"Boss, look, all the parts have been built according to the requirements of the design drawings!" In a small workshop of the Daqian Food Factory, several people in work clothes surrounded Jia Yapeng, and Jia Yapeng sat on a workbench, looking at the various parts scattered on the table in front of him.
"Haha, I haven't played with this thing for at least ten years. It's really nostalgic to see it now!" Looking at the familiar and unfamiliar parts on the table in front of him, Jia Yapeng couldn't help but sigh.
"Oh! Boss, did you already play with the 4WD when you were in your teens? " An old man in his fifties said with some doubts, "But that's not right. The 4WD was invented in Fusang in 1983. Where did you play with the 4WD ten years ago? Was it the developed version of Tamiya? "
"Haha, I'm just kidding!" Jia Yapeng laughed. The ten years ago he said was ten years ago in another world, when he was only 15 years old.
"Come, let's see if my competition-level assembly skills are still there!" Jia Yapeng smiled slightly, and the chassis appeared in Jia Yapeng's hands in an instant, then the gears, the shaft, the motor, the motor cover, the guide wheel, the spacer, the rubber guide ring, the phoenix tail, the switch, the axle, the wheel hub, the tire, and finally the car cover and the spray button.
In less than five minutes, a complete 4WD was assembled in Jia Yapeng's hands.
"Oh my God …" Seeing this speed, the bank's staff who made the model car were all dumbfounded.
Although the model car was made by hand, step by step, and every part was polished by them, if they were to assemble it by hand, it would be impossible to complete it without more than ten minutes.
In the end, Jia Yapeng used at most four minutes to assemble the 4WD successfully. This was simply a miracle. Could it be that Jia Yapeng had assembled the 4WD countless times?
"Don't be surprised. In fact, in Japan, there is already a very systematic 4WD competition. One of the competitions is 4WD assembly. The competition is to see who can assemble a standard 4WD as fast as possible!"
"It's been a long time since I've assembled a mini 4WD. My speed has slowed down a lot. When I was at my peak, I could assemble a mini 4WD in about three minutes. The record in Japan was set by a player in 2009 … '89. He only used one minute and two seconds to assemble a mini 4WD, including the time it took to put the sticker on the hood of the mini 4WD!"
"So put away your shocked expressions. Otherwise, if you see those record holders in the future, your jaws will drop!" Jia Yapeng laughed loudly, and the staff laughed along.
"Come, let me try and see how fast this 4WD is!" Jia Yapeng flipped the switch, and a loud roar of the engine began. The four wheels of the 4WD began to rotate at an extremely fast speed.
"This motor won't work!" Jia Yapeng listened to the sound and shook his head. "The coil material of the motor is too little. This motor won't be able to speed up. It needs to be coiled by at least a third or so!"
"There's also a problem with the degree of bite between the gears. The noise is too loud. It won't take long for the gears to break!"
"Wait … Why is there a burning smell? Did I forget to apply lubricant just now? Or did you not provide any lubricant at all? "
"This won't work. In the future, you must put a small tube of lubricant in the product. The bite of each gear must be smeared with lubricant. Otherwise, the 4WD won't last long!"
"…"
In less than ten seconds, just by listening to the sound and smelling, Jia Yapeng pointed out more than ten flaws in the 4WD in one breath. This made the staff feel ashamed and shocked.
He was ashamed of the fact that there were so many flaws in the experimental product that he thought was foolproof. On the other hand, he was shocked at how familiar his boss was with the mini 4WD. He was actually so much more skilled than his own research and development staff. This was too awesome!
"Have you forgotten that the blueprints and design drafts of the 4WD were originally drawn by our boss? Our boss is the best 4WD expert in the whole of Hua Xia. Our boss's ability is naturally not something you can compare to! "The old man on the side scolded.
"That's enough, Old Li. I'm a little embarrassed by your bragging. I just used to play with it more in the past!" Jia Yapeng laughed. "Right, is there a racetrack? Let's see if this car can run! "
"Yes, it's already prepared!" Old Li brought Jia Yapeng to an open space where a winding circular racetrack was already set up.
"You actually used iron plates to build the racetrack?" Seeing the material of the racetrack, Jia Yapeng exclaimed.
"We had no choice. We also know that it's cheaper to use plastic racetracks, but the mold for the plastic racetrack is more troublesome. It can't be made in a short time, so we temporarily welded one with iron plates!" Old Li explained.
"Sure, this is my first time racing on an iron plate racetrack, hahaha!" Jia Yapeng laughed and put the car on the racetrack. The car immediately began to run wildly on the racetrack.
"Success! We did it! "Seeing the car running so happily, the surrounding staff immediately cheered. One must know that in order to build this small 4WD, they had worked for a full three months. It was really too hard.
But the staff's cheers didn't last for more than a few minutes. The car suddenly stopped on the racetrack and didn't move.
"What's wrong? Did it run out of battery? "
"Impossible, two # 5 batteries should be able to run for at least half an hour! It's only been a few minutes, how could it run out of battery? " Everyone froze. One of the staff immediately went forward to take the 4WD and checked it repeatedly, but he couldn't find anything wrong with it.
"There's no problem, it's on the copper plate of the switch!" Boss Jia shook his head. "It's obvious that the copper plate of the switch you used isn't flexible enough, and the curvature isn't large enough. After a long time, coupled with the impact of the racetrack, the switch won't be in good contact, and naturally the power will be cut off!"
"This is very important. You must find a way to adjust it for me. Make sure that the copper plate of the switch can maintain its flexibility for at least a month. Otherwise, our reputation will be ruined!"
"It's true, the copper plate of the switch won't be in good contact!" Hearing Boss Jia's words, the inspection staff moved the copper plate slightly, and the car started to run again.
"Boss! You're simply too amazing! " This time, all the staff looked at Jia Yapeng as if they were looking at a god. How familiar was their boss with the 4WD that he could find the problem without even touching it?
"Tsk, when I was playing with 4WD cars, I lost count of how many times I was tricked by the copper plate of the switch!" Jia Yapeng shook his head, recalling the story of when he first started playing with 4WD cars.
At that time, the quality of the 4WD cars, especially the domestic ones, was extremely poor. The main problem was the copper plate of the switch. At first, it was fine, but after playing with it for a long time, it would not be flexible enough, and all sorts of power failures would follow.
At first, Jia Yapeng didn't understand so many problems. He thought that the battery or motor was broken, and didn't know how many batteries had been tricked, and how many 4WD cars had been replaced. Later, he found out that it was a problem with the copper plate of the switch from one of his friends who also participated in the race.
Those racing 4WD cars had to be assembled from specialized shops to purchase race-grade copper plates of the switch. Otherwise, if the 4WD car suddenly stopped during the race due to a power failure, it would be a loss for sure!
In just a few seconds, they would be left behind by a few laps.
These experiences were all obtained by Jia Yapeng in his previous life!
