1⁄16Trumpeter M16 Halftrack
IntroductionThe US M13 was an M3 Half-track with hinged rear flaps that folded down, and an electrically powered Maxson twin .50caliber gun turret on the rear bed. The M16 was the M13, but with a quad .50cal Maxson mount. The M16 was the standard anti-air vehicle for the US Army to the end of WW2. During the 1950s, Monogram released a 1/35 M13 kit with dual .50 calibre guns. In the 1970s, Tamiya released its classic 1/35 M16. Dragon did not release its superb M16 kit until September 2008. I have been excitedly anticipating the arrival of Trumpeter’s 1/16th M16 as much as anyone has, especially after building all of Trumpeter’s 1/16th scale T-34 series. I ordered this kit and booked time off work. Ah…some people holiday at the beach –not me. To say this kit is big is an understatement. No need to cover the same ground as Toadman in his overview of the over 726 parts contained in the box. Suffice to say this kit is a massive project.

ConstructionChassis Chassis Construction begins with setting the gearbox and cross members between those sturdy metal chassis members or, frame rails. Confusingly, part Z28 is installed during step #6, but is shown as already installed in Step #1. Caution: do not cement anything at this stage; loosely locate the parts using the screws provided. I use a bit of gummy “Blue Tac” on the head of the screw to start it in the threads (See photo, Below) It’s important to get the front of the frame rails parallel and the correct distance apart, or you’ll have grief later when installing the winch in Step 7. Take a break and construct the winch and exhaust assembly, the later being held to the frame rail with a long screw. Very clever, very easy. Don’t be a perfectionist about the seam you’re left with after assembling the axles (parts B5/B6). Remember, those axle cases were cast as a single unit, and have a rough seam. Screw the axles and leaf springs on: again, don’t commit to the super glue yet! The front wheel will swivel by use of rubber cups between the axle ends and steering knuckles (See photo, Below). A word to the wise: that very long drive shaft (parts Z46 and Z45) must make a perfectly straight line between the transfer case and the winch. A15 and A18 are inner tubes for the front tires, but are entirely unnecessary –omitting them will make insertion of the front wheel rims (parts U13 and U 14) much easier: I clamped the rims together inside the tire using a C-clamp from my desk lamp while the super glue dried. After engine installation, the PE stone guards (PE 20 and 21) may be installed. The appropriate bends to make are vague in the instructions –so you’ll have to guess-timate the angles. Step 11 concerns construction of that robust front bumper. Use a pair of spring clamps to get all the brackets square and at right angles to each other (See photo, Right). A slip-up here will be very noticeable! Start on construction of the bogies. The suspension is not intended to be "workable". Enlarge the two holes in part A1, and insert the springs (parts U1) as your first step. Sixteen rubber tires are provided for the eight road wheels. Each tire has a groove that should face inward. Do not over-tighten those screws! Again, locate all the finished sub-assemblies onto the chassis using screws, not glue. Note that the tube (part # A12 ), connecting the bogies, is too long: I sanded about 2 mm off each end (Fig. 5). Two are provided in the kit, so don’t be too nervous. Once everything is installed to the chassis, the major sub-assemblies can be cemented with super glue. This will ensure strength. The outside face of the sprocket drive wheels are cursed with injector pin marks unfortunately placed between each strengthening rib. A smear of putty for each will make this hardly noticeable, once some heavy weathering is applied. Install the sprockets and idler wheels, the drive sprockets I affixed by super-gluing part A16 to the axle case. This will provide some strength, as the tension in those rubber tracks will put great strain on the whole assembly. Tracks Flatten the lengths of track as you gently warm them with a hair dryer. Although no clue is given in the instructions, yes, they’re archaic rubber band affairs employing the age-old connection method of pins you mash-down with a heated screwdriver (See photo, Below). But surely not? Is this really the year 2008? Since the tracks on the real vehicle were metal with rubber “endless belt” casings vulcanised onto them, these tracks will actually look okay. The inside of the tracks have no detail, however. Mine had nasty flash on most edges where they seem to have been carelessly torn from their sprues. I’d much rather have had them come still attached to the sprue, rather than neatly rolled inside a box! Though there is really no sag in these tracks as in conventional “link” type caterpillar tracks, I used wire to snug the track to the idlers and sprockets (see photo below). With the tracks connected, fit them around the sprocket, road wheels, and halfway around the rear idler wheel. Gently rotate the idler and ease the tracks around. Worry not; the whole suspension assembly is sturdier than it appears. Now you can see why it is static, rather than working.
