I used to make "real" helicopters for Sikorsky. I helped a friend re-machine a helicopter, back when they didn't have all of the auto stability built into them that they have now. In those days, plus or minus .005" of an inch meant it was garbage. I have purchased a couple of the real cheapo copters for my son when he was younger. They bssically went up and down. The counter rotary wing helicopters flew best. Of course, since the blades don't flap, or move forwards or back, once they got up to speed, all kind of problems appear.
It is amazing but you can spend $200 dollars, and if your careful, (and have a real digital proportional radio) you can get quite a nice copter.
If you went over this one, and wanted to post some pics of what you did, you would have at least one other person who would be interested.
