A seemingly simple yet surprisingly complex toy
It was much more difficult to design than my other toys. I tried many times.
This made me realize how great the invention of human aircraft truly is.

This rocket can perform a short vertical flight.
It looks similar to a helicopter's principle, but it's not very related.
The coaxial contra-rotating propellers on this small item are merely a visual effect.
Key points for making:
After printing, make sure the rotating shaft is smooth and doesn't get stuck.
Using thicker and wider rubber bands will yield better results.
If you find it doesn't fly after assembly, it's definitely a problem with the rubber band.
To keep the model lightweight, various parts are fragile, so please do not squeeze it hard when playing.
The rubber band needs to be wound very tightly to achieve a good flight effect, so if your rubber band is not thick or good enough, it might break.
