Picoo Z has just doubled the fun of R/C mini helicopters with the Tandem Z Chinook. Yes, two rotors, just like the real thing, for twice the number of high-speed crashes into walls, twice the chased-by-your-cat action. Its also got a three-channel remote control now, so you can try forward-backward moves properly—remember how tricky the original Pico Z was to fly with only up-down and left-right? Available for around US$79. [Geek Alerts]
