Erdan smiled foolishly and knew that it was not so easy for him to be with Weiwei. The Long March of thousands of miles is all made by people. Climbing snow-capped mountains and crossing grasslands. No matter how difficult the process is or how bumpy the road is, please believe that Li Erdan will never retreat.

"Let's just do a simpler one first, spiral landing." Erdan said, and at this time the helicopter rose to an altitude of nearly 300 meters.

If the helicopter flight stunts are the most difficult to achieve five stars, then "spiral lifting" will take up three stars, which means it is a bit difficult, but not too great. Otherwise, how could Erdan say it is simple? Cai Xiaolin can also play with this "simple" action, so he did not express his opinion. Spiral lifting, as the name suggests, means that the helicopter is hovering up and down, and the path can be compared to springs or threads.

Erdan started to move as he said that, controlling the aileron and lifting rocker with one hand, controlling the total pitch rod with the other hand, and controlling the tail rudder pedal with both feet to change the tail rotor pitch. The helicopter's rotation and landing is mainly divided into two actions. One is to descend. By controlling the lift, the propeller rotates slowly, and the lift will naturally drop when the lift is reduced; the other is to rotate, control the tail rotor, so that the lateral force generated by the rotation of the tail rotor is unbalanced and the torque generated by the top propeller is unbalanced. When the size of the two is different, the helicopter can rotate forward and reverse. If the helicopter's fuselage is inclined at an angle, it can also spiral landing while flying.

With Erdan's movement, the helicopter really turned, and first kept the height unchanged and the fuselage rotated clockwise. When the tail rotor rotated, the helicopter became faster. From a distance, the helicopter was like a dragonfly spinning in place. Of course, no matter how fast the helicopter rotated, it was impossible to have a motivation to rotate quickly, and even the ballet dancer's rotation was not as good as that. It was just that.

"Li Erdan, can you hurry up? Oh my God, it's so fun. I decided that I want to learn to drive a helicopter. Li Erdan, you have to teach me." Xiaoxiao shouted exaggeratedly, very excited.

"I'll teach you if you ask my brother-in-law." Erdan.

"If you don't shout, you won't shout if you beat me to death." Xiaoxiao.

"If you don't ask me, I won't teach you." Erdan.

Cai Xiaolin suddenly interrupted, "Xiaoxiao, Brother Li doesn't teach you, Brother Cai can teach you."

Xiaoxiao frowned, "You won't let me be your girlfriend to teach me, right?"

"Oh, you guessed it all." Cai Xiaolin.

"Hmph, there's no way. If you don't teach me, I'll find a professional master. Anyway, there are so many institutions that train helicopters now." Xiaoxiao.

Weiwei became much quieter, holding the seat belt tightly with both hands, and turning the body made her dizzy, and she also said to Erdan, "Brother Erdan, if you turn again, I will be going to be airsick."

It's a little bit of a planesick, that's all!

"If you turn the helicopter in reverse, you won't be dizzy. This is called positive and negative elimination." Erdan said, and his hands were rushing again. Soon the helicopter that rotated clockwise turned counterclockwise. When the lift of the propeller was reduced a little, the helicopter turned counterclockwise and the degree remained at one meter per second. It may be that the helicopter's mass was not yet strong and the fuselage was a little vibrating. After all, civilian helicopters cannot be compared with military ones. When Erdan learned to drive a "direct" armed helicopter, he was roaring up and down, and the rotation and landing degree was even three meters per second.

When the helicopter descended to ten meters from the water surface, Erdan asked the helicopter to climb up and prepare to perform the second program, volleying somersaults, with five stars in difficulty, which means it is very difficult.

Cai Xiaolin couldn't do this action, but the technology was one aspect. The more the reason was that the helicopter was not good, so he was unwilling to let Erdan do it, so he said, "Brother Li, let's forget about this action! My helicopter couldn't do this action, and the quality was not good. It accidentally fell into the sea. It was not a joke."

Cai Xiaolin's concerns are normal. According to the saying, if you want to complete this action, you cannot do it by a special pilot. It is rumored that only a few helicopters and a very small number of pilots in the world can complete this action.

Erdan still looked smiling and was a little addicted again, "It's okay, I'll compensate you with a new one if I break it. Or you can ask me to give you acupuncture once for free."

Cai Xiaolin made a lot of money by changing acupuncture to a helicopter, but he was unwilling to make the profit. However, Li Erdan insisted on doing it, and Xiaoxiao also encouraged Erdan to do it, and even threatened to beat Cai Xiaolin. So Erdan did this very difficult flight action.

A helicopter somersault is similar to a man’s somersault. He rushes first and then turns over in the air. Of course, the flexibility of a helicopter cannot be compared with that of a man, and its operation difficulty is not the same level.

Erdan first pulled up the helicopter. This time, he did not climb on the spot, but rushed forward while rushing forward. The helicopter's degree was getting faster and faster, roaring forward like a flood and beast. The tilt angle of the nose became larger and larger, 3o degrees, 6o degrees,...

Erdan's nerves and muscles were tightly tense, his attention was highly concentrated, and his hands and feet were not messy. He closed his eyes in a slight fright, and his body was close to the back of the chair, and his heartbeat couldn't help but increase. Xiaoxiao screamed exaggeratedly, dancing with his hands and feet, and his two big eyes widened. Cai Xiaolin, who had been very calm, was not calm this time, and took several breaths of cold air, obviously very nervous.

McDonald is still lifting, the degree is still accelerating, the angle is getting steeper, and the shaking of the fuselage is getting bigger and bigger, giving people the illusion that it may break at any time. As the angle increases, nothing fixed in the cabin will fly up, for example, a pack of napkins in front of Cai Xiaolin hits his face. Similarly, under the action of gravity and inertia, the person is close to the back of the chair, and his feet cannot help but rise.

When the inclination angle of the helicopter reaches a critical angle of 90 degrees, that is, the nose of the aircraft is upright, Weiweixiao and Cai Xiaolin both screamed in fear. The helicopter turned upside down and then turned a 360-degree "small bucket" in the air. The process was very short, only a few seconds. The person wearing a seat belt would not fly out, and it felt similar to riding a roller coaster, but it was more exciting.

When the helicopter was turned 18o degrees, the helicopter propeller was downward, and the force transmitted to the helicopter was also downward. At this time, the lateral force of the tail rotor and the torque of the propeller were somewhat unbalanced. The helicopter seemed to be out of control and fell downward! Erdan was in a hurry again, and the nose of the reversing downward slowly pulled up, and finally returned to a flat flight state.

Erdan also had a false alarm and finally completed the action.

Cai Xiaolin, who was still in shock, raised his thumbs up to Erdan and said, "You are awesome! You are awesome! I can guarantee that none of us HK amateur helicopter flight enthusiasts can do this somersault."

"Haha, I can do it so well for the first time. It seems that I am a flying genius!" Erdan said complacently.

"Shenma? The first time?"
Chapter completed!
