War Stories



The modelling hobby loves militaria. Planes, tanks, ships, artillery, it's like the modern day hand down of toy soldiers in the days when war games were played on back lawns. Okay, that's an oversimplification, and we build our chosen thematic material for many different reasons. A love of aviation, memories of service life, tribute to those who have served, a fascination with a time or place... I tend to look on the military equipment I model as elements of history, both the social and political history of the world and the history of technology itself. Also, the subjects we model, if they are true to life and have any accuracy at all, have stories behind them, or real human lives and dangers, not just of glue and paint.

During a recent group build on the FineScale Modeler forums, three aircraft were presented by one builder, including a brief backstory for each – the historical reality of the subject matter. That crystalised the concept for me, that each and every model we build has its story. Every time someone completes a model of the Bismark or Hood, they are retelling the terrible hours in the Davis Strait when those ships duelled. When we put the finishing touches to a favourite aircraft type in the markings of an ace, we are remembering the exploits of that pilot. The same with tanks, whatever markings you settle on, for whatever reason, whether aesthetic or due to historical research beforehand, we are recalling the actions of that vehicle and its crew, valorous, victorious or otherwise.

I was struck by the degree to which the vast range of subject matter presented to modellers today is a catalogue of the ephemeral: the markings this aircraft wore for that six week period, the equipment fit that tank carried during that particular action, the camouflage scheme experimented with on ships during those months of that year... And there is the personal record.

I'm a big fan of the Bf 109 and have collected a great many decal sheets detailing the history of the type in the various theatres of World War II, and while there are markings for victorious aces who survived the war (Galland, Hartmann, etc.) there are many schemes belonging to aircraft that went down and pilots who did not survive. This became very clear when I read through the notes accompanying Eagle Strike sheet #48078, Jagdwaffe over the Sahara, a collection of Bf 109 F-4 decals. Every one of the five aircraft depicted on the sheet was lost (that in itself is not ultimately surprising), and at least three of the pilots died, possibly all five, it was not absolutely clear from the information given. It's this latter that strikes a chord. The lives that were bound up with the machines, invested in the necessity of the moment, the imperatives of the politics of the age, and which went the way of millions.

If one builds a model of the Arizona, one is remembering the dreadful death-toll in her torpedoed hull. The same with the Yamato, as well as the courageous actions that preceded the coming of the end. Tiger tanks are ever-popular, but by 1944 they were not the invincible rolling fortresses they had been, and crews died by the bushel. To build a diorama of vehicles marked for units at the Battle of Kursk, whether German or Russian, is to recall, with hopefully a due sombreness, what is by many criteria the largest and perhaps the most terrible set-piece battle in human history.

So when critics of the hobby point with a certain negativity to its fascination with military subjects, rather than with the branches that build, cars, trucks, trains and airliners, I reply thoughtfully that the hobby celebrates courage and maps the course of technological development, while also serving as a reminder of the past, which is, of course, one of the best ways to escape reliving it.

Breaking Your Dragon Virginity



Over the years I have noticed a certain progression in armour modellers, from easy scales to more challenging ones, and from easier builds to the more difficult. Dragon is a case in point, a company which from its inception some twenty years ago set out to find unprecedented detail levels through complex plastic engineering.

Many modellers call building your first Dragon kit 'breaking your Dragon virginity,' and it seems to be a somewhat accurate notion, but to be fair there is Dragon, and there is Dragon.

I have in fact already built two early Dragons, both Russian armour reboxed by Zvezda, and I was frustrated by a trend toward too many small parts and too few positive location devices. I did not really count these as they were from the company's first five years or so, and any firm goes through an evolution in approach and engineering.

I'm rating Dragons's StuG III Ausf. F/8, in the old Imperial Series, as my first genuine Dragon, and this is perhaps a less than perfect first choice as the Imperials are known for being both complex and, by many standards, over-thought. The object was to create the maximum number of variants from the same set of moulds, resulting in a huge number of parts in any box, with many sprues in common between kits and scores of parts unused on any particular project. For instance, though this is a Sturmgeschuts, there are enough parts to construct a Panzer III turret in the box, along with many other elements. My impression is that if I was to carefully inventory what unused parts I have and buy a batch of bits through Dragoncare (if they're available), I could more than likely build a Panzer III as well.

