Long range, stable and simple, the Turbo Skystreak is a great glider that can be made by almost anyone. This airplane's high aspect ratio allows it to get a supreme glide ratio, and as a result, its one of the best gliders I've ever seen. If launched from a tall building, this plane could conceivably fly hundreds of feet.
TAA USAF Designation: UF225-1
Step 1: Materials
1 Piece of 8.5 by 11 inch Paper (Makes 2 Turbo Skystreaks)
Step 2: Length Folding and Cutting
To start, fold your paper in half along its length. Then unfold and cut or tear along the crease. Now separate the two pieces and choose which one you want to use. (Note: 1 piece of 8.5 by 11 inch (A4) paper can make two Turbo Skystreaks).
Step 3: Fourth Folding
Fold your paper in half along its width, and then its length.
Step 4: Counterweight Folding
Now fold the top length half down to the center length crease. Then fold this fold in half. Now overlap this and repeat until the counterweight fold is on the other side of the length fold.
Step 5: Making the Fins and Taping
Begin construction of your fins by folding your airplane up in half. Then 3/4 of an inch (0.75 inches) in from the wingtip along the trailing edge. Then measure 1/2 of an inch (0.5 inches) in from the trailing edge along the wingtip. Then measure 3/4 of an inch straight into the wing from the mark you made along the trailing edge. Connect this mark to the one you made it from, and then along the wingtip. Then cut along the second line.
Step 6: Taping and Fin Folding
Tape your Turbo Skystreak along its counterweight. Then fold its fins up, with their trailing edges parallel to that of the wing.
Step 7: Flight
Like the Skystreak before it, the Turbo Skystreak is a simple glider with great potential. As far as launch goes, hold the aircraft along its center crease and release at a slow to moderate speed. Addition surfaces that can be applied to the basic airframe include spoilers, spoilerons, elevons, ailerons, elevators, and rudders. Enjoy!
