now how simple would it be to plop it across our little fleet?

I've found it works on vehicles (wheels) and Ordinance (experiment with parafrags as flares - which is how i discovered it CF = campfire object). Someone with a better knowledge of AC mats should be able to tell if its possible theres must be some input for RPM too as thats modelled in standard disc - [generator] section perhaps ?, though I suspect the prop disc is some form of ".txl" animation list.
