Instructables
The Hoverfly and Hurricane paper helicopters I made previously each performed excellently and were very well received by the Instructables community. To give aviators who liked those birds more amusement, I decided to make another. The Tornado is a paper helicopter with five rotors, designed as the "middle size" chopper--smaller than the Hurricane, larger than the Hoverfly.

Like the Hurricane, the Tornado is among a small group of paper aircraft that qualify as "paper helicopters" not of the traditional two blade design. Because of the Hurricane's great performance and original design, it was the conceptual basis for this project's layout.

Like the previous helicopters, the Tornado 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
TAA USAF Designation: HD227-1

Step 1: Materials

Picture of Materials
Required:
1 Piece of 8 by 10.5 inch graph paper
Tape
Scissors
Pencil
Ruler

Step 2: Begin Construction

Begin making your Tornado by marking out a box of 10 by 10 boxes, with a 1 by 2 additional outcropping on a single sheet of graph paper. At the top, mark a solid line 6 boxes in length, every 2 boxes from the corners of the main box. From this line, mark a dotted line that stretches from the side of the boxes to the other, including the outcropping. Below the vertical lines intersection with the horizontal line, extend them as dotted lines.

Your Tornado 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

Step 3: Making The Rotors And Fuselage Folding

Cut along the solid lines you made previously. These will complete the rotors themselves. Once you've cut each of them accordingly, fold along the dotted lines at the bottom of the fuselage. When this is done, fold along the vertical dotted lines. After this, fold the rotors down along the horizontal dotted line below them. After this is completed, your Tornado should appear as it does in the last photograph.

I would gladly, but I still lack that capability. :(
I can't help but notice that this is a reoccuring response. I was just wondering if you might need somebody to make a video version of your instructibles? If you do I would gladly voulenteer to do so. P.S. I am totally likeing this new addition to your paper helicopters. I was wondering also if you could work on another plane that is a complete trick/stunt plane. What i mean is that i want to make a plane that doesn't fly straight, rather a plane that does circles, loops, or dives.
Hey there!
I'd like to point out, that the maker here published his/her work under the Attribution Non-commercial Share Alike license.
Therefore, if you'd like to make a video version of this Instructable, you can do so! Just mention his name in it to give him credit.
Yes, unfortunately, it has been repeated many times over. Although I have given thought to asking other makers to post videos of my aircraft if it is possible, I have never pursued it. I'm quite glad to hear that the Tornado is well received.

I believe you will also like to hear one current project is to design a new stunt plane. Until its completion however, you may wish to check out the existing stunt aircraft, the SkySpectre and the Spirit.
I have made the SkySpectre before, but the thing is, it doesn't tell you how to throw it in a manner that will present stunts to the flier. Also, I do have the ability to make videos for you, i have an omnigrid mat, lighting, and the ability to make 30+ planes you have made by memory. So if you want me to start making videos, just ask.
