that turned back, but a couple of days later during a second attempt to reach Hawaii, the plane was lost nine hours out over the sea. The Swallow Company went down with the Dallas Spirit.
Single seat single engined high wing monoplane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tail; yaw control by fin mounted rudder; roll control by one third span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile; double surface. Undercarriage has three wheels in tricycle formation with additional tailskid; steel spring suspension on nosewheel and glass fibre suspension on main wheels. Push-right go right nosewheel steering connected to yaw control. No brakes. Aluminium tube framework, with optional pod. Engine mounted at wing height driving pusher propeller.
Chet Fudge, the creator of the Swallow, named it in memory of the 1928 American biplane. Swallow AeroPlane Company (earlier called Aeroplane Marketing), originally sold two versions of this single seater, the Swallow bi-motor, which is classified as an ultralight in the United States and the Swallow B with single engine, classed as an experimental homebuilt aircraft. The twin engined ultralight used two single cylinder Yamaha KT100S engines giving 15 hp each and driving through a common reduction drive with separate clutch¬es for single engine operation in case of failure.
The company introduced another ultralight variant, this time with one engine, called the Swallow A. It uses a Rotax 277 engine.
The Yamaha engined machine was avail¬able for $5475 in kit form in 1983. Nosewheel steering, previously optional, has been stan¬dardised for the Swallow A and for the first time in the Swallow range a pod is available as an option. Other options include floats and a strobe.
The Swallow B is the same as Swallow A except: No ground steering (optional: push right go right nose-wheel steering connected to yaw control). Optional brakes on main wheels. No pod option.
In the US the Swallow B is too heavy to be classified as an ultralight, but it could come into the microlight category in some countries. It is basically the same aircraft as the original twin engined Swallow, but with a Cuyuna 430 engine substituted, developing 30 hp.
The engine is shrouded behind a distinctive glass fibre fairing, which also improves its cooling. According to the prices given at Sun ‘n’ Fun in Lakeland in March 1983, the Swallow B sells for $5790 including the engine cowling. Options: wheel fairings for the main wheels $115, steerable nosewheel $360, hydraulic brakes $388, float mountings $456.

This single-seater 15m span sailplane is designed especially for use by clubs and small syndicates, with the emphasis on low running costs and capital outlay together with safe flying qualities. Available in two forms, as the SD3-15T with a T-tail and the SD3-15V with a V-tail, the Swales was developed from the Birmingham Guild BG 135 Gipsy, the 13.5m span version of the BG 100/12 designed by J. C.Gibson, K. Emslie and L. P. Moore of Sailplane Design Ltd. Manufacturing rights of the BG 135 were acquired by Yorkshire Sailplanes Ltd, who built a batch of seven as the YS 55 Consort. The BG 135 was itself developed from the earlier and very similar Birmingham Guild Gipsy 12/15 project which, like the BG 100/12, was intended to be a low cost lightweight Standard/Sports Class sailplane in which either a medium-performance 12m wing or a high performance 15m one could be fitted to a common fuselage and tail unit. This was to be achieved by special attention to structural efficiency resulting from efficient wing skin stabilisation, with rigid foam cores, and low cost was achieved by eliminating taper as well as twin-skin sandwich or ribbed forms of construction. The prototype BG 100/12, with a 12m (39ft 4in) span wing, first flew on 7 April 1970 and, like the later SD3-15V, was a cantilever shoulder-wing monoplane of all-metal construction with a V-tail and a large hinged moulded cockpit canopy; a 13.5m span wing was later fitted.
Construction of the prototype SD3-15 began in September 1974 and it first flew in March 1975, being designated SD3-13V. The first prototype SD3-15V first flew in July 1975 and the first SD3-15T made its maiden flight in December 1976, the suffix letter denoting the tail configuration; six SD3-15s had been built by mid-1979; production was then only to order and was restricted to the T-tailed SD3-15T.
Structurally, the SD3-15 is very similar to the BG 135 and BG 100/12 from which it was developed; the constant chord wings have metal and polystyrene ribs and glassfibre reinforced plastic (GRP) wing tips, and the trailing edge flaps also act as air bakes. The plain metal ailerons have foam ribs. The metal skinned semi-monocoque fuselage has a GRP nose cone and is built up on four longerons. The landing gear consists of a non-retractable monowheel with an internally-expanding brake, and a tailskid. Both versions have a metal tail unit with 50% foam ribs; the SD3-15T has a full-span elevator with spring trim while the SD3-15V has all-moving tail surfaces with anti-balance tabs. The cockpit canopy opens sideways to starboard.

In early/mid-1930s, at Linkoping, Svenska Jarnvagsverkstaderna built Viking three-seat cabin monoplane with wheel or float landing gear, developed later into Viking II four-seater.
Before September 1964, Svardala built the prototype Svardala Bullet, 2-seater, side-by-side, flying-boat. The (plywood) hull, landing gear, (fabric-covered) wings, (fabric-covered) empennage and tip floats were similar to contemporary Volmer Sportsman and Anderson Kingfisher. The greatest difference was in in the aft cabin, which vaguely resembled a Republic Seabee. The most striking difference was the short pylon supporting the engine (Continental or Lycoming) and propeller. Because the crankshaft was only a short distance above the (flat) aft fuselage, Svardala installed a 2-bladed, wooden propeller with broad, curved blades.
The Svardala Bullet was sold during the early 1970s and moved to Sherbrooke, Quebec. The new owner complained about poor climb performance. He installed a blown Plexiglas windshield, taller engine pylon and larger diameter propeller.
Apparently, several registrations (most non-official) were tied to the Bullet, including CF-PUY, CF-SYF, CF-PUH, CF-PHU, the latter possibly being the X-1).
The SV Xl takes on the sleek lines of the SV series of aircraft from the Veenstra factory. The approach this time is to cater for people who admire the glider lines but would prefer conventional performances. The Xl will have sprung main wheels and a V tail. The owner will have the option to purchase the SV Xl without the sleek cockpit and fly in the breezy aluminium frame that is hidden under the fibreglass skin. Aircraft marketed as Mantis in New South Wales, Australia.

The SV 8 is a cantilever high wing pusher and takes on the lines of a clipped wing sail plane, constructed of foam aluminium and fibreglass, the aircraft has a fully enclosed cockpit, full span flaperons and V tail mounted on the tail boom. The single wheel undercar¬riage comes with brake as standard and the tip wheels aid ground handling. The wing unbolts from either side of the fuselage for trailering.
