This design is unconventional Stealth but works

1. Start with a plane sheet of A4 paper DIG. 1 .

   DIG. 4
   
   
5. Fold down a flap at the top right corner to give you DIG. 5 .
   
   DIG. 5
   
   
6. Attach sticky tape at the points shown in DIG. 6.

7. Now cut along the two dotted lines in DIG. 7 and fold along the solid lines to give the plane at the top of the page. Try stapling at the front to give more weight or taping the two wings together in the middle to make it fly better. I find that experimenting with this plane can make it fly really well.
