A good, long distance flyer.
Step 1: You Need...
A piece of A4/letter paper, a bit of tape, and hands, feet, or another folding method.
Step 2: Let's Get Folding!
Fold your paper in half, lengthwise, and then across the diagonals. Then fold the left edge along the diagonal line. Fold back the flap that is overlapping the centre crease. Repeat on other side.
Step 3: Fold It!
Fold the nose down where the crossing of the second and third folds were, and then fold these down. Fold up the flap, which will hold these in place.
Step 4: The Finals
Fold in half, and then fold the wings so that they touch the tail corner. Tape where needed and add dihedral. This one can fly really far.
