Lockheed Martin F-22 Raptor is the United States' new air dominance fighter. The origins of the F-22 can be traced to the early 1970s, when the U.S. Air Force began studying concepts for replacement of its F-15 air superiority fighter. This became a formal program when the service requested proposals for an Advanced Tactical Fighter (ATF) in October 1985. The F-22 is the world's first fighter to introduce all-aspect stealth, as well as supercruise-supersonic flight without afterburners.

How to manufacture F-22 Raptor

Download the drawing and print it on thick paper. (Refer to Material and Instrument.) Set up your printer for thick paper.
Cut the paper according to the thick line. Start with body of plane. Fold up as dash and dot line " _ . _ . _" , and fold down as dash line " - - - - " . Cockpit is surrounded partly in the body. After folding, open and cover back side of plane in paste or glue and re-fold. Cut out the catapulting hook. Fold air intake of engine and paste on the lower side of body. Paste nose cover at nose of body. If you will coat the plane with spray paint, paste additional nose weight at the nose of body to adjust the center of gravity.
Attach the wing on the body. Dihedral angle of main wings is 0 degree. Bend down (anhedral angle) horizontal tail wing at thin line by 7 degree. This anhedral angle is not seen in real F-22, but it is effective to avoid interference of main wings and increase stability for paper airplane flight. Paste vertical tail fin parts on the inner edge of horizontal tail wing (refer figure). Vertical tail fin is inclined out by 28 degree from vertical line. No balance weight is needed.

Adjustment
Bend front edge of main wings slightly as a bow shape to make camber. Form washout (decrease angle of incidence at wing tip) at the tip of main wings to avoid tip stall and increase stability. Bend up very slightly horizontal tail wing at front of vertical tail fin as body line for pitch adjustment. Spray paint thinly if fly outdoor.
