FSX/P3D. That's right, as if the Milviz F-4E Phantom II couldn't possibly get any better, they went on ahead and rolled out the Advanced Series Milviz F-4E Phantom II. What does that mean exactly? Well according to MilViz they developed the Advanced Series F-4E to overcome the current limitations present within FSX and P3D such as flight dynamics and systems simulation to provide a more authentic representation of the aircraft. In quick terms, they coded much of the model outside FS to expand it's capabilities as well as enhanced the systems. There aren't too many study level military jets available in FS but this is damn close. Want the real details? Check out the source link below.
Note: The Advanced Series F-4E module is not a stand-alone add-on. It extends the functionality of the MilViz F-4E Phantom II. and as such, that aircraft is required for this release to function. It is also compatible with the existing TacPack add-on for the F-4E, but does not require it. The Advanced Series F-4E module does not function nor is it compatible with the MilViz F-4J/S. Upgrade price is $18.99 USD.
