Object 279 (1/72 OKB Grigorov)

ama2wkw

I have written a review of this kit for Armorama; most of the introduction is reused for this post.

There are three 1/35 kits available for this tank, all of which were issued in recent years -so officially there are more models than actual vehicles in existence. (Something only the Tiger I has achieved to this day.*) Before the styrene versions came out almost at the same time (which makes me wonder how companies decide on what to work on next and why they always seem to decide on the same vehicle**), there was a 1/72 resin version by OKB of this extraordinary-looking tank. Frankly, it looks like the tracks were only an afterthought; you’d expect to find anti-gravity propulsion installed. (Perhaps the subcontractors were late with that project.)

*~ducks~

**these days we can all anticipate the incoming new King Tiger kits with full interiors… it’s an interesting choice to flood the market with something that someone already is producing instead of coming out with something new. This enigma, along with the tendency of Hollywood to do the same thing with movies, will always perplex me.

The tank was designed in the Kirov Plant in 1957 to resist HEAT ammunition and have good off-road capabilities (the ground pressure was less than 0.6 kg/cm2). The weird shape would also ensure that the maintenance would be a nightmare for the crew -especially if the tank threw a track. Surprisingly it was able to reach 55km/h, and had a range of 300km, which is pretty good for a heavy tank-  even more so for one with four sets of tracks. (Decreased air resistance due to the shape of the hull might have something to do with this…)

The shape of this tank was due to a second layer of shielding which covered the hull. It served multiple purposes. First of all it was supposed to make it harder to flip the tank over (nuclear blasts do tend to have some strong shockwaves). It also worked as a protection against HEAT and APDS projectiles, and against shaped charges. (I really would like to crawl into the prototype displayed in Kubnika to see what the interior looks like.) The tank was obviously equipped with CBRN protection. The main armament was a rifled, 130mm gun (M-65) with 24 rounds of ammunition, the secondary armament was a KPVT coaxial machine gun; they were stabilized in two planes.

The history of the tank was not very illustrious. Once the prototype completed all its trials (which showed a couple of problems with the track system), the program was axed by Khrushchev himself, as it was way too heavy for the requirements set for new tanks. (In short, the Soviet leadership viewed heavy tanks as outdated, and were obviously blind to the propaganda value of a weapon created apparently using alien technology.)

It took me some serious deliberation to purchase the Braille scale version of this model by OKB as it costs about the same (or more in some cases) as the 1/35 versions. In the end I’ve decided to go with it as I prefer this scale in case for large vehicles. I have a constant space shortage at home, which is the main reason my 1/144 Dora stays in her box for now.

Interestingly as I was progressing with the build, Wargaming just came out with a video on the tank itself.

The model comes in a small, sturdy cardboard box. The box art is a photo of the vehicle displayed at Kubnika; however it was seriously faded in my kit. In it we find several small Ziploc bags, and some pieces of bubble wrap which make sure that the kit arrives unharmed and undamaged.
The instructions –which are a rare thing indeed in resin model circles- are clear and computer generated. The only problem is that it’s difficult to see the images as they were pretty faded. (OKB will email you a set of instructions if you ask them ASAP, so this is not an issue.) Since the model is relatively simple, even using the faded instructions does not impact on the assembly process.

The model is made up by about 70 resin pieces and 30 PE parts. The parts are very well detailed, the flash is minimal, and the fit is excellent. One of the swing arms of the suspension was miscast, but generally the quality of resin is excellent.

The tracks are given as sets of straight resin pieces, which need to be warmed up before being shaped to fit the running gear. (I prefer hot –not too hot- water to a hair dryer for this job. Hairdryers can be surprisingly hot, and damage the resin.) The hull comes in one piece; most of the small parts make up the running gear. The muzzle break on the gun is something to be seen: it’s quite a complex shape with several openings and it’s moulded in one piece; A pretty impressive affair. The photoetched fret is very thin and very delicate; it’s very easy to bend (even crumple) the parts, which makes working with them a bit difficult.