To look at the plethora of individually bagged sprues in the box is an impressive experience, then you start to build and inevitably compare the engineering with other firms and eras. The large number of parts is derived at least in part from tiny details being molded individually rather than as part of larger units, but as some variants have such details and some do not, you find either holes to open as locators (if you're lucky) or merely raised lines to indicate where the parts go. In any other context I would have rated the latter as very amateurish indeed, especially in view of the very high shelf price Dragon has always commanded. If you're paying the big bucks you expect less of a fight and better fit.

The superstructure is a case in point. Individual panels in the roof cater to the evolution of the StuG's fighting compartment so that a common core casting can be detailed for a number of marks, but the fit of those parts is far from great. While cast detail provides tight panel lines and rivet runs in some places, separate parts conjure gaps only an inch or two away which would have been fatal flaws in the real machine. Likewise, the engineering of the canon mount is weak, a multi-part structure to which the gun will glue at the end of assembly but which depends totally on the strength of your adhesive to hold the pivots in place in a friction-fit. I reinforced the assembly with strip styrene and superglue to be a bit more confident of the canon not simply falling out one day.

And what do you do when two parts are trying to occupy the same space? The instructions are not sufficiently explicit on assembly order, the way that details crowd around the superstructure and relate to the hull top, and a strip on the glacis (bullet splashguard?) which is supplied with a locator tab and slot was around 1mm too close to the superstructure for the frontal armour to fit. After filing and fiddling for a while I shrugged and ground away the strip's locating tab. It can lie 1mm forward of where it's supposed to be: no one will ever know the difference.

The Imperials did not necessarily venture into photoetch and I'll need to source engine grills for this one. Despite an inevitable negative comparison of Dragon in the 90s to Tamiya (of almost any era) when it comes to simple building pleasure, I would have to say this is going to be a good looking model on the shelf. Assuming I can conquer the individual track links... I've never tried before! I have a few other Imperials in my stash and now know what to expect, and look forward to building more recent Dragon engineering too.

I'll post a full review when this kit is finished. For now, I have some plastic to wrestle with...

Kit Review: Tamiya 1:48 Fw 190 F-8



This kit is 15 years old, #39 in Tamiya's expanding 1:48th scale aircraft range, and while there would be many reviewers quick to point out that the kit is "showing it's age" in ways, I would sooner concentrate on the ways in which this kit is still a very good one, and a very pleasing build. Some might point to Dragon's and Eduard's offerings as being far more detailed, with hatches that display engines and guns, but I would point to the sheer unfriendliness of those kits to build, their susceptibility to misalignment of the major components if key elements of their multitudinous internal fittings are not mounted with exact precision, something many builders only discover retrospectively after doing it wrong the first time.



In contrast, Tamiya offers a basic cockpit and engine, the latter of which is pretty much invisible behind the prop and fan (as is going to be the case with any closed-cowl 190), and the cockpit looks just fine through a closed canopy. Add some harness hardware, that would be about all you'd need to up-detail the cockpit, unless opening the hood.



The cockpit features raised instrument detail which responds very well to drybrushing, and a gunsight which is clearly visible through the windscreen. A choice of standard or Galland Haube (blown) canopies is provided, both crystal clear. The prop mounts on a poly cap, a Tamiya trademark, which allows it to be slipped into place at the very end, easing not only painting and decaling, as the spiralschnauze really needs to be applied to the spinner cone before the prop is built up.

There are some stores options for this, the dedicated ground attack variant of the 190. Twin underwing pallets for R4 unguided rockets are optional vs a quartet of well-molded SC50 bombs and their pylons, while a 300L droptank and rack are provided for the centreline station.



The Tamiya kit builds beautifully. Buildability is a dependable trait for Tamiya and even so early in their series, only a few kits after switching to recessed panel lines as standard, the parts fall together very neatly indeed. The main fuselage and wing parts are super-accurate and align correctly on their pins; the tail surfaces literally snap into place and their tabs and slots are size-coded so you can't get the surfaces on upside down. The engine cowling is a single moulding into which the completed engine sits before the unit fits back onto the fuselage and the gunbay cover drops into place.

