Any hobby shop that sells model airplanes should have everything you need to build Freebird 2. Ask your hobby dealer for help if necessary, because substituting materials might result in an ornithopter that won't fly.

To increase your chances of success, follow the instructions exactly. Instant glue is used except where indicated. Be careful not to get any glue in the moving parts. Even if they still move, the glue will cause friction. If any part of the model comes out wrong, fix it before continuing. Once you have built a successful ornithopter, you are ready to start trying new ideas of your own!
