1. This very symmetric and very square craft is based on divisions by two. It works well with medium to heavy weight paper and is very characteristic of the flying wing style.

2. Make a new crease by folding the left edge of the sheet in to the center line created by the first fold. The first fold divided the sheet in half and this fold divides the half into quarters.

3. Make another new crease by folding the right edge of the top flap back toward the elft to line up with the left edge. This fold divides the top quarter into eights.

4. Turn the sheet over and position it so all the folds you just made are on the right.

5. Make a new crease by brining the left edge over to the right. This divides the top portion of the sheet into half again.

6. Turn the sheet over again from right to left. The extra one eight flaps should be along the left edge now.

7. Take all the layers but one along the left edge and fold them to the right along the existing crease.

8. Flip the paper back over. Fold the upper 2 layers of paper on the left side over to the right side. Use the use the right hand existing interior crease (2nd of 2) as the fulcrum point/line. When finished the paper should appear to be evenly divided, half the page on the left of the crease and half on the right. See additional before and after image:

9. Rotate the paper 180* counter clockwise. Fold the top left corner over toward the center of the left half of the page. Fold the right corner of the left half of the page over to meet the edge of the previous fold. Unfold both corners.

10. Lift and open the top left edge of the page as shown. Flatten the whole section down into a square diamond shape.

11. Repeat the previous 2 steps on the opposite side. When you are finished it will resemble the image here.

12. Turn the paper over again. When positioned properly, the extra flaps are on the left side.

13. Make a new tab by folding all the layers which form a small square at the lower left. The layer beneasth the top layer already has a crease in the right plane.

14. Do the same thing at the end of the paper. Make a new tab by folding all the layers which form a small square at the upper left. The layer beneath the top layer already has a crease in the right place.

15. Fold the entire flap which has the two square tabs just created over to the right. Make this crease as tight as possible.

16. Turn the plane over now end for end keeping the newly folded flaps on the left side.

17. Fold the craft exactly in half by bringing the top edge down to the bottom. Be sure to line up all the edges and make a nice sharp crease.

18. Reposition so that the newest crease is along the bottom edge. The side with all the flaps and layers is to the right.

19. Make the first main wing fold by making a new crease about two finger widths above the bottom edge. This crease should be parallel with the bottom edge.

20. Make another new crease by bringing up the bottom edge. This crease should be parallel to the bottom edge and go through the existing crease in the triangular flap.

21. Turn the plane over from right to left. The flaps and layers are now on the left side.

22. Make the second main wing crease by bringing down the top edge. This crease should match the one beneath it exactly. Make sure to line up all the edges and make a tight crease.

23. Bring up the bottom edge as before to make a new crease. This crease should be parallel to the bottom edge and go through an existing crease in the triangular flap.

24. Open the plane and adjust all the angles so both sides are identical. The wings should be flat to slightly downward in dihedral angle. The vertical stabilizers should be straight, even, and vertical when the craft relaxes during flight.
