How do I use the collisions of the meshes instead of a capsul component?

Hello,
I am currently working on a spaceship. This consists of several child actor components and associated actors, each of which has a static mesh.

The only way I have been able to achieve collision so far is through a capsule component in the spaceship actor. Instead, however, I would like to use the exact collision of the mesh from the child actors. How can I do that?
Alternatively, if this is not possible, how do I use a custom mesh as a collision for the spaceship?
Thanks for your answers in advance!