A separate insert for the wheelwell brings up the possible detail level, while separate parts for the retraction struts, locking to the legs at fixed pivot pins, assures the main gear will almost fall into correct alignment, a boon when one considers the forward rake and toe-in on the Focke-Wulf undercarriage that can be a challenge on some kits. This is standard engineering that will be found throughout Tamiya's 190 range.



Similarly, the single-piece lower wing surface assures the correct dihedral and a gentle flexed fit for the wing to fuselage joint, often the major issue with joint dressing but here requiring no attention at all. Overall, the joints were dressed with a little adzing and wet sanding over superglue assembly, while some joints were closed with liquid cement on natural panel lines,. Filler was used in only a couple of places, such as behind the engine cowl, down by the wing roots, and to eliminate discontinuities where sprue attachment points fell.

The decals provide for four aircraft, all interesting choices, including the famous Black 10 of 2/SG4 in tropical camouflage for the Italian campaign of 1944, Green Double Chevron of SG2 in March '45, White 7 of I/SG2, in Hungary during the winter of '44 to '45, and Red 2 of I/SG2 in a zebra-pattern winter camo over standard RLM 74/75/76, in early '45. In 1995 Tamiya was recommending mixing rations to reach RLM equivalents from their acrylics range, while later kits offer matches from the Tamiya enamels range.



Their formula for RLM 76 (XF-2 Flat White plus XF-23 Pale Blue plus XF-66 Light Grey ata ratio of 7:1:2, provides a virtually perfect match for the original, lacking only lustre, and an addition of 25 to 30% X-22 Clear Gloss approximates the sheen of the original RLM colours. Unfortunately, their suggested formulas for the 74 and 75 are miles off, and I experimented to find a decent fit. For 74 they recommend XF-24 Dark Grey and XF-27 Schwartzgrun at 3:2, but this was too dark and too green, especially compared to the Model Master enamel equivalent. I reduced the ratio to 3:1 and added 1 part Flat White as well, then brought up the lustre with 30% Clear Gloss. For the 75, Tamiya suggests XF-51 Khaki should be a component, but as 75 has no green hue at all this mystifies me. I mixed it from scratch, starting with XF-24 Dark Grey and adding Flat White at a ratio of 2:1, then adding 30% Clear Gloss. On reflection this was too much gloss, as darker shades reflect more strongly than lighter ones, and 20% would have been ample. The final shades were acceptably similar to the Model Master enamel equivalents, though I have to say the acrylics are both more delicate and lack a certain 'gutsiness' that the solvent-based paints have. I mixed the RLM 04 Yellow also, warming and lightening XF-3 Yellow slightly (it could have gone still lighter...)

The camouflage was soft-masked using light card, while hard edges were acheved with Tamiya tape. This was my first time doing an all-acrylic multi-tone paintjob and I was quite pleased with the result, not pleased enough to say I'll retire enamels, but pleased that I can pursue a build like this in weather which forbids taking the hobby outside to spray solvent-based paints.



If there was any particular shortcoming to the kit, it was the decals. Two sheets are provided, one large, one small, with all the stencil data on the small sheet along with a few squadron markings. The small sheet was glossy and the glue was both slow to release from the backing paper and quick to dissolve thereafter, resulting in decals that were not predisposed to lying down invisibly. Even when gauging the soaking time correctly, some of the decals were prone to wrinkling, calling for considerable skill with solvent and setting solutions to get them to even out and pull into surface detail. I'm very glad I painted the block colour areas of the scheme I chose, as the decal version of those areas I am certain would have been unnecessarily difficult to apply and not looked half as good. There are, of course, aftermarket decal sets for the Fw 190 almost beyond reckoning, many of them probably being released with this very kit in mind, so this is perhaps the least of concerns.

Finishing tricks included carbon staining and dust applied with MiG Productions powder pigments, and an antenna wire made from Berkshire Junction EZLine.



I'm sorry this kit is out of production. Hopefully it will be reissued at some point, and until then one must haunt eBay with a watchful eye to catch it when it changes hands from time to time. My verdict on the Tamiya Fw 190 F-8 is that it is a very pleasant build with few challenges, which can be both tackled by a beginner and enjoyed by a master, and which certainly captures the stance and look of Kurt Tank's masterpiece fighter.

