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

This type was released to succeed the Fokker C.III, which was built in a small series for Spain.
In fact it was a development from the Fokker C.I. The aircraft, in fact a long range scout, had a rather broad fuselage, with much room for the crew, who appreciated this very much.
A disadvantage was the decrease of the maximum speed

Three variants were developed:

Fokker C.IVA:
with a smaller wing span of 12,07 m;
Fokker C.IVB:
with a larger wing span of 12,91 m
Fokker C.IVC:
with a wing span of 14.28 m.

According to Fokker, the wings could be exchanged by four men within 45 minutes.

Three aircraft were sold to the USA, after a demonstration for General Mitchell. These aircraft were tested under the designation CO-4 #1 till CO-4 #3 (CO-4 = Corps Observation model 4).
One of these aircraft was completely restored to flying condition at the Owl Head Museum. (check website: Fokker C.IV flies again.)

A smaller version was the Fokker D.C.I. only used by the NEIAF.

Spain intended to built the D.C.I under license, but choose to built and use the Fokker C.IV, of which twenty were built at Madrid.

In 1924 200 aircraft were exported to Russia and in 1923 the Argentine navy ordered three aircraft equipped with floats.

In Service with LVA.

The LVA ordered a total of thirty examples in two series. The first series was delivered in 1923 and serials 550 till 563 were applied. The second series, registered 564 til 579, was delivered in 1924.
The so called "LVA-factory" (in fact the technical service of the LVA) produced one aircraft, registered 580, from delivered spare parts.
The aircraft were initially equipped with a Liberty engine rated 400 hp. This engine, when worn out, was replaced with a Hispano-Suiza 12 Jb rated 350 hp.
Some were equipped with a Hispano-Suiza 52-12i rated 350 hp, also used in the Fokkers C.VI.

The Fokker C.IV proofed to be a very reliable aircraft.
