Fast, long range, versatile and equipped with skids, the Strike Hammerhead is a great paper airplane. It is equipped with outrigger, ventral winglets that double as skids, as well as provisions for slats, flaps, rudders, elevators, ailerons, elevons, and air brakes. These provisions make it a capable trainer, on top of its other standard capabilities.
I designed it as a follow-on to the smaller, older Hammerhead paper airplane.
TAA USAF Designation: A115-1
Step 1: Materials
1 Piece of 8.5 by 11 inch Paper
Step 2: Initial Folding and Cutting
Begin by folding one of your paper's corners to the opposite side. Then, cut the rectangular section of paper that is not a part of, or beneath this fold off. Discard the rectangular piece. Then open the fold and repeat it with the other side to form an "X".
Step 3: Corner and Nose Fold
Fold your paper up in half. Then pull two of the corners down to the center fold. Then lay your paper down so that the two corner folds are on the underside. Then pull the nose back to where the corner folds end on the other side of the paper. Then flip it back over and pull the corners in again.
Step 4: Canard Folding
From its previous orientation, flip the airplane over and pull the nose open as shown. Then flatten and crease the paper. Then fold the paper up in half along its center.
Step 5: Wing and Winglet Folding
Fold the paper down so the tip of the canard meets the center fold of the fuselage. Repeat on the other side. Make sure the trailing edges of the wings are parallel with that of the fuselage. Once you've made the creases, unfold the wings with the airplane upside down. Measure half of an inch in from the wingtips along the trailing edge. Fold the wingtips towards the fuselage and make creases at the marks. When doing this, make sure the trailing edges of the winglets are flush with those of the wings.
Step 6: Taping
Tape your Strike Hammerhead at its front, back and over the wing root near the rear. Then tape the loose paper on the fuselage in the place pointed out.
Step 7: Flight
Like previous members of the Hammerhead family, the Strike Hammerhead is a fast, long range, easy-to-fly multirole paper airplane. For the fastest, furthest slights, throw your Strike Hammerhead at about 10 degrees above neutral attitude. In addition, this airplane also has provisions for slats, flaps, rudders, elevators, ailerons, elevons, and air brakes. Enjoy!