Smart Save on a Dodgy Decal




I was decalling along nicely on my new Focke-Wulf when I had a rare faux pas on one item, the green dash for the port side. I left it to soak too long and the glue, fairly resilient in the first minute or two, pretty much dissolved away so that when the decal was applied, it barely stuck and would rather curl up as it dried out.

What to do? I could paint it, maybe, but I didn't fancy another foray into paint at this stage. I remembered a few saves involving white glue, I did something with a decal many years ago, but I had no white glue to hand. The decal was drying, crisping on the model as I watched, so what did I have close by that would do the job?

I quickly rummaged in my drawers and found Micro Krystal Klear, a PVA derivative meant for attaching canopies without crazing the plastic, or making windows by exploiting the glue's surface tension. The bottle was new, rarely, if ever, opened...

I dipped a fine brush in the stuff and laid in a bead under the up-curled edges of the decal. Then I smoothed it down with the brush rinsed and wetted with water, which squeezed out excess glue and washed it away. Wallah... Couldn't be easier. The decal laid down at once and never moved again, and the glue was invisible against the surface, whatever residue was left.

The moral of this story (besides remembering your decals when they're soaking) is always have a well-stocked supply drawer, and even if it takes years to find a use for a product, rest assured it'll turn up eventually.

Now, on with those decals...

Product Review: Tamiya Masking Tape



I remember building Revell's prototype F-16 when I was a kid, in the early 1970s, the one painted up in red, white and blue. The kit was molded in white so I let the white areas be raw plastic, and masked the hard-edge red and blue. I used cellotape, which over raw plastic had nothing to pull up and gave razor-sharp demarcations. I was very impressed with the edge work, less so with the finish of flat enamels slathered on thickly with a brush, and which somehow managed to migrate under the tape where it crossed detail.

Not long afterward I tackled Monogram's B-52D, painting the whole thing with a brush in Humbrol enamels. The white underside took coat after coat and must have looked like it had been done with a roller... Due to the size I used automotive masking tape and of course discovered the necessity of de-gluing the back. Even over well-cured, thick enamel the tape had a de-surfacing effect that was not attractive. I had planned to mask and paint the walkway stripes over the NMF but after early experiments abandoned the idea. Somehow paint would always migrate under, no matter how well-burnished the tape edge seemed to be...

I used to think joint dressing was the biggest drag in the hobby, but since the advent of both cyanoacrylate glue and better-engineered kits joints have become simply a part of the process, not the disfiguring headache they once were, and the necessity of masking the paintjob has rather moved to the fore as the most time-consuming task in reaching a really good result.

Household/automotive paper tape is not designed for delicate paints and you need to seriously de-glue it to stand a chance. Scotch brand invisible mending tape is not very sticky and produces a very sharp edge. The problem with these two is they are not very flexible, they don't deform easily around corners. In the US there is the blue 'painters' tape,' but I'm not aware of it (or an equivalent) in Australia. To be fair, I've not checked out hardware stores for the item, but there's not much point when you have an item like Tamiya tape in the tool draw.

If there was a perfect product for this application, I'd have to say Tamiya have nailed it. Their tape is low-tack, burnishes down tight, deforms readily, and peels off clean. I have yet to have it pull up sprayed acrylics or enamels over any properly prepared surface (the only time I had it take paint off right through to the plastic was attributable to a deposit left on the surface of the model by the cleaning agent I had used to degrease it). The tape is also essentially re-usable, I have used the same pieces of tape on multiple projects, simply by transferring them to another plastic surface where they can stick for weeks or months and again peel off cleanly.

The tape comes in a variety of widths from narrow to broad so you have the option of curving lines or bulk coverage. I usually put a strip down on my cutting mat and slice it up with a razor knife and steel rule into ultra-narrow pieces or shapes as the job calls for. The dispenser rolls are a good idea, too.

The FW 190 I have on the bench at the moment was masked in both hard and soft contexts. The unit markings featured yellow rudder, cowl and fuselage bands, and rather than go with the kit decals for these items I sprayed them at the same time as the rudder. After overnight curing I masked them with strips of Tamiya tape and carried on with the rest of the paintjob. Several days went by, then I removed the hard masks and discovered perfectly sharp edges, and perfect protection of the underlying paint from later applications.

