As one of the four flagship sports cars of Lego, Lamborghini 42 1 15 has 3696 parts and two manuals, with a total of 1084 assembly steps. The whole process needs good concentration and patience, especially when assembling the internal mechanical structure. If you make a mistake, you will have to rework it if you are not careful.

Precautions:

When assembling, be sure to confirm the size, position and direction of the parts according to the instructions.

In steps 14 and 222, attention must be paid to the direction of the front and rear wheel differential, otherwise the pullback effect may occur.

Step 134 The position and relative direction of the internal parts of the gearbox should be consistent with the manual, otherwise, the 12 speed transmission is likely to be stuck.

In step 247, the black part of this double hole is made of soft rubber, and the whole box has only one piece. Don't use it wrong.

After assembling the remaining parts of each component box, if there are any spare parts, they are basically missing parts. In addition, Lego generally does not have missing parts. If some parts can't be found, it is necessary to check whether there are any wrong parts used in any step.

Extended data:

The first box summary:

After putting the rest together in the first box, I watched everyone share it. In the end, I didn't use seven small parts, and the rest of the boxes and black and red bars will be used later.

Installation is error-prone:

Step 96: Pay attention to the direction of the orange part and get stuck between the gray screws.

Step 134: First, pay attention to the unified direction of the orange part, and then pay attention to the splicing direction of the green part! I misspelled it the first time, but fortunately I found that I couldn't turn it when I tested it, and I changed it back in time. Only when I turn it, the two small gray buttons inside are correct.

Summary of the second box:

Step 205: Pay attention to the three buttons in Figure 2, which I found when I spelled later, but it didn't have much effect.

Step 247: Note that it is a ferrule made of soft rubber, not a small hard building block.

Step 280: Note that the small red button of the shift paddle should be stuck between the gray spiral knobs! Remember to rotate the yellow gear after installation to see if it can be linked. Mainly four wheels? Can the black wheel and the black cylinder in the middle rotate together? I checked this step by watching a video sent by a blogger.

The third box summary:

Third, it is much easier to put together, but there is a sad news that the parts are packed in the wrong part. At first, I thought I made a mistake, but then I checked the book again, and there was no problem. Finally, a red part with a left fork and a right buckle is missing, and a red part that is not needed for this assembly is added. Start from the fifth package and make up first.

It should be noted that

Step 4 15: The armrests on both sides of the seat have part codes, so don't install them backwards.

Steps 454-455: The small blue button is stuck in the first hole, and in step 455, it is stuck in the second hole. Please refer to the side view.
