Drones are all the rage right now, and this is the
Atom RC Mini Drone. Its rotors are just 1.25 inches long, and it'll be just as hard to spot if you fly it at the right height.
It weighs half an ounce and even novice pilots can fly these fellas.
It has a full infrared remote, and a full charge keeps it in the air for four minutes with a range of 100feet.
