Very fast, long range and simple, the UltraHavoc is an improved variant of the StratoHavoc. The aircraft is designed to glide quite far at high speed, while requiring few supplies. The UltraHavoc is an ideal choice for those looking for a classroom cruiser or backyard buccaneer.

Development of the UltraHavoc began shortly after the publication of the StratoHavoc. The StratoHavoc had taken advantage of some developments made to improve the performance of the Nakamura Lock. Work on this project (a collaboration between my friend,Paper Artland and myself) continued to develop new refinements after the StratoHavoc's release and again I decided to test their adaptability to existing Nakamura Lock derivatives. I found the new nose lock fold to be applicable and a considerable improvement to the design of the StratoHavoc. The prototype UltraHavoc was found to be a worthy design and was cleared for publication after proving itself in its flight testing

TAA USAF Designation: A126-3

Step 1: Materials

1 Piece of 8.5 by 11 inch Paper





Step 2: Length and Corner Folding

Fold your paper in half along its length. Then pull the corners into the center. After making creases, unfold and pull the edges of the paper into themselves. Then restore the original corner folds as shown.

Step 3: Nose Folding

Pull the nose of the aircraft down until the edges of the corner folds are the endpoints of the new crease. Measure 1 inch ahead of the tip of the nose tip. After doing this, pull the corners of the paper into the mark as shown, then unfold. After doing this, pull the edges of the folds into the creases the folds have made as shown. Restore the first creases of this step as shown, then pull the triangle forward and fold the airplane along the center crease to secure the paper.

Step 4: Wing and Winglet Folding; Taping

Measure 0.875 inches above the center crease along the trailing edges of the wings and make a mark. Once this is done, measure 0.875 inches from the wingtips along the trailing edges of the wings and make marks. After making these marks, fold the wings down at the first mark. Maintain an angle of incidence of zero degrees by aligning the trailing edges of the wings with that of the fuselage. Once the wings are folded, move on to the winglets. Fold them down at the second marks you made; align their trailing edges with those of the wings to keep them parallel with the fuselage.

Bend the fuselage leading edge up to the wing root folds, then tuck the paper into the fuselage as shown. Once this has been done, pull the paper backward as shown. Then fold the wings down. The fold at the front will lock the nose together. Tape where designated. This will complete the aircraft.

Step 5: Flight

The UltraHavoc is, like its predecessors, very easy to fly. At launch, give the airplane a moderately fast throw for optimal flight speed and range. Additional surfaces applicable include flaps, elevators, ailerons, elevons, rudders, air brakes and an electronic warfare tail. Enjoy!
