In Memoriam

Klaas Willem Jonker
(Wilko)
† 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.

Martin TT

History

After having built mainly aircraft with pusher prop, "pushers", Martin switched to types with a pull screw, 'tractors' in 1913.

Work on the Martin T prototype started in August 1912. It was equipped with a Gnome radial engine.

In October 1914 it was succeeded by the Martin TA (Tractor Army), with an engine of 120 hp, designed for a competition of the US Army. However it was destroyed during test flights.

In February 1914 Martin was asked to equip a Model T with dual controls in a tandem cockpit. Three Model Ts were adjusted and another 14 eaxamples were built under the designation Model TT (tractor Trainer).
