Paper Helicopter

OK! So it isn't a plane but it is a good model and when simply dropped it will stay aloft for ages and spiral down excellently.

DIG. 11
Cut along all the solid lines on the diagram to the left.
2Fold flap A forward and flap B to the back.
3Fold flaps C and D both forward along the dotted lines.
4Fold along the line E upward to give a weight at the bottom.
5Now this should look like the diagram at the top.
6You can scale up this model as much as you want. You just drop the model with the blades facing upwards and the weight at the bottom facing downwards for the best results.
