The concept for the Cyclone came around the time the Hoverfly was published because, although successful, the Hoverfly's design left much to be desired. Due to the very small size of the Hoverfly, for some time I could not figure out an alternative configuration to its two rotor design. Only after the design of the Tornado did I have a workable layout--though it would still be several months before I prototyped it. Given the recent resurgence in popularity of these paper helicopters (especially the Tornado), I decided to accelerate efforts to design a Hoverfly successor; from that came the Cyclone.
Like the previous helicopters, the Cyclone is designed for many uses, including as a research testbed for use in classrooms. Some potential experiments this aircraft could be used in include:
- Air resistance
- Wing area versus weight hangtime comparisons
- Wing area adjustment hangtime comparisons
Step 1: Materials
1 Piece of 8 by 10.5 inch graph paper
Step 2: Begin Construction
Your Cyclone should now look as pictured. Cut the airframe out along the solid outer line.
Solid lines indicate places to cut. Dotted lines indicate fold lines.
Note: 1 box = 0.25 inches
