Hey. I have a few aircraft I want to rig to behave like the Hind, Apaches, and CF-104 currently in scorched. To do this, I set the whole heli as a GUN, right? All I need is a GUNPIVOT point, and what would be the proper place to position it?

Off the top of my head, I'd say add about 10-20% to the length of the aircraft from centre to tail and place the gunpiviot that distance below the centre. That should keep the tail from "submerging" in the ground, and also not place it too high in the air.
