Flying Ship? (This is not a model request)

[RyuukiGeniusX]

I'm trying to make a map for Obsidian Conflict in which you can control a space ship using game_ui and logic_case entities. However as I have found, func_movelinears have bugs when parenting, so I figured I could possibly use thrusters, but I have no way of making the ship fly. Is there a way to do this?

By fly I mean have the ship have zero gravity.
