Definitely one of the most amazing and durable flying machines we have ever come across. A remote controlled helicopter that fits comfortably into the palm of your hand weighing a mere 10g. A 20 minute charge direct from the controller gives 10 minutes flight time. Its robust yet light polypropylene structure makes it easy to fly and extremely robust. Once you have mastered the Picoo Z, the more competitive amongst you may want to try challenging another two of your friends to a Picoo race or sky battle, made possible with their tri-band technology. Combine all this with an auto-stability system and precision speed; the Picoo Z is quite simply superb.
