To build this model you will need;
String (use any string that you would associate with kite flying. I recommend thin nylon string.)
Wire and Pliers
Prestik/Blue Tac/Putty/Small coin} to use as ballast
Something to wind the string around
A windy place to fly it in
Packing/Floor insulation/other lightweight foam sheets (I used the kind used for protecting eggs when you buy a tray of 30.)
Step 1: Making the Rotors
Cut 2 small circles out of the foam. These will help reduce friction. Make a small hole in the centre of each one. Then place all the parts mentioned (and 2 beads) onto the pin to create the rotor hub. The order should be like this: 0-o-O-X-O-o----------------
If 0=pin head, o=bead, -=pin shaft, X=rotor centre.
Also cut out a shape like the one shown in the 2nd last picture. This is what the shaft will be connected to the fuselage with.
Step 2: The Fuselage and Tail
Draw and cut out a slit in the tail end for the tailplane to be placed in.
To make the tailplane, follow the same process and measure, draw, then cut out the horizontal stabilizer. It will help to keep the craft facing in the right direction. Insert it into the slot and tape in place.
Step 3: Put It All Together
Then tape it on top of the fuselage.
For the skids and ballast, I bent some wire into the shape shown below before taping it underneath the fuselage. The reason for them is that when ballast is added further out and lower down, the craft will become much more stable.
Add the ballast to the skids, it works best when placed directly below the rotor shaft.
Tape the string to the nose of the autogyro/Jeep and bend each rotor a little bit so that the leading edge is a little lower than the trailing edge.
Step 4: Take It Outside!
Also shown are some other gyroplanes I have built for free flight. They work the same way but don't need to be tethered.
