Trapezium Paper Airplane
This paper airplane is all wing with a heavy nose. The structure of the nose is quite unusual but very effective. Even if thrown as hard as possible at a wall it will be undamaged. The last time I saw the first one of these I made it was flying towards the Severn estuary from the top of a tall tower in Bristol.jump to the instructions
Trapezium Paper Airplane Folding Instructions
Fold your sheet of A4 paper along the diagonal lines shown in DIG. 1
You should get the shape shown in DIG. 2
Open it out to give DIG. 3 and fold along the dotted line shown
Push in from the two points labelled A in DIG. 3 to give the shape in DIG. 4.
Now flatten out this form and fold along the dotted lines in DIG. 5. You should find you are folding in flaps created by the previous folds.
This should give you the form in DIG. 6. Again now fold along the dotted line which gives DIG. 7
Fold along the two dotted lines in DIG. 7 again this is just bringing in the two top flaps.
This should give you the form in DIG. 8
The triangular flap in the center (underneath the two flaps you just produced) should have two pockets. Tuck the flaps produced in step 7 into these pockets as shown in DIG. 9
You should be left with a piece of paper looking like DIG. 10
Now turn the plane over and fold along the lines labelled AC and BC in DIG. 11. These folds are very important if you want to produce a plane that flies absolutely level.
