Proto-X Quadcopterhttp://www.estesrockets.com/helis-quads/quadcopters/004606-proto-x Description

Meet the Proto-X. Not only is it the world's smallest quadcopter, it's also one of the world's lightest multi-rotor helis!
The 1.8" x 1.8" Proto-X is tiny, ideal for indoor flying — and it weighs only four-tenths of an ounce. Bright, built-in LEDs make it easy to see the Proto-X in low-light conditions.
A 2.4GHz radio not only allows for interference-free flight — it makes it easy for multiple Proto-X helis to fly at once. A 3.7V 100mAh LiPo battery, USB charge cord and spare rotor blades are also included in the ready-to-fly package. All you need to add are two "AAA" batteries!