The big resin Beta-1 bomber featured in the last couple of posts was also fully masked with Tamiya tape, a long and complex operation, but one which went off essentially without a hitch. The colour demarcations are as tight and sharp as you could possibly wish for, with absolutely no paint bleed-under or de-surfacing on removal.

Tamiya tape is an indispensable tool in my kit, and I recommend it without reservation.

Giving Up Enamels: Just Around the Corner?



I've posted a fair few times on the contrasting merits of enamels and acrylics, and despite being a lifetime enamel user I find I'm drifting toward acrylics more and more.

They don't go on as silky-smooth, they dry quicker in the airbrush tip, and for sure you need to get used to them, but the benefits really do weigh heavily in their favour. They're far less toxic, they come in larger bottles that have phenomenal shelf-life, there are enough shades around that you can either get a decent match right off the shelf or mix one without much bother, and they're durable enough to survive gentle handling. Their non-toxic nature means they're probably the only option for indoor spraying if you're health-conscious at all (brain cells, we don't need no stinkin' brain cells!), so you can paint through the winter without being well-enough heeled to have a spray booth/ fume hood in your workshop, and that's the majority of us. Also, enamel paint chemically attacks vinyl so if you fancy anything from anime subjects to dinosaurs via movie tie-in figures, acrylics will be your medium of choice.

They've come a long way in the last twenty years, and modern acrylics are seriously competing with traditional enamels. I've done mostly-acrylic paintjobs on my last eight armour kits, with oil-wash weathering over the top, and it's become my standard armour technique, so it may only have been a matter of time before the medium encroached on aircraft.

The Convair XAB-1 that I reviewed in the box in my last post, rather longer ago than I had imagined (apologies for the long delay in posting!) is now finished and submitted to the commissioning magazine, and it turned out to be an all-acrylic paintjob. I had intended to do the natural metal parts in enamel, but fate took a hand: I discovered I had no enamel thinner in stock other than the dirty thinner in the bottom of an old bottle I use to suspend oils for wash detailing, and as I was on a deadline I realised the metallic would have to be acrylic too. Fortunately I had the shades in hand, so I mixed Tamiya X-11 Chrome Silver with XF-16 Flat Aluminium (9:1) and laid it on in several decent coats. The underside white of the bomber was four coats of satin white mixed from X-2 Gloss White and XF-2 Flat White, while the red of the engine inlets, the chromate green of the wheel wells, satin black of the antiglare panel, dark metallic of the flaps and gunmetal of the exhausts were all previously mixed and sprayed in the same acrylic range.

I was impressed by the covering ability (with the exception of the white, and that's the nature of the beast where white is concerned), and the rapid drying which made multiple coats a practical proposition in a modest timeframe. The job became practical and the finish was entirely acceptable. Yes, the natural metal had a certain grain to it that an enamel job probably would not, and in future I will still work in enamels when the environmental conditions are right; but when they are not and there is a model to be finished, the less-toxic medium is now fully up to the job.

I have a Tamiya Fw 190 F-8 underway with an all-acrylic finish. I'll write a review of this excellent kit when she's done, and talk about mixing the RLM paint shades from the basic Tamiya range, an operation which, at time of writing this article, looks both simple and highly accurate (sometimes...).

Cheers, Mike

In-Box Review: Fantastic Plastic's Retooled “Beta-1”



Resin is an almost ubiquitous medium these days, used by professionals and enthusiasts alike, and often the line between them blurs away to nothing as skills grow and shoestring operations are replaced by full-on limited-production model firms. They're not just 'garage kits' now, they have in fact become a force to be reckoned with.

Fantastic Plastic is one of the success stories of the modern limited-run marketplace, specialising in science fiction, 'realspace' and 'paper' aeroplanes, with high quality kits patterned by master craftsmen and featuring the highest quality resin moulding and casting technology. These kits aren't cheap but they certainly deliver unusual subject matter.

