I have a blog that builds rockets. He makes rockets with carbon, paper, and 3D printers. It's in Japanese, but you can translate it into English with the button on the bottom left. http://gallery-h.net/top/

thank you. I will wait for the day when it will be imported to Japan again.

I'm having trouble getting Estes' rocket motors in Japan. Anyone know when production will start?

Thank you for pointing out. Immediately updated my Wordpress site. It's hard for me to make it any more secure.

My fins are made for use with Mach1 and below. I would like to try your method when making a high-speed rocket in the future.

Ever wanted a light fin? If the fins of the model rocket can be made lighter, the center of gravity can be raised and the fins can be made smaller. That is, the air resistance can be reduced. If you make the fins lighter, you can launch a large rocket high with a small motor. I made carbon fins...

I'm using a high viscosity type of cyanoacrylate to glue the 1mm balsa fins. The balsa fins will break before the glue peels off.

A 1/2A6-2 motor is used to launch the rocket, which has a diameter of 25 mm and a height of 250 mm. Thanks to its light body tube, it can reach an altitude of 240ft even with an altimeter.

I made a ring out of styrene foam to hold it in place. By inserting a tight fitting ring, even a thin body tube will be strong enough.

If you use thin paper, it will be weaker, and if you use thick paper, it will be stronger. You can also choose the thickness of the laminating film, from 50µ to 150µ. It will be stronger if you sandwich it between the film from the back and the front like you would with a laminator. However, I...

Diameter 25 mm, length 130 mm.

I challernged big Rocket with B moter. I used styrene paper for body and rings. http://gallery-h.net/top/?p=494

I want to make my body tube slippery and shiny. So I used copy paper and laminator film to make a light and smooth body tube. There is a translation button at the bottom left of the blog, so please have a look. http://gallery-h.net/top/?p=828

I saved the data as an SVG file and created CNC data with MakerCAM. https://www.makercam.com/

Nice flight!

As you all know, Japan is small, so few places can be launched high. My friend has devised a competition that can be challenged even in a small place. It launches a larger aircraft exactly 120 feet using a B-motor. Building a light and large rocket is a challenging project. I launched a rocket...

Thank you. I linked your album to my blog. https://gallery-h.net/top/

Thank you for so many photos. I can use these when creating a new launcher. Look at my piston launcher. This is a B-type motor that launches a light and large rocket. https://gallery-h.net/top/?p=475
