As the others said, I would recommend installing HSFX 4.1. It's an easy install and works as advertised. After you get used to that you can always experiment with UP 2.0 or some of the other mod packs here. Either way, the Mustangs are much more enjoyable to fly now.

I also recomend HSFX 4.1 over UltraPack 2.0

In that most of what UltraPacks does is simply re-pacakge HSFX 4.1 into a different install pacakge, i.e. UltraPack 2.0

They are also known to make some changes to the flight models of some of the mods without consent, let alone consulting the orginal mod maker.

Which resulted in two differnt but same planes

And of the ones I have tested the UltraPack changes resulted in a less accurate Flight Model

In english the changes they made to the flight model resulted in more errors not less
