The advanced systems on some helos are best described as bullying FS to do things it was never designed to do, unlike fixed wing, pure helo FDEs are seriously lacking in fidelity, especially the Bell turbine set up, the R-22 piston one is a little more advanced but its safe to say that a simpler glider FDE has more parameters and functions than default helo FDEs.
What some users do is to make hybrid helo FDEs, basically turbo prop planes tricked into flying like a helicopter, this does mean there very hard to set up and in some cases, unstable in sim, they dont work in FSx either very well....yet.
So in Nemeths defence, what there doing is bloody hard work and if 50% works then there onto a winner, but there can be reliability issues as you note and Alphasim sticks to the rock solid defaults with limited systems and start stop sounds, and ironically gets hammered for that almost weekly LOL.
Regarding a Hind ?, l dont know, l know of one or two further down the line but no Hind yet, its one of those that you know which ever one you pick will have the annoraks crawling from the woodwork about this antenna and that antenna LOL, in the nicest possible way of course

, l can already see it coming with the Blackhawk twins and have ordered my extra thick Nomex suit ready for release day <grin>.
