After the silent prayer, the last performance is held.

Jin's model flight.

"Now, our guest and one of the organizers, <>, Jin Nido, will perform a model flight.

Amidst applause, the model flight by <> and <> began.

<" is attached is because Jin was busy with various things and could not make a complete new model.

The original <<> has many similar and sister models. The one presented by Jin to the Nordic Federation is also the same type.

However.

"It's not just a Taube, is it?"

Rhodes muttered as he looked at the , which was slowly taking off.

"The coloring is different, too."

As one would expect, Jin was conscious of the fact that it was <> and had changed its coloring. ...... Really, though, he just changed the colors.

After rising about 5 meters above the surface, <> activates its propulsion system.

And then .......

"Oh, wow!　That's a lot of acceleration!"

The people who had begun to prepare for the return trip sat down again.

"That's Jin's plane, isn't it?"

Zion says with a soft smile.

"Hmmm......... this is the difference in technology.......... Our country is behind, isn't it?"

"Oh!　You're as good as the winner, number 9!　That's my boy Jin!"

Mericarance I of the Kingdom of Klein expressed his concern for the current state of his country, while Corwin Raqqa Kiddo, Minister of Magic and Technology, praised Jin.

The Minister of Magic and Technology, Corwin Raqqa Kiddo, praised Jin.

"Yes, it was a spur-of-the-moment operation, but it's going well.

Jin muttered to himself while piloting his doppelganger, Jin D, on Horai Island.

"I guess my plane came last."

This was because he had built a camper-like bungalow, a dining car, and a toilet car.

"But this will do."

The , piloted by Jin D., flies through the late afternoon sky.

Jin-sama's plane is different from the others, isn't it?

"Yes. It's probably only producing 30% or 40% of its power.

Rubina and Grina are in the audience, watching the flight of the .

"...... usually we can get enough performance with half the power, I guess that's the goal."

"I guess so."

Rubina's grandmother, Amanda, who was not very good with technology, was happy to see her grandson enjoying talking with his friends, and she looked at him with a smile.

"Oh, that's Jin-sama!"

The participants in the air race also sensed the potential of the <>.

"Oh, it's going up or ......, but what's that?"

"Is that an auxiliary wing ......?"

Yes, the most significant change Jin made when he finished the was the .

The < can be easily understood as a parachute that can now fly.

Or < or .

Jin knew that paragliders are controlled by pulling a paratrooper-like wing called <> with a string and deforming it .......

He also knew from watching TV that some motor hang gliders have a cockpit that is comparable to that of an aircraft. Many of them have triangular wings, similar to those of kites.

It may be a bit rough to say, but the result of mixing them all together is <>.

One characteristic is that the current <> have wings.

And Marikka used <>, i.e., auxiliary propellers, to change direction. This was only possible because of her magic.

Jin, however, added to this the method of maneuvering <>. In other words, he added ailerons. Or better said, elevons (elevator + ailerons).

The original < had a circular wing with a plate-shaped fuselage attached to the underside of the wing, in other words, like an old pot lid turned inside out.

An auxiliary wing is attached to the trailing edge of the circular wing, which can be used for attitude control.

These auxiliary wings work well when flying at high speeds.

"Master Jin, you're tilting the plane a lot!

"How is he able to do that!"

Rubina and Grina looked at each other.

"...... I'm sure the key is the small moving parts behind the circular wings."

And Rubina's keen eye had almost discovered the secret.

Normally, such < are used for fine-tuning and active attitude change is done by thrusters.

Jin, however, was using both the thrusters and the elevons to achieve the same maneuverability at both high and low speeds.

"Oh, that's Jin-san's plane!"

"So this is the difference between us and ......."

Rhodes and the other participants were also paying attention to Jin's flight.

They knew that Jin's plane, although not particularly spectacular, was both stable and agile.

"...... If Jin-sama had competed, I'm sure he would have come out on top by a landslide."

"That's one more souvenir to take back to <>."

"Yes, sister."

The two technicians from <> seem to have gained a lot.

"Jin-sama makes great things, doesn't he?

"Indeed. It is a far-reaching goal, Grandmother.

Freddy and Elise seemed to have enjoyed the day's racing as well.

"Yes, yes, it's just like Jin. Even though we didn't have much time, this is still a great performance.

At Horai Island, Jin D's friends were also watching the flying of his .

"This is Mr. Jin. It's already different from my !"

Marikka praised Jin.

"Yes, it is. A little closer to an airplane than a blow floater, isn't it?"

Reinhardt agreed.

"If we do it right, it could fly like a tailless plane, couldn't it?"

Hannah looked very interested.

"If that's the case, it's no longer a ," Reinhard said.

Reinhardt said, and Saki spoke up with an idea.

"Kuhu, maybe it's a blowplane?

That's it!

That's a good name!

Saki casually said, "A blowplane.

The day is near when this will become the mainstream of small airplanes and small flying machines in the future. ......?
