The classic design works from Arai Yen ranks fourth in popularity among all 26 MOC works published on the RB website. Like Xizheng, it is one of the most anticipated re-engraved works by the tech players. At the same time, it is also the largest MOC work of Arai Yen, with more than 4,100 parts, 2 lithium batteries, and 8 motors. It can definitely be called “Arakami Flagship MOC.”

Yuxing Mowang’s wild card has received widespread attention before it went on the market. Due to the large number of parts and the waste card is also a work worthy of careful reading and learning, this evaluation is expected to be completed in three parts.

The semi-finished products at the time of publication of the content of this article are as follows:

  • Packaging, manuals, parts subcontracting
↑ The color box is very large, still the standard design style of Yuxing. Due to the number of more than 4000 pieces of parts, there is no obvious space inside the color box, which is relatively compact.

 

↑ There are two sub-packaging boxes made of corrugated paper. Compared with the previously evaluated McLaren P1, Icarus, Xizheng and other Yuxing products that use color printing sub-packaging boxes, this wild card may be relatively more practical and cost-effective. Unanimous.

 

↑ There is only one manual, which is not as thick as expected. Although the number of parts in this waste card is as high as more than 4,000 pieces, in terms of the thickness of the manual, it is thinner than the 2500 pieces of Xizheng and Huanghang. The material and thickness of the manual paper are not significantly different from those of Yuxing\\’s previous products. Mainly because the manual has only 170 pages, while Xizheng and Huang Diao have 265 pages and 241 pages respectively.

 

↑ The assembling, layout, and printing of the inner pages of the manual are different from those of Yuxing\\’s previous products.

 

 

↑ There is no body sticker, only a sticker used to mark the motor and extension cord plug, very practical design. Judging from the feedback from previous players, the lack of cards is not too difficult in assembling, and there are no obvious difficult steps. However, due to the large number of motors and extension cords, it will take a lot of thought and effort to distinguish between motors and wiring. Be patient, so this sticker is very nice.

↑ A total of 12 parts are subcontracted, including 1 general-purpose bolt subcontract and 1 tire and wheel hub package. Like other products of Yuxing Mowang, it is still subcontracted step by step.

  • Power pack/PF parts

This Yuxing Wild Card is a power version by default, and there is no static version.

2 Bluetooth lithium batteries, 1 servo motor, 2 XL motors, 2 L motors, and 3 M motors . This is another super-luxury PF package! The number of Bluetooth lithium batteries and the total number of motors are the same as those of Huang Diao and Xizheng.

  • Driving: XL motor×2
  • Steering: Servo motor×1
  • Tail plate telescopic: M motor×1
  • Tail lift: M motor×1
  • Opening and closing of left and right cargo box doors: L motor×2
  • Front turning: M motor×1

In the original work, there is also an M motor used to drive the switch to control the LED lights. Yuxing this one has been removed.

Except for servo motors, XL/L/M motors are all “black burst” versions, and it is said that the speed and torque have been improved. Due to the lack of demand for motors, except for the 2 M motors I used the matching “black burst” motors, all the other motors were replaced with my own stock motors. (These “black burst” motors are reserved for a chance to test later.)

 

↑ There is Yuxing Mowang\\’s LOGO on the black explosion L motor.

In the original parts list and assembling guide, there are 3 sets of #61930 standard LED light sets (2 lamp beads per set) , of which 2 sets are used for headlights and 1 set is used for taillights. Yuxing’s wild card does not have a light set, so players who want light effects need to buy it by themselves.

I only have 1 set of standard LED lamp kits left in inventory, so I used Yuxing\\’s LED light bar here, which comes from the Yuxing poison I killed before, and the PF part of the Mercedes-Benz C63. Compared with standard LED lights, this kind of LED light bar has a lower brightness and is a bit more troublesome to install at the same time, but the advantage is that there are different light colors to choose from; and it can be lit by plugging in a lithium battery. The standard LED light group needs to be turned on by pressing the remote control; at the same time, each light bar has up to 4 LED lamp beads (you can trim it according to your needs) , and the matching special plug-in board can insert up to 9 light bars, that is, up to 36 light bars. Lamp beads, and only occupies 1 battery socket.

 

In addition, the total number of extension cords for this waste card is as many as 7. Two of them are 25 cm long and five are 50 cm long. I have not encountered so many extension cords in all the building blocks of the technology group I have done so far.

 


  • Part particles

Like other Yuxing products evaluated previously, except for tires, wheels and a small number of infrequent parts, almost all parts of this Yuxing card are high-brick parts.

The photos of some parts are as follows:

 

↑ Part of the thick hole arm adopts a new high-brick mold, and the glue inlet point is moved from the appearance surface to the side.

The following non-high brick parts may be Yuxing’s own molds:

↑ Out of print suspension drive axle, very smooth.

 

On the first day of shipment of the Yuxing Wild Card, a 32-unit long cross shaft was misplaced as a hose of the same length in terms of parts. After the manufacturer discovered the problem on the same day, it has unified arrangements for reissue. But because this cross shaft needs to be used in step 31, I used the 32-unit long carbon fiber cross shaft in the yellow crane.

