Almost all paper helicopters are made to spin in the air while flying. Making a realistic paper helicopter, however, means constructing the rotors in a way that they rotate similarly to actual helicopters. You will need several tools to construct a paper creation with the consistency and autorotation seen on real propellers. The process does not take long and, constructed properly, you will have your paper helicopter flying in no time.
Cut a rectangle out of 8.5-by-11-inch copy paper. The rectangle should measure 6 inches long by 2 inches wide.
Fold the rectangle in half. The middle crease should be between both long edges.
Cut a straight line down the crease. Cut one-third of the way down the paper.
Fold the left-side piece of the cut to the front. Fold the right-side piece to the back. These are your rotors.
Cut two horizontal slivers 1-inch below the rotor folds on both the left-side and right-side of the sheet.
Fold the bottom half of the sheet up to meet this mark. Slide a paper clip into place to hold the bottom fold together. The paper clip is added to create additional body weight.
Hold the paper helicopter in the air and let it go. The rotors will spin, realistically, as the paper helicopter swoops down to the ground.
