This remote controlled ornithopter--the world's smallest--was inspired by Leonardo Da Vinci's concept drawing from the late 15th century. As small as a ruby-throated hummingbird, this miniature marvel sustains flight by flapping its wings 40 times a second, not with propellers or rotors like ordinary toy aircraft. Digital proportional flight control enables smooth turns, climbs, and dives with the dual-stick remote. The ornithopter's frame is sturdy, lightweight plastic, with tear-resistant mylar covering the wings and tail. Its rechargeable lithium polymer battery provides seven minutes of flight after a five-minute charge from the controller. For indoor use only. Ages 14 and up. 1" H x 5" W x 3 1/2" L. (2 oz.)