 

This 32-unit long cross shaft is used for the lifting and driving of the tail plate of the truck. It is also a guide rail for the front and rear of the tail plate, so there is basically no large torque load. The carbon fiber cross shaft is not necessary.


  • Overall assembly experience (first half)

The first half of the assembling process took about 19 hours, including inspection of parts and photographs during the process.

As for the assembly feel, because of the basic use of high-brick parts, the feel is very good, representing the highest level of domestic building blocks.

After comparison, the manual is basically the same as the original PDF version of the electronic manual, and no obvious errors or omissions have been found (specifically, it will be mentioned in the “Key Items/Assembly Suggestions” below) .

However, this manual for the Yuxing Wild Card has these conditions:

★ On average, the density of parts in a single step is higher. This is not necessarily a shortcoming or advantage, I personally prefer this kind of instructions with high parts density. For example, a 1×1 bushing is used for 3 consecutive steps. For manuals with high parts density, because they are merged into one step, it is equivalent to a one-time search, and the efficiency of finding parts will actually be higher. However, due to different preferences and habits, some players may not like this design method, which varies from person to person.

Still comparing Huang Dang and Xizheng with about 2500 parts, Huang Dang has 2590 parts divided into 710 steps, with an average of 3.65 parts per step; Xizheng 2578 parts divided into 714 steps, with an average of 3.61 parts per step. The 4166 parts of the wild card are divided into 343 steps, with an average of 12.15 parts per step.

★ The design of some assembling steps is not perfect or the prompts are not detailed enough, so some steps need to be researched. This problem is also due to the fact that the manual is basically the same as the original MOC manual, so there are all problems with the original MOC manual. But from another point of view, it does not have serious errors or omissions caused by manual revisions and product magic changes.

In addition, apart from the problem of 32-unit cross shaft wrong parts, no other missing parts/wrong parts were found in the first half of the journey.

The above content is only for the first half. The complete assembly experience will be updated in the second part of this evaluation.

The approximate steps of the first half are as follows:

 

 

  • Important matters/assembly suggestions

The accuracy of this manual is very high, and almost no substantial errors have been found. The following are as assembly suggestions for reference:

★  Spell it slowly.

This car is an absolute shortage card worth reading and learning MOC works, it is highly recommended to stop from time to time, a closer look at its design, as Kevin Moo said, ” ….. only the best works of MOC Only then has the value of learning. The most important thing in this process is to think more and learn to guess the author’s intentions, why this part is used instead of other parts. ”

 

In addition, due to the aforementioned manual, too anxious and easy to make mistakes.

★ It is recommended to prepare some cable ties for wiring fixing.

In many MOC works, the wiring of the motor and extension cords of the wild card is not too difficult, but due to the large number of extension cords and the long wiring distance, it is recommended to prepare some cable ties to fix the wiring. Thinner is better, too thick ties will interfere with the assembly of parts.

Regarding the reference method of wiring, it will be sorted out in the follow-up evaluation.

★ Step 31, the 32-unit-long hose should actually be a cross shaft of the same length.

This problem is wrong in the manual. So, it\\’s not that the manufacturer misplaced the parts, but that the instructions were misplaced. I believe that the manufacturer will update this manual after the reprint, but before updating, be careful not to take the wrong parts.

★ In the 47th step, the original two clutch gears are modified into ordinary 24-tooth gears.

These two clutch gears belong to the lifting opening and closing transmission system of the door on both sides of the cargo box. The design intent should be to protect the push rod and the entire transmission system from damage when the push rod is hit to the end (similar to the yellow crane There is also a similar clutch gear design in the hoe lifting transmission system) . But because this small putter itself has a certain protection design, it is not easy to be damaged even if it continues to rotate after hitting the end, so it may be deliberately modified in consideration of this situation.

I am here in accordance with the original design, using clutch gears. In addition, since this place has not been fully tested yet, and the performance of ordinary gears has not been tested, it is impossible to determine the impact of this modification on the finished product.

There are some minor problems that have no substantial impact on assembly:

  • Step 12, the yellow outline of #32054 is wrong.
  • In step 13, the 8-unit long belt cut-off cross shaft is not pushed to the end in the figure, and 1 unit is left and needs to be pushed to the end.
  • Step 41, the other end of the #32293 connecting rod also needs to be installed on the ball head.
  • Step 78: The length of the cross axis is incorrectly marked and should be 10 units. The illustration is correct. It seems that the parts are equipped with 11 units, and it should be no problem with 11 units.
  • Step 79, pay attention to the vertical alignment of the rack and the cross shaft.
  • Step 90, pay attention to the vertical alignment of the servo motor cross shaft and the 2 sets of racks.
  • Step 134, one light gray #32184 is missing, and the opposite #43093 can be omitted.
  • In step 192, the direction of #32013 is reversed by 90 degrees, and the back is correct.
  • Step 246, #6536 shows the direction reversed.

The above, as long as you spell it there, you will understand; most players can find it by themselves, so the drawings are not explained.

There are no other issues that need to be specifically asked in the first half of the journey. However, it is best to test more when assembling. In addition, all gears should not be installed too tightly. As long as it is a complex transmission building block, these problems need to be paid attention to, and the lack of cards is naturally no exception.

 

In the latter half of the journey, as well as the final product, you can focus on the follow-up evaluation.
