The French designed, Indian manufactured X-Air is a fully featured, affordable light aircraft, developed over several years and there are over 1,000 flying world-wide in 2014. The X-air is a high wing, 2 seat, side by side, conventionally controlled, microlight/ultralight aircraft, with full dual controls, toe brakes, and elevator trim. The fuel tank capacity of just over 59 liters gives a comfortable endurance of at least 3 hours at normal cruise with a 1/2 hour reserve and there was an optional 80 L fuel tank. The fuel tanks are filled at the side of the fuselage. The X-air’s layout consists of a high mounted tractor engine set up, tricycle undercarriage, and a maximum all up weight of 450kg.

The X-air is manufactured in India, and was supplied in kit form, which comes very complete. Only the choice of Engine/Prop & Instruments are required to finish it, ready for flight.

Nearly all of the exposed tubing, comes White Epoxy painted for long life, and some components come pre-assembled, e.g. Tailplanes & Elevators, and all the required nuts & bolts are in their relevant place’s, to speed up assembly.

The X-air is fitted with full Dual controls, i.e. two sticks, two throttles. Both the pilot and the passenger have their own control stick which is located between the legs. The advantage of the left seat is the use of the independant toe operated drumbrakes, fitted to the top of the Rudder pedals.

The standard and flap model X-AIR were available with three engines from Rotax-Bombardier of Austria, the Australian produced Jabiru engine and the HKS from Japan. Rotax options being the 52 HP “503” or the 65 HP “582” and the 80HP “912” with carbon fiber Brolga ground adjustable props.

The recommended engine selection is the Rotax 582. The 582 engine bolts to the X-Air without modification, it is economical, has good performance (up to 1200 ft/min climb one up, 900 to 1000 ft/min climb two up). The Rotax 503 producing 52 HP offers good performance and economy but with two heavy pilots the climb performance is about 600 ft/min. The Jabiru 2.2 and Rotax 912 engines both need to modify the engine mounts.

The seats are fitted with headrests. The cockpit floor is solid wood, lexan windscreen, and there is an optional door kit. Each wheel has its own shock absorbing system. The suspension design is similar to shock absorbers on a motorcycle and can handle all the bumps and potholes on grass and bush strips with ease. The front wheel has dual shock suspension with trailing link design steering; the trailing link design straightens up immediately on touch down, so even landing in cross wind is relatively easy in the X-Air. Steerable nose wheel, linked to rudder pedals. The shock absorber design used on the X-Air offers rebound dampening. The undercarriage is rated to 9 g’s.

The X-Air can be pulled down in about 15 minutes. Firstly, the Velcro attached wing nappy is removed, the wing skin tensioning belts are released, the aileron cable is detached and with the assistance of a helper the wing struts are removed and finally, the wings are detached from the main fuse tube. All the wing removal can be done without tools. The wing can be reattached in about 25 minutes.

The X-air came in a range of 15 different colour combinations.

In 2012 the X-Air LS was still priced at US$59,995.

World Aircraft of Paris (Tennessee, that is), offers the Vision and Spirit S-LSA (also in kit form), now with new Garmin radios and “value pricing.” The Vision is a STOL bird with outsized doors, full elevator control at steep angles of attack, and it climbs out with full flaps, sports a beefy landing gear and routinely demonstrates 100-foot takeoff rolls! Price range: $85,000 to $125,000.

The World Aircraft Spirit is a Colombian/American amateur-built aircraft, designed by Max Tedesco and produced by World Aircraft Company. The aircraft was publicly introduced at AirVenture in 2011 and production was expected to commence in 2014. It is supplied as a kit for amateur construction or as a complete ready-to-fly aircraft.

The Spirit features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit that is 48 in (122 cm) wide, fixed tricycle landing gear and a single engine in tractor configuration.

The aircraft is made from aluminum sheet. Its 32.9 ft (10.0 m) span wing has an area of 132 sq ft (12.3 m2) and mounts flaps. The wing is supported by “V” struts and jury struts. The aircraft’s recommended engine power range is 100 to 130 hp (75 to 97 kW) and standard engines used include the 100 hp (75 kW) Rotax 912ULS, 100 hp (75 kW) Continental O-200 and the 100 hp (75 kW) Lycoming IO-233 four-stroke powerplants.

The aircraft has a design maximum gross weight of 1,653 lb (750 kg), but is restricted to 1,320 lb (599 kg) if flown in the US light-sport aircraft category.

The Spirit airframe is constructed in Colombia and then shipped to World Aircraft’s facility at Henry County Airport in Paris, Tennessee for final assembly and paint. Kits shipped are fully assembled and then disassembled for customer delivery and may be shipped painted as well. Construction time from the supplied kit is estimated as 110 hours.

By December 2011 55 examples had been completed and flown. As of October 2012, the design appears on the Federal Aviation Administration’s list of approved special light-sport aircraft.

The price in 2014 was US$129,500 (assembled, Spirit Grand Edition model). World Aircraft Company announced Vision kits were to start shipping in the first quarter of 2015. The regular price was to be US$26,995.00, but with an introductory price for the first twelve kits of US$24,700.00.
