I've personally found range to be rather terrible with the 4in1 box. The box it's self is nice, and works well. Nice gyro in it. But if I go more than 15 or 20 ft it starts to glitch like crazy. But then, I also managed to snap off the tip of my transmitter (Why would they make the freakin' metal so thin!?!?) and I also managed to sever my antenna while the tail boom was in a vice grip, and had to fix it by resoldering it. Not entirely sure if that could cause some range problems. In any case, i'm a walking disaster, so uh, don't listen to me. [:-]

oops is right though, the heli is so small that you really won't want to do much more than hovering around and flying in a small area
