The original amateur-built category D18 was adapted to comply with the Fédération Aéronautique Internationale microlight rules with the addition of larger flaps and renamed the D185. Both the D18 and D185 feature a cantilever low wing, two seats in a side-by-side enclosed cockpit configuration, fixed conventional landing gear and a single engine in tractor configuration.
The D18 is made with a wooden structure, covered in doped aircraft fabric. The 7.50 m (24.6 ft) span wing employs polyhedral configuration with the outer wing panels exhibiting much greater dihedral. Engines used include the 85 hp (63 kW) Jabiru 2200 four-stroke powerplant as well as Rotax, Limbach Flugmotoren and 58 hp (43 kW) Volkswagen 1600 automotive engines.
