Again, the RC Helicopters have been shrunk in size. The Pico Flyer is the smallest but is not publically available. The Picoz (picooz?, pico-z?) Micro RC Helicopter was the smallest. Now there is the smallest RC Helicopter which costs $79.99 and is really small 
It isnt as small as the Pico Flyer, but it still beats the record for publically available RC helicopters.
The helicopter works with 2 sets of blades which spin in opersite directions and are powered from 2 indipendent motors. The rotars can spin at various speeds giving full 360 degree precise control. It works with gyroscopic inertia which keeps the helicopter balanced and controlable.
It has a range of 50' and has 2 LED's for night time flying. The batter inside is good for about 8 minutes of flight.
