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.

Hansa-Brandenburg W.12


The Hansa-brandenburg W.12 was developed in 1916 by Ernst Heinkel. It was a two-seat fighter-scout, which made its first flight in January 1917. It was a very manoeuvrable aircraft.

The fuselage was made of plywood. Noteworthy was the downward rudder, thus giving the observer a free field to fire.

The aircraft was produced with either a 160 hp Mercedes D.III as well as a 150 hp Benz Bz.II.

The first series of the production suffered from problems with longitudinal stability. From aircraft with construction-number 2000 and on this was solved by extending the fuselage.

It was a good float plane with good flying characteristics and it was used as an example for the later Van Berkel, WA.
