Speaking of mechanical design, German engineers can be said to be very powerful. The industrial products they design and produce can be described as high-end and sophisticated. Correspondingly, the Soviet engineers had a different rough and heroic style. In their minds, the ideas that have been instilled in: simple structure, durable, reliable operation, convenient maintenance, convenient large-scale production, simple and easy to learn, etc., thus creating a large number of Soviet-era mechanical monsters in different fields, and MAZ537 is one of them.
MAZ537 is a heavy off-road military truck produced by the Minsk automobile factory in the Soviet era. It uses 8X8 full-time drive, fully independent suspension, an empty load of 22 tons and a traction load of 50 tons. A Kharkov-type D-12A-525A engine provides it with 525 horsepower, with a maximum driving speed of 55-60 kilometers per hour, with super passability and off-road performance. It was the main transportation and tow vehicles of military weapons and equipment such as tanks, aircraft, tactical ballistic missiles, cruise missiles and other military weapons and equipment during the Soviet period. Even in today's Russia, this vehicle is still using it as a transport tractor for tanks.
Excellent off-road performance, powerful off-road capabilities and solid reliability make the MAZ-537 not only leave an indelible memory in the history of heavy military vehicles of the former Soviet Union, but also play a great value in the civilian field. At the end of the last century, MAZ537 was exported to many countries for large-scale transportation, and MAZ-537 also appeared in Siberia and the Far East.
In the model circle, MAZ537 used to exist mainly in static models, especially with the 1/35th ratio of the trumpet player, the late-stage model of MAZ537G is more well-known.
Now, in the dynamic model circle, there is finally a MAZ537 model, which is the 1/12-scale BC8 military card model produced by Cross RC.
—— Unboxing part——
The real car of MAZ537 is equipped with a D-12A-525A engine, and the huge engine occupies almost most of the space on the front of the car, so the real car of MAZ537 is very large, which is also reflected in the model.
Cross RC BC8 has reduced the proportion to 1/12, but its size is still very huge, which can be seen from the dimension marking outside the packaging box.
Comparing the color box packaging of KKRC CA10 we have made before, we can clearly feel the hugeness of BC8. I wonder if the size difference between CA10 and after loading the car is so big.
BC8's size is also directly reflected on the beam. The length of 745mm can rank among the top in all retail military card model products!
BC8's tires are also large, with a diameter of 130mm. There are many tires of the same type on Taobao, so there are basically no need to worry about tire accessories in the future.
The wheel hub is a clamping wheel hub, and uses a universal 12mm bonding device, which is more convenient to replace other wheel hubs.
BC8 wave box uses two-speed transmissions, with gear ratios of 1:75 and 1:33 respectively. Low-speed climbing and high-speed cruising speeds are relatively suitable. The specific driving speed varies slightly depending on the motor and battery voltage used.
There are many other accessories, and I will introduce it to you one by one when it is assembled later.
—— Configuration part—
The car is good, and the configuration is naturally not bad. Except for the light group and three waterproof servos, the other electronic devices of this BC8 have to be equipped with their own. In order to make this car as real and interesting as possible when moving, we have prepared the following configuration for it.
. Haoying AXE Kaishan Axe Power Set
Haoying AXE Kaishan Axe Power Set is a special brushless power set for climbing cars released by Haoying during the Beijing model exhibition this year. Its features high torque, strong power, power saving, and the parameters can be adjusted using Bluetooth-connected APP. For detailed reviews of Haoying AXE Kaishan Axe Power Set, please click the blue words below to jump to view.

BC8 is relatively large in size and is not light in weight. Even the low-end plastic parts are close to 20 kilograms after installation. Ordinary brushed power may still be a bit difficult for this weight. Based on power considerations, I finally chose the Haoying AXE Kaishan Axe 1800KV power set, which can maintain high-speed cruising and low-speed torque. In fact, after loading the car, I found that even with high-speed gear, the BC8 equipped with the Haoying AXE Kaishan Axe power set also has very strong low-speed torque, and the power performance is very strong.
