Miniart 1:35 Scale Kit #35136
Review by Terry Ashley

Miniart
Introduction:
The GAZ (for Gorkovsky Avtomobilny Zavod) AAA triple axle truck was a development of the earlier double axle GAZ-AA which was a licenced produced copy of the Ford Model AA 1.5ton truck. The GAZ-AAA was a simple triple axle  6 x 4  truck that proved to be robust and reliable and apart from the basic cargo truck also formed the basis for numerous variants such as an ambulance, mobile workshop and also a platform for  AA guns. The GAZ-AAA was produced from 1934 to 1943 with modified versions appearing in 1940 with the two spare wheels moved to the front fenders (as in this kit) and again in 1943 with flat sheet metal fenders (Miniart kit #35133 to come) and was also used as a base for the Ba6 and Ba10 armoured cars.

The kit:
Following on from the initial 1937 production GAZ-AAA truck kit #35127, Miniart have now released this kit of the Mod.1940 GAZ-AAA truck that is basically the same as the first kit with the addition of the front fenders having the recesses for the spare wheels that were moved from under the rear cargo tray on the Mod.1937 truck, this basically being the difference between the two models externally. As a consequence this review will also be the same as for the first kit with just the comments regarding the new fenders and spare wheel location and the different making options and figures in this kit.

The kit consists of:
398 parts in light grey plastic
7 clear plastic parts
42 etched brass parts
15 additional figure parts
16 page instruction booklet

The quality of mouldings is very good overall with few if any visible pin marks and just a minimum of flash although the smaller parts on the two Fb sprues have considerably more flash than the rest of the parts and needs a lot more clean-up. The main clean-up is with the usual mould seam lines and those on the small and thin parts need care while removing, also the sprue attachments on some parts needs care removing to avoid damage to the parts. A few of the small parts were actually broken on the sprues and needed repairing before use. Oddly the same parts were broken in the same places in all three kits I have which would indicate some stress on the parts, but they were easily glued back together so it was only a minor hiccup.

Dimensionally the kit measures out well against available plans and data in the Tangograd and Tank Power books listed below with the details matching period photos and data very well indeed although the number of parts doesn’t make for straightforward assembly in some areas, most notably with the suspension where there are some traps for the unwary. With the build below I have only assembled the main structures to test the fit etc. with all the smaller items such as headlights, bumpers, door handles, wipers and the hood and rear tray latches plus the etched parts still to be added, I also assembled some sub-assemblies differently than indicated in the instructions as I found a couple of areas where there is potential for problems if not careful. It is of course up to the individual if they want to follow this or build as per instructions, the variations are just suggestions.

Chassis/Suspension:
The chassis is made up of multiple parts with the main chassis beams correctly depicted as U beam with the correct wood (in plastic) rear tray mounting beams, these are joined together with separate fine U bolts. It’s best to glue the brackets (parts Fb19) firmly to the chassis before fitting the U bolts as this makes the process a lot easier.

The two chassis frames join together with several cross members and you must ensure the front cross member (part A83) is set perfectly at right angles to the chassis frames as this has a direct bearing on the location of the radiator which in turn the fit of the engine hoods, more on this below. You also need to ensure the chassis assembly is perfectly square and level before the glue dries as everything else in the kit fits to the chassis and this must be done correctly to avoid follow on issues.

Assembling the rear differentials/suspension is a little tricky due to the many separate parts, you should firstly glue (and let dry) the spring supports (parts Fb24, Fb25) to the respective axles (parts Fb11, Fb12) taking careful note of the orientation of the axles. When fitting the axles to the central differentials you must ensure the spring supports are positioned perfectly vertical to the top of the differential, any slight variation off the vertical will affect the fit of the spring units later.

The double leaf spring units are best assembled and glue allowed to dry prior to fitting to the axles as this will make things easier during final assembly of the suspension. Also note the exploded assembly instructions showing the fitting of the leaf springs to the axles has the leaf springs all upside down and transposed and will confuse things completely if not careful? Firstly they have transposed the sub-assemblies 9 and 10 (10 should be at the top and 9 at the bottom of the illustration in step 13) and the mounting brackets (parts Fb22) are shown on the inner curve of the axle 10 when it should be on the outer of the spring curve as in the other illustrations.
If this sounds even more confusing it’s best to refer to the fully assembled illustration on the left of page 4 for the correct appearance of the assembled suspension. Also the bracket on leaf spring 10 is numbered Fb2 but in fact should be Fb3, Fb2 being the bracket for leaf spring assembly 9.

When assembling the differentials I firstly glued the joining drive shaft (part Bb5) and let the glue dry as this will set the diffs at the right spacing and ensures the differentials are aligned correctly before you fit the spring units. The drive shaft will have to be cut away again to fit to the chassis but more on that below.

When fitting the differentials and leaf spring units together the ends of the springs may not align precisely with the locating pins on the spring supports if these were not set perfectly vertical during the earlier assembly as mentioned above. But the important thing is for the spacing of the axle stubs to be equal both sides and the correct alignment of the axle stubs horizontally not so much that the springs sit precisely in position within the brackets, if that all makes sense? Also let the glue dry on this sub-assembly before fitting the unit to the chassis frames.

