The video shows me making and flying the plane.
Step 1: Dismember a Magazine
The first step is to tear off (or cut) a rectangular piece of paper from suitable stock. I am illustrating the process with an old magazine I had lying around.
Step 2: Diagonal Fold
Step 3: Straight Fold
The body of the plane is folded from this large square piece.
The smaller rectangular piece becomes the tail.
Step 4: Cut and Separate the Tail
Step 5: Fold Along the Other Diagonal
Step 6: Turn Paper Over
Step 7: Parallel Fold
Step 8: Magic
If it doesn't, (you're a squib?) just take up that piece of paper and urge it to fold along those three lines, all at once.
The two pictures show the paper on my scanner, and the picture taken by the scanner. It is a great way to document instructables, since the scanner automatically takes care of all lighting and framing and exposure.
Step 9: Fold the Fuselage
Step 10: Fold the Engines
Keep them small if you want performace. Or make them large for your plane to have large mean looking engines.
These add drag, so it is preferable to keep them small.
Step 11: Fix the Tail
Fold the body in half, along the line of the tips of the engines. This fold will also lock the tail in position, and prevent it from taking independent flight when you launch it.
Step 12: Pull Out Engines and Add Dihedral
Put a dihedral on the wings by folding lengthwise. This also stiffens the tail, and makes the plane stable in flight.
Some control may be excercised over the flight trajectory by warping the wings and tail.
Warp the wings downwards to increase lift. Warp the tail upwards to make the plane climb.
Because of the large weight of the plane in relation to the wing area, this is a fast plane, and flights will be short but fast.
Step 13: Launch It!
The plane is best launched by an overhand throw, nose pointed slightly downward. It shoud swoop close to the ground, then climb because of the initial speed, and then level out and settle gently into a descent.
