Cheerson CX-10 Nano RC UFO Quadcopter,
, I think it is the most smallest Rc quadcopter.
It is so nano that you can hardly see it when it flys away meters long.
But it is very suitable for beginners to use, it have all the functions that branded multicopters to do with 6-Axis Gyro.
With strong break-resistant ability, to operate it is so easy that you can learn to control the multicopters skill quickly.
Super-mini size, you can put it into your pocket directly with its controller.
With such low a discounted price of $18.97
, you can own a rc quadcopter without a hitch.
Anyway, i consider it is the perfect one that one would like to learn mulicopter control skills as beginners.
