Thank you, retortec.
I am planning a piston launcher that moves the inner tube.
We believe that the adverse effects of sputtering can be reduced...
This looks very good.
I want to try your idea as a piston launcher for a small rocket.
Apart from that, I am thinking of a new piston launcher for...
No.It's not a piston launcher.
The rocket only slides in the three rails.
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.
The rocket is heavy but sturdy and can be enjoyed by flying it over and over again.
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...
Piston launcher ignition system
In the Apogee kit, the igniter's fine wire is drawn from the gap between the cylinder and the motor and wired with...
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...
I am making it to launch the rocket with a B6-4 motor.
In order to fly 40m, it must be kept under 70g.
If they are made with the same weight, the...
I will challenge the contest to launch the largest rocket as high as 40m....
In Japan, I can buy a styrene board cheaply.This is very convenient.
Certainly it is very similar.
I calculated with Calc of googleDrive and plotted with Inkscape.
The files used are published on GoogleDrive....
Thanks for your advice.
However, since the fin base strengthens the structure, it needs to be firmly bonded to the ring and outer shell.
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.
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...

Or was it hard to understand my post?
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...
The blog featured a rocket contest sponsored by Uematsu Electric in Japan. (Translate with the button on the lower left)...
I found a site like this.
I will try it.
