Modified Standard Paper Airplane

copyright- Roger Weller 2011

 

The original paper airplane was probably invent by Leonardo da Vincini. 
A sketch of the standard paper airplane was found among his works. 
This is the most common paper airplane that children learn to make. 
The flight characteristics are somewhat disappointing because the
airplane tends to nosedive instead of smoothly gliding.
 

By making a few very simple changes in the folding pattern a very
satisfactory glider can easily be made
.  The best paper is either simple,
cheap, loose leaf paper or a lightweight cheap copy paper.  Heavy, high
quality copy paper does not hold folds very well.

5. The key modification appears in step 5.  The wings need to be larger than
the body.  This can also be observed in step 7.

7.  Wings larger than the body can also be seen in step 7.

8.  A final step is to fold the wing tips downwards.  This adds to flight stability.
It is important to make sure that they wing tip folds are
parallel to the
body of the airplane.  If crooked the plane will twist to the right or left.

When throwing the paper airplane, the wings should be in a "Y" shape
when the body is pinched by
your thumb and forefinger.
