The next morning.

When Tang Rui woke up from the sofa, the sun had already climbed overhead.

He picked up his phone and looked at it.

It's already half past ten in the morning.

"Suck!"

Tang Rui, who got up from the sofa, directly gasped.

It was a tiring day yesterday.

Thinking about the drone at night, I fell asleep from the soft sofa before I knew it.

As a result, now he is sore all over.

Especially the waist, the moment you stand up, it's called a sourness.

Tang Rui stood and moved his body, and after feeling the soreness in his cervical spine and waist, it hurt very much.

Making model airplanes is not a physical job.

But to concentrate all the time and bend your head down at all times, it hurts the cervical spine, spine and lower back a lot.

Not to mention the high-intensity, long hours of work like yesterday.

If you do this often, something will happen sooner or later.

"If only I could add some to my body."

At this moment, he hopes that his plug-in can be like dark blue, which can add some points to his body.

Wait a minute......

Do you want to make a massager and try to upgrade it?

Never mind.

More on that later.

I went to eat first, starved to death.

It took five minutes to wash and change clothes.

Tang Rui took his mobile phone and left the house.

The breakfast shop is very close to his house, and there are several outside the community.

Come to the familiar breakfast shop.

As usual, I ordered a bowl of porridge, two steamed buns, a plate of pickles and a tea egg.

While eating, he opened the APP of Xiaopo Station and clicked on the backstage.

"Goo-goo-goo......"

"What about the UP Lord? didn't quit the Internet café, who said that it would be changed every day for three months in a row, it's only been less than a month, why is it broken? ”

"Melon seed snacks are ready, waiting for the UP main live broadcast to wash your hair upside down."

Seeing these messages, Tang Rui was very painful.

He did forget to update the video yesterday, and he also forgot about the fact that he had bragged about changing it every day for three months in a row.

It's embarrassing right now.

If you brag about it, you will definitely not be able to fulfill your promises.

Is it really going to be a live handstand to wash your hair?

When he thought of the scene of social death, the tea eggs in his mouth were not fragrant.

Put down your phone.

Leave that alone.

It's a big deal after a while, wait for the drone to be done, and then start a live broadcast to fulfill the promise.

After breakfast.

Tang Rui returned home and began to rummage through boxes and cabinets to find things.

Yesterday he fell asleep while thinking about the problem.

But there are also some ideas.

The drone thing is not something that can be done by patting the head, but it must be combined with reality.

Even if he has a golden finger, he can't be divorced from reality.

What is this reality?

The reality is.

He has no money.

A real drone with all sorts of equipment inside.

For example, high-definition white light cameras, infrared thermal imaging cameras, ultraviolet thermal imaging cameras, synthetic aperture radar, lidar, and multispectral cameras.

These optoelectronic devices are not all equipped, but they must also have the most basic ones.

Without optical cameras and radar, what is it called a drone.

In addition, the entire avionics system also needs to be equipped with many modules such as on-board computers, communications, radar, navigation, fire control, and flight control.

Not to mention the engine, which is the hardest thing to do.

If only he didn't have a system panel.

No matter how much money he is given, he will not be able to make a real drone by himself.

But with the system panel it's different.

He definitely didn't have the money to buy the equipment and difficulties listed above, but he could upgrade and strengthen them through the system panel.

However, the system panel can upgrade and enhance items, but it also needs to be something.

That's why after he came back, he began to rummage through boxes and cabinets to find replacements for these devices.

In the years of college, he tinkered with a lot of things.

In the model aircraft club, there are all kinds of cattle people, and everyone has no money.

If you need accessories, you can only do it yourself.

After all, the school has a laboratory, and the equipment in it can be used, and even some materials can be rubbed.

So in the past few years, he has also done a lot of good things.

Crash!

He pulled out two large boxes from the cabinet.

Then from a box, take out an A4 paper-sized circuit board.

On this board, there are also a lot of follower wires, and at the other end of the wire are the transmitter and receiver.

"Finally turned it out."

Tang Rui blew the dust on the circuit board, and his face was full of smiles.

The full name of this thing is called, S-band micropower phased array radar.

This radar belongs to the FMCW (Frequency Modulated Continuous Wave) technology radar.

Don't look good, but you can't buy this kind of thing on the market.

The reason why he was able to get this thing was when he was in the university model airplane club, he borrowed it from a graduate student.

Later, the senior brother was poured a meal of wine by him, and when he was drunk and bragged, he gave him this thing.

That senior brother didn't regret it, he didn't know.

Anyway, since that time, the senior brother has never drunk with him again.

Now that senior brother is engaged in research and development in CETC, and his technical level is quite awesome.

Far from it.

The phased array radar is done, and the rest of the equipment is even better.

The engine was dismantled directly from his baby model airplane.

These are two real turbojet engines.

Standard thrust 80N (8 kg), speed 5W-18W, fuel consumption 200 g/min.

It's easy to say that the body is made of junk materials first, and then add some upgrades.

Optical equipment also uses this method, first install the camera, and then add some upgrades.

Equipment is nothing.

The real trouble is the integration of the avionics system.

For others, putting these patchwork together is as difficult as redesigning a system.

But for the system panel, it's a reinforcement thing.

Tang Rui brought the model aircraft that had been strengthened last night to the workbench.

[Item: Exquisite fixed-wing model airplane +3]

[Experience: 363/?] (Non-upgradeable)】

[Strengthen: Body]

[Source point: 0]

After a buff, a list of properties appears on the panel.

However, the experience line is still non-upgradeable.

Click!

Tang Rui did not hesitate to dismantle this exquisite model airplane.

Battery, motherboard, motor, turbofan, cab model.

Except for the entire fuselage of the model airplane, all other parts were dismantled.

Then he violently enlarged the engine vents at the rear of the fuselage and stuffed two turbojet engines into them.

It's really hard to shoehorn in.

The body is deformed.

But it's all a minor problem, and he doesn't think he sees it.

Boom.

The wires attached to the radar motherboard were torn off, and he stuffed the transmitter, receiver and modem into the airframe.

Then these wires are casually soldered to the edge of the ECU motherboard, and they are not connected to the circuit.

He did it on purpose.

Once connected, his ECU will be useless, and even the turbojet engine will not be able to start.

At the moment, he doesn't need this drone to have any functions, the only requirement is to be able to go to the sky.

So the other components are not important, the most important thing is the flight control and the engine.

After loading these things, there is almost no room in the body.

Tang Rui looked at it, adjusted it slightly, moved out some empty spaces, and stuffed the battery plug and the flight control motherboard into it.

At this moment, there is no place inside the body.

In the case of the camera, it can only be tucked into the driver's cab, and the lens can only be pointed at the sky.

It can't be said that it is useless, only that it is useless at all.

"That's it."

Tang Rui snapped his fingers, very satisfied with his masterpiece.

But at this moment.

The panel on the model airplane attracted him.
