Just picked up a Micro X Copter at a mall kiosk for $30. Seriously cute little bugger. Amazing to see anything like a remote controlled device flitting around a home living room with no damage to itself or anything else.
It's actually infrared controlled, not radio, with two control toggles: one up and down, one left and right. Plus a trim control.
The transmitter uses six AA batteries which also charge the helicopter and its built-in Li-poly battery to provide 5 to 6 minutes of flight after 20 to 30 minutes of charge.
As with all products, be sure to read the entire instruction sheet before doing anything with the Micro X Copter. For example, although the frequency switch looks moveable, it ISN'T.
The bottom of the box shows choppers with red accent use A, yellow B, and blue C. So you could have three different color copters flying in the same area without interfering with each other.
Rather than describing more here, check out some of the many posts on Google. For Aces High and MS Flight Simulator veterans, Micro X Copter is easy to fly and not easy to master.
After all, it's for (do you believe this?) ages THREE and up! So says the box, although the very small print instructions inside specify: "Never allow young children to use this product."
