Introduction: How to Make the StratoUltraceptor Paper Airplane

About: Paper airplane maker: 400+ designs so far and more in development!

Fast, long range and small, the StratoUltraceptor is a refined variant of the Strike Ultraceptor with a simplified trailing edge shape for easier handling.

The StratoUltraceptor was developed in late summer 2015 as a more conventional complement to the Trident. To improve the aircraft's performance as an interceptor, the rear portion of the aircraft was redesigned quite substantially and the wing loading was increased. The aircraft's shape was more regular with this change, so it performs excellent in the air and also handles better when on the ground. After testing the new StratoUltraceptor, I found its performance to be good and approved it for publication, though the larger Hunter was published before it due by viewer request.

TAA USAF Designation: F300-4

Step 1: Materials

Required:
1 Piece of 8.5 by 11 inch Paper

Tape

Pencil

Ruler

Optional:

Scissors

Step 2: Width and Canard Folding

Fold the paper in half along its width. Then on one of the halves, fold the corner down to the center fold. Then repeat on the other side. Once the creases have been established, unfold each. Then fold the paper folds into themselves as shown. Then fold again. Once this is finished, unfold the paper. Pull the corner folds over the center crease and allow them to remain there. Unfold and then pull the corners at the rear inward; after doing this, pull the outer edge into the crease you made previously as shown. Repeat on the other side. With this done, pull the rear trailing edge in over the existing folds as shown on each side.

Step 3: Airfoil and Canard Folding

Pull the paper of the previous fold back to align the former leading edge with the crease made by that same fold. Perform this on both sides. After doing this, unfold this, then pull the crease that has resulted into the first crease. Refold the paper along the original crease on each side. After doing this, pull the paper back over the center crease on each side. Pull the tip of the nose backward so the apexes of the diamond are the tips of the fold. Line up the folds to find the rear edge of the nose fold; pull what overhangs forward again. After all of this is finished, tuck the paper into the nose as pictured.

Step 4: Canard, Wing and Winglet Folding; Taping

Fold the aircraft in half, then fold the canards down. After the canards are folded, fold the wings immediately above them. Align the trailing edges with those of the fuselage to maintain an angle of incidence of zero degrees. Measure 0.875 inches from the wingtip and fold them at the mark. Align the trailing edges of the winglets with those of the wings.

Step 5: Flight

The StratoUltraceptor is a rather conventional dart paper airplane and flies very much like the previous Ultraceptor variants. The Strike Ultraceptor can be launched at a neutral or positive attitudes at moderate to high speed. Additional applicable surfaces include flaps, elevators, ailerons, elevons, rudders, air brakes, and canard trim. Enjoy!
