Trapezium Paper Airplane

Trapezium Paper Airplane main image

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.

Trapezium Paper Airplane Folding Instructions

  • DIG. 1 diagram
    1

    Fold your sheet of A4 paper along the diagonal lines shown in DIG. 1

  • DIG. 2 diagram
    2

    You should get the shape shown in DIG. 2

  • DIG. 3 diagram
    3

    Open it out to give DIG. 3 and fold along the dotted line shown

  • DIG. 4 diagram
    4

    Push in from the two points labelled A in DIG. 3 to give the shape in DIG. 4.

  • DIG. 5 diagram
    5

    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.

  • DIG. 6 diagram
    6

    This should give you the form in DIG. 6. Again now fold along the dotted line which gives DIG. 7

  • DIG. 7 diagram
    7

    Fold along the two dotted lines in DIG. 7 again this is just bringing in the two top flaps.

  • DIG. 8 diagram
    8

    This should give you the form in DIG. 8

  • DIG. 9 diagram
    9

    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

  • DIG. 10 diagram
    10

    You should be left with a piece of paper looking like DIG. 10

  • DIG. 11 diagram
    11

    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.

Trapezium Paper Airplane Flying

This plane flies well indoors but is useless outdoors as the slightest breeze will make it crash. Hold it very near its shorter edge (the front) underneath the plane. Throw with a pushing motion or overarm so that when you let go it will be level or very slightly tilted downwards. You should find that this plane will glide very slowly for quite a long distance indoors.
