Hello,
You can download the FAA flight manual directly on Schweizer's website. I would be happy to provide a link, but I am not yet allowed to.
So on schweizerrsg dot com, go to publications / flight manuals in the menu. Scroll down to see the downloads and type "flight" in the search field. You should find it right away.
Mod note:

There is a cost for the pdf download.
