Are you talking about the 1/72 or 1/48 version?
The Eurocopter site (http://www.eurocopter.com/) hosts many pictures and diagrams. You can see these under the product session or the media gallery (under The Group>Medias Corner>Photos Gallery). See for example http://www.eurocopter.com/site/FO/scripts/siteFO_contenu.php?mode=&lang=EN&noeu_id=95&page_id=49
For the 1/48 version, I think the Italeri, Revell, and Heller versions are pretty much the same. They're for protoypes. I am toying with the idea of building an Australian version of the helicopter (there is an Australian firm offering the proper decals, and they're periodically available on EBay). I have no experience with the 1/72 version.
