Step 4 Wings

Since the basic pincher test went well it was time to move on to the next puzzle. The wings. I knew that I wanted to use halves of a street lamp cover, but I had not decided if it was worth the trouble to make them move. The discovery of the "kneading" mechanism from a massage chair at the dump helped me make up my mind. This mechanism produced such a perfect elliptical rotation that I had to give it a try. While this saved me trouble of designing the moving parts, it presented me with the challenge of integrating it into the gas tank and connecting it to the wings.
