F-86 Sabre in 1/72 scale: kit building reports

1/72 page F-86K Kaasjager

After the second world war, the Korean war saw the first American wartime usage of a jet, starting with the Republic F-84 Thunderjet. But the most wel known jet fighters in Korea were the American North American F-86 Sabres that fought against the first operational Russian jet fighters of Mikoyan, the Mig-15. 

  (Sabre at a pole, which I photographed at the Dutch Airfield at Teuge in 2010) 

The F-86 Sabre was also the first American jet fighter with a swept wing. After the second world war, using German experimental data and seeing the German high speed aircraft designs such as those of Messerschmitt, the swept wing was the solution to air compressibility challenges that blocked aircraft flying faster. 

So the swept wing was introduced on the Sabre and the first Sabres were used in the Korea war. Of the Sabre, several variants were developed, with the F-86E being a capable aircraft. The F-86F had first the same wing but later introduced the larger 6-3 "F-40" wing. This wing has enlarged chord in front of the forward spar in the wing slat area and also extended wing span. A wing type can be distinguished quickly looking at the pitot tube: the later "F-40" wing has "straight" pitot tube that sits a bit more inboard than on the old smaller "F-30" wing. 

Later on, an entirely different Sabre airframe was developed with a new fuselage, this being the F-86D Sabredog with a radar nose and much fatter fuselage and a larger tail. It was deployed by the USAF and had a retractable rocket pod below the fuselage in front of the wing. The F-86K "Kilo" was a development of the F-86D with four 20mm cannons, improved electronics with the simpler MG-4 system. (The F-86D had sensitive systems and was only later released for export). These cannons required that the fuselage of the F-86K was stretched 8 inches. The first F-86K was delivered in 1955 to especially European NATO countries including 63 planes for the Royal Netherlands Air Force. It was called in Dutch the "Kaasjager" and many were licensed built from North American by the Italian FIAT company.

Two wing types were used on the F-86K: initially when introduced the old style "F-30" wing was used common to the F-86D and F-86F-30. Later starting in 1960, many Sabres got a larger "F-40" wing including the modernized F-86F-40 and F-86K. 
The Dutch F-86K when delivered had the small wing, but later beginning 1960 got the modification with a larger "F-40" wing; 
For the F-86K, in 1961 the PHILCO-FORD / RAYTHEON GAR-8 ( later called AIM-9B Sidewinder) missile capability was added as well with 2 extra pylons and electronics.
When making a model of a Dutch F-86K one can thus pick an early type "F-30" wing or a later type "F-40" wing.

(1) AIRFIX KIT:  F-86 Sabre

Airfix issued a brand new 1/72 scale kit of the F-86 F/E(M) Sabre in 2010 and it is a simple, cheap and good kit (no. A03082). Although not having all the finesses seen in many other kits nowadays, the basics are all there and the result will be quite good. It has the larger 6-3 wing, without leading edge slats.

Also, the decals are excellent with markings for... 
[A] the well known USAF F-86F "The Huff" of 39th FIS at Korea in a metal scheme. 
[B] an Italian F-86E Sabre of 4th Storno of the year 1958 with a NATO camouflage scheme. 


The kit was also issued by Airfix in another box (no. A03083) for a Canadair F-86 Sabre F.4  with different decals:
[C] Canadair Sabre F.4 No.112 Squadron, Royal Air Force Germany, during exercise "Carte Blanche", Geilenkirchen, Germany, June 1955
[D] F-86E(M) Sabre Jugoslovensko Ratno Vazduhoplovstvo of the Yugoslavian Air Foce, 1965

For both issued kits parts are almost the same: 

- the number of parts is about 60 with a nice touch the option to set open the gun ammunition load doors with pilot step.

- nice recessed panellines although there are not that many of these. 

- the cockpit could be detailed a bit more, inserting a better seat or an after market seat would be a simple but good improvement.

- looking at the ailerons, I feel that the aileron chords are a far too wide. Filling the panel line and rescribing the aileron leading edge panel line 2 mm more towards the trailing edge solves this.

- there is not a very deep intake tunnel, but it is sufficient. I simply painted the rear inside end black.

For the rest, it is a very simple kit. The indicated build sequence can be followed, so starting with cockpit, next the fuselage, wings and so on. Only minor filler was needed in some places. 


The first kit will be made as a Royal Air Force Sabre F.4 model.

Below the filled too wide ailerons are filled and rescribed:


The filler used here is white Alabastine car filler but any filler will do. 

.
Below the rescribed aileron edges can be seen...

After filling, drying and sanding, the model could quickly be given a first base light grey coat to check for any flaws.

.. and upper view, note the re-scribed aileron edges. 


For the colour scheme, it was decided to do a standard European NATO camouflage scheme Sabre. (many metal coloured F-86 Sabre older models already being in the collection building the old Matchbox kit, Heller kits and the much better Fujimi kits still in the stash).

The NATO camouflage colours of the nineteen fifties and sixties are usually... 
Dark green FS 22662 
Dark sea grey FS 22090 
PRU blue undersides FS 22602  (note that other NATO air forces often have light grey or natural metal undersides). 

In my enamel paints box, I found the old HUMBROL "authentic colours" HX1 Dark green, HX2 Dark sea grey and HX3 PRU Blue. I suggest otherwise using Humbrol respectively HU163, HU125 and HU124. 

First, the PRU blue was airbrushed on the under surfaces. After at least 48 hours drying time is needed for the old enamel, masking was done on the PRU blue with low tack tape of TAMIYA. 

Next, it was time for the camouflage. I started first be sprayed the upper surfaces a coat of Dark sea grey. After again 48 hours drying time, masking was needed for the Dark green. 


In order to get soft demarcation camouflage patterns, on 1/72 scale, PrittPoster Buddies  can be used. The use of poster buddies raises the mask a bit above the surface, so when airbrushing you get a softer edge.
It is a tacky material found in book stores that is used to fix photo's, papers etc. It can be rolled in long strings. using the Modeldecal instructions, the camo pattern is known and the strings fixed onto the model. The grey areas covered with paper and tape and the model is ready to receive its third coat of Dark green. 


and the result...


Now some detailling was needed in the cockpit area. Some bits and pieces of plastic were used here. 

The undercarriage bays are natural metal, as well as the gear legs and wheel hubs. Tyres are tyre black. The cockpit interior is medium gull grey with red seat head rest. The seat base and frame is grey.

The decals in the Airfix box (no. A03083) for a Canadair F-86 Sabre F.4  of No.112 Squadron, Royal Air Force Germany, during exercise "Carte Blanche", Geilenkirchen, Germany, June 1955, were picked for this model.

For the colour scheme, the standard European NATO camouflage scheme was used here with Humbrol paints.
Dark green FS 22662 
Dark sea grey FS 22090 
PRU blue undersides FS 22602  (note that other NATO air forces often have light grey or natural metal undersides). 

Before applying the decals, a gloss coat with JOHNSON FUTURE/KLEER was applied with the airbrush.

The kit decals went on OK, but I had to take care of the roundel at the airbrake which was set opened up. It needs trimming in a few bits. 

Final touches were:
- fin tip was painted medium grey
- making a small hole in the rear canopy fairing
- adding pitot tube
- the undercarriage
- set the opened airbrakes

This model sits nicely in the RAF collection in 1/72 scale.