. Canshuo CS-RC16 sound group
This time, this time, I chose to use Canshuo CS-RC16 three-in-one sound and light group. The sound effect of CA10 can be perfectly compatible with MAZ537.
At the same time, in order to get better sound effects, the audio has also been changed to a 10w full-band 2-inch audio, which has a very good loading effect.

.Killerbody Smoking Box
Killerbody What everyone is familiar with is that the car shells are a little more, but in fact, Killerbody also has many car mold accessories. The characteristics of this Killerbody's smoke box are that it produces a large amount of smoke. Compared with the engine smoke in some MAZ537 startup videos on the video website, I finally chose this smoke box to try to achieve the desired effect.
.ASSAN 10A Dual-way UBEC
There are more electronic devices on the car, and the battery requirements are naturally increased. The power of electric-controlled BEC is obviously unable to meet the growing energy consumption, so external BEC has become an indispensable device.

This ASSAN UBEC can support four levels of voltages: 8.4V, 7.4V, 6.0V, and 5.2V, with a maximum current of 10A. It should be more than enough to deal with the three shift servos, sound groups, light groups, smoke-emitting wave boxes and two 10W speakers on this car.
—— Painting and making ——
Painting and making can be very simple or complicated for a car. In order to make the car look more realistic, this time the painting production chose a complex approach, but the specific process is actually very simple, all of which are the most basic soil repair, spray paint, filters, and old-fashioning and special effects.
so the final effect is like this. Let’s give some simple explanations of the process and some details below.
First of all, the assembly of the car shell, just assemble it in this state according to the instructions, but remember not to install glass at the beginning!
Overall, the workmanship of the shell of the CROSS RC car has improved, but in general, it is still not satisfied, especially the moving parts and interior after assembly. All movable parts of BC8 are very flexible after assembly. Although this is a very good advantage in some cases, it does not seem to be too flexible for parts such as the rearview mirror that need to be fixed; the other is the car door, which does not have a fixed position, and after opening the door, it will interfere with the rearview mirror to further maintain the angle of the rearview mirror. In terms of interior, BC8 is even more simple, with obvious internal wiring, so it takes some effort to hide internal wiring.
There is another obvious bug. After the interior assembly was completed, it was found that the gap between the original steering wheel and the door was too small, so the steering wheel, gear lever and foot pedal were moved a little to the right side of the cab.
of course, it is not all bad. When BC8 is doing well, the dashboard, the hollow dashboard plus the stickers and LED lights below can make the interior atmosphere of BC8 better. This should be a thumbs up.
The specific process of spraying paint will not be described here. Those who want to learn the basic process of painting and painting production click to read the original text and travel through time to learn!
After the spray painting is completed, you can first set some parts (no screws) and prepare to start the wiring of internal electronic equipment and the installation of the light set. The hub shell of
BC8 is very interesting and can be screwed directly on the outside of the hub. It is very convenient to install and disassemble. While ensuring that the tire is installed firmly, the hub shell can also make the entire tire look more simulated. The back saddle bag of
MAZ537 was originally used as a accessories box, but the BC8 in the model is used as a powered cooling chamber. However, for Haoying AXE Motor, such a large heat sink is still a bit useless.
So here the cooling fan was removed and replaced with the speaker's sound room.
As for heat dissipation, the AXE motor itself is not too heated, so it will be done by handing it to the heat sink below. If it really doesn't work, adding a small fan on it can also effectively improve the heat dissipation conditions of the motor.
Maybe some people will say: The motor and the speaker are so close together, will there be no abnormal sound when the motor is working? In fact, this problem is different. First of all, the magnetic field interference of the AXE motor itself is not too strong, and the speaker we choose is also an anti-interference speaker, so it is not affected at all during actual operation.
Then there is a smoke-emitting wave box, installed on the chassis of the car, and a Y-shaped tube is made to divert the flue.
