PlayerController falling apart

Hello

I took default OVRPlayerController and added some functionalities that i need. I did not create any colliders except Playercapsule. My playercontroller looks like this :

Is there a way to lock the position off all children to my OVRPlayerController?

I kinda can fix it by giving Playercapsule a rigidbody component. But then if i run through an object my Playercapsule collider does not stop (somehow I get stopped as if I had a line collider in middle of my camera) me and this happens ... :