Assembed suspension unit as above ensuring the axles are evenly spaced (1)
and perfectly level (2), also the central differentials/driveshaft should also be level (3).

Once the glue has dried on the suspension sub-assembly and you have ensured everything is aligned correctly the drive shaft (part Bb5) will have to be temporarily cut-away to allow the assembly to fit over the chassis cross members and then re-attached. This may seem a bit odd in not fitting as per the instructions but I found making sure the alignment of the axles was perfect before fitting to the chassis aided the wheels to sit evenly after fitting, the springs will flex out enough to fit over the chassis locating lugs without any problems.

Once the differential/suspension unit is attached to the chassis and left free to pivot the drive shaft (part Bb5) was re-attached but the shock absorbers (parts Fb16) and forward drive shaft (part Bb1) were left off until the front wheels were fitted later to ensure all six wheels sit evenly on the ground.

The front suspension is quite straightforward but there are some small parts that need care during assembly, the attachment points for the diagonal leaf springs are very delicate and will break if too much pressure is put on the suspension after assembly so take care. There are additional steering rods added between the suspension and chassis but the wheels are not designed to be steerable, you can position them at an angle to animate the front wheels but they are fixed in whatever position you choose. The assembled front suspension is then attached to the chassis cross member (part A83) and this should be left to dry completely before fitting the brake drums of wheels to ensure it stays where it should.

There are numerous other smaller parts added to the chassis such as the fender supports, rear tail light assembly with etched parts for added detail as well as the front bumpers and rear tow hitch. Overall the chassis and suspension parts fit well but there is potential for problems if not careful with the rear suspension alignment and the position of the radiator as indicated above.

Engine:
The GAZ 4-cylinder 3285cc engine (or 1930 Ford Model AA from which it derived) is another multipart assembly and produces an excellent representation of the engine with all the major features accurately done, these include the separate head with spark plugs with excellent definition, separate intake and exhaust manifolds, generator, alternator, front fan and belts and the rear gearbox and the lower oil sump. It really only needs the wiring added to produce a standout engine and the front support (part A35) is located on the chassis cross member (part A83) when this is glued in place later as mentioned.

The radiator is made up of two main parts with a separate top filler cap as well as a small etched name badge on the front. The detail on the radiator mesh is quite subtle and assembly straightforward but you shouldn’t glue the radiator to the chassis cross member (part A83) at this stage. This is because as mentioned above the position of the radiator dictates the proper fit of the four separate engine hood sections so you should leave the radiator off until after fitting the cab and then use the hood parts as guides to get the radiator in the perfect position as any small miss-alignment of the radiator will see the hood doors not fit correctly.

Wheels:
The wheels and rims are the correct sizes and the tyres are split into seven thin sections that sandwich together to form the full wheel with excellent tread detail, just make sure you fit the tyre slices in the right order and around the right way to get the desired effect. It is advisable to use a soft pen and number the tyre slices as you remove them from the sprues to avoid confusion as there is a total of 56 slices for the six truck wheels and two spares.

Assembly is straightforward really with parts C1 to C3 joined in one sub-assembly and C4 to C7 in another sub-assembly, the first sub-assembly (C1 to C3) is then added to the front of the wheel rim and sub-assembly (C4 to C7) to the rear of the rim, note the locating holes will only fit one way, so don’t force it, if the fit is not precise just turn the tyre section around till it does.

Take note of the different rims for the front and two duel rear wheels during assembly, once the wheels are assembled the two rear wheel rims can be joined to form the duel wheel arrangement. The tread pattern has excellent definition but a light sanding with wet-dry will ensure the tread is nice and even without any lumps or bumps. The brake drums and wheels can be added to the axles and then with all six wheels sitting evenly on the floor the remaining rear suspension shock absorbers and linkages can be glued in place to keep everything aligned.

1-3 assembly added to outside of wheel rim disc then 4-7 assembly added to rear of wheel disc.
Note the small lugs and holes only align one way so don't force the sections together, just turn the tyre section around
till it fits neatly into place, this will ensure the proper tread pattern alignment.

New Fenders:
As mentioned the kit has the revised front fenders with the recesses for the spare wheels and have the same underside ribs to be added and have the underside indentations that match to the chassis ensuring they are positioned correctly but again due care is needed for the best fit. A five part mounting bracket is included for the spare wheels and this assembled and attached to the rear of the wheel, this is easier than fitting to the cab side as there are no locating points to get the right placement to the wheel when fitted.

Unfortunately there is a fit issue with the spare wheel into the fender recess where the recesses are not wide enough for the wheels to sit into the recess correctly and you will need to widen the centre section of each recess. Some careful knife work is needed due to the fender and recess contours and I used a curved #10 blade to carefully trim away the required amount of plastic and test fitting the wheel along the way will determine the amount of trimming needed.

Fender recesses are not wide enough for the spare wheel to fit properly
and will need to be widened for the spare to sit into the recess correctly.

With the recess widened the spare will sit properly as intended.

