The Skywarrior is a fast, long range and overall very large paper airplane that uses the airframes of two simple airplanes together. I consider this airplane as the paper equivalent of the Boeing B-52 Stratofortress.
TAA USAF Designation: A68-1
Step 1: Materials
2 Pieces of 8.5 by 11 inch Paper
Step 2: Length and Corner Folding on the First Airframe
Begin by folding one piece of paper in half length-wise. Then pull the corners into the center.
Step 3: Sweep Folding
Fold the corner folds down to the center again. Do this on both sides. Proceed to then reverse the folding at the center line so that the aerodynamiclly "clean" is on the outside.
Step 4: Length and Corner Folding on the Second Airframe
Begin by folding one piece of paper in half length-wise. Then pull the corners into the center. Once both corners are folded into the center, reverse the center fold so the aerodynamically "clean"
Step 5: Merge and Tape the Two Airframes
Push the second airframe up to the back of the airfoil of the first airframe. Fold the two up along the center with the clean sides remaining outward. Tape the papers together on the underside where they meet, at the wingtips and center.
Step 6: Fold the Nose and Wings
Spread the paper open and then pull the nose back 2 inches from the "dirty" side to the "clean" side. From here, fold the wings down from about 1 inch above the center fold. Make the wings' trailing edges parallel the fuselage's rear so that there is no angle of incidence.
Step 7: Cut and Fold Your Winglets
About half way along the length of the wingtips, make a cut about 3/4 of an inch into the wing. Proceed to then fold the front winglets up above the wing and the rear winglets under the wing.
Step 8: Taping
The final taping of your Skywarrior is very simple. Tape the front and back of the fuselage together.
Step 9: Flight
The Skywarrior is a larger paper airplane that weighs twice as much as most paper airplanes. Because of its large wing though, wing loading is low and stalls are not a problem until very low speeds. To compensate for this, throw the aircraft fairly fast. In flight, the Skywarrior is extremely stable with its over-under winglet arrangement. Enjoy!
