Building block evaluation CaDA C61002 BM-21 rocket launcher vehicle

The prototype of C61002 is the former Soviet Union's BM-21 rocket launcher vehicle.

It was all-powerful in World War II.

For a time, the German soldiers were heartbroken when they heard this.

The BM-21 rocket launcher, nicknamed "Hail", was equipped with the Soviet army before 1964. The artillery regiments of the motorized infantry division and the tank division each have a BM-21 rocket launcher battalion.

It has the characteristics of fast launch speed and fierce firepower. It can also quickly switch between marching state and combat state, complete launch preparations in a short time, and has very strong cross-country maneuverability.

Mainly used to eliminate manpower and technical weapons in the assembly area; suppress enemy artillery and mortar companies; and destroy enemy field fortifications and support points.

The servo motor is finally here. This set gives two at once, but it’s a pity that there is still only one remote control. Next, let’s get the M motor or lithium battery box,

That’s MOC What players need most.

The box is so big, a great gift

After opening the big box, I found two small boxes, both of which were printed with numbers (indicating steps one and two). ), I have made some progress on this point. I remember that after taking apart the big box of the Double Eagle M1A2 tank I used to play with, the two small boxes were bare and had nothing printed on them.

Box No. 1 contains 10 packs of parts instructions. The digital printing on the bag is large and clear. There are warning slogans and maintenance methods on the bag.

The instruction manual is sealed in a separate bag, the stickers are very small, and the operating instructions and tips are on a separate piece of paper, which is convenient for players to check at any time, which is very considerate.

The three manuals include A and B modes. ***220 pages are clearly printed. The last few pages are a parts list. You can see that springs, small push rods, steering parts, etc. are all good meat-killing parts.

The No. 2 subpackaging step box contains seven parts packages and individually packaged PF parts.

This set has 7 tires. The tire size is 62.4*20R, and the tires are soft.

I have Lego tires of the same specifications just for comparison.

After comparison, we found that this tire has two shortcomings: 1. Compared with the soft and hard tires, Lego is indeed much softer.

At present, my car body has been assembled, and there is no load (missile mechanism) on the car body. So far, no impact has been found. I will add the load later to see if the tires can bear the load. ②The specifications (numbers and letters) on the tires are not as clear as Lego.

The click-fit wheel hub nozzle is well handled and hidden in the hole in the front wheel hub.

The processing here is better than that of Lego.

The focus here is on the servo (this model has two servo motors that are very good for killing meat, the Lego one costs nearly 200), the workmanship and texture are really satisfactory, and the huge click Lego, back to the point No problem

?, I also found a phenomenon, if the voltage is too high (the poster installed four 3.2V batteries, but it didn’t burn the receiver, it’s best not to try), the servo motor has protection to start, and the servo The orange shaft will skew from side to side or simply vibrate.

In the first few pages of the manual, I will introduce to you how to use all motors (including new private server motors). The one-to-one scale is very accurate. These are very friendly to novices. .

Now that the subcontracting step has begun, once the parts are spread out, there are quite a lot of them

Picture 1 and 2 are the unique technical parts of Kadai, with a beige 20-tooth structure. Slightly different from Lego's.

The one-to-one scale not only covers ordinary beams and shafts, but also includes the lengths of Kada's unique technological parts (I don't remember the Kada M1A2 tank yet). The instructions have improved again, and the assembly is completed. I think it’s really good that components are all displayed in gray. It’s not easy to confuse and is very friendly to technology novices.

The connection between the granular parts and the technical parts is tight and not loose, which is very good. In the past, the Arakawa small steel cannon of Pinmopin always had loose connection parts in the lithium battery box

?You know, the No. 1 receiver here controls the drive and steering of the car, and the L motor is responsible for driving the car.

It seems that there is no drive motor at the front of the car, and this model is a rear-wheel drive car.

Steering through black gear rack

Perfect combination

Car steering wheel and central control

Cab ceiling

The gray spring shock absorbers are very well made. They should be hard springs. It seems that the front-wheel drive of this truck also has a shock absorber structure.

The front bumper and hoses have scales.

Are the hood, rearview mirror, and servo motor hollowed out intentionally?

The overall suspension is a bit stiff

It takes a little strength to push me down

Personally, I think it would be better to use soft springs, because the weight of the car is mainly Back, light in front. Soft springs are more than enough.

Two differentials

The clutch gear protects the driving L motor

This is more complicated and I had to rework it once

The main thing here Rely on four red bolts to fix it. After it is fixed, you will find that there is a rocking effect. It seems that there is no rear suspension, so it can only be replaced like this

The next step is subcontracting step two. There are quite a lot of parts left in step one. No missing parts found yet

The large turntable is well made and rotates well, and the rotating platform is not very complicated

The small push rod is responsible for raising and lowering the gun mount. There is only one push rod. I want to push the gun Will it be too difficult to set up the set?

The second and third receivers appeared. The step-by-step instructions for threading this set are very detailed and not difficult.

The receiver and push rod are connected to the rotating platform and rotate manually

Here the clutch gear appears again and the L motor responsible for protecting the rotating platform (the second L motor appears and is responsible for rotating the platform )

I installed an L motor on the rotating platform and conducted a rotation test to see if the rotation was strong. It was indeed very smooth and fast, and the rotation angle was about 180 degrees.

The third L motor appears, responsible for driving the turret to rise and fall.

Testing the elevation of the turret, I can only say that the speed is slow

The second servo motor comes on stage and is responsible for firing the cannon.

The gun mount is gradually being improved, what a big chest device

There are 14 gun barrels, and Double Eagle also sent an extra gun barrel. This momentum is like a pear blossom needle in a heavy rain!

There are also a lot of ammunition, so let’s test it out quickly. Once loaded, a gun can be fired twice, seven rounds at a time.

Almost finished

The legendary spare tire is installed with a battery holder. The original poster used 3 cells of 3.2V lithium iron phosphate, which is light and powerful.

Let’s make a domineering appearance

Page 174 starts with the B mode. This time the B mode is very simple. You don’t need to disassemble the turret first to get the parts like building an M1A1 tank. To assemble B mode, the remaining parts can be directly assembled into B mode, because B mode is just a bucket

AB mode can be switched freely, and the steps are not complicated. Once you get started, you can switch modes in one minute.
