Also, I highly recommend Bill Nichols Helo Dipping mod as well as all of the finiteless stand alone sound mods.
There are other high quality mods available at
www.subguru.com , and prior to the release of new 3-d models in LWAMI the modellers are going to release their work independantly as well, as they are two separate projects that we are combining for the community as a package to make multiplayer gaming and modding easier, as well as separately so players can make the choice of how modified they want their sim.