Putting the running gear together was not very difficult; the swing arms fit into their slots remarkably well. (The small wobbling unfortunately will show when you attach the wheels, as they will be somewhat misaligned. When the suspension units are done, it’s best to use some hot water to warm the whole thing up, align everything between two rulers, and wait for the resin to cool down.

I would have preferred to put the tracks on while the assembly was off the hull but the drive wheels are separate units. This means you’ll need to glue both the running gear and the drive wheels onto the bottom of the hull first, then add the tracks. To make your life easier you can add the front section of the tracks on the suspension while they are off the hull.

Now, there was a little issue at this point: one of the sections holding the running gear did not fit into the groove on the lower hull. After a little fiddling I found the reason: it was a couple of millimeters longer than the other. Some trimming had to be done to make it fit. Another issue I’ve already mentioned: one of the suspension arms had a casting error, so it was too short to add a wheel. I made sure this section was turned inwards so it would not be seen.

The face of the drive wheels is made out of PE. As I said the PE bends very easily, so assembly was not exactly easy. (They bend readily even to the small pressure needed to push them in place.) Since the resin axles were a bit thicker than the holes in the PE parts I needed to trim them a bit using a knife. I used epoxy glue for most of these parts, since I wanted to make sure they will hold strong; this is important especially when you install the tracks.

Once the drive wheels and the whole running gear was on the tank, I added the tracks. (Warm them up, wrap them around the running gear, wait.) There are some tight fits between the running gear and the bottom of the hull, but all four sections went on eventually.

The hull is not a difficult affair to assemble: you need to add the towing hooks, the PE tiedowns for the external fuel tanks on the back, and the PE handholds. These handholds were a bit problematic: you need to fold the legs down, but there is no marking where to fold; these markings usually make it easier to fold the part in a neat right angle. Use a plyer or a hold-and-fold. The metal is very thin, so it is extremely easy to distort its shape while working with it.

The travel lock is made out of PE (not sure if you can make it functional; the gun barrel is made out of several pieces, so technically it should be possible.) The headlights and the guards for the headlights are pretty easy to install. I noticed that the metal strips for the guards are somewhat longer than necessary, so I trimmed them, and made a little fold at the ends so they stick better to the hull. The exhaust has a rectangular metallic guard around it.

The gun barrel made out of several sections, and it’s kind of hard to make all the pieces align perfectly straight. The muzzle break, as I said, looks really great.

The turret is also a simple affair There are two PE squares on the top (I think this is where they are supposed to be- it was hard to see on the instructions and the photos were not very good for that angle). The IR headlight is fixed next to the gun, I’ve prepared a couple of handholds using wire, and attached the gun barrel; that’s it. (Obviously I only primed the tank so far; it will be finished after the Christmas holiday.)

Once I had the rust-brown base coat on, I’ve sprayed some Tamiya Nato green lightened with tan, and mixed with some AK Washable agent as a test. The test was a partial success – some vigorous brushing did manage to remove some of the paint. Clearly more experiments are needed with different paint/agent ratio. Once the paint was dry I fixed everything with some varnish and added some decals from the leftovers. The decals were fixed with some Dullcote.

 

 

 

I proceeded to add oil washes, and some light ochre filters, and went on to see how I can make the tank look dirtied up without overdoing the effect.

I picked up some Tamiya weathering sticks in HobbyCraft at their latest sale, so that was the first stop. It’s a strange, almost lipstick like product (pen shaped), and direct application only deposits some non-realistic smears. Using a stiff brush to add the paste and adjusting the pattern after application with a wet brush seemed to work well, though. I used the mud version to add mud on the lower chassis and the running gear, along with the edges of the top of the tank; and I used dust to add deposited dust/dry mud onto the top. With downwards stokes I tried create a perpendicular pattern to the edges as if they were marks made by the water pouring/tickling down from the hull. I repeated the process on the turret as well although much more subtly.

Since it did not look enough (only two colors do not look very convincing) I’ve mixed up some darkish (almost black) brown mixture of pigments and matte varnish, and flicked it onto the hull with a brush and toothpick to simulate fresh mud splashes.

