Instead of flying, "soft floating" ultra light model planes in the sky in the sky festival!

Although I think that the airplane is fast, I think that the Ultra lightweight model plane that was exhibited in "Air Festival!" Which was held on March 6, as if the soap bubbles are drifting in the air, You can skip it.

However, the technology that seems to be leisurely flying and supports it is a word of fine. The level of work that you want to say is saying "Are you doing this really in a hobby?" That it is a radio control by combining a wire like a hair like hair and a much smaller receiver than a 100 yen coin is being done It was.

Details are below.

Here is how it actually skips various model planes. It is not elegant like a paper airplane with a huge wind flying and flying as if it is floating and moving by the flow of air.

Multi-wing aircraft capable of earning lift at a slower speed.


like thisBalsa woodThe balsa-made aircraft that used it requires considerable craftsmanship to assemble and it is quite difficult for beginners. Initially it is recommended to make it with styrofoam which has a specific gravity of about 1/6 as compared with balsa wood and is easy to process lightly. Although the initial cost seems to be about 30,000 yen including electronic parts etc., it seems that it can be made much cheaper from the second aircraft.

The heart of the aircraft. It has only FM receiver, motor, battery connector with only this part. It seems that the receiver weighs less than 1 g.

The flying figure is no longer a creature. It makes me think of a bird that fly orbiting in search of prey.

Mechanism such as crank which makes flapping is also compact anyway.


Aircraft that saved uselessly was full of functional beauty.


From above.


This is a battery. It is possible to fly for about 5 minutes at this size.


Even though it is a small battery, it seems to be a good weight for this class of aircraft. It is attached to the rear part considering the center of gravity position.


There is also such a tiny ultra small flap.


Infrared as well as radio waves were used for remote operation. It seems that the black walls and the walls of the glass wall are slightly weak because they are communicating using the infrared reflection from the wall.
