Southern Aircraft Martlet
F. G. Miles developed the Avro Baby into Martlet and Metal Martlet light aerobatic and sporting types. Last example flew 1931.
Southern Aircraft Martlet Article
The first Martlet G-AAII was a modified Avro Baby powered by an 85 hp ABC Hornet. Development of the type was by the Miles Brothers, D L Brown and H Hull at Shoreham and it was first flown in August 1929. During the following two years five Martletts were built; G-AAVD, G-AAYX, G-AAYZ and G-ABIF, all with different specifications and various powerplants. It was to have been succeeded by the Metal Martlett in 1931 but this machine was scrapped after a limited amount of flying.
Southern Aero Sports Scorpion
The Scorpion was grounded by the UK Civil Aviation Authority. This followed a series of three in flight structural failures, two on single seaters and one on a two seater, which resulted in three deaths and one serious injury. Subsequent investigation by the Accident Investigation Branch revealed a lack of torsional stiffness in the main structural components, as well as a poor standard of detail engineering. The company went into liquidation shortly after the accidents. By 1982 were no longer trading.
Between 30 and 40 Scorpions were made, in various guises, all using Robin engines of either 330 or 440 cc.
Southern Aeronautical Renegade
This Formula-V sport racer features a straight-line midwing design. The design was largely based on the Cassutt Special III, but was made suitable to accept VW or VW-based engines. Its designer, Charles Lasher, has chosen steel-tube construction for the fuselage and tail because of its ability to withstand the shock of a crash better than other materials
The wings are a wood-frame structure with fabric covering. The ship is made to handle any Volkswagen from 35 to 65 hp.
The first aircraft was built by M. Ricketts and after eighteen months of construction it was first flown in 1974, registered N73RL (c/n B15). Of conventional construction with all-wood wings and fabric-covered fuselage, the single-seat aircraft was powered by one 55 hp Volkswagen VW1600 motor car engine.
N73RL took second and third places in the Formula V competition at the 1978 and 1979 Cleveland National Air Races respectively, and was used for aerobatic displays.
Plans for amateur construction were marketed via Southern Aero Corporation of Miami Lakes, Florida, after 1983 via Charles Lasher.
At least four Renegade I aircraft were completed in the USA:
N73RL, N1031A, N35DE, and N64JM (designated Michalak R-1).
Biplane Racer Andrew Buehler has set up an LLC and negotiated to acquire the design and manufacturing rights for the Renegade from Creighton King in 2014. Initial planning was for Ed Fisher of Raceair Designs to help with the development and construction of a new Renegade airframe, to use in the promotion of the design. Several minor improvements, and a new wing design were in the works.

Southdown Sailwings Puma
A Puma is a combination of the South¬down Sailwings Lightning DS wing and a Southdown Sailwings approved two seat trike unit. The first such combination used an Ultra Sports trike unit and is known simply as the Puma. Later combinations carry a suffix to show the trike unit manufacturer, viz: Puma MS (Mainair Tri Flyer Two Seater trike unit) and Puma SS (Southdown Sailwings’ own trike unit).
A Puma Sprint is a combination of the Southdown Sailwings Sprint wing and a Southdown Sailwings approved two seat trike unit. The first such combination used Southdown Sailwings’ own trike unit and is known simply as the Puma Sprint. Later combinations carry a suffix to show the trike unit manufacturer. One such combination uses the Mainair Tri Flyer Two Seater trike unit and is called the Puma Sprint Ms.
The Sea Puma is a combination of the modified Southdown Sailwings Lightning DS wing and a modified version of Southdown Sailwings’ own two seater trike unit.
Thus there is no such thing as a single seat Puma.

Šoštarko Monoplane
1911-12 monoplane of Austro-Hungarian/Croatian origin built by Slavoljub Šoštarko in Zagreb (Agram), Croatia – then part of the Austro-Hungarian Empire. Šoštarko was probably an automobile racer who crossed over to airplane design and flying, but when his monoplane was exhibited in Zagreb in 1912, it was destroyed during his very first attempt at flight. There is no evidence that Šoštarko flew after this. As one of a few others who were experimenting right next to the sheds of Mihajlo Mercep at the gates of Zagreb, to be expected, the Šoštarko monoplane shows some resemblance to the Mercep Rusjan-Novak monoplanes; i.e. wing-posts, tail assembly with rudder running through the stabilizer, etc.
Sorrell Bathtub
Built by Otto Sorrell circa 1950, the Sorrell Bathtub was a single-place, open cockpit, high wing monoplane, inspired by 1924 Dormoy Bathtub.
An “ultra-ultralight” powered by a geared-down chain-saw motor and tricycle gear, it was further developed by Michael Kimbrel, of Oakville WA, who in 1978 flew a tail-wheel version with a VW engine, then promptly sold 400 sets of drawings to home-builders.
Sorrell Colt
Built by Otto Sorrell, probably in the 1950s, the Sorrell Colt was a single-place, open cockpit biplane, powered by a 65hp Continental A-65.