I’ve used some weathering effects (oil stains and diesel stains) on the running gear and the external fuel tanks, respectively), and called the tank finished.
The build was not a challenging one; in fact it was easier to build than most resin models I’ve built so far. This is the third OKB model I’ve built, and I have to say they are very well engineered models: clear instructions, good detail, and no major issues to remedy. The only real drawback is the price- for most people this would make the 1/35 offerings more attractive.

 

Mirage Hobby (72627) 76,2mm “Leningrad” SPG

wrffbxi

Ever since I started to play World of Tanks I have been partial to the SU-26. It is tiny little Russian SPG in the game with considerable fame (until they nerfed it). It had a fully rotating tower, it looked funky, and it had an amazing rate of fire- what’s not to like? Since I liked the in-game vehicle, I was trying to find it in scale model form. The SPG itself is quite unknown (only 14 were built on the basis of the T-26 light tank), but I was delighted to find something similar in polystyrene…

su-26_1680_1050

Enter Mirage Hobby.

mrg72627-300x155

The SPG looks somewhat similar to the beloved SU-26, although the gun shield is most definitely not the same. I debated if I should build it out of the box, or modify the kit to resemble the SU-26, but the forces of caution won- I did not modify the kit.

The model went together without any problems; no major fit issues. The detail is reasonably good -better what I expected, in fact. The tracks are rubber band style, and the suspension is surprisingly good for this scale.

The painting was done with brush only. I used Citadel paints, since back then I was living in a tiny room surrounded by all my possessions in boxes. The mud and dust was applied using the good old drybrushing technique and the different earth shades offered by Citadel. (I was writing up my thesis, and rented a very small room to save on money. This meant most of my modelling equipment, paints and pigments were packed away.)

This is the finished product in a display case:

I’m seriously thinking about ordering another kit to do the necessary changes for an SU-26.

Bergetigers

I’ve built two of DML’s Bergetigers. The first one is based on the Tiger I (P) chassis, and was a legitimate “berge” vehicle: it was modified for battlefield engineers for recovery and other tasks where you can’t work in peace and quiet without someone taking shots at you. It’s a pretty good model with PE and high level of detail; the build was quite enjoyable.

In this model I’ve used silly putty to prepare the net-like camouflage I liked from the painting guide. As a green base I used Tamiya’s German grey – with scale effect and subsequent weathering considered it gives a quite nice olivegrun base.

Adding the silly putty… it’s quite relaxing and surprisingly fast.

Yeah, I forgot to say. We’ve got a link-and-length track here, which is surprisingly easy to assemble. (As opposed to some models I could name.)

Once the camo was done I could dirty up the lower chassis, and finish the running gear. This was followed by some some light weathering (mostly washes and filters; I did not go overboard).

Bergetiger I -second vehicle.

This Tiger is somewhat of a mystery. It appears to be a field-conversion, and only two were ever produced (or perhaps only one). The crane fixed to the turret is definitely not strong enough to actually lift a vehicle out of anywhere (any vehicle; I’m not talking about Tigers -it would be difficult to get a Beetle out of a driveway with it), and it’s also hand operated. From the outside. Not a very healthy place to be if you need to modify a tank to be able to do whatever you want to do with it.

The most convincing explanation I’ve found was that this vehicle was used to drop demolition charges in front of barricades and minefields; however, it still does not explain why the crane operator had to stand outside of the vehicle.

Anyhow, it has an unique look, so I was very eager to build one. You can get several conversion kits in both 1/35 and 1/72, and there are some dedicated kits as well you can occasionally fetch up on Ebay. DML did come out with their own version years ago. The model is sub-par when it comes to other Dragon models. Looking at the sprues it’s quite obvious that the different parts were scavenged from different Tiger models, which make the quality wildly diverse (this is an issue with some other DML Tigers as well).
So it’s not a good model. Even though it’s not up to the expected DML standards, but it’s not a bad model, either; it’s just a bit disappointing to get something like this from Dragon. The bottom of the hull is metal, by the way; it must be one of the really, really early 1/72 kits by DML. (Or perhaps they wanted to have a realistic weight; who knows?)

