Large index cards, usually 5 inches (12. 7 cm) by 7 inches, work really well for this project. Use one if you already have some at home.
These measurements do not need to be totally exact, so don’t worry if you are a little bit off. What matters is that the paper is much longer than it is wide. Is possible, draw your lines using a ruler so your cuts are straight.
This is not totally necessary but may help you to make a good helicopter.
If you drew the guide lines on your paper, be sure to stop cutting at least a half an inch before you get to the middle line. This will assure that you do not accidentally cut too far.
Once again, the guide lines you might have drawn on your paper may help you. When cutting these horizontal cuts, be sure not to cut so far that you reach the middle line. It’s best to only cut halfway to the middle line on both sides you are cutting. This will assure that the bottom of your helicopter doesn’t get cut off!
Once you have folded and creased them, open these flaps up halfway. They have now formed the wings of your helicopter.
Experiment by dropping it from different heights. See if the way it flies changes. [1] X Research source Use various sizes of paperclips, see which works best. You can also cut the wings, so they are thinner or thicker, to get the best flight.
The width of your index card will now be one quarter what it was to begin with.
Once both sides are folded, open them both up halfway. These folds have now formed the wings of your helicopter.
