Fast, long range and small, the Vengeance is a very capable dart paper airplane. Because of its small size, the Vengeance has high wing loading, making it an excellent high speed "fighter-interceptor" paper airplane.
The Vengeance was developed as a "Starfire-like" aircraft with design aspects of the Vulcan being used to improve performance. The Vengeance also uses many of the traits of the Starfire, such as the forward swept trailing edges of its wings and its delta tail. In testing, the Vengeance performed well, and more advanced models were explored, perhaps for publication at a later date if successful. Having demonstrated itself, the aircraft was noted as worthy of an instructable and publication was arranged.
TAA USAF Designation: A190-1
Step 1: Materials
1 Piece of 8.5 by 11 inch Paper
Step 2: Length and Corner Folding; Cutting the Trailing Edge
Take your paper and fold it along its length. Then pull the corners on one end and fold them into the center. Then unfold the pair and cut them away along the crease. You may then discard these pieces. Proceed to the other side and make corner folds here.
Step 3: Nose Folding
Pull the creases of the corner folds inward toward the center crease as shown. Once this is completed, pull the training edges of the corner folds inward toward the center fold. After this has been done, pull the tip of the nose down over these folds. Pull the blunt tip of the nose back to the sharp trailing edge and crease. Measure one inch back from this crease, and fold the nose forward again. Then fold along the center line again.
Step 4: Canard, Wing, Tail and Winglet Folding
Fold down the canards as shown. Measure 0.875 inches above the center fold at the trailing edge and make a mark. From this mark, fold the wings down parallel with the center fold of the aircraft. Unfold the wings after making the creases, then fold the tail up as shown. Once you have made the fold, unfold the aircraft and then pull the tail through the fuselage. Measure 0.625 inches in from the wingtip along the trailing edge of the airfoils, then fold the winglets parallel to the fuselage.
Step 5: Taping
Apply tape to the nose and other parts of the aircraft where designated. Once taping is complete, add sufficient anhedral to the wings for the winglets to touch the ground. This will complete the aircraft.
Step 6: Flight
The Vengeance is quite fast, and because of its small wing has high wing loading. Launches should be done at moderately high speed at a neutral or positive attitude. Additional applicable surfaces include flaps, elevators, ailerons, air brakes, and a trimmable rudder. Enjoy!
