If you want a one-word answer...yes!

I've modified a couple things to make it "perfect":

- Reprogrammed the autopilot xml gauge to make it behave more like the real one
- Made Michael2's EPR gauge mods
- Modified a virtual cockpit texture so that the flap handle lines up with the numbers
- Added a Nav/GPS button to the GPS window.

Other than these things, I have had zero problems with the aircraft. I'm running FSX Acceleration on Vista 64.

Be warned though, there is much less automation on this aircraft...you'll have to fly and navigate for yourself.  That's what I like about it!
