Keyvalues

Rotation Speed (speed) <string>: Angular speed (units are degrees/second)
Spin up time (spinup) <string>: spin up time in seconds (also affects the rate at which speed changes happen)
System Interia Scale (inertiafactor) <float>: Make this larger if the object being driven is constrained to a set of heavier objects.
Rotation Axis (axis) <vector>: The point to the Origin of the entity whose line the rotation axis.
