a number of models I have produced resin kits under the brand name HA
Models since 2018. Subjects are airplanes of Dutch designers and
producers, for which no kit is avialable, and for which I could
identify sufficient clients in advance to recover the production cost.
These clients share the risk by ordering and paying kits
prior to release. In exchange they get a discount on the commercial
masters for the kits are made with the same techniques as I use for
scratchbuild models, and reports on the development process can be
found on this website. Up till now the following kits have been
produced or are in the design or production phase.
The Koolhoven F.K.43 was a design of 1931, produced
until 1938. The F.K.43 was of mixed construction with a wooden wing, covered
with plywood, and a steel tube fuselage, the aft part covered with linen, the
cabin part with ply and a metal sheet cowling. The F.K.43 has served
satisfactorily with the KLM from 1932 to 1940 as a trainer and taxi plane and
several private customers used it as a touring plane.
One aircraft, the PH-ASN, survived the war, as it escaped after the
capitulation on May 15th 1940 to England and served with the R.A.F.
as liaison aircraft. It has been returned to the KLM in the Netherlands in
November 1945 and flew with the National Flying School in Rotterdam as PH-NAU until
September 1952. It was also used by the Delft University of Technology for
research in the field of boundary layers. This aircraft, registered as “965”,
was also one of the two that were requisitioned by the ML (Militaire
Luchtvaart, Military Air Force) prior to the war. The aircraft was scrapped in
kit contains 33 resin parts, pieces of styrene and brass rods and sheet
to complete the model, a sheet of transparent plastci for the windows,
several templates to facilitate the construction and of course a scale
drawing and a booklet containing building instructions. Decals are
included to build six different versions of the aircraft.
have built myself the post-war NLS version, mainly to check whether the
kit could be built easily. I tested the correction for an incorrectly
engraved wing panel line, which I noticed too late (the moulds had
already been made and production was running). A second improvement was
to make the pins at the top of the main landing gear struts a couple of
millimeters longer to obtain a more natural attitude of the model.
Nico Teunissen has built the Koolhoven F.K.43 in its 1939-1940 Military Air Force livery.
first production run of over 50 kits was sold out in the spring of
2018. A second production run is planned for end
of 2019. This will include a corrected wing panel line and updated building instructions.
Koolhoven F.K.49 has been developed on request of the Dutch Ordnance
Survey (Topographische Dienst, TD) and the Air Service of the Dutch
Army (Luchtvaartafdeling, LVA) and was operated by the LVA. The
aircraft was developed in 1934-1935, motorized by two De Havilland Gipsy Major engines of 135 horsepower and was equipped with an on-board dark
room. It had dual controls, so it could also be used for training. It
accommodated a crew of four, a pilot, a navigator or second pilot, a
photographer and an assistant photographer. The aircraft with a very
characteristic angular forward fuselage was bought by the LVA, made its
first flight on September 22, 1935 and was registered as 950. It was
used for reconnaissance and photography missions by the LVA and was
operated against direct operational cost by the LVA for the Ordnance
Survey for cartography missions. It has been scrapped after the German
occupation of the Netherlands in 1940.
kit contains 58 resin parts and one vacform clear plastic part, pieces
of styrene and brass rods and a piece of styrene sheet
to complete the model, a sheet of transparent plastic for the windows,
several templates to facilitate the construction and of course a scale
drawings and a booklet containing building instructions. Decals are
included to build two different versions of the aircraft as it has
flown with the LVA prior and after
I have built the prototype to establish the best assembly order and to generate the picture for the instruction sheet. The kit has been released in March 2019, and has been produced in over 70 copies.
The F.K.49 has been developed in three versions with more powerful
engines, which were assigned the designation F.K.49A. The second one,
an ambulance aircraft for the Finnish Coast Guard with Hirth 508C
engines of 285 hp, it the subject of this kit. It accommodated five
people: the pilot, a radio-operator, a nurse and two patients on
stretchers. The aircraft could be
equipped with a wheel or (EDO) float landing gear and made its
first flight on November 3, 1939. It has flown for some time in the
Netherlands with floats and orange triangles under the military
registration 1001 before it has been delivered to Finland in January
kit contains 52 resin parts and one vacform clear plastic part, pieces
of styrene and brass rods and a piece of styrene to complete the model, a sheet of
transparent plastic for the windows, several templates to facilitate
the construction and of course scale drawings and a booklet containing
building instructions. It allows to build a version with wheel
undercarriage and a version on floats. Decals are included to build two
different versions of the aircraft as it has flown with the LVA (Air Department of the Dutch Army) and with the Finnish coast guard.
The kit has been released in August 2019, and has been produced in 55 copies.
Spyker V.2 was the first military trainer designed and produced in the
Netherlands. It was developed for the Dutch navy and the Air Department
of the Dutch army in 1917-1918. The design borrowed heavily from the
Sopwith 1 1/2 Strutter. 78 aircraft were produced and the V.2 remained in service until 1925.
kit contains 50 resin parts, a piece of clear plastic part for the
of styrene and brass rods and a piece of styrene to complete the
model, several templates to facilitate
the construction and of course scale drawings and a booklet
building instructions. It allows to build versions with three
different vertical tail planes. Decals are included to build seven different versions of the aircraft as it served with the LVA and the MLD.
