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.jump to the instructions
Paper Helicopter Folding Instructions
Cut along all the solid lines on the diagram to the left.
Fold flap A forward and flap B to the back.
Fold flaps C and D both forward along the dotted lines.
Fold along the line E upward to give a weight at the bottom.
Now this should look like the diagram at the top.
You 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.
