Remarks by Johan Visschedijk: "First flown on February 12, 1924, the Dornier Spatz, a land version of the Libelle flying boat, was a high-wing monoplane of all-metal design with fabric covered rear wing sections and controls. The wing area was subdivided into three sections: the two wing halves, connected to the center wing section, were braced against the fuselage by means of two struts each and folded backward, as in the case of Libelle. This reduced the width of the aircraft from 32 ft 1.8 in to 9 ft 10 in (9.80 m to 3.00 m), thereby providing good transport and storage possibilities.

The monocoque hull housed three seats, two side-by-side with dual controls and one seat aft. The power plant consisted of a three-cylinder Bristol Lucifer radial engine of 100 hp located in a nacelle on the rigid center wing section. Fuel was delivered by a wind-driven pump from a fuel tank in the hull to a gravity tank behind the engine. The tail unit was of standard design, and the aircraft had a rigid landing gear with an axle passing through the fuselage and a tail skid."
