The heated discussion about Wang Hao continued in the next few days, but Wang Hao didn't care, locked himself in the room, and frantically studied the optimization of his little dragon.

He handed over the signal transmitter he made to Fang Bing, and after the other party learned the function, he couldn't put down the signal receiver, and after experiencing the first live broadcast, Fang Bing knew that there were too many problems to consider.

The live broadcast signal of the mobile phone is a big problem, because there are no residents in the deep mountains, and no signal towers have been built, resulting in a very unsmooth live broadcast in the deep mountains.

In the next few live broadcasts, because of the signal amplifier, Fang Bing's previously selected locations all overturned the re-election and chose to go deeper into the mountains and forests.

Fang Bing is frantically practicing his body and absorbing the knowledge of the wild, and the place he chooses to broadcast live is becoming more and more mountainous, and the danger is still not small, although the knowledge that Fang Bing has can deal with it in these deep mountains, but Wang Hao, who is not very relieved, specially made some self-defense things for him, it must be alone in the deep mountains, and the necessary protection measures must still be there.

The drone was also sold in the live broadcast of Fang Bing's fire, and as soon as it was sold, Fang Bing's parents, as well as Zhang Xin and Zhang Nan, sold out the drones assembled by the four people.

The Tianbing UAV manufacturing company, which had been registered before, began to really recruit people from the outside world, originally Fang's father and others planned to take Haobing UAV Manufacturing Company, but Wang Hao looked at this name and refused without thinking about it, and named it Tianbing UAV.

Fang Bing's live broadcast made the drone out of stock, and the drone assembled by only four people was in short supply at all, so it could only expand production capacity again.

And the new batch of drone materials was also transported again with Fang's father's order.

Wang Hao also asked Fang's father to order some materials, in order to study the second type of solar drone, this research did not take much time on him, he did not need to think about many things, just spent some time on the structure and the selection of materials.

Whether it's solar charging panels or other materials, they are all custom-made accessories, and all he needs to think about is how to reduce the weight of the aircraft to increase the duration of the flight, and the stability of the architecture.

The most important central control program of the drone is also ready-made and can be used with a single change, so he quickly came up with such a test model of the second generation of Tianbing UAV.

Now Wang Hao is in the factory rented by Fang's father, looking at the three drones flying in the air, Zhang Xin walked over from the side, and said with a little surprise on his face,

"Brother, it's been three hours. ”

"There is a drone that is not flying very steadily, and it is estimated that it is about to fall. Wang Hao seemed to regret that he only had such a short time, shook his head and said, this is the second type of heavenly soldier. Solar energy as an energy source of drones, at this time more than three hours have passed since his test, a drone finally appeared a little unstable.

As soon as Wang Hao's words were spoken, the drone seemed to have received an order, and slowly fell to the ground, and the other two flew in the air, and after a while, another drone shook a little and fell, while the other continued to fly in the air.

"It's a pity to protect the battery, otherwise it would have been a little longer. A trace of regret flashed in Wang Hao's eyes, but if other drone manufacturers heard his words, they would probably vomit three liters of blood, and their drones were still worried about lasting an hour, but he now made a four-hour drone.

Other drone manufacturers have not thought about extending the flight time of drones through solar energy, but if the solar energy is charged, the voltage is unstable, which will greatly reduce the life of the battery.

But for Wang Hao, he made a voltage controller to control the output power of the solar panel, but he only needs to choose some lighter materials to make drones, resulting in the weight of the drone is too light, and in the case of strong winds, there will be a swinging situation, until he wrote a level adjustment program in the central control program is slightly better, but there will still be some shaking, this is also no way.

Light has the advantage of being light, it can fly longer, and heavy has the advantage of being heavy, but it makes the shooting more stable, so he plans to divide the Tianbing II into two products, one is a light drone that can shoot for a long time, and the duration of the heavy can only last for three hours at most.

However, the light one can last for four to five hours, and Wang Hao already has a stereotyped idea in his heart.

Now there are not many people in the factory, only about a dozen people, but the benefits of drones are still very considerable.

Now they have no sales channels and can only sell through the Internet, and the object of sales is naturally the audience in the live broadcast room of Fang Bing, as for the profit, the procurement cost of the molded accessories is indeed high, but the use performance is good, and the profit is considerable.

Now the sales object is only the audience in Fang Bing's live broadcast room, and only these viewers have seen the strength of the drone with their own eyes, so they have the idea of wanting to buy one, because Fang Bing generally does not only take a brand new drone out at this time, but goes out with two drones.

The audience in the live broadcast room looked at the two drones, and after Wang Hao modified the drone APP, another function was added, that is, to manage multiple drones, and they could freely switch perspectives.

The two drones automatically circled around the soldiers like magic weapons, and it was really itchy to look at some rich local tyrants, and the rich even bought three to five units.

There are also some anchors who saw Fang Bing's live broadcast, and they have also purchased some drones, the function of this drone is very fresh, and it can automatically avoid obstacles without human control.

This made many anchors happy to see the hunt, but after they went to the overseas shopping website that Fang Bing said, they found that the eye-catching wordless at this time was so dazzling.

This Wang Hao and Fang's father didn't have much to do, because their starting funds were very limited, at that time, 500,000 yuan was used to rent this factory, and more than 1 million yuan was used to purchase materials, so it can be said that there was no spare money at all.

The cost price of a material accessory is about two thousand five, and the price of the Tianbing type one is very civilian, about four thousand, after all, the Tianbing drone is not better than other drones, not to mention, there is no money to advertise, if it is too expensive, it is not conducive to opening the market in the early stage.

Compared with other drones with tens of thousands of movements, this price is indeed very close to the people, and the performance is very superior.
