9. Fold in the lengthwise edges to the center while pulling the nose forward, halving the model's width.

10. The next step is complex. Make sure you take a good look at diagram 11 so that you know where you're headed, and pay careful attention to which folds are dot-coded as mountain folds, and which are supposed to be valley folds! Precrease these folds.

The right part of this diagram shows what will become the rear end of the airplane. Unold that portion of the lengthwise folds back out once again while at the same time folding what will become the nose (at left, above) into the center of the airplane, all the while respecting the small folds coded above as mountain or valley folds.

11. First, carefully fold the diagonals along the nose, and let them spring back up slightly. Then fold the whole nose structure forwards, along the dotted lines which run up and down behind the nose structure. This will rotate a part of it underneath.

12. Then fold the wings up and down as indicated (note the center mountain fold), to get the result shown in figures 13 and 14. Fold up the triangular tabs at the back of the wing only as much as is neccesary for a proper flight.
