Introduction


Background*

If ever there was a nation that was painfully aware of the effect of submarine warfare, it was Great Britain. Near the end of the Second World War, it was clearly recognized that a dedicated anti-submarine warfare aircraft was needed, and the Fairey Firefly was not capable of fulfilling that role.

Specification GR. 175/45 was put out at the end of 1945 for a dedicated anti-submarine warfare aircraft that was also able to perform anti-shipping duties. Gr. 175/45 was also grounded in a technology that had been previously developed by Fairey, that was the use of two engines, each with its own crankshaft to power co-axially mounted, contra-rotating props. This had great advantage for carrier based aircraft in that there was the safety of two engines, rather than one; the engines could be mounted in the fuselage, rather than enlarging the wings to accommodate two propulsion units; and contra-rotating props eliminated the effect of propeller torque. Another advantage of such an arrangement was that one engine could be shut down to conserve fuel and extend flight time, an important factor in long-range anti-submarine patrols. With the improvements in turbo-engine design, the Armstrong Siddeley Mamba engine became the power plant of choice. When Fairey coupled two together for its proposed Type Q (the Gannet) it became know as the “Double Mamba”.

 



Development of the Type Q began in 1946, but it was not until 19 June 1950 that the first Type Q actually engaged in flight deck trials on HMS Illustrious. On that date, the Type Q became the first turbo-prop aircraft to takeoff and land on an aircraft carrier. Nearly another three years would go by until the first production Gannet AS. 1 made it debut in June 1953 and two more years until the gannet entered operational unit service with 826 Squadron in January 1955.

The AS.1 Gannet had a crew of three - pilot, observer and rearward facing radar operator. Its offensive weapons were carried in the weapons bay, which could accommodate various combinations of torpedoes, depth charges, sea mines, conventional high-explosive bombs and sonobouys. Four mounting points under the center section of each wing could be used for up to 24 unguided rockets.



Classic Airframes' 1/48 scale Gannet in the box

The Fairey Gannet is right in the middle of Classic Airframes' subject sweet spot - a 1950s Fleet Air Arm aircraft that has never before appeared as a 1/48 scale injection moulded kit.

Classic Airframes Gannet comprises 56 parts in shiny grey plastic, 29 parts in grey resin and 7 clear injection molded parts. Markings for British, Indonesian and Australian aircraft are included.

The quality of the plastic is very good, with no sink marks or ejector pins in obvious locations. Being a limited run model, however, there are no locating pins so test fitting and careful alignment will be essential during construction.

The resin parts are beautifully detailed, convincingly fitting out the three cockpits and wheel wells. The casting blocks on the wheel well and nose parts are quite imposing, so a stout razor saw or a cutting wheel attachment on a Dremel motor tool will be the order of the day.

Clear parts are free of distortion. Separate sections are supplied for each of the canopy parts, so the modeller can choose which sections to slide open and which to keep closed.

For a more detailed examination of the kit contents, see Steven "Modeldad" Eisenman's review elsewhere on HyperScale.

 

 

Construction

 

If you have built one of Classic Airframes recent larger kits such as the Anson or the Canberra, you will have a good idea of what to expect with this new Gannet.

The most important step is careful and thorough preparation of the kit parts prior to assembly, both plastic and resin. I spent around an hour and a half removing flash from the kit parts and separating resin pieces from their casting blocks.

For the large nose casting, I started by cutting a groove into the back of the part using my trusty razor saw. This gave a definite line of demarcation between the resin part and the casting block.

Once I had cut all the way around the nose part, I attached the round cutting wheel to my Dremel Motor Tool. This was used to "slice and dice" the rear of the casting block, all the time being careful to avoid intruding on the part itself. The smaller blocks resulting from the "dicing" were then ground off with the cutting wheel.

The Dremel was also used for the casting blocks on the wheel wells, rear cockpit tub and the second cockpit's radar unit. 

Test fitting the resin nose casting against the front of the fuselage showed a mismatch - the diameter of the nose was slightly smaller than the front of the fuselage. I corrected this by gluing plastic strip to the back of the resin nose part as an extension plug. This was sanded back to match the contours of the fuselage once the resin part is glued in place later in construction.

I was very pleased that the nicely detailed mail wheel well parts fitted easily inside the wing halves without the need for any further thinning. I did manage to accidentally cut through the top of one of the wheel wells with my Dremel though!

With the wings assembled, I test fitted them against the fuselage (which was taped together and fitted with the supplied wing spar).

The fit was not completely flush and the wing was wider than the wing root, so I sanded the mating edge of the wing back with a coarse sanding stick. The spar interfered with the fit too, so I sanded the top and bottom on both sides. On the starboard side, the fuselage exhaust fairing prevented the rear of the wing from fitting properly, so the top-rear of the wing was sanded back as indicated by the hatching in the photo below.

