Demo flight use: Wind streamer to be flown attached to the engine of a motor paraglider. There's a method of flying by emitting smoke from the engine, but when you actually do it, the propeller and various things get sticky with oil. But this product draws lines in the sky in the same way. It's very innovative. I was very moved when I checked it on YouTube after the test flight. I don't think this product is for sale. I think there's only one in Japan. It's flown by tying it with a string to the bottom of the motor paraglider's engine frame or to the canopy's accelerator, etc. During takeoff, it's dragged along. I think there are only two of these products in Japan. I've seen shorter ones on the internet, but because there are few people who do test flights, I tested it. It's very interesting. And it's very eye-catching. It was about 15 meters long. Takeoff was easy, and it felt natural; it's well-made. If you're so inclined, you can touch the very end of it when you make a U-turn. It's that long. The people watching were full of praise and said it was amazing. When I was in the air, chasing the tail part with a U-turn, I couldn't stop laughing. Please use it so that it doesn't get caught in the propeller. This product is new, and I only tested it once after it was produced. I used to participate in various demo flights, such as the Toba Sky Festa and various local sports days, and I was paid to fly, so I had it for those occasions. The product is only sold through Mercari, so please consider it. Also, I'm not very good at checking my email, so I may be late in getting back to you. If you have any questions about the details, or if you think it looks like a dangerous sport, I want to sell it without any mistakes, so please feel free to contact me.
