Spin Master Ornithopter is a first-of-its-kind ornithopter that flies by flapping its wings like a bird. It is powered by a real air pressure engine called the patented R.A.I.D. II, which allows it to fly distances of up to 100 yards! The Ornithopter is easy to assemble and requires no batteries. Simply pump it up and you're ready to fly. It is part plane and part bird, with cyber-mechanical styling. The Ornithopter is perfect for flying in wide open grassy areas away from other people, animals, trees, buildings, and other obstructions.
