After the family had lunch in the space, Wen Sitian took Lele back to the bedroom to take a nap, and the three girls and Wenwen also returned to their own rooms.
Xu Jianguo came to the study, made himself a pot of tea, and called Fu Bo over.
"Master!"
"Notify the others and ask them to come back. There's a mission!"
"Okay, do you need weapons?"
Xu Jianguo thought for a moment and said, "Prepare light weapons, equipped with silencers!"
"Yes!" Fu Bo agreed and turned to leave.
After he left, Xu Jianguo came to the studio in the courtyard, took out the drone parts that he had put away before leaving get off work yesterday, neatly stacked them on the operating table, and then began to assemble them.
It took more than half an hour for Xu Jianguo to assemble all the parts into two drones, one large and one small.
The large drone is the size of an A3 paper and is equipped with six rotors. Under full-speed flight conditions, its standby time can reach one hour.
The small drone is only the size of a palm and is equipped with four rotors. Under full-speed flight conditions, its standby time is 25 minutes.
Both drones have a maximum flight radius of five kilometers and are equipped with high-definition night vision cameras and can be loaded with thermal imaging systems.
The maximum take-off weight of a large drone is 15 kilograms, and the maximum flight speed can reach 80 kilometers per hour. The maximum take-off weight of a small drone is 7 kilograms, and the maximum flight speed is 110 kilometers per hour.
Since they are all reconnaissance drones, Xu Jianguo did not equip them with weapon control systems.
However, both drones have good load-bearing capacity. If they are really needed in wartime, they can be equipped with the remote-controlled bombs previously developed by Xu Jianguo to transform the reconnaissance drones into attack drones.
If the manufacturing cost is not taken into account, the combination of drones and remote-controlled bombs will undoubtedly become a nightmare for the enemy in this era.
However, due to the limitations of current manufacturing technology, Xu Jianguo is not planning to release the LCD technology for the time being. He has his own plans, and now is not the right time.
After the two drones were assembled, Xu Jianguo spent some time installing their remote controls. Then, after a simple debugging, he took the drones and walked outside.
After arriving outside the courtyard, Xu Jianguo put the drone on the ground, then climbed onto the roof of his Unimog, which had been struck by lightning in Death Valley and was in a mess, and sat down cross-legged.
Pick up one of the two remote controls, press and hold a red button in the middle for five seconds, and the six rotors on the large drone placed on the ground not far away will spin rapidly, making a barely perceptible buzzing sound.
Immediately afterwards, Xu Jianguo gently pushed the joystick on the left side of the remote control, and the large drone instantly took off from the ground and hovered at a height of 1.5 meters.
Afterwards, Xu Jianguo pushed the right joystick again, and the drone immediately flew forward. When he released the joystick, the drone immediately returned to the hovering state, without any delay at all.
Xu Jianguo placed his thumb on the right joystick and gently turned it in a circle, and the drone followed suit.
After the basic test was completed, Xu Jianguo suddenly pushed the left joystick hard, and the drone climbed vertically rapidly like an onion pulled out of dry land. Then, as he pushed the right joystick forward, the drone flew towards the distance at full speed, completely breaking out the flight speed of 80 kilometers per hour.
Although it flies very fast, the noise it makes is very small, less than 40 decibels, which is completely within the acceptable range even for Xu Jianguo's hearing.
The drone moved forward and soon arrived five kilometers away from the remote control, which was also its maximum flight radius.
Just when the drone was about to exceed its maximum flight radius, it suddenly stopped and hovered quietly hundreds of meters in the air.
At this time, Xu Jianguo jumped off the roof of the RV, and then walked more than ten meters in the direction of the drone. After pushing the right joystick again, the drone hovering there also moved forward another ten meters.
Xu Jianguo nodded in satisfaction, controlled the drone to fly towards him, and then performed various extreme flying maneuvers in the air. In the middle, he recalled the drone, found a 15-kilogram barbell from the gym, and hung it on its body.
Even so, the drone can still maintain full-speed flight status, but the indicator light on the remote control showing the battery status changed from green at the beginning to yellow, and then from yellow to red.
When the red battery indicator light began to flash, the drone in the air in the distance immediately changed direction and flew towards where Xu Jianguo was, then automatically hovered and landed, stopping steadily on the ground one meter in front of Xu Jianguo.
After testing the large drone, Xu Jianguo tested the functions of the small drone again. When all the flight data of the two drones reached the designed theoretical values, he ended the test and took the two drones back.
After bringing the drones back to the study, Xu Jianguo removed the batteries from them and placed them on a special charger to start charging.
After lighting a cigarette for himself, Xu Jianguo looked at the two identical remote controls in his hands, his eyes fixed on their video output ports. With an idea in his mind, he immediately opened the system mall in his mind and bought a Jingzhou brand TV that was suitable for this era. Then he bought a video cable and used the adapter he had made before. He took out the tools to disassemble the TV casing and tinkered with it for a while before connecting the remote control and the TV together.
Xu Jianguo lit another cigarette and drank tea while waiting patiently.
After the indicator light on the charger turned from red to green, he couldn't wait to put the battery back into the small drone, then opened the study door and put the drone in the yard.
As the drone was started, the scene in the yard immediately appeared on the black and white TV screen, which was originally empty. Then the whole screen suddenly rose up, and the full view of the courtyard appeared on the black and white TV.
Then Xu Jianguo controlled the drone to fly around the courtyard, while constantly observing the picture on the black and white TV. Finding that there was no delay or signal interruption, he nodded with satisfaction and put the drone back.
"Everything is ready, it just depends on whether the commander can give us support!" Xu Jianguo muttered to himself.
Unexpectedly, as soon as he finished speaking, he received a message from Du Yu who was watching the house at home.
