How to Make a Paper Helicopter from A4 Paper

Wow, that’s awesome.

It’s flying so high and still spinning.

Damn, it’s flying! Damn, as long as you have hands, you can make this paper helicopter that makes classmates cheer.

So it’s this simple. Cut an A4 sheet lengthwise into a quarter, similar size and proportions are fine.

Vertically divide the top half into two equal parts, the bottom half into three equal parts, and cut with about a one-centimeter gap between.

Fold the two sides of the bottom part toward the center, roll the bottom up twice, and you can fold both sides out a bit to secure it.

This prevents it from coming loose and lowers the center of gravity. Gently pull the top blades to both sides to open them.

This super simple paper helicopter is done. Updrafts often form along the outer walls of buildings.

As long as you throw it, it can fly higher and higher. You can also make your own updraft at the corner of a wall at home.

Then these little helicopters can just keep flying. Have you learned it? Hurry and try it yourself.
