Remote control helicopters: infrared or radio?
I'm thinking about getting one of those little remote control helicopters to tool around with at home (and work?!) and wanted to gather some thoughts on infrared- vs. radio-controlled. It seems all the cheaper choppers are infrared. I don't want to spend very much, but I also don't want the copter to crash when the infrared loses a line of sight. What kinds have you purchased and what are your thoughts on them?
