Shhh Oleg. They don't like people talking about mods here.
Well, seeing as you've mentioned them, I'l probably just about get away with saying that they are a pig to fly well, at least to start with. So probably accurate in that regard at least. Apparently the modders struggled for months to get them to work, but they seem to handle more or less correctly, from what real chopper pilots have said. I'm sure someone will tell you where to find them, so give it a go.
