Object flings with VectorForce

[Osci55]

I’m trying to make some kind of rocket which basically flies into the air.
I’m using Vector Force and it works great when I use one part but when I add more stuff to the rocket it starts flinging around the map. It probably has to do with the balance of the objects but how do I fix that?

Kinda looks like this:

Most likely to do with the force not being applied at the center of what I assume your model.
refer to this to find the center:

How to find center of a model?

Hi. I would like to find the center/middle of an object that contains folders, meshes, parts etc. I would just like to find the middle of that model. But when I click the model there is no “Position” property. Is there any way of finding the center position values of that object? Thanks. Feel free to ask more questions.
