| This airplane is designed around a letter-sized (8.5”x11”) piece of regular copy/printer paper. It flies best using these proportions of paper. The paper should be dry and absolutely wrinkle-free. | Fold the top right corner to meet the left edge of the paper. This fold is approximate - Segment A should be between 1 and 2 inches. Don’t overcrease this fold, it is the right wing’s leading edge. | Fold line A over to line B along the dotted line. Matching A and B very well is important as these will be the wingtips. The shaded area in the second diagram is going to be the right wing. This fold will be a guide for step 4. | Using line A (the right wing) as a guide, fold over the upper left chunk of paper along line A. Don’t over-crease this fold, either. You are now creating the leading edge of the left wing. |

| Unfold the last two steps. You can now see the aspect of the airplane start to reveal itself. The leading edges of the wings are lines A and B. | Re-fold along line A. | That piece hanging off the top of the nose looks lame...fold it back underneath the rest of the paper. It’s actually pretty important for weighting the front of the plane. | Fold the pointy nose down so the point just goes past where the paper crosses itself in the middle, and then fold the plane in half. By now, the nose section is getting pretty thick with paper and it’s OK if things aren’t as accurate in front. |

| Fold down the left wing. It’s important to get a slight sloping angle to the wing’s incidence - segment B in the tail needs to be a bit “taller” than segment A in the nose. | Flip the whole plane over. Fold down the right wing by matching it as closely as possible, wingtip to wingtip with the left wing (A to B). Accuracy in matching the wingtips together will really help balance flight characteristics. | Fold the right wing vertical stabilizer up from the wingtip. Match the rear (trailing) edge of the stabilizer with the trailing edge of the wing. | Flip the plane over and fold up the left wing vertical stabilizer. It is critical to fold this stabilizer so that the fold line matches the fold line on the other stabilizer closely, otherwise your plane will have strong turning tendancies. |

| Open up the wings, stabilizer and keel folds so that the plane looks about like this. Good work, you’re done folding! An airplane is never finished, though, until it’s tested and trimmed for neutral flying. |
