1. One 8.5" by 11" piece of paper
Step 2: Cut
First, you will need to cut a strip of paper 1.5" by 5" as in picture 1 and 2.
Step 3: Cuts and Folds
Now that you have cut the piece of paper to length, it's time for the next step. Cut on the solid lines and fold on the dotted. Fold A forwards, and B backwards. Fold both C and D inwards. Also, fold E upwards for wieght at the bottom. When you are done, it should look like picture 2.
Step 4: Wanna Go Farther
The blades on the helicopter should be big when your done, but if you want to make it spin faster cut the blades thinner like in picture 2.
Thanks for looking. Hope you had as much fun as I did.
