Heli Rotor System

[Phlyer]

Can anyone help with this please - some time ago I found a site where I was able to get a description of the helicopter roter system - it had exploded drawings showing each part and how it worked. I lost the site when I changed my computer, does anyone have the info please.

Don't know about the webiste, but Ray's authorititive book does a pretty good job of explaining the principles of how different heli systems work.
