Any clues on what could be doing this effect??Water wash and spay appear in mid helicopter instead of appearing at sea level, same on dust sray.Could it be any overwritten file during add on instalation?Anyone else had this problem also?

I suppose you're using the rotor_fx2 pack by Mark Luzzi?I suggest you download my updated version - it should work. Get it here: http://library.avsim.net/search.php?Search...=Root&Go=SearchHave fun!-Daniel
