These radio-controlled helicopters are small enough to fit in the palm of your hand. The choppers come in a matched pair that can run on different frequencies, so you can have mini-dogfights with your friends.
Pressing a button on the remote can fire an invisible IR beam at your opponent’s helicopter, making it start to spin out of control. A second shot makes your enemy lose some power, and one more deadly shot kills power altogether, sending their copter plummeting to the ground.
You can grab a pair of the dueling mini helicopters from ThinkGeek for $49.99.
