Design and development

The DF 2000 was designed to provide a fast, robust, comfortable, low-cost side-by-side two-seat ultralight with a short take-off run. It has a conventional layout not unlike that of, for example, the Cessna 152, with a high wing, swept vertical tail and tricycle undercarriage.[1][2]

Structurally, it is mostly built from aluminium alloy, reinforced with TIG-welded 4130 steel tubing in the cockpit area. The wing has constant chord and is braced on each side by a single, broad streamlined strut from the bottom of the fuselage. The shallow, turned-up wing tips are formed from composites. Inboard flaps are fitted. The cockpit area, under the wings and fitted with dual controls, is accessed by upward-hinged doors with deep glazing. Aft, the fuselage becomes more slender, though the swept fin has a long fillet. The rudder has a trim tab and the low-set, parallel-chord tailplane carries a balanced elevator. The tricycle undercarriage has main wheels which are cantilever spring-mounted from the lower fuselage and a steerable nose wheel. All wheels are usually spatted.[1][2][3]

The DF 2000 family uses several engine/propeller combinations, mostly from the Rotax 912 series of 80 to 100 hp (60 to 75 kW) flat-4s but also the 85 hp (63 kW) Jabiru 2200 and 120 hp (89 kW) Jabiru 3300 powerplants.[2][1][3]

The DF 2000 first flew in about 2001 and went into production three years later. .[2]
