... shows what a person can do when he bothers to think out a problem a bit

.
Just one thing, though... I take it you don't use any of the major mods? The reason I ask is that I haven't been able to use sound for determining speed since I modded my game (some modder thought it would be cool to change all the ship's sounds

)... I haven't been able to figure the new RPM to speed convertions since
If anyone has info on this please share
