I got my helicopter used and after running it a couple of times found several small things wrong with it. One of the biggest things I found was that the primer bulb on the carburetor had a pin hole in it. I also started out using premium fuel in it and soon found out that was a mistake. I am actually a begginer at all this. I can hover and gad about my yard some. I am not rushing things with this helicopter. I learned that rushing things just leads to crashes. I have a few smaller electric helicopters I started to learn on. At first I was crashing and waiting on parts allot more than what I was getting to fly. Then I got the Great Planes G3.5 simulator and that helped me allot. I got a video of my helicopter that you can see by following this link.

Like I said I am a begginer so nothing fancy here. But then everyone has to start someplace.
