Build your own Flying Flat Fish!¶
You can build your own sample using the parts set attached.
You may use bamboo rods or balsa sticks instead of carbon rods if it was difficult for you to find carbon rods.
I omitted a tail fin for weight reduction, so it woulld be a ‘flapping body’, rather than a ‘flapping tai fin flyer’…
Comparison of materials:¶
| Material | Phisical property | Availability | Cost |
| Carbon rod | Very light and strong 1.3 grams/m(1 mm dia.) |
Internet shop | High (5 US$/m) |
| Bamboo rod | Heavier 2.5 grams/m(1.8 mm dia.) |
Local hobby shop | Very low (0.2 US$/m) |
| Balsa stick | Light as carbon, but fragile 1.5 grams/m(2 mm sq.) |
Local hobby shop | Low (0.5 US$/m) |

Step by step assembly:¶
All plastic parts ,balsa sticks and bamboo rods are press-fitted.
In case fits were loose, secure them with instant glue.
In case fits were too tight, enlarge holes of the plastic parts using drill blades.
To attache wing surfaces to the skelton, use thin strips of double-sided tape or pressure sensitive adhesives.
