Bought it to train myself, now it's a fight with the wife, and kids to fly. Great learning tool, and way cheaper to start over than to fix real heli. Does NOT work right out of the box on new computers.  Not super computer savvy, so I dug out my old computer with windows XP and it worked great. Box says compatible with windows 7 but there's a lot of extra steps so I just put it on the other computer in around 2 mins was up and flying.  You can do an internet search for the steps, it just wasn't that serious to me.
