Fred G Sindlinger built the Sindlinger Special #1 in 1959. Registered N6448C, it was a single-place cabin, low-wing monoplane powered by a 65hp Continental engine, later 75hp A-75.
It first flew on 10 April 1959.

Designed by Boeing engineer Fred Sindlinger in the late 1960s, the prototype was built ahead of any drawings, subsequently put on paper by two draughtsmen – one in metric and the other in imperial. Sindlinger’s 5/8-scale version of the British Hawker Hurricane first flew in 1972. Both the wings and fuselage are constructed of wood with a fabric covering. The powerplant turns a metal constant-speed prop and is fed by a main fuel tank just aft of the firewall, with a. capacity of 14 gallons. Optional 10-gallon tanks can be built into the wing root. The landing gear is a steerable tailwheel type with the main gear retracting into the wings. The pilot sits under a sliding canopy.

Built the Sindlinger Special #1 in 1959 and designed the Sindlinger HH-1 Hurricane in 1972.
Founded in 1975 as Singapore Aerospace, adding “Technologies” into its name in March 1995; aerospace branch of Singapore Technologies Pte Ltd. and restructured in 1998, since when often referred to as ST Aero. Modified Singapore’s A-4S/S-1 Skyhawk attack jets into A-4SU Super Skyhawks by installation of new engine, minor structural modifications, substantial avionics upgrade and provision to launch Maverick missile, with initial oprational capability achieved 1992. Offered Northrop-Grumman F-5 Tiger II upgrade, has a shareholding in the Eurocopter EC 120 helicopter program, produces Boeing 777 nosewheel doors, and offers aircraft and engine maintenance and repair, and more.
The Simunek/Kamaryt SK 1 dates from 1968, when Jan Simunek began to design the Trempik (Little Tramp). Construction started in his apartment in the following year. He was joined by Jaroslav Kamaryt, who assisted with design and stress calculations. In 1975 manufacture was transferred to the Rudy Letov agricultural equipment factory at Prague. The aircraft flew for the first time in October 1979.
The Cub like machine has a welded steel tube forward section with a wooden semi-monocoque rear fuselage. Trempik’s two spar wing has a birch plywood leading edge, glass reinforced plastic wingtips, wooden ailerons, and a fabric covering. Tailplane and elevator are wooden, and the rudder is fabric covered light alloy tube.
The 75 h.p. Praga D 1 powerplant drives a two-blade, fixed pitch propeller taken from a Praga E 117 Air Baby.

The 1925 VBŠ Kunňkadlo was an amateur built aeroplane of the Šimůnek brothers.
Single seat single engined biplane with con¬ventional three axis control. Wing has un¬swept leading and trailing edges, and constant chord; cruciform tail. Pitch control by fully flying tail; yaw control by fully flying rudder, with additional fin; control inputs through stick for pitch/roll and pedals for yaw. Wings braced by struts and trans¬verse X cables; wing profile; double¬surface. Undercarriage has three wheels in tricycle formation; glass fibre suspension on nosewheel and suspension on main wheels. Push right go right nosewheel steering. Aluminium tube framework, without pod. Engine mounted level with top wing driving tractor propeller.
The aim of the Little Bi is to provide a simple lightweight fun biplane, rather than a machine with pretensions to high performance. Its framework is con¬structed of aluminium tubing, while the wings are made from styrofoam with glass fibre ribs and non porous Dacron covering.
Though initially flown with a Yamaha KT100S engine, the aircraft was sold as an engineless kit and it is up to the builder to supply a power plant. The 215 cc Cuyuna 215R with 20hp driving a 54 inch (1.37m) propeller is recommended, but a 22hp Zenoah or the Yamaha are listed as alterna¬tives, each working through a reduction drive.
Two kits are offered, neither of which involves any tube bending or welding: the fast build kit for $2845 (50 60 h) or an economy kit for $1825 (100 120 h) in 1982, the latter requiring the builder to purchase some basic materials locally. Neither kit covers anything more than the structure of the aircraft, items like seat and fuel tank being extras, for $49.95 and $65 respectively. For the builder who wants to spread the construction cost over a period, five part kits were available.
