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

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 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 made a tower launcher for 18mm body tube. It was easy to fix the rail to the 18mm aluminum pipe. Look at the blog. https://gallery-h.net/top/?p=564

I made a rocket to compete for altitude. The standard is 18mm in diameter and over 200mm in height. The motor is A8. I was careful to make it light and small. https://gallery-h.net/top/?p=548

I made a tower type piston launcher. A B6-4 motor will launch a rocket with a diameter of 114 mm and a total height of 1500 mm. I write in Japanese, but I want you to translate it with the orange button in the lower left. https://gallery-h.net/top/?p=475

To make a lightweight model rocket, it is effective to lighten the lower end of the rocket. So I made it with styrene board and paper. I've written it on my blog, so take a look. There is an orange translation button in the lower left. https://gallery-h.net/top/?p=440

made a light nose cone. Few people want a light nose cone. This is because the center of gravity is lowered and the aerodynamic center must be lowered. However, I designed an aircraft that makes use of a light nose cone. Look at the blog. (You can translate with the orange button at the bottom...

I challenged to launch a rocket with a diameter of 114 mm and a height of 1300 mm up to 40 m with a C6-4 motor. The result was 38.1 m. I want you to see a blog. (You can read the translation with the button on the lower left) https://gallery-h.net/top/

The blog featured a rocket contest sponsored by Uematsu Electric in Japan. (Translate with the button on the lower left) https://gallery-h.net/top/?p=405 It is a competition that brings the largest aircraft as close as 40 meters high. Even if you can not come to Japan for the competition, it is...

Uematsu Electric Co., Ltd. will host a competition for model rockets. There is a roster competition and a rocket competition there. In model rocket competition, we compete how large a rocket can be launched at an altitude of just 40m. I challenge it to test launch. I wrote about it on my blog...

Introducing Japan's Rocket Builder. Tsutomu Uematsu's company aims for space. As well as research on practical rockets, he conducts rocket education for children. Try a papercraft model rocket. These can be launched with an 18 mm motor...

I tried to make a model rocket for high altitude competition. I want you to see a blog. I am writing in Japanese, but there is a translation button in the lower left. https://gallery-h.net/top/?p=273
