The DAR 21 Vector II is a Bulgarian ultralight aircraft, designed and produced by Aeroplanes DAR, first flying on 1 August 2000.[1]
When it was available the aircraft was supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[2]
The aircraft was introduced in 2001 and production apparently ended in 2014, as by that year the aircraft was no longer advertised for sale by the company.[1][3][4]

Design and development
The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced high wing, a two-seats-in-tandem enclosed cockpit, conventional landing gear and a single engine in tractor configuration.[2]
The Vector II has riveted stressed skin made with 1050 and 3105 aluminum sheet for corrosion resistance. The fuselage has a square cross-section. Its 9.2 m (30.2 ft) span wing employs flaps that can be set to 15° for takeoff and 30° for landing. The standard engine available is the 64 hp (48 kW) Rotax 582 twin-cylinder, liquid-cooled, two-stroke powerplant, with the four-stroke 80 hp (60 kW) Rotax 912 optional. Solo flight is accomplished from the front seat.[2][5]
Variants

- Standard version with bungee main landing gear suspension.[2]
