At the beginning, Li Shan was still a little confused, but after thinking about it, he suddenly remembered the matter of those bricks, so he took out a sad look and said: "Hey, don't mention it, you were fooled, it is not a cultural relic, it is all some modern counterfeit imitations." After saying this, he pushed open the door and walked out, and my mother was at a loss....

Since the drone is still being transformed by Lao Gu, for Li Shan, who is used to practicing drones every day, he feels a little uncomfortable.

Now he is more and more inseparable from the drone, the perfect combination of the drone and the laser, so that he is like a tiger wings, this is Li Shan's confidence in doing everything, but also the biggest reliance in his heart, so, he attaches great importance to this, in addition to the business trip for a few days, at home, as long as he is free, he repeatedly practices flying skills, and gradually forms a habit, more or less psychological dependence, and now there is no control of the drone for many days, it makes him feel very uncomfortable.

No, don't you still have two drones on hand, these two drones were obtained from the two guys who attacked you last time in the Qinling Mountains.

Because human life is involved here, I am worried that once I am recognized by others after use, I can't tell clearly, not to mention that the two drones also carry devices that can fire bullets, which is unexplainable on any occasion. If those two guys use it to do some illegal things, as long as they check the bullets, everything will be clear, and maybe some big case will be led to it, in that case, wouldn't he have to bear the blame for those two guys. With this layer of concerns, Li Shan has been keeping it a secret and hiding all these two drones.

Now if you want to use them, you have to consider the feasibility.

As long as you don't use it blatantly in broad daylight, you don't need to worry about exposure. It's a safe way to use it as a backup, and if something happens in the future, you can also respond to emergencies. In addition, he still doesn't know what other functions these two drones have, so it's better to find an opportunity to give it a try.

Thinking of this, Li Shan turned over the two drones hidden at home, these two drones are biaxial, that is, the kind with two propellers, the whole is black and gray, the most striking thing is the device that can shoot bullets, Li Shan doesn't know what this thing is specifically called, and now he has to name it a bullet launcher first. In addition to knowing what functions they have on them, Li Shan is not clear.

First of all, we should understand how far these two drones can fly at most, Li Shan has no experience in this area, he can only understand it through test flights, and this kind of flight can only be carried out at night.

So, on a moonlit night with sparse stars, Li Shan found a place near his home where no one was around and began to test fly. Nowadays, people often fly drones at night, so his test flight did not attract much attention from others.

In order not to cause unnecessary trouble, he also deliberately removed the bullet launcher, so that even if it was seen, it was no different from an ordinary drone.

When the initial test flight was carried out, it was found that the flight distance of this drone was only a little more than 2 kilometers, which made Li Shan, who was looking forward to it, very disappointed. At first, he thought that with the ability of those two guys, its flight distance would not be closer than his own, and his drone could at least fly to about 4-5 kilometers, but he didn't expect it to be shorter than the range of his own drone.

At that time, when he was flying in the Qinling Mountains, there was nothing to cover, and Li Shan clearly remembered that his drone flew at least 4 kilometers at that time, and it was there that one of the guys' drone was found.

No, there seems to be a bit of a problem here, at that time I was not too far away from the two guys, and at that time my drone flew out about 4.5 kilometers, that is to say, the other party's drone must have flown the same distance, and now the range of the test drone is less than 2 kilometers, there must be something wrong here.

Later, Li Shan carefully studied the drone, and he believed that the relevant secrets should be in the remote control. He turned on the LCD monitor on the remote control, and called up all the menus, looked at each item carefully, when he saw the GPS option on the menu, he couldn't help but move in his heart, he called up this option, clicked in and found that there were only two options inside, which were on and off, and at this time this option was in the state of off, so he adjusted this option to the ON position, and then pressed the confirm button.

Li Shan restarted the test flight, watching the flying drone gradually disappear into the distance, the data of the drone's flight on the remote control monitoring screen is constantly beating, the main screen on the monitoring screen shows the perspective captured by the camera on the drone, and a small screen appears on the screen, showing an electronic map, a small red dot that keeps flashing along the map, this should be the location of the drone.

Due to the city's no-fly restrictions, Li Shan only dared to fly to some open areas to the north, at this time his flight altitude was about 300 meters, and he could see the ground lights sparkling, winding into the distance.

Li Shan didn't have time to enjoy the beautiful night view of the city for a while, and what he was most concerned about now was how far the drone could fly.

Soon the drone flew 2 kilometers, but there was no alarm signal like the previous time. When the drone flew another 4 kilometers, Li Shan's original heart finally relaxed.

