Aviakit Vega

The Aviakit Véga is an ultralight aircraft seating two in side-by-side configuration. It was designed in France in the late 1990s to be easily constructed by amateurs from kits and was offered with a choice of three engines and of tricycle or conventional undercarriages.

Design and development

Roland Prevot started Aviakit to produce kits for home building of his two seat, side-by-side configuration, ultralight design, originally named the Aviakit Hermès. It was intended as an ultralight that could be quite quickly (300 hours) assembled by inexperienced constructors. In September 2001 production rights were acquired by PJB Aerocomposite and the aircraft renamed the Aviakit Véga 2000 or Aerocomposite Véga 2000 but the arrangement ran into financial difficulties and in June 2004 Aviakit were reformed to produce what has since been known as the Aviakit Véga 3000.^[1]

The Hermès was built from a mixture of wood and composite material but the later Véga models are largely composite aircraft. The single spar, low wing is straight tapered, with 5° of dihedral and fitted with flaps. The fuselage is wide over the wing to accommodate the seating under a prominent, two piece canopy. One of three different four cylinder, horizontally opposed engines may be fitted: the 80 hp (60 kW) Jabiru 2200, the 80 hp (60 kW) Rotax 912UL or the 99 hp (74 kW) Rotax 912ULS. The standard propeller is two-bladed, though there are alternatives. Behind the cabin the fuselage becomes slender. The Hermès had a strut braced cruciform tail and at least one Véga had a braced T-tail; later aircraft have a cantilever tailplane set low on the fuselage. Since 1998 the rudder has carried a trim tab. Beneath the tail there is a dorsal fin. The Véga has a fixed, cantilever undercarriage which my be of tricycle or conventional layout. The mainwheels have hydraulic brakes and may be enclosed within speed fairings.^[1][2]

Operational history

Thirty five Aviakit Hermès kits were produced before the Aerocomposite take-over, fourteen appearing in the 2010 European registers. These also show thirty seven Végas, all but one Aviakit Végas with just one Aerocomposite Véga. Where the model is given, most Végas are 2000s, with only two 3000s.^[3]

Vegas were exhibited at the 2001 Paris Salon and at Aero '05, held in Friedrichshafen in April 2005.
