THE ORIGINAL NANO QUADCOPTER.
Meet the Proto-X, now available in six colors — black, white, red, yellow, green and purple. Not only is it the world's smallest quadcopter, but it's also one of the world's lightest quadcopters.
The 50 mm Proto-X is tiny, ideal for indoor flying — and it weighs only 11.5 g, just 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 quadcopters 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!
