Hi,
I don't know where you guys have been looking, .. or not looking, .. as the case may be.
The Quickstart guide and Hi-Res manual (12Mb)
are both included with the Huey .. i.e. :\Program Files\Eagle Dynamics\DCS World\Mods\aircrafts\Uh-1H\Doc
..
DCS UH-1H QuickStart Guide EN.pdf .. and ..
DCS UH-1H Flight Manual EN.pdf
Cheers
Tom
