In order to congratulate Brother Dabing on becoming the master of this book, there will be a third update today. Fatty said it will definitely be an update if he added it, and do what he said!

.........

When the dragon tower came down, both of them still felt a little unfulfilled. The winter melon completely let go of the knot and was as happy as a little butterfly. She rarely went out to play. This time she went to the Ice City with a mission. Now she has taken the burden and is naturally happy.

Liu Meng also felt a sudden enlightenment. He was infected by the joyful spirit of winter melon and was also happy. The two ran like children. Liu Meng was carrying the winter melon suitcase in his hand, and he was not as clever as winter melon.

Not far from the dragon tower, several children were playing, running while running.

The winter melon stopped and stared at the sky in a daze.

"What's wrong?" Liu Meng followed and asked.

"Look, the small plane looks so fun!" The winter melon pointed at the little thing flying in the sky.

Liu Meng looked in the direction of her finger. Isn't that right? Several small planes were hovering in the sky, and several children were controlling the remotely, running while controlling. One child was very agile. After the small plane fell freely, he suddenly increased his horsepower. The small plane actually made a side-flying and rolling move. The other children couldn't help but cheer.

You can see at a glance that these small aircraft were made by themselves, with very good communication effects. In addition, third-order PI, double-layer PID, fuzzy recognition and other control technologies have been added to the control. The control recognition between the small aircraft and the remote control is very robust.

However, Liu Meng was surprised that this child was able to make a rollover.

The winter melon is also staring at it like a child, with longing in her eyes. This kind of toy is really rare. I have never seen the children playing so smoothly.

Liu Meng nodded and smiled, "Isn't there anyone selling it in front? I'll buy one for you to play with."

The eyes of the winter melon shone brightly, and then he felt a little embarrassed, "I'm so old, it's not good to play with this."

"What's the matter? There is also the old boy who said it, let alone you are so young and look like a girl." As he said that, he was afraid that she would be embarrassed, he took her hand and walked forward.

Donggua was very embarrassed to be pulled by someone, and she wanted to break free but was embarrassed to try hard. Seeing Liu Mengxing hurried forward, she didn't deliberately take advantage of her, so she had to acquiesce to such a move.

Liu Meng is familiar with this stall selling toys. Last time he asked him to take him to the toy mall. The young man was still impressed by Liu Meng when he saw him and nodded with a smile.

When he walked in, he saw that the young man was indeed selling small planes. Of course the car was still there. Liu Meng smiled and said, "I haven't seen you for a few days, and you're selling small planes again. What's the market?"

The young man smiled honestly and said, "It's very popular. Although the price is nearly ten times more expensive than a car, the child especially likes to play. When he sees his classmates playing, he insists on buying it for him. I'm planning to stop entering the car anymore, and the profit is too thin."

Liu Meng was a little surprised. He expected that the small airplane would be very popular, but the price was too expensive, which should affect sales. Unexpectedly, it was so popular that a street stall sales actually exceeded that of a small car that was ten times cheaper.

Thinking of this, I couldn't help feeling bitter, but then I became cruel and thought coldly, Huang Sheng, if you gave me that 5,000 yuan, although I was unwilling to accept it, I would also swallow this glass of bitter wine myself. Now, you can work for me first and sell more goods.

The reason why small aircraft can be sold so popular is because control algorithms and communications do surpass electronic toy products of the same period. Many children have made a variety of tricks after buying them, just like the overturned ones I saw just now, it suddenly formed a reputation effect and became a trend for children toys.

"Hehe, I tell you, a small plane sells a profit of 25 yuan. If you sell ten planes a day, it will cost 250 yuan. It's very good. You can also consider adding a batch of goods to the township and try it." The young man smiled and whispered.

Seeing that the two seemed to be familiar with each other, Donggua couldn't help but look at Sanpang and then at the young man setting up a stall.

"Well, I bought it for someone too. Let's see if the results are effective. Will I also get the wholesale goods?"

