In Memoriam

Klaas Willem Jonker
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.



The DFW CV, a two seat explorer, was the successor of the DFW C.IV.
It was by far the most German-built aircraft during the first world war, there were approximately 2000 examples built by DFW themselves plus an approximately 1250 units licensed by Aviatik as Aviatik C.VI, by Halberstadt, by LVG and also by Schütte-Lanz. The aircraft was also built in Bulgaria as Uzunov-1.

The DFW CV was a composite construction, the hull was made of wood, the wings consisted of two wooden beams and were covered with linen.
The upper wing had a larger wingspan, especially by the ailerons, which stuck out.
The exhaust pipes pointed upwards like chimney, however, the machines built by LVG had a horizontally positioned exhaust. The radiator was split and positioned on both sides of the hull, later models had a radiator in front of the wing.
The wooden propeller had a diameter of 2.80 m.
