The Pteroplane is a little stunt plane that comes alive in the air with loops, swoops, and spins. It’s named after the pterodactyl dinosaur because of the way it looks and flies. Just kidding. I have no idea how a pterodactyl flies. They became extinct right before I was born.
Step 1: Start with a regular piece of rectangle paper 8.5 x 11.0 inches (215.9 x 279.4 mm).
Step 2: Fold the left half to the right.
Step 3: Unfold. We need the crease.
Step 4: Now fold the top two corners to the center to form a triangle at the top.
Step 5: Fold the triangle down.
Step 6: Fold the bottom part up, creasing at the bottom tip of the triangle. Run your fingernails along the crease to get a good sharp fold.
Step 7: Unfold.
Step 8: Turn the paper over and fold the bottom part up again at the crease line. Again, run your fingernails along the crease to get a sharp fold.
Step 9: Unfold.
Step 10: Turn the paper over.
Step 11: Tear or cut off the bottom part. Keep this rectangle piece; we will need it later for the tail.
Step 12: Fold the bottom point of the triangle to the center of the top edge.
Step 13: Unfold.
Step 14: Fold the top two corners to the center indicated by the black arrow. The center is where the creases form a cross “+”.
Step 15: Keep the left and right sides you just folded flat down, then fold the bottom point up as shown.
Step 16: Unfold to reveal the crease you just made.
Step 17: Fold the top edge to meet the crease you made.
Step 18: Fold the bottom triangle back up to lock the flap.
Step 19: Turn the paper over.
Step 20: Fold the left half to the right.
Step 21: Take the rectangle piece that you cut or tore off earlier in step 11, and cut or tear it in half. Keep one and throw the other half away.
Step 22: Fold in half from bottom to top. This will be the plane’s tail.
Step 23: Bring in the plane’s body and rotate it counterclockwise as shown.
Step 24: Slide the tail all the way into the pocket of the body.
Step 25: Fold the wing and tail down at about a pinky’s width of the tail.
Step 26: Turn the paper over and fold this wing and tail down to line up with the other wing.
Step 27: Open the wings and your plane should look like this.
Step 28: Before flying the plane, make sure the wings and tail are tilted like this. This will help make it fly better.
Step 29: Hold the front of the plane like this and throw it fast at an upward angle.
Step 30: To make it perform other stunts, you may pinch up or down the back of the wing near the tail like this. Pinch one wing or both and see what it does!
