Resin kits by HA Models

For 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 sales price.

The 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.

Koolhoven F.K.43

fk43_06

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 1955.

The 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.

I 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.

The first production run of over 50 kits was sold out in the spring of 2018. Pending the interest, 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

The 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.

The 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 September 1939.

The release of the kit is planned for end 2018, beginning of 2019, and will be produced in 50 copies.

Koolhoven F.K.49A

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 1940.

The 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 Service of the Dutch Army) and with the Finnish coast guard.

The release of the kit is planned for the second quarter of 2019, and will be produced in 30 copies.

The kits are for sale at the Aviation Megastore (Luchtvaart Hobby Shop) close to Schiphol Airport, as far as they are still available.
