FPS Vs Animations/Aircraft parameters

GuysI have been working on helicopter systems for quite some time, to which I posted this at Hovercontrol.: http://69.44.154.34/cgi-bin/ib3/ikonboard....t=ST&f=1&t=5368It seems to me that the RRPM (Rotor Speed) of a helicopter is directly influenced by the FPS, making it very difficult to program accurate system parameters if the RRPM (NR) is changed when FPS changes. Have you guys run across similar problems in your work, and if so how did you get around it?Steve