The chimney on the car shell is sealed with an ABS board, and is connected to the smoke-emitting tank below through two hoses that can be quickly disassembled. At first I was quite worried that Killerbody's smoke-burning bin could not support such a large two chimneys, but after installing it, it worked well.
smoker box is supplied from the outside and is connected to a small bottle in the audio room by a long hose. The capacity of the small bottle is about 15 ml, and basically a small bottle can smoke continuously for several hours. Moreover, the Killerbody smoker is not picky about food. In addition to the original smoker, the smoker like Henglong can also smoke in large quantities.
The following layout is done, and the next step is to install internal equipment and local wiring. The front of the MAZ537 is very large, and the internal space is mainly used to install engines and engine heaters (you know how to work in Siberia). So when it comes to the model, the BC8 with less engines is very abundant, but it is still not too presumptuous when laying out the equipment.
BC8 The original audio room was used to play receiver, sound set and BEC circuit board. The original light set size was too large under the seat. Each electronic device is waterproofed with three-proof paint, and there is no worries about wading in the future.
In order to better utilize the space, the electric drive is placed between the gear shift servo and the original audio room, and the position is just right.
After the basic layout is completed, the wiring and wiring work will be done. Although there are many electronic devices in this BC8, the lines that need to be connected are not complicated in fact. The throttle control channel passes through the BEC diversion plate, and simultaneously controls the throttle linkage of the sound group, electric regulator and smoke-emitting wave box; the steering channel uses Y-wire to connect the light group and the first pair of steering wheels, and the six channels and one channel are proportionally mixed to connect the second pair of steering wheels to realize the linkage between Ackerman steering and lamp groups.
Later, actual measurements found that the BEC of the electric-controlled instrument is not enough to support the power supply of so many devices. When steering again, it will cause voltage unstable and cause sound group abnormal noise, so an additional external UBEC power supply is added to perfectly solve the problem of voltage unstable. But it is a bit troublesome to turn on one more switch when switching on the power supply in the future.
This BEC diversion board is a board provided with the vehicle. Its original function is to divert the control line of the servo. However, the steering angles of the two servoes in this way are the same, and the Ackerman steering angle cannot be realized, so the proportional steering setting directly uses the mixed control function of the Lodi RC6GS gun control, and this board has also been slightly improved and has become three control lines used by the BEC diverter board to connect the throttle.
Lydie RC6GS gun control Ackerman steering hybrid control setting principle is achieved by controlling the angle difference between the two steering servos in front and rear, as shown in the figure above: the host is set to "servo", the slave is set to "six-way", and the ratio on both sides is set to 80%.

When steering, the steering angles of the front and rear tires will form an angle difference, and the two steering wheels in the front and rear can realize the Ackerman steering principle, making the turning radius smaller and the steering smoother.
first perform the old processing before installing. In order to facilitate internal wiring, a wire slot was made in the middle of the front of the car, which was sloppy.
With this cable trough, all traces inside the car shell can pass here to reach the rear equipment cabin, and have no effect on the beauty inside and outside.
To facilitate future maintenance, the fixing of the car shell was not glued to death, but was fixed with screws.
While installing the car shell, the wiring of the light group is also carried out at the same time. The turn signal uses a light group attached to the car for linkage. The headlights, roof lights, dashboards and interior ambient lights are all used for flashing CS-RC16 lighting lines.
The last BC8 light + smoke effect is like this, and the loading review of the whole vehicle ends here.
—— Summary—
In general, this BC8 can be regarded as the best one made so far among all the military cards of CROSS RC. It is very well-made, accurate, structure, and details, especially the adjustment method of the median steering of the turf is even more ulterior motive. The assembly process was also very smooth and there were almost no difficulties. It is worthy of being a manufacturer with many years of experience in manufacturing military card models. However, the production level of the car shell remains at its original level, and there is basically no progress, especially the design of the moving parts, which looks more like the setting of the static model player. If you want to be more worry-free in playing, you have to spend a lot of time doing DIY improvements.
