Build your own Flying Orinthopters from Thames and Kosmos
An ornithopter is a mechanical aircraft that flies by flapping its wings. It imitates the flapping wing of flying birds, insects, and bats.
Build four ornithopter models including a bird, bat, butterfly, and dragonfly. The wings behave like propellers to generate lift and thrust, powered by a wind-up rubber band engine. A streamlined and durable bamboo and plastic building system allows models to be light enough to fly gracefully through the air like winged animals.
