This model is a common toy that flies a propeller.
What makes it different from other similar toys is that its shape resembles a real helicopter.

At first, it was modeled after the helicopter from the very old TV show Airwolf, but the proportions were simplified a little bit considering the grip.

You can operate the propeller by attaching a pull cord to the tail, and you can also display it in the form of a helicopter without the pull cord in normal times.

It looks even better when the body is printed in two colors.
