Howdy... A while back I picked up Rick Piper's Foxbat and Vladimir Zhyhulskiy's Foxbat, both for FS9- I've been flying them in FSX for some time now, and I don't remember having to do much to get them to work in FSX. Vladimir's version also has float and ski versions... Hope this helps!

P.S. OOPS! I got these out of mothballs, and it appears that while Rick Piper's model works fine in FSX, Vladimir's model needs a little tweaking of the model with respect to props and glass. Funny, though, both models have no trouble with the usual prop anomaly that affects portovers. I couldn't tell you if anyone has converted them, but if not, someone should- these aircraft make for nice low-and-slow flying...
