R/C Flying Shark

(Video link)

"Air Swimmers" is the collective name of these fun and cool flying, radio-controlled toys that comes in the shape of a shark and a clownfish.

Air Swimmers swim through the air with incredibly smooth and life-like motion. These amazing fish provide hours of remote control indoor fun in even the smallest of rooms (not for outdoor use). They require only four AAA batteries (one in the body, three in the controller) and have complete up, down and 360 degree turning control.
