I believe AlphaSim has a payware ( ) one, but the only freeware version I am familiar with is Vlad Zhyhulskiy's, found here for ACOF. It's an overhauled version of the 2k2 model, so it should work fine in either sim. Not sure about FSX, though.
Technically, it's neither! However I just used the general search, far easier than trawling through pages manualy. This brought up V22 hits in fixed wing and heli' sections. Not hard.
