Dutch Modelling and Aviation

In Memoriam

Klaas Willem Jonker
(Wilko)
† April 30, 2018

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

History

Text about the development.

Versions.

The commonly used terms Fokker G-IA and Fokker G-IB are no authentic Fokker designations and in fact incorrect. These are most attributed to Hugo Hooftman.
Fokker designated the machines of the LVA, equipped with Mercury engines, as Fokker GI "Mercury". These devices differed from the prototype. Because of the bigger engine and larger propeller, the wing section between the fuselage and the engine nacelle was greater. The fuselage was also different.
The machines equipped with Wasp engines were designated Fokker G.I "Wasp". These aircraft were dimensionally similar to the prototype.
