I downloaded the Just Flight P-38 for FSX. The sounds are the same as David Copely's freeware P-38's. The cockpit is far more detailed, but when you place the mouse over a hot zone you are reminded that this is actually a port over from FS9; the little window pops up and the text is garbage. This is also a frame rate hog. I normally get 23-24 fps with native FSX aircraft and 20-21 with most FS9 port overs, but this one drags me down to 15-19 fps. It's ok, but I would not pay for it unless it was truly an FSX aircraft, that means all the textures are in .dds format and the pop up text over the hot zones displays correctly.
