ORNITHOPTER

An ornithopter (from Greek ornis, ornith- "bird" and pteron "wing") is an aircraft that flies by flapping its wings. Designers sought to imitate the flapping-wing flight of birds, bats, and insects. This design powered by a single dc motor, SERVO can be used for the tail. Design is intended to demonstrate the mechanism and its fluid motion. below given link for the youtube video is not my own but this model is inspired by that design
