In the process of transforming the MiG-29, what made Darren feel depressed was not the problem of the spell, but the inability to ensure consistency, like all handmade products, although for a single item, meticulous work can obtain extremely high quality, but to make a bunch of exactly the same thing, handmade cannot be guaranteed, this is the biggest difference between handicraft and industry.

This kind of inconsistency may not be a problem on the flying broomstick, but when it is applied to an object as large as the MiG-29, a slight difference will act on the whole, not to mention that in order to improve flight performance, Darren also strengthened the magic with the four longitudinal beams in the MiG-29 fuselage, and when their output is inconsistent, this difference in power will be directly applied to the fuselage and tear the aircraft from the inside!

For this reason, after searching for information in many ways, Darren had to buy a complete set of dragon nerves at a high price and use them to connect the planes for balance according to a note from the Black family used to guide the large-scale transfiguration, which can be regarded as partially solving this problem.

Another problem is the interactive interface, unlike the flying broomstick, the total flight is not much higher than the ground, let alone how fast it flies, I don't know the height and speed for the MiG-29 aircraft of this size, it is simply unimaginable, simply put, the pilot feels more than two meters from the ground, in fact, the fuselage has hit the ground.

Of course, this situation is more extreme, but there is simply no creature in nature that has evolved a coping mechanism that can cope with the situation at speeds of more than 300 kilometers per hour, otherwise the plane will not keep hitting the birds, because the birds will not be able to react at all.

For people, it is manifested as a vague sense of spatial change, and even after professional training, it is difficult for pilots to visually judge the exact speed of a high-speed flying aircraft, for the same reason, the brain is not prepared to process this information at all, only fast, very fast, very fast......

Compared to the MiG-29, which has been criticized for its backward electromechanical system, the wizarding world is simply a blank in this regard, let alone a monitor, not even a reliable instrument, and in the end Darren can only go to a store that makes magic telescopes at a high price and order a batch of lenses that can provide flight data through various conversions, by this time, he and Fred and George are already very good at finding alternatives in the wizarding world.

For example, the gyroscope that displays attitude on the plane, Darren and the twins used magic to fix a balancer that would maintain absolute level to replace it, and then used the lens to project it onto a mirror that simulated a heads-up display.

The airspeedometer, on the other hand, finds a spell to measure the speed of the wind, and then increases its range considerably, otherwise it is definitely not enough.

After a series of such self-reliance, Darren was able to come up with a system that could provide the plane's basic attitude and data, so that he would not be at a loss after leaving the ground too high.

Any pilot knows that in the absence of a reference, especially under the influence of clouds and light, people are prone to all kinds of strange illusions, such as tilt illusions, pitch illusions, anti-rotation illusions, Illusion of azimuth, in extreme cases, even the illusion of flying backwards, feeling that the plane is head-down, but in fact the plane is flying normally, in this case, the importance of the on-board instrument is reflected, every pilot will be told that when the individual feels conflicted with the instrument, you must believe in the instrument, if the pilot can not rely on the instrument to overcome the illusion, it will bring serious consequences, and even the plane is destroyed!

Darren didn't want to get dizzy and fly the plane to the ground......

During this period, Fred and George gradually exposed their shortcomings, although they can always come up with good ideas, but in the process of transforming into real objects, they will find that there are many problems limited by the lack of theory and knowledge, which cannot be solved, often Darren has to go to Percy for help, and then follow Percy's prompts to rummage through the boxes and cabinets to find information, and even ask Kreacher to go to 12 Grimmauld Place to find it.

Later, because Darren's questions were so unpopular, even Percy's curiosity was attracted to find out what they were doing, which Fred and George firmly refused.

"If you let him know that we're doing magic on Muggle items, then I'll tell the Ministry of Magic about it!" Darren agreed.

It's just that the sight of the twins trying to study books made Mrs. Weasley sigh with emotion, saying that if the time o.w.ls the two guys had half the effort they have now, they wouldn't have been like that, and said many times that if Darren had been brought in a year earlier, maybe it would have helped the two sons in their studies.

In this regard, Darren can only hehe, last year it was the Weasleys who went to Egypt by themselves, besides, a year earlier, there was no such a big project, these two MiG-29s were only obtained during the Christmas holiday, and he prepared for this for half a year before he started, and if there was no information that Blake helped him get, it would be useless to wait for another half a year, unless he planned to build a vintage plane as slow as a flying car!

As for saying that Fred and George will work so hard, it can only be said that interest is the best teacher, and they have not done well in their previous studies, but they have not found something that can arouse their interest enough......

Finally, in order to cause as little trouble as possible, in addition to the flight function, Darren also borrowed from the flying car, and asked Kreacher to prepare the same stealth function for the plane, according to his estimate, the flying car can not only be optically stealthy, but also evade radar by interfering with electromagnetic waves, otherwise the flying car would have alarmed the air defense system a long time ago when flying in the city and flying to Hogwarts, and the radar reflective surface of the big iron shell of the flying car is not ordinarily large.

In addition, in order to avoid causing trouble for Mr. Weasley, Darren never mentioned the plane to him, but according to Fred and George, Mr. Weasley was actually very interested in their actions, and many ideas were obtained from him......

Finally, after testing the control system and magic feedback again, it was time for a full test flight, where Darren had only hovered and moved slowly indoors, and was now finally able to test how it would perform at full power. (To be continued.) )
