FS2002 Helicopter Dynamic Rotor Sound. This gauge is an on/off switch that when on provides a dynamic rotor sound that changes with the helicopter engines output so you can hear acceleration and deceleration in helicopter engines, instead of that constant plain sound. Designed by Brian Kostick for FS98 but works perfectly well in FS2000 and FS2002. Instructions for FS2002 installation by Alejandro Villa. 450 Kb
