"Boss, look, all the parts are made according to the requirements of the design drawing!" In a small workshop of the Daqian Food Factory, several people in work clothes surrounded Jia Yapeng, while Jia Yapeng sat on a workbench, looking at various parts scattered on a tabletop in front of him.

"Haha, I haven't played with this thing in at least ten years, and it's really nostalgic to see it!" 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 4x4 when you were in your 10s? An old man who was over half a hundred years old on the side said with some doubts, "But it's not right, the four-wheel drive car was invented in Fusang in 83 years, where did you play with the four-wheel drive car ten years ago?" Could it be the R&D version of Tamiya? ”

"Actually, it happened seven or eight years ago, when Tamiya was just going on sale for a 4WD, my dad brought one from Fuso to make a toy for me, and it was my best toy!" Jia Yapeng told lies seriously.

"Come on, let's see if my level of assembly at the competition level back then is still there!" Jia Yapeng smiled slightly, and the expected chassis instantly appeared in Jia Yapeng's hands, and then gears, shafts, motors, motor covers, guide wheels, gaskets, rubber guide rings, phoenix tail wings, switches, axles, hubs, open tires, and finally the car cover and jet 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 staff who built this model car were dumbfounded.

Although this model car is made by them by hand, step by step, and each part is polished by them, if they can assemble it by hand, it is impossible to assemble it without more than ten minutes.

As a result, Jia Yapeng took more than 4 minutes at most to assemble a four-wheel drive car, which is simply a miracle, could it be that Jia Yapeng has assembled the four-wheel drive car countless times?

"Don't be surprised, in fact, in Fuso, there is already a very systematic four-wheel drive competition, one of which is the four-wheel drive vehicle assembly, the competition is who can assemble a standard four-wheel drive vehicle with the fastest speed!"

"I haven't built a four-wheel drive for a long time, the speed has slowed down a lot, I was at my peak and was able to assemble a four-wheel drive car in about three minutes, and the record on the Fuso side is that a player is in 09...... Created in '89, it took only 1 minute and 02 seconds to assemble a complete 4WD vehicle, including the time to put the sticker on the hood! ”

"So put away your shocked expressions, or if you see those record holders in the future, won't your jaw be gone!" Jia Yapeng laughed and said, and the staff laughed.

"Come on, let me try it, how fast this four-wheel drive is!" Jia Yapeng flicked the switch, and a loud engine sound began to roar, and the four wheels of the four-wheel drive began to rotate at a very fast speed.

"This motor doesn't work!" Jia Yapeng listened to the voice, then shook his head and said, "The number of coil materials of the motor is too small, and if the speed of such a motor can't go up, at least about one-third more!" ”

"There is also a problem with the occlusion between the gears, the noise is too loud, and it won't take long for such gears to break!"

"Wait...... Why does it smell burnt? Did I forget to apply lube just now? Or are you not providing lubricants at all? ”

"This can't be done, in the future, a small tube of lubricating oil must be put into the product, and the occlusion of each gear must be coated with lubricating oil, otherwise the life of the car will not be long!"

“……”

In less than a dozen seconds, just by listening to the sound and smelling the smell, Jia Yapeng pointed out more than a dozen defects in one breath, which made these staff members both ashamed and shocked.

I am ashamed that I think that the foolproof experimental product still has so many defects, and the shock is how familiar my boss is with four-wheel drive vehicles, and he is so much more powerful than his own R&D personnel, which is too bullish!

"You forgot 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, and the boss's ability is naturally not comparable to you! The old man on the side scolded.

"Okay Lao Li, I'm a little embarrassed for what you bragged, I just used to play more!" Jia Yapeng laughed, "By the way, is there a runway?" Then this car runs and sees! ”

"Yes, it's been ready for a long time!" Lao Li took Jia Yapeng to a clearing lot, on which a winding circular track had been set up.

"You're actually using iron plates to build the track?" Seeing the material of this track, Jia Yapeng exclaimed.

"No way, we also know that the track with plastic is cheaper, but the mold of the plastic track is more troublesome, and it can't be made in a short time, so we temporarily weld one with an iron plate!" Lao Li explained.

"Yes, it's the first time I've raced on a tin track, hahaha!" Jia Yapeng laughed, put the car on it, and the car immediately began to run wildly on the track.

"It worked! We did it! Seeing the car running so happily, the surrounding staff immediately cheered. You know, they have been working for about three months to make this little four-wheel drive vehicle, which is really hard.

But the cheers of these staff members did not last for a few minutes, and the car suddenly stopped on the track and did not move.

"What's wrong? Is it out of power? ”

"No way, two No. 5 batteries can run for at least half an hour! It's only been a few minutes, how can it be that the power is out! Everyone stiffened, and a staff member immediately went up to take the four-wheel drive car into his hand, and checked it repeatedly, but he couldn't see the reason.

"No problem, on the metal copper sheet of the switch!" Boss Jia shook his head, "Obviously, the toughness and elasticity of the switch copper sheet you use are not enough, and the curved arc is not large enough. ”

"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 the elasticity for at least a month, otherwise our reputation will be ruined!"

"Really, it's really the copper plate at the switch that is in poor contact!" Hearing Boss Jia's words, the inspection staff fluctuated the copper sheet slightly, and the car flew up again.

"Boss! You're just amazing! This time, all the staff looked at Jia Yapeng like a god, how familiar his boss was with the four-wheel drive, so he would check the problem without even touching it!

"Cut, when Lao Tzu played four-wheel drive, I don't know how many times I was pitted by this switch copper sheet!" Jia Yapeng shook his head, remembering the story of when he first played with four-wheel drives.

At that time, the quality of four-wheel drive vehicles, especially domestic four-wheel drive vehicles, was extremely poor, and the problem was mainly focused on the copper sheet of the switch.

At first, Jia Yapeng didn't know so many problems, and thought that the battery or motor was broken, I don't know how many batteries were pitted and how many four-wheel drive vehicles were replaced, and later learned from the mouths of friends who also participated in the competition that this was a problem with the copper switch.

Those racing-level 4WD cars need to go to a special Tamiya store and buy competition-level switch copper sheets to assemble, otherwise if the 4WD stops because of a sudden power outage during the race, it will be lost!

In a few seconds, you can be left behind by several laps.

These experiences are all the experiences that Jia Yapeng gave in his last life!
