DKD-VII

 

In 1929-1930 the Działowski brothers designed the three-seater sports planes DKD-VII and DKD-VIII (differing only with engine: Siemens 55hp or Genet 80hp respectively), however aerodynamic trials at Aerodynamics Institute in Warsaw exposed numerous shortcomings of the design and further work was cancelled.

 

In 1930, the construction of DKD-VIII began as a high wing aircraft of mixed construction.

 

Suspension of support for the project and lack of financial resources, as well as the constructor's interest in the new project (DKD-X) resulted in discontinuation of works on DKD-VIII.
