  • Cut out a strip of paper about 90 X 15 mm.
  • With some scissors make a cut down half way down the middle of the strip.
  • Make two small cuts, one-third of the way across the strip about 10mm below the end of the long cut.
  • Fold the flaps of paper below the two small cuts over the middle section.
  • Fold or twist a small point to the bottom of the helicopter.
  • Fold the wings down at an angle to the body of the helicopter.
  • Straighten the wings back out so that the angle upwards by 20 or 30 degrees.

Experiment with the size of the helicopters. Change their wing sizes and pitch. Big wings make the helicopter spin and fall slowly. Small wings make the helicopter spin and fall rapidly. Find out what are the fastest and slowest helicopters you can build.