The kit will be released in March 2020, and has been produced in 51 copies.
kit contains 51 resin parts, of which one is clear resin for the cabin
top part, a piece of clear plastic part for the window in the door, pieces
of styrene and brass rods and a small piece of styrene to complete the
model and of course scale drawings and a booklet
building instructions. It allows to build versions with three
different vertical tail planes, two different landing gears and two different exhausts. Decals are included to build two different versions of the aircraft as it served with the LVA . The
masters of the kit have been completed, the prototypehas been built and
the kit is now in production. The first couple of kits went for sale in August
Fokker S.IIa ambulance plane was a conversion of the Fokker S.II
trainer, designed and constructed by the LVA (Dutch Army Air
Department). It accommodated the pilot, a nurse and one patient on a
stretcher. The first flight took place in February 1932 and the
aircraft served untill May 1040. In that period
it was used rather intensively, especially for the transport of
patients requiring fast medical assistance or when the weather
prevented other transport to the islands in the north and the
middle of the Netherlands. It finally fell into the hands of the
German occupation forces and disappeared without trace.
Jan Holwerda has built the S.IIa as it served the isle
Schiermonikoog in the North of the Netherlands on its first flight
for emergency transport to the hospital in Groningen on December 8th 1933. It completed his collection of aircraft that provided this service during the years up till now.
Q.E.D. the yacht of Tony Fokker
An usual subject for this site, but nevertheless a Fokker design. The
yacht was designed and constructed in 1938 in the USA and incorporated
many aircraft construction techniques and materials. A fire destroyed
it in 1939 and the ship sank.
The project is a special one for the descendants of the Fokker family
and the group of Fokker enthousiasts, that regularly visits the traces
Fokker left in history.
The kit contains 45 resin parts, a transparent canopy, photo-etched
parts for the the small components, paint masks and an instruuction
booklet. A limited number of kits is still avaiable at the Aviation
Megastore and at Naval Models.
De Schelde S.20
kit contains 34
resin parts, a transparent vacuum formed canopy, paint masks, decals,
an instruction booklet, a 1/72 scale three view drawing and some
styrene and brass material to complete the model. It allows to
build two versions of the aircaft with engine cooling
configuration. Indications are given to build a model with extended landing flaps.
De Schelde S.20 was designed by Slot for the De Schelde shipwarf, which
had a small aviation department. It was a foour seater sports and
training aircarft with dual controls. The S.20 first flew on March 29th
1940 and until May 1940 flight tests were performed, during which the
undercarriage and engine cooling configuration of the plane was
frequently changed. What happened to the aircaft during the German
occupation is unknown. The S.20 had a nosewheel, a retractable
undercarriage, dual tail booms and a pusher propeller. The
wooden wing had flaps on the inner wing and fixed Handley Page
slots at the wing tips to prevent early tip stalling. The tail booms
were made from aluminium, as was the fuselage, which was however not a
stressed skin construction, but metal panels mounted on rather sturdy
frame profiles. The engine was a 160 hp air cooled Hirth HM 506A with
six hanging cylinders in line.
kit is an upgraded and corrected version of the VAMI kit and contains
38 resin parts to produce three different variants, a piece of styrene to produce the control horns, a piece
of transparent plastic for the windscreens and a decal
sheet produced by Arctic Models and which allows building 8 different versions of the aircraft. The
instruction sheet gives an illustrated summary of the steps required
to build the model. The kits have been released beginning of August 2023 and are for sale at the Aviation Magastore.
two seat Koolhoven F.K.20S was an aerobatic version of the
trainer, extensively used by the Nationale Luchtvaart School (NLS,
National Flying School) in the Netherlands in the 1930's. It also
flew with the Dutch Army Air Department (LVA). The aerobatic version
made its maden flight in February 1937. It was demonstrated for and
tested by the LVA, but not ordered. This aircraft finally ended up in
the Dutch East Indies. After some improvements two aircraft were
ordered by the NLS and used extensively for training. A fourth copy was
demonstrated in South Africa and was requisitioned by the South African Air Force.
The last copy, represented in the picture above, was requisitioned bij the LVA, at that time renamed
Militaire Luchtvaart (ML, Military Air Force) and flew with orange
triangles in 1939-1940.
kit contains xx
resin parts, It allows to
build versions of the aircaft with two different undercarriages and two different cockpit configurations. The decal sheet contains decals for 10 different aircraft. The masters for the kit are being build.
Pander E was a two seat sequiplane, specifically designed for basic
training. It first flew in February 1926 and was ordered in by the
Rotterdamsche Aero Club (RAC), the first of its kind in the
Netherlands, as a training and touring aircraft. Quite soon afterwards
the aircraft were transfered to the Nationale Luchtvaart School (NLS,
National Flying School), 100% owned bij the RAC. There it became
the standard training aircraft until the arrival of the Koolhoven
F.K.46 in the early 1930's. In addition the aircraft were being used
as touring plane by RAC members.
Other kits or parts
I have produced some items for my "normal" scale models, which have
been issued as separate kits or parts or as parts of kits marketed by
Fokker 60 propellers.
For my 1/144 Fokker 60 model I have bought 3D printed propellers with
blades in feathered position, as they were always in this position when
the aircraft was on the ground. A set of these propellers has been
casted in resin and are for sale at the Aviation Megastore.
Thanks to the use of a special resin the blades are also much thinner
than those in the original kit.
KLM Fokker F.VIIa decals
For the 1/72 Fokker F.VIIa kit of AB Models I have drawn decals for the
aircraft in service with KLM, starting from the decals for my F.VIIa
model modified from the Novoexport F.VIIb/3m kit. The decals have been
printed by Arctic Models and have been included in a special issue of
the kit by the Aviation Megastore.
Dollies for the MPM Fokker T.VIII-w model
I have made dollies for my own 1/72 Fokker T.VIII-w model of MPM and
have produced masters for resin copies of them. They will be produced
by Tilly Models.
Fokker S.13 Universal Trainer propellers, cowlings and decals
A set of decals for the civilian red and white PH-NEI livery. And a set
of corrected prpellers and cowlings. Available at the Aviation
