NOTE: This design requires a paperclip on the nose to fly properly.

This interesting looking square craft works best with light to medium weight paper. Start with a letter size sheet.

1. Start with a medium to heavy weight sheet of letter size paper. Fold down the upper right corner so the upper right points hits the lower left point.

2. Rotate the paper around so the creased side is on the left and the paper opens up on the right side. Fold the top point down so it hits the bottom point. When folded correctly, all o the outside edges should line up.

3.Unfold all of the creases just made so the paper is completely open and is flat on the working surface.

4.Rotate the paper around so the longest diagonal crease goes up from left to right across the paper. Fold the top point (which does not have a crease going to it) down so it hits the bottom point.

5.Rotate the paper around so the creased edge is to the left and the paper opens up on the right. Fold the top point down so it hits the bottom point. When folded correctly, all of the outside edges should line up.

6.Unfold all of the creases you just made so the paper lays flat on the working surface.

7. Flip the paper over and rotate it around so the long edge of the paper is horizontal .

8.Fold the paper exactly in half along its long edge. Unfold after the crease has been made.

9.Flip the paper over and rotate it around so the short edge of the paper is horizontal.

10.Fold the paper exactly in half along its short edge. Unfold after the crease has been made.

11. Rotate the paper around so the long edge is at the top.

12.Pop the horizontal creases up and fold in and down towards the bottom of the paper. The hinge for the fold should be about the diagonal creases with points at the lower left and right corners of the paper.

13.Fold the points at the top of the flaps sticking up from the plane's main body, out and down towards the wing tips. Press the point at the tip, where the flaps meet, straight down to the center line crease.

14.Fold the nose down so the point at the tip of the nose hits the bottom edge of the paper. Be sure to keep the center line creases lined up for good balance.

15. Fold the first three layers of the plane back and down. Two new creases should be created as hinges on each triangle between the layers. Be sure to keep the horizontal center line creases line up on the top-most triangles.

16.Fold the top edge of the paper back and down so the top edge hits the horizontal center line crease.

17. Rotate the plane around so the nose is pointing to the left. Fold the plane in half about the existing center line crease. Be sure to line up the wing flaps for good balance.

18.Make a crease to fold the aft wing tip over. When folded correctly, the newly formed triangular flap should be about the same size as the triangle uncovered by the fold. The size of the wing tip fold is not too important.

19. Flip the plane over so the wing tip just folded is underneath.

20.Fold the second wing tip back and down so it lines up with the first wing folds is not too important. However, making them the same size is important.

21.Rotate the plane around so the wing tips just folded are up to the right.

22.Make a crease for the first wing flap. The left point of the crease should be at the tip of the nose. The right point should be about three fingers widths up on the tail. When folded correctly, the bottom edge of the fuselage should line up with the bottom-most layer of the wing flap.

23.Flip the plane over and rotate it around so the first wing flap is underneath and the nose points to the right.

24. Make a crease for the tail fold. The upper point of the crease should be where the wing flap meet at the left. The lower point where several layers meet in the lower right corner of the plane.

25.Unfold the tail fold just made.

26. Fold the second wing flap down. Be sure to line up the wing flaps for good balance.

27.Flip the plane over and rotate it around so the nose is pointing to the left and the wing flaps are pointing down.

28.Make a crease to fold the forward wing tip over. When folded correctly, the newly formed triangular flap should be about the same size as the triangle uncovered by the fold. The size of the wing tip fold is not too important.

29.Flip the plane over and rotate it around so the wing tip just folded is underneath and the nose is pointing to the right.

30.Fold the other wing tip back so it lines up with the first. The size of the wing tip folds is not too important, however making them the same size is important.

31.Rotate the plane around so the nose is pointed up and the wing flaps are pointed to the right.

32.Unfold the first wing flap; there are two layers to unfold. Extend both layers out to the right and press flat down against the working surface.

33.Pop the tail section fold in, while folding the wing flap back in on top of itself. When folded correctly, the tail section will be completely hidden from view by the inner layer of the wing flap.

34. Open up the wing flaps and adjust the wing angles for good balance. Set the dihedral angle to be flat. Some tape across the top of the fuselage and on the bottom of the wings will reduce drag for better flights.

35. Extend the fore and aft wing tips. These act as vertical stabilizers and may be adjusted separately to control the flight of the plane. It is best if they are perpendicular to the wing surfaces.

36. Place a long paperclip on the front of the plane, to help it's balance.
