How to Fold an Origami Helicopter

Step 1

Take one piece of paper, place it with the desired display side facing up, fold it in half horizontally, leaving a crease, and unfold it.

Fold it in half vertically, and unfold it.

Step 2

Flip the paper from left to right.

Step 3

Fold the bottom right edge to align with the top left edge, and unfold it.

Fold the bottom left edge to align with the top right edge, and unfold it.

Step 4

Mountain fold the left and right creases and bring the left, right, and top points to meet the bottom point. Flatten the fold to get a small square.

Step 5

Fold the bottom left and right edges of the top layer to align with the vertical crease, crease them well, and unfold them.

Step 6

Mountain fold the two creases you made in the previous step indicated by the red dotted lines, bring up the top layer along the black dotted line, and push the left and right corners toward the center. Finally, fold down the top triangle.

Step 7

Flip the paper from left to right.

Step 8

Fold the bottom left and right edges of the top layer to align with the vertical crease, crease them well, and unfold them.

Step 9

As you did in step 6, mountain fold the two creases you made in the previous step indicated by the red dotted lines, bring up the top layer along the black dotted line, and push the left and right corners toward the center. Finally, fold down the top triangle.

Step 10

Fold the bottom right and left edges to align with the vertical crease in the middle, then unfold them 90 degrees so that the two flaps stand vertically. Finally, open the openings of the two flaps and press down the layer in the middle of the paper.

Step 11

Bring up the two edges along the vertical crease as the first picture shows, then lift the bottom point of this flap along the dotted lines [picture 2]. Press down the left and right layers of this flap and fold this flap to the left side [pictures 3 to 5]

Step 12

Turn over the paper from left to right.

Step 13

Repeat step 10, fold the bottom right and left edges to align with the vertical crease in the middle, then unfold them 90 degrees so that the two flaps stand vertically. Finally, open the openings of the two flaps and press down the layer in the middle of the paper.

Step 14

Bring up the two edges along the vertical crease as the first picture shows, then lift the bottom point of this flap along the dotted lines [picture 2]. Press down the left and right layers of this flap and fold this flap to the right side [pictures 3 to 5]

Step 15

Rotate the paper 90 degrees from back to front, and create two mountain creases on the top flap, indicated by the red dotted lines. Then, valley fold its middle crease and flatten the fold.

Step 16

Repeat this for the bottom flap.

Create two mountain creases on this flap, indicated by the red dotted lines. Then, valley fold its middle crease and flatten the fold.

Finally, rotate the paper 90 degrees to lay it flat.

Step 17

Rotate the paper 90 degrees clockwise.

Step 18

Fold the top flap to the left side along the black dotted line, leaving a crease, and unfold it.

Step 19

Rotate the paper 90 degrees from front to back, expand the top opening, fold the right point to the left side along the crease indicated by the black dotted line, and then bring up this point 90 degrees and make a stand upright small flap. Finally, close the opening of the paper and make the opening of this small flap face left.

Step 20

View the paper from the right side and rotate it 90 degrees from front to back, press down the small flap’s top tip and cut it a little. Finally, rotate the paper 90 degrees from back to front to lay it flat.

Step 21

Fold down the top left corner of the fuselage section of the helicopter along the dotted line connecting two red spots. Then, rotate the paper 180 degrees from left to right, and fold down the top right corner along the dotted line connecting two red spots.

Step 22

Fold the bottom right corner of the top layer backward along the red dotted line, and fold up the bottom right corner of the bottom layer along the black dotted line.

Step 23

Take out another piece of paper and place it with the desired display side facing down. Fold it in half horizontally, leaving a crease, and unfold it.

Step 24

Fold it in half vertically, leaving a crease, and unfold it.

Step 25

Fold the right edge to align with the vertical crease, leaving a crease, and unfold it.

Step 26

Fold the bottom edge to align with the horizontal crease, leaving a crease, and unfold it.

Step 27

Fold the bottom edge to align with the crease you made in the previous step, leaving a crease, and unfold it.

Cut the paper along the creases indicated by the dotted lines, as you can see in the third picture.

Step 28

Fold these four paper strips in half horizontally from bottom to top.

Step 29

Glue them together in pairs to get two crosses.

Step 30

Glue the larger cross on top of the helicopter as the main rotor.

Step 31

Glue the small one to the tail as the tail rotor.
