Early in the summer of 1927 the Działowski brothers, Stanisław and Mieczysław, moved their aircraft building activities from Bydgoszcz to Kraków-Rakowice where the military unit was much more sympathetic to amateurs and allowed the use of their workshops.
Further aft the fuselage structure was a rectangular section, welded steel tube girder, with wooden frames, stringers and fabric covering producing an oval cross-section apart from a flat underside.
[1] Both fin and tailplane, the latter located on top of the fuselage, were small and rectangular in shape, mounting large, balanced control surfaces.
With their crest on the fin and assisted by the LOPP, he flew it in a series of local demonstrations to raise funds for the Działowski D.K.D.4, a new aircraft which won the 1928 second National Lightplane Contest.
Over its career the D.K.D.3 made some 1,800 flights and logged 431 flying hours;[1][2] on 1 July 1933 SP-ACR, its final Polish civil registration, was withdrawn from use.