The cockpit parts were now assembled. The exact position of the side consoles is a little vague, but I managed to get it right the first time after test fitting. I found that all the cockpit components fitted exactly as they should, and the very clever method of mounting the cockpit on the wing spar worked perfectly.

The assembled cockpit was test-fitted to the fuselage to ensure precise fit. The rear cockpit is simple, but looks fine.

The only after-market addition were Reheat photo-etched harnesses.

The completed cockpits were painted using Tamiya NATO Black - actually a very dark grey. Structural elements were highlighted with a wash of thinned Lamp Black oil paint run along edges and in shadow areas. Small details such as switches and handles were picked out with a fine brush.

Of course, Murphy's Law struck after the cockpits were painted and installed inside the fuselage. Chris Hughes sent a bunch of very useful photos clearly showing orangey-red bakelite seats and blue harness straps! I later popped the seats out of the assembled model for repainting.

While still blissfully ignorant of my colour faux-pas, I glued the cockpits and the nose wheel well to the starboard side of the fuselage. The cockpit and wing spar fitted perfectly.

Note that I intentionally positioned the wheel well around 1.5mm further forward than the locating mark on the port side of the fuselage. This means that the front of the wheel well extends beyond the plastic fuselage halves. This ensured that the ducting lined up with the extended resin nose part.

Classic Airframes' Gannet needs plenty of nose weight. Before buttoning up the fuselage, I flattened some lead sinkers and glued them into the cavity between the intake ducting and the bottom of the fuselage. More weights were added when the fuselage halves are joined.

The fuselage was now ready to be glued, taped and clamped. I started at the rear, first gluing the tail halves, clamping the parts, then using Tamiya Extra Thin Liquid Cement to secure the bottom fuselage seam, the top mid fuselage and finally the upper nose seam.

All these joins were taped until the fuselage had thoroughly set. Fit was good once the parts had been clamped to eliminate any minor steps.

With the fuselage halves joined, it was time to add the wings.

The wing roots had already been sanded with a coarse Mastercaster sander, and the top and bottom of the wing spars trimmed slightly to improve the fit.

The fit at the top of the wing was very good on both sides after these tweaks.

The tailplanes were also attached. The large horizontal stablisers are simply butted up against the empennage with no locating pins or tabs, so I reinforced this important join by drilling holes in the tail plane roots and through the tail to permit the installation of a brass locating rod. There was a slight wedge-shaped gap at the front of the tail plane roots, but this would be easily dealt with using Milliput a little later on.

Now we have something that looks like a Gannet!

With both the wings and the tailplanes in place, I could figure out how much additional nose weight would be required. I balanced the model with my fingertips under the mounting points for the main undercarriage legs, repeating this test as I progressively packed the nose with more lead weights. With the nose cavity just about crammed full, there was finally enough weight to tip the nose forward.

Now the model was ready for installation of the nose, plus filling and sanding.

The fit of the wing to the wing roots was less than perfect underneath. The port side in particular left quite a deep trough between the fuselage and the wing.

Fortunately, this was easy to fix by filling with Milliput.

Milliput was also used to fair in the resin nose casting. I had earlier built up the rear of this undersized resin part with plastic card to match the contours of the plastic nose.

The forward propeller spinner very slightly overlapped the rear section, and the rear section very slightly overlapped the forward fuselage. The base of both parts were sanded back usig a coarse Mastercaster sander.

 



A few very small gaps and steps were also filled with the same batch of Milliput.

Milliput was used to fill the small gaps at the leading edges of the stabilizer roots. A smear of Tamiya Surfacer was all that was required to fair in the tailplane finlets. Note that the tall finlets should be fitted to the top of the stabilizers - the instructions are a little ambiguous about this. A tiny spot of Milliput was also applied to the front of the winglets.

 

 

Painting, Decals and Weathering

 

Primer and More Assembly

A second round of Milliput was applied before a coat of Tamiya Grey Primer was sprayed over the model straight from the can.

I find that this is an important step when building limited run kits in particular, as it will help identify any persistent gaps or seam lines, and panel lines lost during the filling and sanding stage.

All the imperfections were highlighted with a pen for later attention.

The spinner was painted prior to assembly. This made painting the yellow stripe a little easier. The green shade is a 50/50 mix of Tamiya Park Green and Gloss Green.

Before starting the paint job, I added lamps to the landing lights. These were punched circles of plastic card, painted silver and with tiny piece of white plastic rod glued to the centre to represent the bulb. A blob of two-part epoxy cement (Araldtite) was applied over the plastic circle, encasing the plastic light bulb. Once the cement had dried, I brush-painted a coat of Future over the top. The epoxy glue is nice and glossy, but the Future will protect the sheen from frosting when it is superglued into the landing light recess.

Of course, it would be easier if I could just find a local source for MV lenses!


Paint

All paint was applied with my Testor Aztek A470 airbrush fitted with the fine tan coloured tip.

Painting started with a coat of Xtracrylics Ocean Grey (a bit paler than Extra Dark Sea Grey, so a nice representation of a faded version of the upper surface colour). The black wing walks were also masked and sprayed at this stage.

