Microfly is a clever propeller-driven flyer, controlled by a transmitter that also acts as a charger. It will hover or move up, down, forward and backwards to irritate your coworkers or family members. At a size of only 2 1/2 x 1 1/2 x 2 1/2-inches, it needs six 1.5V AA LR6 batteries (not included.) You can get your own Microfly for $24.95, shoot some fuzzy images, and try to convince others on YouTube you saw a UFO.
