So will this new bird work with SP1? Specs just said FSX.

For a definitive answer, I would ask on the iFly forums if I were you.As a pure guess, I presume you don't need Acceleration or the service packs if that's what it says on the Specs, and in any case, most of what those add to FSX does not prevent things from working for add-ons that don't specifically need them.

You will need SP2.cheersJP.
