The idea of Inertia Thrusters is simple, you quite simply place them around your ship as if it were a normal thruster (in other words, anywhere) and it would increase the turning/rotating speed of the ship it's attached to. It would use less power, as it outputs slightly less, and the more there are, a multiplier increases slightly, this multiplier affects all inertia thruster turning speeds, regardless of being adjacent to eachother or not.
A simple idea, yet one that could make turning large ships bearable. ^_^
