How to fly the best paper airplane in the world

Preflight inspection -
Before you fly the model plane for the first time you should examine it carefully looking directly at the front and the rear. Just like a real airplane, the left and right side must be the same, that is a mirror image of each other. If one wing is higher then the other or the surfaces are not at the same angle, or the tail is crooked, then the plane is likely to fly poorly. Make any adjustments to correct these problems now.

Flight techniques -
This is the fun part, learning to fly. The airplane can be launched with force or softly. Launching it on a windy day directly into the breeze causes it to climb into a half barrel roll. For a second it will fly upside down and then flip over and fly a long distance with the wind. On calm days you can launch it gently horizontally. It has a long glide path and will generally go in a straight line or go into a gentle curve.

Fine tuning -
If you find that the plane is banking to the left or right, you can correct this by experimenting with bends on the control surfaces. To gain extra control, cut flaps on the rear edge of the wings and bend the flaps up or down as needed. You can also try bending the wing tips down instead of up.

The tail flaps can be bent up slightly if the plane tends to dive. All changes should be made with small adjustments and then a test flight to analyze the change.

Make more than one model airplane. You will find that they all have unique flight characteristics, no two are alike. Choose the one that flies best and try to find out why it flies so well.

Try making really large versions of this plane using construction or ledger paper. They fly just as well only higher and farther.
