Mounting animated models to a vehicle.

Hey Guys

I'm trying to find a tutorial to ,say, add an animated radar dish to a vehicle, but keep coming to a dead end. Anybody know a good resource for this? Or for adding an animated flag to a vehicle, that kind of thing.

I take it I create a radar dts as a dts of it's own, with it's own rotating animation, and add it to a mount point in script or something? A bit like a weapon.

Thanks in advance

Harvey
