Transmitter-
The transmitter is small, with push button controls, and a pistol grip. The antenna
extends, and the pistol grip houses a 9 Volt battery and removable 27mhz frequency crystal. A corresponding crystal is located
under the tank's turret. 6 different crystals are available in the 27mhz band allowing up to 6 Tokyo Marui tanks to be used
at the same time. On the upper right of the transmitter is a red LED. It should
normally be a bright red color. If it becomes a dull red glow, replace the 9 Volt battery. It is indicative of insufficient
power to control all of the tanks functions.

Note the removeable transmitter crystal, and the tank's brass antenna insert collar |
|
The reciever crystal is located under the right turret rear |
The Abrams receives
transmitter control data from the right antenna only, the side with the frequency crystal.
2 antennas are included, one for each side of the turret. The antennas are about 12 inch long each with a tightly wound
base, and loop at the end. The antennas appear to be chromed steel items, and are fairly flexible. You can put a permanent
bend in them if you are not careful.
Using
the transmitter, the Abrams is able to operate on more then one channel. This means the tank can move, rotate its turret and
shoot the main gun, all at the same time! The transmitter range for me is about 100 feet; at that distance the model is quite
small indeed.

Push-button transmitter allows for one-handed operation |
Operations-
Out of the box, the M1A2 Abrams is almost ready to run. Remove all the attached warning tags, insert antennas,
and batteries, and the tank is ready for play. You can leave off the details parts for later. The tank on/off switch is found
on the bottom of the hull. The push button transmitter is quite intuitive to
use:
To move forward, press
button #1. Both tracks will operate in unison. Pressing button #2 or button #3
will increase forward speeds.
To turn left, press button
#L1. Button #L2 will increase left turn speeds. Turning right is accomplished with buttons # R1, and #R2.
The Abrams can drive backwards
as well. Push button # BACK to move straight backwards. To turn left while moving backwards press button #LB , and to turn
right while moving backwards press button #RB .
The model can also turn
in place, just like a real tank. Press either a forward left and a rear right button or forward right and rear left button
in unison. It's a little too quick to be realistic, but it's useful should you need to make a panic turn in the opposite direction.
Unlike the larger and more sophisticated Tamiya tanks, none of the movement is proportional. The tank is either at a standstill
or moves at any of three forward speeds. In most cases, the Abrams looks most realistic moving forward or turning at speed
#1.
As with most R/C vehicles,
it is a good idea to let the tank come to a complete stop when switching between forward and reverse gears. This prevents the gears from stripping or wearing out prematurely. You can switch between the forward speeds,
and left/right turn quickly with no worry of damaging the gearbox.
Turret rotation is
accomplished by two left or right buttons. The turret turns about 320 degrees, when the main gun begins to pass over the rear
engine deck, you should stop. Continuing to rotate the tank turret past this point will result in ugly gear clicking noises!
Likewise, the main gun can be elevated or depressed with a single button. Pressing and holding down the button will move it
on one direction. Releasing the button and pressing it again will cause the 120mm cannon to move in the opposite direction.
Holding the button down continuously will result in the gun moving up and down in a continuous cycle.
The Abrams with the separate
link replacement tracks can drive over low shag carpets indoors, on hard tile, and concrete sidewalks. The Japanese instruction
booklet has cute diagrams that illustrates you should not drive on grass, sand or water. I have driven the Abrams on grass
and soil with no problems, but sand and water can be harmful since the hull is not weatherproof.
Some of you may have read the somewhat disappointing review of the off-road capabilities of Tokyo Marui's previous
tank, the Type 90. According
to the reviewer of a popular Internet electronics site, the Marui Type 90 encountered alot of difficulties
traveling on grass. This
is not the case with the Marui Abrams. The drive motors are the same but geared differently. In addition the track segments
have a longer center guide that fits deeply into the drive sprocket, giving better torque than the Type 90.
Tokyo Marui states in advertisements, that their tanks can climb 35 degree slopes. My Abrams can actually climb
up to 50 degrees incline on a particle board surface!
The Abrams has enough power to climb over untrimmed lawns, and up grassy slopes with authority. A video of my
Marui Abrams easily traversing grass is available for download at the Yahoo Marui Tank Group webpage (see the links section). A twig trapped in the drive sprocket will still require
removal though (this can disable bigger Tamiya 1/16 scale tanks too)!
If you take your Airsoft tank off-road, be sure to open the hull to inspect the spring suspension, electrical
connections, and clean out debris inside the hull, and drive sprockets. This should be done about once a month or when
necessary.

