The DAR 6 was a 1930s Bulgarian two-seat basic or advanced biplane training aircraft.

Design and development

The DAR 6 was designed by Zevtan Lazarov. It was constructed by the Bulgarian State Aircraft Workshops (DAR).

The aircraft was a conventional biplane with a fixed tailskid landing gear. It was powered by a radial engine.

Three versions were initially developed:

• Basic training version, powered by an 85 hp (63 kW) Walter Vega engine;
• Advanced training version, powered by a 145 hp (108 kW) Walter Mars I engine;
• 1937 Model DAR 6a. This variant offered faired struts and redesigned divided landing gear. It was powered by a 150 hp (112 kW) Walter Mars I engine.
