Rocket propulsion help

I’ve been trying to make a rocket for my game but I cant quite grasp how to move it.

I have looked around the dev forum but I’ve found nothing helpful. There was this, How do I make a Rocket - #11 by LinxyDotLua but it talks about using vectors not linear velocity.

This is what my properties for my linear velocity look like.

When I try to fly it it just glitches out. If I activate ForceLimitsEnabled it doesn’t even fly.

If somebody can tell me what’s going wrong here then I’ll be quite grateful.
