A couple more sites that are really good, [link=http://www.helifreak.com/]Helifreak[/link] and [link=http://rc.runryder.com/helicopter/home/]Runryder[/link]. Tons and tons of reading and information to be had at those sites.
I started with a Raptor 50, no sim, and my first few hovers were knee shaking. Had to think about every little input. I'd lift it off, hover for a few seconds then set it back down and breathe. lol.
Depending on your sim, you could also try putting in some expo and that might dull down the hovering a little for you.
Have fun, it gets addicting real fast.