It's not only Moebius and Polar Lights that resurrect classic subjects and recreate lost lines. Fantastic Plastic has had dozens of subjects through its catalogue in the last few years, and they recently released an eagerly awaited kit that brings to life an old 'what if' subject, a mid-Cold War design by the old Hawk company based on theoretical studies by Convair for a nuclear-propulsion bomber, presumably to replace the B-52 sometime around the end of the 1960s. Little could military planners have dreamed in those days that the B-52 would still be in service well into the 21st century.

Nuclear propulsion was a 1950s technological darling, something which worked on paper and was kicked around by 'backroom boys' but never saw the prototyping shop to the best of aviation historians' knowledge. The idea was that nuclear energy created heat which was passed to ingested air to create a ramjet effect without consuming liquid fuel, thus allowing an aircraft to remain in flight for long periods, indeed for as long as crew fatigue parameters would allow, and a whole slew of designs came along from major aircraft firms in the late 1950s.

Kit company Hawk cashed in on the public fascination with this extremely sci-fi concept and designed their “XAB-1,” the B-1 of an earlier era, as the flagship guardian of the West, intended to cruise for long periods on nuclear deterrent patrol, ready to head for targets in Russia if the world ever tipped into DEFCON-1... It's interesting to look back on how this nightmare scenario generated business for lots of people, and the kit industry's perpetual association with militaria is a prime example.



Hawk's original kit was injection moulded at 1:188th scale, and has become a collector's item. Rare unbuilt examples change hands at fabulous prices, a 1964 example is going at auction as I write this, they have become investment properties that one could never afford to build. Fantastic Plastic comes to the rescue with a fully retooled kit in pressure-cast resin, mastered by Scott Lowther and cast by Masterpiece Models, enlarged to 1:144th scale and featuring finely recessed panel lines in the modern style. The kits has a pencil-slim fuselage 17” long, landing gear which may be built deployed or retracted, waterslide decals by Jbot, and features photographic instructions. There is no cockpit detail, no detail in the wheelwells, and a few inconsistencies and flash in the resin to be cleaned up, but these are minor considerations. The original featured red plastic exhaust flames, a juvenile gimmick which has been dropped in this entirely serious 'take' on the subject, while the original's two 'parasite fighters' are also included as superb single-piece resin castings.

The kit comes packaged in a sturdy white card box, whose lid is decorated with a printed colour label featuring digital artwork combing the model with a realistic sky and CGI exhaust efflux, something of a Fantastic Plastic trademark. Inside, the largest castings, such as the one-piece wing and the right and left halves of the fore and aft fuselage sections, are loose in the box, the rest of the 45 parts being collected in a ziplock bag. Many parts are supplied with their pour-stubs already cleaned up.

The hollow-cast parts have alignment pegs and holes, allowing them to be snapped together exactly the same way as injection moulded parts, but curiously some of the pegs and holes don't match up, such as instances of opposing pegs. One needs to do some trimming of pegs and drilling of holes as part of the clean-up phase, but the good news is that the resin, while completely rigid, is soft to cut and works very readily. Go gently and adjustments should take almost no time at all.



There is no clear part for the cockpit canopy, and in so small a scale the model gets away with this. I have long harboured an interest in scratchbuilding this beast in 1:72nd scale, she would be a monster 34” long and 22” in span, and would definitely have a cockpit interior and clear parts. The interesting thing is that the layout of the super-streamlined nose virtually forbids a side-by-side pilot crew configuration, which is widely known (now) to be the only workable one for long duration flight.



I will be building this kit shortly as a review for a major magazine, so look for retrospective comments on Fantastic Plastic's Beta-1 in about a month's time. For now, the kit can be purchased for US$105 from Fantastic Plastic's online store, check it out at:

Fascination With “Type”



Sometimes, without consciously meaning to, we find ourselves on a single-type production line. It can happen for a variety of reasons, and plain fascination with a particular subject matter is probably the single most significant. The hobby is about entertainment, education and general knowledge come decidedly second, so when a hobbyist finds him or herself focussing on a particular subject it's probably because there's an abiding interest.

It might be that you're a fan of MOPAR muscle, and you're on your tenth 1:25th scale Chrysler Corp F-body pro-streeter in a row. Maybe you're an armour fan who belongs to the "panzers only" club because they're colourful. Maybe your thing is vintage biplanes and between them Roden and classic Aurora have occupied your bench time for the last two years.