"Then you have to hurry up. I heard that only Boss Huang can do it now. The toy mall is almost out of stock. I'm going to prepare more goods later." The young man said honestly, handed over a small plane and said, "You bought it for your child, too. The child loves to play with this, which is very high-tech."

Liu Meng looked at the shy winter melon on the side and laughed: "That's it, I'm so annoyed that I have to come out and buy it for her. Well, I bought it for my niece."

"I only charge you a cost price." Liu Meng gave him two hundred yuan. The young man was confused for a while, but he still found another 30 yuan for Liu Meng, so he would not make Liu Meng's money.

Liu Meng refused to accept it after he urged him, but the young man refused to accept it. Liu Meng had no choice but to accept it.

"You first arrived in the Ice City, but you didn't fulfill your friendship with the landlords. You even ate two meals. You just happened to give you this gift, so let me show you." The two walked out for a while, and Liu Meng handed over the plane.

The winter melon was curiously opened, and couldn't help but look at Liu Meng again, "Why do you even know the toys sold on the street stall?"

Liu Meng smiled strangely and suddenly said, "If I say that this small plane was developed by me, do you believe it?"

Donggua giggled, but she still said seriously: "I believe it! I think that any strange thing can happen to you now."

"Hurry and try flying, my little niece!" Liu Meng said with a smile.

When Donggua heard him talk about this, she thought of taking advantage of him in front of the young man just now, and then whistled her little pink fist, but it fell very lightly on her body, just like the wind blowing on the willow branches. "Hate, take advantage of me, I am two years older than you!"

"Okay, hurry up and feel it. The sense of manipulation is really good!" Liu Meng quickly begs for mercy.

The winter melon was quickly installed on the battery and started playing. At first, it was not good at the key points and was always not well controlled. However, the small plane did not fall down by itself, and the blades would automatically rotate to increase the downward resistance to facilitate the operator's reaction.

Liu Meng looked at it and was very satisfied. This was the fuzzy control added to it. After the production was completed, he didn't have time to test the flight. This was the first time he really saw the effect.

Donggua does have a pair of skilled hands, she is good at cooking, and she is also very adept at playing with a small plane. She quickly mastered the control points and flew into the air ten meters. She accidentally made Marseille spiraling movements. The control was very smooth, and the more you played, the more you loved it.

Looking at it, Liu Meng finally understood why sales were so popular, and the addition of multiple controls made it easier to remotely control small aircraft. This is the main reason.

The winter melon was having a lot of fun, just like the child just now, running while controlling the remote control.

"I look cold and arrogant all day long, but I didn't expect that there was a naughty girl living in my heart. It was really interesting." Liu Meng was happy to see it, and sighed in his heart.

The winter melon was sweating profusely before stopping, her face flushed, and she was very excited, "Sanpang, this is really fun, you can try it too. I have learned several flying stunts, and it's so good to play."

Liu Meng also wanted to try out the performance, and did not postpone it now. He put the suitcase aside and tried to play. He played mainly because of the maneuverability of the small aircraft, such as the maximum height that the small aircraft can rise, the fastest speed of forwarding, and the range of flexible communication distance between the remote control and the small aircraft.

Donggua followed behind her suitcase, curled her lips, thinking to herself, saying that I am your niece, seeing that you are more enjoyable than me, you are my nephew! Thinking of this, I felt that I had taken advantage of Sanfat, and I couldn't help laughing.

Liu Meng kept testing, and the more he tried, the more he tried, it was equivalent to actually testing the running code inside, naturally simulating different working conditions. He also had a habit of being extremely focused once he was involved. This was the case when he was typing with all his strength, developing small planes, and solving mathematical problems.

Once you do something, you will forget everything around you and become addicted to it.

Donggua followed and saw Sanpang actually heading to the main road, and a very fast car roared towards her. Without thinking, she threw down her suitcase and rushed towards Sanpang, trying to knock him away.