Once these modifications have been done to the recesses the spare wheels can then be added with the rear mounting bracket positioned against the cab wall.

Cab/Engine Hoods:
The instructions show to fit the cab floor to the chassis and then build the cab up around this but I found it easier to assemble the cab as a complete separate sub-assembly and then fit this to the chassis later, but again this is up the modeller to determine.

Extreme care is needed when gluing the upper cowling (part A97) to the inner instrument panel (part A38) and in turn the windscreen frame (part A101) plus the two side body panels (parts A39, A40) as there is potential for miss-alignment and unsightly gaps at the sides if not careful assembling these parts. It also helps to add the firewall (part A66) at the same time to ensure the side body panels are correctly positioned, but with due care the fit is good.

Once this assembly has dried the clear windscreen with additional etched parts for the side brackets and windscreen wiper can be added, note the windscreen can be fitted closed or open and the side etched brackets fitted accordingly. There are also additional detail items added to the firewall as well as the inside driver’s foot pedals and gear levers as well as the seat cushions on the floor frame and rear wall. The separate instrument cluster has a very small plastic switch added and the two part steering column and steering wheel can also be added.

When fitting the rear wall and roof it’s advisable to temporarily fit the doors to ensure the correct alignment of the wall/roof, the doors have additional small door handles and window winder handles and these need care in handling being very small but add excellent detail definition to the doors. The clear windows can be fitted closed or cut down to show partially opened windows if you wish and you can choose to glue the doors in the open or closed position as you wish.

Obviously the cab interior would need to be painted along the way and the completed sub-assembly can then be added to the chassis with two small lugs under the cab matching to those on the fenders for the proper alignment which shouldn’t pose any problems.

Once the cab has been attached to the chassis you can then proceed to glue the radiator in place on the chassis cross beam using the two hood side panels as ‘spacers’ to ensure the proper alignment with the radiator in place. The hood side panels have the louver slits moulded with fine gaps but you may want to open these a little more with a fine #11 blade to improve a little, the two top hood parts have inner hinges that fit together precisely along the centreline but the inner hinges on the lower edges and those on the side panels are best cut off as these just seem to hinder the panels mating together properly.

You can position the hood doors closed or folded open to show off the engine should you wish and there are more very small grab handle and latch parts added to the lower hood doors for excellent detail.

There are also the very finely moulded head light mountings and two part head lights with clear plastic ‘glass’ as well as the thin bar added between the fenders with the three part horn added and this delicate detail gives and very good air of finesse to the model but of course needs careful handing as they are also quite fragile.

Rear Tray:
The rear tray is basically five main parts, the floor and the four sides; all were moulded perfect without any warping and have simulated wooden slats with fine wood grain effect on both sides without any sign of pin marks anywhere.

On the underside of the floor are six small plastic hooks, the cross support beams and rear storage box parts that all fit perfectly without problems as do the upper sides, the central cross beam is actually added to the chassis and not the underside of the tray to make fitting the tray to chassis easier. The side panels have additional small plastic and etched brackets added and the rear gate can be fitted raised or lowered as required for a fairly simple and straightforward sub-assembly that then fits neatly to the chassis without problems.

Figures:
The kit includes two Russian driver figures both posed driving the vehicle so you have a choice of driver more than two crew. The figures are broken down in the conventional manner with separate torsos, legs, arms and heads with the two figures wearing standard Russian Army uniforms with field caps. The parts are cleanly moulded with just cleaning up the usual mould seam lines before assembly. Detail on the figures is nicely done and will come up well with careful painting although no weapons or personal gear is included with the figures.

Decals:
The small decal sheet has just a single number plate plus a couple of Russian stars and other white markings but there are no specific markings for the two German marking options provided while the painting guide in full colour has paint numbers given for Humbrol, Mr.Color, Revell, Tamiya, Testors and Vallejo paints.

The four options are:

  1. Unknown unit, German service, Eastern front 1941.

Instructions:
These are in booklet form which make it easy to move between stages and have the usual exploded view assembly sequences that in the main are well laid and easy to follow, there are a couple of areas that are confused with transposed illustrations as mentioned above. But taking the usual care of studying the sequences carefully before gluing shouldn’t pose any real problems even with the more complicated sub-assembles such as the suspension.

Conclusion:
As with the first GAZ-AAA truck this is an excellent kit of the later  GAZ-AAA Mod.1940 truck with very finely done details and some fine parts that result in delicate sub-assemblies (suspension) and the tyre segments giving excellent tread definition although the fit issue with the spare wheels on the new fenders is a little frustrating given these are the only new parts for the kit. The standard of moulding is also very high with virtually no blemishes or warping on the larger parts and the overall fit of parts very precise.

A couple of the areas need care as there is scope of miss-aligned parts if not careful such as the cab sides/top cowling and the fairly complicated rear suspension but due care should avoid any major problems.

The kit builds into a superb model of the GAZ-AAA Mod.1940 truck but is not for the inexperienced modeller due to some fairly complex assembly sequences and the fine parts included with the model applicable to many situations and scenarios as it was in service for much of WWII.

Rating 9/10