Of course, it can creep up on you. I recently found myself building four Fw 190 fighters at the same time sort of. One was started four years ago, brought to the painting stage and almost forgotten, back in its box. One was a quick build to work with some AM decals, another was a long-delayed foray into building a leading manufacturer's offering with all the bells and whistles. The last was a chance to work in 1:32nd scale for the first time in twenty years, and only the fourth time ever, on the assumption that there will shortly be somewhere to store and display a model that size.

However it worked out, there are four German WWII fighters on my bench at the same time, which will mostly be in the same RLM 74/75/76 scheme, and that's a plus to production-line building. You can get at least two of them ready for the paintshop at the same time and do both from the same mixing and cleaning cycle, which reduces work and economises on air if you're not using a compressor.

Does it risk boredom? Seeing a long line of the same subject ahead of you can either whet your appetite for completion, as each finished build fuels the next, or dull it completely when some other fascinating body shape and colour scheme comes along to compete with the same-old same-old. I think I'll stagger things, do a 1:72 and the 1:48 together, tackle the 1:32 on its own due to sheer volume, and the last 1:72 separately by default as it has a slightly different scheme. It'll take months to work through them, but I have every expectation that each finished plane will more than inspire me to press on with the next.

I suppose the three Phantoms I have underway also count as a fascination with type. Look for posts in future picking up the theme of the great Hasegawa/Fujimi Phantom Showdown, as both these brands are on the bench and will be reviewed together.

PS: I'm now using Picassa for my image loads, click them and you'll get a larger version from now on.

Recently Completed: Trumpeter SA-2 -- Finishing That Shelf-Sitter



After a long and particularly busy hiatus (involving submission of a PhD thesis, beginning a new job and continuing with past endeavours), I find the itch to resume blogging about my favourite pass-time, and going by the traffic World in Miniature has been generating, fresh posts will probably be most welcome!

In the last few months I've been very busy on the hobby bench, working on a round dozen projects. The trouble with spreading yourself so thin is that no particular project moves along very quickly even though you seem to be working as many hours. The great thing about having some older, unfinished projects is that you can get them off the bench with comparatively minimal work, and that was the case with Trumpeter's SA-2 Guideline missile kit.



I began this item probably two years ago, and did almost all the construction at the time. I was very happy with the fit, the cylindrical missile parts lined up very nicely and joints were dressed with the old superglue and adzing technique, always the best and quickest way. The alignment of the sixteen fins were more problematical, a right-angle jig would be a great help, as I doubt I got any of them at exactly 90 degrees. Still, 89 is close enough to satisfy the eye from most angles.

The thing that stopped me at the time was “Russian Green.” What shade is it? I have an old tin of Humbrol Russian Armour Green, which is no longer in the range, and I'm hoarding it. Besides, these days I try to paint in acrylics whenever I can, especially for armour subjects as it's not only far less toxic (and fairer to the family where the stink is concerned), it also lends itself perfectly to oil wash weathering afterward.



I did some research online, found my way to chat boards and such, and found that there were actually several shades of camouflage green in simultaneous use in the Soviet military, and any of them would be used in any particular context on the basis of what supplies were available. One common shade has been calculated to a Federal Standard value of 34098, and given that 34097 is a standard US shade, available in model paint ranges, I decided this was close enough for me. Tamiya XF-58 matches FS 34097, so that became my launcher shade.

Still, that alone was not enough to get me to pull the box off the shelf and get to it. As I'm sure I've mentioned in some previous post, I use a commercial compressed gas cylinder to power my airbrush, and I recently had a negative experience: for the first time in 15 years, I had a defective cylinder. I picked it up and seemingly overnight the fill had dropped from 15 bars to 10. I thought I had maybe failed to safety the main tap correctly, and heaved a sigh of frustration, but the next time I came to it the reading was 8, and I knew I'd safetied it properly that time. I talked to the company and they agreed to exchange it (they checked it and my gauges and the tank was definitely leaking). There was a weekend in the way, however, so I did some spraying and tried to use up whatever air I had available. The SA-2 was one of the kits that got some long-overdue attention.



