"Boss, look, all the parts have been made according to the design drawings!" In a small workshop of Daqian Food Factory, several people in work clothes surrounded Jia Yapeng, who was sitting 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!" Jia Yapeng couldn't help but sigh as he looked at the table of familiar and unfamiliar parts in front of him.

"Oh! Boss, have you already tried a four-wheel drive when you were more than 10 years old?" An old man over fifty years old said with some confusion, "But that's not right, four-wheel drive was only introduced in Fuso in 1983.

It was invented. Where did you play with a four-wheel drive ten years ago? Is it a development version of Tamiya?"

"Actually, it happened seven or eight years ago. When Tamiya first launched its four-wheel-drive vehicle, my father brought one from Fuso to make a toy for me. It was my best toy!" Jia Yapeng told lies seriously.

"Come, let's see if my competition-level assembly skills are still there!" Jia Yapeng smiled slightly, and the expected chassis instantly appeared in Jia Yapeng's hands, followed by gears, shafts, motors, motor covers, guide wheels, and pads.

pieces, rubber guide rings, fins, switches, axles, hubs, exposed tires, and finally the car cover and injection buckle.

In less than 5 minutes, a complete four-wheel drive vehicle was assembled in Jia Yapeng's hands.

"Oh my God..." Seeing this speed, the nearby workers who manufactured this model car were stunned.

Although this model car was made step by step by hand, and every part was polished by them, if they were to assemble it by themselves, it would not be possible to assemble it in less than ten minutes.

As a result, it took Jia Yapeng more than 4 minutes at most to successfully assemble a four-wheel drive vehicle. This was simply a miracle. Could it be that Jia Yapeng had already assembled four-wheel drive vehicles countless times?

"Don't be surprised. In fact, there is a very systematic four-wheel drive competition in Fuso. One of the competitions is four-wheel drive assembly. The competition is who can assemble a standard four-wheel drive car the fastest!

"

"I haven't assembled a four-wheel drive vehicle for a long time, and the speed has slowed down a lot. When I was at my peak, I could assemble a four-wheel drive vehicle in about three minutes. The record at Fuso was set by a player in 2009...

...Created in 1989, it only took 1 minute and 2 seconds to assemble a complete four-wheel drive vehicle, which even included the time to put the sticker on the hood!”

"So put away your shocked expressions, otherwise if you see those record holders in the future, your jaw will be dropped!" Jia Yapeng laughed loudly, and the staff members started laughing along with them.

"Come on, let me try and see how fast this four-wheel drive is!" Jia Yapeng flipped the switch, a loud engine roar started, and the four wheels of the four-wheel drive began to rotate at an extremely fast speed.

"This motor doesn't work!" Jia Yapeng listened to the sound, shook his head and said, "The number of coil materials in the motor is too small. If the speed of such a motor cannot be increased, at least about one-third more coils must be wound!"

"There is also a problem with the engagement between the gears. The noise is too loud, and the gears will be broken into pieces in a short time!"

"Wait...why does it smell like burning? Did I forget to apply lubricant just now? Or did you not provide lubricant at all?"

"This won't work. In the future, a small tube of lubricating oil must be put into the product, and lubricating oil must be applied to the bite of each gear, otherwise the life of the racing car will not be long!"

"..."

In less than ten seconds, just by listening to sounds and smells, Jia Yapeng pointed out more than a dozen defects in one go, leaving the staff both ashamed and shocked.

I was ashamed that the experimental product that I thought was foolproof actually had so many flaws, and I was shocked by how familiar my boss was with four-wheel drive vehicles, and that he was so much better than the R&D staff like myself. This was so awesome!

"You have forgotten that the drawings and design drafts of the four-wheel drive were originally drawn by our boss. Our boss is the best four-wheel drive master in China. Naturally, the boss's abilities are not comparable to yours!" the old man on the side scolded.

road.

"Okay, Lao Li, I'm a little embarrassed that you're bragging. I just played more in the past!" Jia Yapeng laughed. "By the way, is there a runway? Let's run this car and see!"

"Yes, we have already prepared it!" Lao Li took Jia Yapeng to an open space, where a winding circular track had been set up.

"You actually used iron plates to build the track?" Jia Yapeng exclaimed when he saw the material of the track.

"There is no way. We also know that plastic tracks are cheaper, but the molds for plastic tracks are more troublesome and cannot be made in a short time, so we temporarily welded one with an iron plate!" Lao Li explained.

"Okay, this is my first time racing on a tin track, hahaha!" Jia Yapeng laughed and put the car on, and the car immediately started running wildly on the track.

"Successful! We succeeded!" Seeing the car running so happily, the surrounding staff suddenly cheered. You must know that they have been working for about three months to build this little four-wheel drive.

, it’s really too hard.

But the cheers of these staff members had not lasted for a few minutes when the car suddenly stopped on the track and stopped moving.

"What's wrong? Is the battery out of power?"

"Impossible, two AA batteries can last for at least half an hour! How could it be out of power in just a few minutes!" Everyone froze, and a staff member immediately went up to take the four-wheel drive in his hands, and repeatedly

I checked, but I can't see why.

"No problem, it's on the metal copper sheet of the switch!" Boss Jia shook his head. "Obviously, the copper sheet you used for the switch is not tough and elastic enough, and the bending arc is not large enough. Over time, plus the track's

An impact will cause poor contact at the switch, and the power will naturally be cut off!"

"This is very important. You must find a way to adjust it for me to ensure that the copper plate at the switch can maintain its elasticity for at least one month. Otherwise, our reputation will be completely ruined!"

"Really, it's really that the copper plate at the switch has a bad contact!" After hearing Boss Jia's words, the inspection staff slightly moved the copper plate, and the car started to fly again.

"Boss! You are so awesome!" This time, all the staff looked at Jia Yapeng like a god. How familiar is his boss with four-wheel drive vehicles? That's why he didn't even touch them.

Check out the problem!

"Tch, when I was playing four-wheel drive, I didn't know how many times I was fooled by this copper switch!" Jia Yapeng shook his head, remembering the story of when he first played four-wheel drive.

At that time, the quality of four-wheel drive vehicles, especially domestic four-wheel drive vehicles, was extremely poor. The problem was mainly concentrated on the copper switch. It was fine at first, but after a short time of use, there would be insufficient elasticity, and then various power outages would occur.

Condition.

At first, Jia Yapeng didn't understand so many problems. He thought it was a broken battery or motor. He didn't know how many batteries had been damaged and how many four-wheel drive vehicles he had replaced. Later, he learned from friends who also participated in the competition that this was the problem.

Problem with switch copper plate.

Those racing-level 4WD vehicles need to go to a specialized Tamiya store to purchase competition-level switch copper sheets for assembly. Otherwise, if the 4WD vehicle stops due to a sudden power outage during the competition, you will lose.