The Marui Abrams can climb 50 degree inclines and grass as well |
Airsoft
mechanism- One of the biggest appeal of Tokyo Marui tanks is that it can shoot plastic BBs. The instruction
booklet constantly reminds you to play safely with Airsoft tanks, and wear eye protection. The Airsoft mechanism is very powerful
and should be treated with respect like an actual firearm. Always remember:
Never shoot at people, small animals, glass or property with the tank's main cannon!
|
Marui 6mm bbs |
Internally, the gun barrel
is metal, with a cosmetic plastic sheath resembling the M256 smoothbore cannon of the actual Abrams. A single 130 size
Mabuchi motor is used to power the Airsoft mechanism, which works
by pulling back a piston inside the tank. A single 6mm BB loads into the chamber, and the piston is pushed forward by a tight
spring; the resulting increase in air pressure propelling the BB 50-75 feet away. About 45 BBs can be loaded into the
tank by opening (appropriately enough) the loaders hatch on the turret. Push the gun firing safety switch to the ON position
(located inside the loader's hatch). On the transmitter press the two red "FIRE"
buttons at the same time. One is on the transmitter front, the other is under, on the pistol grip. You will then hear the piston pulling back, and a red LED warning light on the turret co-axial gun will
glow bright red. The main gun will then fire the 6mm BB ! You will probably not
see the BB exiting the gun barrel, as it ricochets at high speed off walls! The continuous rate of fire is about 1 BB every
2 seconds.
|
The LED gives 2 seconds warning, before the main gun fires |
|
The Airsoft gun's on/off switch is under the loader's hatch |
|
Do not purchase low quality bulk packed BBs |
Care should be taken with
6mm BBs. The correct ones are high grade plastic, 0.12 gram weight. You should check the BBs are perfectly round with no mold
lines, scratches, or pitting. Using such faulty BBs can damage the Airsoft mechanism. Never use metal BBs or 6mm paint balls.
The metal will damage the gun barrel, and the paint balls can break inside the main gun tube resulting in a very messy clean
up!
|
Note the circular impact, and bruising underneath |
Tokyo Marui has incorporated
a "Hop-Up" system that produces a backspin to the BB; the increase in lift enables it to travel out to 75 feet. Due to its
light weight, the 0.12 gram BB has a habit of rising up after leaving the gun barrel, before dropping back down. Tank
to tank combat is difficult since the 0.12 gram BB travels 8-10 inches off the ground, well over an opponent's turret
top. Members of the Yahoo Marui Tank Group (see link) have reported
that heavier 0.20 gram BBs negate the effect of the "Hop-Up's" backspin, allowing it to travel straighter. The 0.20 gram BB
travel about 4 inches off the ground, the perfect height to combat another Airsoft tank!
In case you are wondering,
the BBs can shoot through thin cardboard, knock down empty beer cans, and at close range, painfully bruise skin.
Average velocity is 200fps, approximately 0.2-0.8 joules of energy. So play safe!
In summary, the Tokyo Marui
M1A2 Abrams is a wonderful pre-assembled and painted toy, with basic radio control function, impressive details and accuracy,
combined with an internal Airsoft gun. It is a great introductory tank for those who are new to the hobby. If you are interested