Turret with the crane… I’ve used some copper wire for the cables.

I’ve had some fun with the mudguards, to make them a bit more varied: I’ve cut up the long piece into sections, and attached them slightly disjointed, with some sections left out -after all, this is supposed to be an already battered vehicle that was converted into a different role.

The tank is painted in Dunkelgelb -no special camo added.

The Tiger has pre-moulded Zimmerit added; it’s a bit too accentuated for this scale, but hey; at least I did not have to do it myself. After covering the model with Future, some light washes with burned umber (the most used oil paint color in model building) helped to bring out the details.

And the finished tank… It does not look bad, once done. And it’s mighty heavy due to the metal parts.

1/35 Trumpeter 1K17 Szhatie Part 1.

028

The term "laser tank" evoke images of alien skies, gigantic space ships, Astrates, and the rest of the delightful Warhammer 40k universe.
In other words: this guy.

The 1K17 tank will not melt metal and evaporate hordes of heretics and Titans; however it does have a gigantic set of solid-state lasers mounted on a tank chassis. These were intended to blind the optics of missiles, airplanes, and other enemy weapon systems. I have not been able to find analyses of this laser-weapon’s efficiency, as the production of these vehicles was hindered by some serious practical issues. One of them is right in front of you: the optical elements of these lasers were made out of 30kg artificial rubies – each. This obviously increased the production costs somewhat, which essentially made sure that these vehicles were not built in sufficient numbers.
 The project was based on the MSTA self-propelled artillery. They kept the hull, and changed the turret so it could accommodate the solid-state lasers. The hull itself is based on the T-80, but the engine installed is a 840hp diesel engine from the T-72.

As it was already mentioned, the costs themselves were enough to doom this project; the two vehicles built were mothballed. They still can be useful, however; after all, they are perfect if you need a gigantic laser pointer to distract some invading mutant tiger army.

The plastic is good quality, and easy to work with. The detail is crisp, and very fine. Some of the parts will need to be handled with care, as they are really thin. The wire guards for the headlights look especially fine. The PE fret included has the mesh covering the engine cooling hatches, and some extra small parts that could not be produced using plastic, like the clamps for the storage boxes. The transparent sprue contains the vision blocks, and a part for the remote controlled AA machine gun. The way some of the periscopes are attached to the clear sprue is also a bit problematic: one side has almost no space for the cutter between the part and the sprue’s frame. 

The decal sheet includes a LOT of numbers so you can customize your tank (not that you have many options if you want to be historically accurate), and a set of Soviet-era crest.

Since this kit is built on the Trumpeter MSTA kit, you get a lot of extra parts –the gigantic gun included.

The build was really straightforward and relatively quick; I have not run into any difficulties. The assembly starts with the hull, as usual. Right in the beginning, there are some issues with the instructions. In the first page it is indicated that you should not glue the towing hooks; I believe the symbol should be next to one end of the unditching log’s holding straps. (This realization was a bit late for my build.)

The headlights are somewhat difficult to glue, and mostly because of the engineering of the kit. On the real tank they are attached directly to the metal guards (which are essentially metal frames) using one little peg. Unfortunately the model headlights are constructed the same way. You’ll have to attach the headlights with this peg, and position them perfectly while doing so. This is a tricky proposition, and some other solution that would have helped with the positioning while drying would have been nice. (I used silly putty to position the lights, and superglue to fix them onto the frame –see photos. This method worked surprisingly well.)