Next, the grey upper surfaces were masked using various widths of Tamiya masking tape. With the large areas of Sky on these Fleet Air Arm aircraft, I find it faster and easier to adopt this "reverse masking" approach.

Alclad Magnesium was sprayed on the outer rim of the nose intake. A thin strip was then masked with Tamiya tape.

Now, Xtracrylics Sky was now sprayed onto the remainder of the airframe.

When the masking tape was removed, the camouflage finish was revealed in its stark, clean glory. Unfortunately, the tape had lifted a large section of grey paint and primer from the starboard wing's leading edge, and a smaller chunk from the top of the port wing.

I carefully sanded back this damage before masking and respraying these sections. The operation was successful, but when I removed the masking tape from the wing camouflage demarcation, it lifted a new chunk of Sky paint and primer!

So it was back the the masking tape again, but this time I reduced its tackiness by applying it to my forehead and removing it. My specialized anti-tack head did the job, and no further paint was damaged.



Decals

The model received a coat of Polly Scale Gloss acrylic before the markings were applied. I find that the Polly Scale clear finish can be more easily controlled than Future when spraying, does not run on horizontal surfaces, yet still delivers a hard, shiny finish ideal for decals.

 

 

I used the Classic Airframes kit decals, which are very thin and settled down beautifully into panel lines.

The completed paintwork was sealed with a a further coat of Polly Scale Gloss acrylic.



Finishing Touches

All the smaller detail parts were cleaned up and painted.

Because I had moved the nose casting forward, the opening for the front gear bay was slightly longer. I therefore had a choice of filling part of the gear bay or extending the length of the nose gear doors. I chose the latter. A small piece of plastic card was glued to the front edge of each nose gear door, faired in with Milliput and sanded smooth when dry.

I particularly enjoyed the painting of the nose wheel hubs - red for port and green for starboard. As it must have been pretty obvious what side of the aircraft was port and starboard, I can only assume that the nose wheel assembly was capable of free castoring, and the colours warned the ground crew if the wheels were rotated 180º. If someone has a better explanation I would be interested to hear it.

 

 

Classic Airframes' clear parts are well presented, but the canopy centre section and two sliding canopies are slightly too short. This could be addressed by adding strips on plastic to the bottom edges of the parts, but I decided to use the spare vacform canopies from Dynavector's 1/48 scale Gannet. These fitted very well.

The injection moulded windscreen and rear cockpit canopy from the Classic Airframes kit were used, as these both fitted perfectly. White decal film was cut into fine strips and used to depict the white sealing tape sometimes seen on Gannet windscreens. With the benefit of hindsight, however, these are far too wide.

The distinctively striped tail hook was masked and sprayed yellow and black.

The resin jet exhausts were first painted Alclad Magnesium, then "scorched" with a thin mix of Tamiya Flat Black and Red Brown, applied more heavily to the

The undercarriage legs mated positively with their locating holes in the wheel wells. However, the main gear legs have a slight (and accurate) forward rake. This shifts the centre of gravity slightly forward, meaning that the nose weight was now insufficient to keep the nose wheel on the ground. Fortunately, there was enough space inside the forward wheel well to stuff another six squashed lead fishing sinkers, and the nose wheel now gently kisses the tarmac - but only just!



Weathering

This was one of the most challenging weathering jobs I have ever done. I had a great deal of difficulty restraining myself from adding at least a modicum of grime to the airframe. However, these Royal Australian Navy Gannets were kept quite clean, so I resisted the temptation.

The only weathering was an extremely thin wash along panel lines on the nose and beneath the empennage, and a slightly heavier wash in the rudder hinge line. I did not even dirty up the tyres.

Apart from that, I added an oil wash to the undercarriage legs and the wheels. 

Wing tip lenses were depicted using Tamiya Clear Red and Clear Green.

 

 

Conclusion

 

It is great to finally have an injection moulded Gannet in 1/48 scale.

In common with most recent Classic Airframes kits, after careful preparation and regular test fitting this model delivers a great looking and well detailed result with nicely restrained surface texture.

As pointed out in the article text, the main issues to watch out for are fairing in the undersized resin nose casting and making sure that the cockpit parts are precisely aligned. Some filling underneath the wing roots will be necessary too.

However, none of these challenges are beyond the capabilities of a moderately experienced modeller. I would rate the degree of difficulty as similar to the Classic Airframes Dornier Do 17 Z.

Thanks to Classic Airframes for the sample.


Photography

The model was photographed in HyperScale's studio using a Nikon D70 digital SLR. Illumination was via two studio flash units - one Bowens 250 and a generic 100 flash - on stands and illuminating from a high 45º angle from each side of the front of the photography table.

 

 

The camera was fitted with a Micro Nikkor 60mm lens.

ISO was set to 250, and the manual shooting settings were 1/100 of a second at f.29. The high aperture ensures good depth of field.
