How small can these tiny radio-controlled helicopters get? This one's palm-sized, and it has a color cycling multicolor LED to make sure aircraft in the area are alerted to its miniscule presence.

This one looks like it's an even smaller version of the Picco Z helicopter we tested late last year. The prices on these babies get lower all the time—this one's just under $30. Take the jump to see a video of this latest micro-chopper in action.

These pint-sized flyers are difficult to control, but with a few hours of practice you can get the hang of it.