The fenders, the storage boxes and the side-skirts are assembled as separate units. All the clips for the storage boxes are provided as PE parts; it takes a while to attach each and every one. (I can imagine how practical this setup is in real life… “hurry, get the tools!” “Yes, comrade, give me half an hour to undo these straps!”.) While I was taking the photos, I realized one clip was left out on a box– which was attached after the photo session. (This demonstrates why it’s worth taking photos of your models while building them.) The greatest issue with how the kit is designed are the side-skirts. The side-skirts of Russian tanks are usually thick rubber painted over with the camouflage colors. If you look at photos of T-70s, T-80s, etc, you’ll see that the side-skirts are readily deforming, they separate from each other, and they are obviously not rigid. Unfortunately Trumpeter did not give any impression of the flexible nature of the rubber: they are rod-straight. They could be made out of thick metal for all we know. (I say “unfortunately”, because it’s not an impossible task: Revell has managed to capture these rubber side-skirts amazingly well in 1/72 scale.) There’s also no obvious method of leaving them off. If you choose to display the tank without the side-skirts (as the 1K17 is displayed in the reference photos available online), you’ll have to saw them off. (And thus display the incorrect suspension…) It’s such a simple thing to do, which, nevertheless, would dramatically improve the look of the tank. The rest of the vehicle has been so meticulously reproduced; I have no idea why Trumpeter got lazy on this issue.

057055021050

Before the fenders are attached you will have to assemble, paint and weather the running gear, tracks and most of the hull. Once the side-skirts are in place, you will not be able to get to those areas. The turret is well done; some of the panels do not fit perfectly, so filler will need to be used. (The welding lines are very nice touch on the edges of the armor plates.) There is some crucial missing detail here, however. Looking at photos you can see that the lenses are protected by lens protector flaps (which are provided), but there is also a rubber band around each lens assembly that enables these flaps to close weathertight.

These rubber bands are missing, which is a shame. The instructions also fail to give you options for leaving the middle lens covers in an open or closed position. Again; photos are available, and can be used as reference, but the instructions should highlight the options available nevertheless.

 

 

043042

The lasers are housed in a separate box, which is attached to the turret. Before closing it in, I’ve painted the back of the transparent lenses red (Ruby red from the Citadel paint range), and the inside of the box was painted black. There’s an awful lot of free space inside the turret, so someone with a little patience and a small LED light can actually make a pretty cool modification lighting up the lenses -although it would not be a set of coherent light beams, of course. (I might just do that, actually.)

041040039

The fit of the assembly containing the laser with the turret is not perfect; it forces the sides of the turret apart visibly at the attachment points. (This can be remedied if you cut the holding pegs, and glue the part into place.) You’ll find the opposite is the problem with the long, protecting strip on top of the laser-weapon: it is supposed to be movable, but it just does not click into place easily. The attachment between the parts is flimsy, and it falls off quite easily; you would be better off gluing them fixed.

 

038037036

One serious technical gripe I have with the kit is the tracks. The guide teeth will need to be glued onto each and every track link. To compound this issue, the teeth are attached to the sprue right where the track link and the guide teeth are joined; this means you will have to clean up each and every one of the 174 or so guide teeth with a scalpel before you can assemble the tracks. This is when you wonder why they could not mould these parts together, or even better yet, use a link-and-length solution.

030029

Dryfitting… the model is taking shape nicely.

028

The turret, interestingly, “sits” on the hull; the usual pins, that are making sure the turret stays in place, are missing. I’m not sure why this is the case. Most of the time it should not be a problem, as the fit is quite snug, but this could be an issue during the transport of the model. (Alternatively you can just glue it in place.)

 

026

More dryfitting…

023019

016

The AA heavy machine gun turret is a subassembly on its own right; it is a very nice representation of the real thing. After this we’ll just have to glue the millions of grab handles in place, and the model is essentially done.v

Well, that’s it for building. Next part -painting

 

 

 

30th Post: a Teaser – Flyhawk Panzer II.J., Panzer I. F., Armory MS-1 (T-18) and the Tankom 1/144 Landkreuzer Ratte

This is the 30th post of this blog, and since I’d like to have regular readers, feedback, comments, and all that jazz, it is also an unashamed attempt for getting people to visit… There are several new and old builds waiting to be published in the draft section, but here are four amazing models I am reviewing for Armorama this month… and these three will also be featured in this blog. So… subscribe and keep coming back here already!

(If this does not work, I’ll be posting the third page from The Sun from now on.)
