These are the complete instructions to make an awesome paper airplane that does stunts. All you need is one sheet of paper! (This is my first instructable, so please leave suggestions in the comments.)
NOTE: This plane is not a dart, so it won't fly if you throw it too fast. Also, as with any paper airplane, a tiny mistake could cause it to curve in flight.
Step 1: Materials
All you need is:
1 piece of paper.
A hard work surface (like a table).
Step 2: Crease
Crease the paper in half lengthwise, and then unfold.
Step 3: Making the Tip
Fold the top corners down to meet the crease in the middle.
Step 4: Folding in Half
Fold the upper part down, so that the tip is touching the bottom of the center crease. Basically, you are folding the paper in half downwards.
Step 5: Fold Corners Down
Fold the corners down, just like you did in step 3.
Step 6: Fold Tip Up
Fold the tip that is sticking out from between the corners up.
Step 7: Fold Top Tip Down
Fold the top tip down, so that there is 3 inches left at the bottom (see notes on the picture)
Step 8: Flip the Whole Thing Over
Flip the whole thing over, so that the side without any folds is up. check the pictures to get a sense of what your plane should look like at the moment.
Step 9: Fold in Half
Fold the plane in half so that you can see the fold of the plane.
Step 10: Fold the Wings
Fold the wings down. Look at the pictures to see how.
Step 11: Fold the Stabilizers
Fold the stabilizers up. These keep the plane from spinning in the air.
Step 12: Put the Wings Up.
Fold the wings and stabilizers up, so that it looks like a normal paper airplane.
Step 13: Finishing Touches
Now you should add some elevators. These are little flaps on the back of the airplane that are pushed up. Elevators add lift to your aircraft. Having a lot of them causes enough lift to make the plane do a loop in the air.
Step 14: Throwing!
Now you have a great stunt plane in your hands. But how does it do stunts? This is a crash course on how to pilot this paper airplane.
First the very basics. You have to throw this plane slowly to have a stable flight. If it dives, put the elevators up higher.
Now for some tricks.
To make it do a small stall, and then flip over and glide down, throw it almost straight up, just a tad forward.
For a large loop, throw it straight up, but this time a little backwards.
To make it do dips, throw it straight.
Remember, with all of these tricks, throw it slowly!
