"How to use such stability?" Li Zitao was very dissatisfied with the performance of the helicopter and fell down at any time. Nine lives were not enough to play like this.

Besides, the explosion-proof and flame-proof technology of fuel tanks has not yet developed these days. If the rotor suddenly stops, it will definitely be the life of fireworks to set off.

"Boss, we are adjusting its balance device. Now with the real machine, the next adjustment is just a small problem." James McDonald answered easily.

In his opinion, being able to build a truly practical helicopter is a major breakthrough in flight, and Li Zitao's requirements are too high.

But thinking that he was responsible for the design of the helicopter from head to toe, McDonald had the idea that he was too stupid.

Tesla would choose McDonald to be responsible for the helicopter project, which Li Zitao did not expect, after all, he has always been in charge of private jets and business jets.

All are high-end civilian fields, and compared to skunk, Grumman or Douglas, they are more suitable than him.

But now Tesla's vision is correct, and MacDonald really transforms drawings and theories into reality.

"Well, no matter how excellent its performance is, if even basic driving safety cannot be guaranteed, no customer will be attracted to it, think about this more."

As he got on the Wrangler, the car drove straight to the largest hangar at the end of the runway.

Internal number S-4, medium-sized transport aircraft, upper single wing, four-engine, rear large cargo door fuselage layout, all-metal double beam stress-skinned structure.

The machined overall fuselage is strengthened and thickened skin wall panel, and the tail adopts an open design of upper and lower pieces, which can be closed in the air.

The downward slope forms a good airdrop slope, and the landing gear is brought into the streamlined cabins on both sides, ensuring the space and consistency of the main fuselage.

The maximum flight speed is 490 km/h, the maximum range is 2,780 km, the maximum load capacity is 28 tons, and the self-weight is 22 tons.

Internal number s-101, heavy transport aircraft, maximum flight speed 509 km/h, maximum range 3400 km, maximum load capacity 40 tons, and self-weight 33 tons.

Two giants were slowly pulled out from the hangar by a tractor, one in front and one behind. The iron sheet on the surface had not yet been colored, and it emitted silver light in the sun, and traces of steel nails could be seen.

"Charlie, come up." Hughes waved to him on the plane, and a strange hot girl was sitting next to him, waving down through the glass excitedly.

"Have you changed your girlfriend?" Li Zitao looked at Johnson curiously.

"The sixth one." Johnson looked envious. Everyone was busy staying in the experimental center every day, so why could he always find a girlfriend?

After the tractor stopped, Li Zitao boarded the plane from the cabin door on the left, and then passed the narrow upward stairs to enter the cockpit.

The cabin is covered with various instruments and buttons, front, back, left and right, and head full of them, densely packed to make people feel uncomfortable.

There were 5 people sitting in the cabin, responsible for navigation, radar monitoring, contact and engineers. The pilot was Hughes, and his hot girl was sitting in the co-pilot.

"Are you going to fly?" The girl sitting in the passenger seat looked at Hughes with admiration.

"Baby, go to the back...Charlie, come and sit here." After changing seats with the somewhat reluctant hot girl, Li Zitao sat in the passenger seat with a little nervous expression.

He just saw this thing. If he hadn't trusted in skunk technology, he would have already jumped.

"Prepare, we're going to create miracles." Hughes started the engine, and the smile on his face was a little crazy.

Li Zitao suddenly felt something was wrong and said in surprise: "Huces, what time is this test?"

"Of course it's the first time, don't be nervous, I'll take you back safely." As the plane glided forward, Hughes pushed the throttle hard.

"Hold the grass!" Li Zitao had a little more understanding of this bastard's madness.

The picture in front of him gradually tilted upwards, and the feeling of weightlessness hit his heart. Hughes said with a bright smile: "Guys, miracles are right in front of him."

"If you succeed, I know it's OK..." the engineer said excitedly.

When the plane returned to its level, except for the cheers of everyone, Li Zitao could not hear the noise of the machine running. He stood up and tried it without any trembling feeling.

"Are you surprised? Haha..." Hughes blinked proudly.

"Huces...you are a genius, you succeeded." Li Zitao stepped forward and gave him a hug, making Hughe scream: "Oh my god, I'm hugged by a man."

"Man, you should learn to adapt!" Li Zitao cooperated and smiled strangely.

After flying in the sky for 40 minutes, S-4 landed on the runway again. As soon as Li Zitao got off the plane, he heard Johnson's roar: "Huces, you're so messy..."

"It's okay...A great journey, just don't come again next time." Li Zitao said with a smile, "Tonight, we will hold a party in the square, let everyone put down the work at hand, and we will celebrate it together."

...

...

Washington, White House.

In the president's office, the chief adviser, vice president, chief of staff, secretary of state, and director FBI gathered together, but no one spoke.

There was only the rustling sound of the "rustling" sound when the pen in Roosevelt's hand stroked across the white paper in the room.

If anyone who knows this will find that there are fewer important positions among these people, the Chief of Staff of the Army and the Supreme Commander of the Army.

After signing his name, Roosevelt closed his pen cap and put the pen at his hand to raise his head. The deadly atmosphere became more angry.

"Is there any news?" Roosevelt leaned back and relaxed on the armrest.

Everyone looked at each other in a vague way, and Hoover, who was approaching him, spoke, "Mr. President, I insist on my opinion. This matter must be related to that person."

"What about the evidence?" Secretary of State Cordelhull, who was opposite him, asked back: "Do you want to use a secret arrest on him like others?"

"Maybe you can try it, as long as you can pry his mouth open." Hoover said coldly.

"What to use? Electric drill or hammer?" Hull retorted unwillingly.

"I don't think this is a good idea. He is a super rich man and is good at building his own weak identity, passionate about charity, and the families that support him." Vice President John Garner said with a serious expression.

"Everyone, what we are talking about now is the suspect who murdered the Chief of Staff?" Hoover looked at them incredible, as if he had seen a ghost.

"Director Hoover, you have no evidence, even if it is directed, I will agree with your actions, but not just guess!"

Secretary of State Hull looked at Roosevelt and said, "Mr. President, we cannot simply regard him as a minority, Chinese... He has too many interests in him,
