CES 2008: Interactive Toy Concepts Unveiled M.A.V. - The World's Smallest Flying Helicopter

This teeny helicopter comes in at just 2.5" tall, less than 4" long and has a diameter of 3.5". It fits in the palm of your hand. Interactive Toy Concepts used advanced micro motor technology and patented dual rotor design to enable this Micro Aerial Vehicle (M.A.V.) to have a precise and stable flight. It will have seamless turns, ascents, descents and hovering abilities within a 20ft. range.

It has a rechargeable lithium polymer batter for 7 minutes of flying with only a 5 minute charge. That doesn't seem like a lot of time but since it's for kids 10+ I'm sure it'll be plenty with their attention spans. Expect to see it out this year for around $50.