I sprayed the launcher's six subassemblies with a good coat of XF-58, then I could do the standard armour weathering techniques I've developed. The big idea with this kit is that the launcher and missile are, literally, two different kits. In Soviet markings the installation is typical of the air defence settup found in North Vietnam, and this offers interesting finishing possibilities. The launcher stood in the tropical heat, dust and rain of Vietnam for years, and despite maintenance it would suffer the extremes of climate. Naturally, it would display rust and dust, and general dirt, just like any piece of heavy equipment. The missile, however, would not, being transported to the launcher site, loaded and fired long before weathering could set in. Also, the missiles themselves probably received more protection from the elements than the launchers.

So, I pursued them as separate projects. The missile was a painting experiment also. The pale grey shade used on the missiles seems to have no Western equivalent, so I mixed it. It was not the flat camo of the launcher, but either gloss or semigloss. I've had problems spraying gloss, and was not convinced the missiles were full gloss anyway, so I mixed 50% X-2 Gloss White with 30% XF-2 Flat White and 20% XF-66 Flat Light Grey. On reflection the finish is not quite bright enough and the shade not quite light enough, next time I build one I'll raise the gloss white to 60% and drop the grey to 10%, which should be a better mix. Nevertheless, I'm happy with this one, the grey certainly looks pale against the launcher green. Weathering was kept to a minimum, a thin black oil pinwash around raised details and recessed panel lines simply to make the structures visually 'pop.'



The missile is covered with stencil decals, more than forty of them. Many of them group adjacent Russian data placards, and they can be fiddly: I mangled only one decal in the process, and decided for ease to separate out elements from one or two others, which both extended the time involved and simplified getting a correct positioning. I was still decalling as I wrote the first draft of this post.

Speaking of decals, Trumpeter's printer, Cartograf, in Italy, have done a remarkable job on them. I don't think I have ever seen kit decals snug down into the surface so tight, and with carrier film that literally vanished against the lustre of my paint mix. The dried decal transparent areas are faintly lighter than the background, that's the only thing that gives them away. Placement instructions could have been more explicit, though. There is one interesting gaff, one of the red stripe markings that circles the body, just back of the juncture to the nose, is incorrect. Under a magnifying glass you can see that, instead of Russian stencil data, it says in English “NO PHOTO SORRY” – presumably a notation from the research team during creation of the decal sheet which, as it was not in Chinese, accidentally made its way through quality checking all the way to manufacture. Having omitted this one, I used a few bits of stripping from it to help repair the mid-body wrap-around decal that I mangled somewhat.



Final details involved spraying a grey-black mix to simulate the scorching of the rocket efflux on the blast deflector, brush-painting inside the rocket motor with a dark metallic enamel, fitting a few tiny parts on the launcher, including a few that fell/broke off during handling, then I could get some MiG “Vietnam Earth” pigment onto the launcher. This is good stuff! I can't wait to apply it to some Vietnam-era US armour.

Mating the two stages was an interesting job. A snug fit to start with, the paint on the alignment runners made it extra-snug, so I worked the boost stage carefully onto its guide, then slipped the upper stage onto its own guide and glued them together actually on the ramp.



It's the only kit I've built in many years which uses every last part and decal: there are no alternatives provided. However, three small decals, 8, 9 and 15, don't appear in the instructions: 8 and 9 are the starboard side counterparts of 7 and 10 and go at the base of the small aft fins on the second stage. 15 I haven't spotted anywhere.

All in all, this was a very pleasing model that built well and looks sharp on the shelf. I'm not sure if it's still in production but examples change hands on eBay for reasonably attractive prices these days. As a companion to Revell's re-released Nike Hercules missile, a similar vintage and role of weapon, and in fairly close scales too, it makes a most interesting display of Cold War technology.

PS: Yes, a part fell off the launcher and was not reattached before I did the photos, a sharp eye will spot the absence in the photos above. So, sue me...

A Thousand Appologies...

... for the month that's gone by since I last posted. I honestly expected to see a post about my recent experiences working with ProCast resin at a lab at my local university, and was amazed to discover that with all the flap in the last couple of weeks over getting my PhD thesis completed and submitted that I hadn't actually uploaded the darn thing. I wrote it, I took the photos, but...

Normal service will be resumed as soon as possible! And there's plenty happening on the modeling bench for the foreseeable future!

Cheers, TB379