But when the drone just flew five kilometers away, suddenly the battery on the monitor began to alarm, indicating that the power was already insufficient, and Li Shan had no choice but to retract the drone.

Through the test, Li Shan knew that this drone can be controlled by satellite positioning, that is to say, as long as there is a satellite signal, it can fly wherever it wants, as for the specific ability to fly and multi-transport, it all depends on the power of the battery.

Li Shan immediately thought of the battery he had modified. The original ordinary dry battery, since the addition of mysterious pulverized coal, so far there has been no lack of power, if the modified battery is applied to the drone, under the guidance of satellite signals, you can realize the wish to fly anywhere.

Thinking that one day there is no need to run to a specific occasion to control the drone, and he can lie on the bed to complete these controls, just as easy as lying on the bed and looking at his mobile phone, makes Li Shan very excited.

With the deepening of his understanding of drones, Li Shan found that in addition to being proficient in drone control, he also had to have a certain understanding of some basic knowledge of drones. Through continuous learning, he found a problem when he tested the two UAVs, which cannot be said to be a problem, mainly related to the transmission of UAV images.

Generally, the transmission distance of UAVs is only two to three kilometers, and the performance is only six or seven kilometers, and the images transmitted back by the two UAVs at hand are relatively stable, although there are also some stuck phenomena.

This made Li Shan curious, so he disassembled the drone and found something similar to a mobile phone card stuck in one of the parts.

Li Shan took it off and looked like a mobile phone card, so he tried to install it on his mobile phone, and found that it could still be used, and after checking the balance, there were more than 17,600 yuan in it.

What's going on?

Li Shan fell into deep thought for a while, why did this drone integrate the functions of a mobile phone into the drone.

This involved communication technology, and in the following days, Li Shan searched for a large amount of information on the Internet, but did not find any introduction to this aspect.

Looking at the phone card in his hand and some electronic components related to it, Li Shan's eyes were black, and he couldn't understand anything.

He can't ask anyone about all this, so he can only rely on himself to analyze and judge.

Through the information found on the Internet these days, he analyzed that the farthest possible real-time image transmission of ordinary UAVs is 8 kilometers, if you want to improve the distance of image transmission, it is necessary to increase the power of related equipment, and the current UAV flight distance is also five or six kilometers, simply improving the power of image transmission equipment does not have much practical significance.

If some functions of the mobile phone are integrated into the drone, in this way, if the image transmission distance of the drone itself is exceeded, the mobile phone mode will be activated, as long as there is a mobile phone signal, it can be like a mobile phone video, to achieve instant image transmission.

This guy had a good idea, and it was successfully applied in practice. This mobile phone transmission image mode is likely to be prepared by the two guys for long-distance flight of the drone in the future, so that when the drone exceeds its own image transmission distance, it can also realize the transmission of images through this mode.

Those two guys were so deliberate about the design, they definitely didn't want to shoot any scenic films.

Thinking of that shooting device, with the style of those two guys, eighty percent of them are going to do something unseemly.

If they can use it, why can't they use it themselves?

Li Shan turned over those bullets again, and he currently has 56 bullets, although he is not very clear about the types of these bullets, it is not a problem to judge that these are rifle bullets.

Generally, the effective distance of rifle bullets is about 300-400 meters, which means that the straight-line strike distance of this drone is about 300-400 meters.

And if you want to master the shooting technology of these drones, you have to practice constantly.

Those two guys will not appear in the remote place in the Qinling Mountains for no reason, are they also conducting some tests like themselves, and at present, it seems that the most likely thing is to practice shooting skills.

To carry out this kind of live shooting, the urban area is definitely not good, and at present, only the Qinling Mountains are the most suitable for the surrounding area, but Li Shan still has some doubts about shooting training in the Qinling Mountains, because everything that happened in the mountains several times made Li Shan feel that Qinling Mountain is not compatible with himself.

It would be ideal if you could control the drone at home to practice in the Qinling Mountains.

Li Shan pondered the possibility of whether this could be realized. My home is too far away from the Qinling Mountains, and if you want the drone to fly there, you must install a battery modified by mysterious pulverized coal on the drone, so as to make this idea possible.

If you want to install the modified battery on the drone, you will first face the problem of voltage regulation, which requires the addition of a transformer to avoid damage to the motor caused by excessive battery voltage.

I don't know anything about this kind of modification of electrical components, but this drone can't be transformed by Lao Gu, which makes Li Shan a little difficult.
