The first flight of Glasair Aviation’s Merlin light sport aircraft (LSA) took place on April 7, 2015. For nearly a year afterward, refinements and testing took place.

Almost a year later to the day, Glasair received the certification it sought on its prototype model, allowing it to reclassify the Merlin as an SLSA (that first S stands for Special). The Merlin will sell as fully factory-built, ready-to-buy-and-fly aircraft.

Pilot and passenger have a 47 inch wide cockpit and sweeping views outside. Skylights make it that much easier to track traffic.

The Fox was designed by Hans Gigax in Switzerland in 1982. Single seat single engined high wing mono-plane with conventional three axis control. Wing has unswept leading edge, swept for¬ward trailing edge and tapering chord; cruci¬form tail. Pitch control by elevator on tail; yaw control by fin¬-mounted rudder; roll control by half 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; suspension on all wheels. Push right go right nose-wheel steering connected to yaw control. Hand actuated brake on nosewheel. Aluminium tube framework, with pod. Engine mounted at wing height driving tractor propeller.
The Fox single seater made its first flight in December 1982 and underwent a programme of test flights with the intention of obtaining certification in West Germany. It was only a prototype. Rigging and derigging take 20 minutes and when folded it is transportable on a roof rack. The noise measured on the ground with the machine flying at 492ft (150m) with the motor at maximum power is 58dB; West German regulations stipulate 60 dB maximum.

Evektor-Aerotechnik also is marketing the braced high-wing two-seat Fox (a variant of the German Ikarusflug Eurofox, with Evektor of the Czech Republic having undertaken important design work, and Aeropro of Slovakia building airframes for Fox and Eurofox).

The single-seater Comco-Ikarus Fox D is a first generation micro-light aircraft. The single-seat Sherpa I was the first motorised Ikarus micro-light aircraft and entered serial production in 1982. In 1983, the single-seater Sherpa I was replaced in production by the Fox D, an open single-seater constructed out of aluminium tube covered with sailcloth. The nose of the plane is made out of glassfibre composite as used by the 2-seater Sherpa II. The prop of the Fox D is driven by a Göbler-Hirth F263 engine.

Hans Gigax developed his Sherpa using experience acquired with the earlier Microstar, the two machines sharing a similar configuration and technology. The Sherpa made its first flight as a single seater in May 1982 and the two seater took to the air in July of the same year. Since then both have been put into production by the West German Ikarus company, under which heading we give greater detail. Briefly, however, the Sherpas are provided with a cage where the tubes form a double triangular structure ensuting excellent rigidity whilst offering considerable passive security. The aircraft also exhibits the peculiarity of having been designed from the start to be usable either as a single seater, with the seat fitted in the central position, or as a two seater, its frame being large enough to be fitted either with a double bench seat or two separate seats, the pro¬totype being equipped with a central stick.
Single seat single engined high wing mono¬plane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tall; 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; rubber suspension on nosewheel and suspension on main wheels. Push right go-¬right nosewheel steering connected to yaw control. Optional brake on nosewheel. Alumi¬nium tube framework, without pod. Engine mounted at wing height driving tractor prop¬eller.
A manufacturer of hang¬-gliders for many years, Ikarus has just acquired the licence to produce and sell the Sherpa designed by the Swiss Hans Gigax. The first Sherpa single seater flew for the first time in May 1982 and Hans made the first flight with the Sherpa two-¬seater on the way to the amateur constructors convention at Brienne le Chateau in France at the end of July 1982.
The prototype used a Konig SD570 four¬ cylinder engine of 570cc, but this was aban¬doned on the commercial versions. Instead, Ikarus chose to fit its single seater, the Sherpa I, with a twin cylinder Hirth 263R 383cc engine developing 22hp. By February 1983, Ikarus had already delivered eleven machines and in March at the Friedrichshafen show the firm announced orders for 200 machines.
The Sherpa I options include electric starter (with alterna¬tor and battery) and a package allowing the single seater to be transformed into a two ¬seater. This package contains a second seat fitted with belts, dual controls, and the Hirth 438cc engine and costs an extra DM2150.
Though very similar to the Sherpa I, the Sherpa II differs by the addition of a second seat, dual controls (on production models), structural reinforcements and a more powerful engine. Otherwise few changes are needed, as the Sherpa was designed from the outset to be a two seater. The Sherpa II can be turned back into a single seater in a few minutes and uses the Hirth 438cc engine developing 42hp. Following three pre production models built during the first quarter of 1983, produc¬tion started. A pod and instrument panel are optional.

Designed and built by Hans Gigax, the Microstar, which made its first flight at the beginning of 1981 and was shown by Hans at the annual homebuilders’ meet at Brienne le Chateau in France. The machine went on sale in 1982 from ASW, which has ceased to produce aircraft in Switzerland at the beginning of 1983. The Microstar was directly involved in a fatal accident in West Germany in 1982 which led the maker to stiffen its empennage by two additional tubes.
Having acquired the licence to build and sell the single seater Microstar as designed by Hans Gigax, the ASW company embarked in 1982 on the production of several examples as the Microstar Mark I. The distribution seems to have been very small, but at least one Microstar was exported to France, bought by the French agent of the Swiss parent company.

Similar in appearance to the Resurgam, the Rouseabout is a vastly different bird. The prototype was built by Don and Peter Adams with design consultant Gordon Bedson (Re¬surgam). It will be shortly (1985) available in two models 95.10 (std) & 95.25 which has a larger motor, wheels and beefed up structure. The high wing is a low speed high lift GA(w) 2 NASA section sporting full span flaperons which can be deployed 45 degrees. The production aircraft will be constructed of an all fibre glass kevlar fuselage and integral tail boom, and a very complete components kit is available.
