there's lot of things like that out there,they dont cost alot,30-50 bucks,and they fly for 10 minutes, recharge time is between 20-30 minutes,uses infrared,most of the times there 2 channels so you and your friend could fly two helicopters without disturbing each other signal,the weight about 10 grams,and the shell made from foam,so its easy to made a new one,i found an apache picco z,a cool toy...
