The big issue in paper-planing, as far as I see it, is that all the cool-looking planes don't fly well. So I took a cool-looking plane and good-flying plane and combined them to see what would happen. The combination flies better than the original cool-looking plane, but perhaps not quite as well as the original good-flying plane. Anyway, you will need 3 sheets of normal paper, scissors, and some tape.
Step 1: Making the dart
The part of this plane that flies is a regular dart-type paper airplane. These photos should show how to make that.
Step 2: The cool-looking part
Step 3: Making the tails
Step 4: Making the wings
Wings help things fly. See pictures. This will use the third piece of paper, from which you cut your second tail. It should be a square.
