1.3. Hovering is difficult to learn

Eventually, something will "click" inside your head, and you will "get it". For some people, this occurs all of a sudden and everything makes sense. For other people it seems to be a more gradual process.

Basically, helicopters suck horribly. Then you get your first hover, and it's an incredible headrush, and you're psyched for a whole week, and you're hooked. :)
