Speed problems since installed FSP

[miki_x]

Hi,

I've got a serious problems isnce I installed FSP... All my installed planes reach insane speeds. For example a 737-800 reaches 250-300 Kts during
takeoff and about 600-700 Kts while in flight.
Before FSP everything was normal.
ANy suggestions for this problem?

Thanks!

Hello,

this is the firts time I hear this problem,
This appear only when you start a FsP flight or at anytime ?
Is it the last version of FsP ? legal version from this site ?

Best
