Heads up for everyone:
If you have the FSX accleration F18 Hornet for FSX and FSX:SE, you might want to google FSXBA, fsdt. The developers have completed updated the original FSX F8 Hornet for P3Dv4, as well.
They have completely overhauled the FSX Accleration F18, with updated avionics, flight dynamics etc. You can acquire the new upgrades to the F18. In order to fly the F18 in P3Dv4, you have to install the FSX acceleration Hornet. You can acquire the FSX as well. Good Luck everyone.
