Can anyone please see why my rocket is tipping off the moment I take off? I just cannot figure out what I am doing wrong. Now, I do realise that payload area is kind of big, but I need it like that. How do I counteract?

Thank you for all the answers. I have thought that decouplers on the both parts would make things easier... After removing one, from the rover, and doing something with re root gizmo (I still don't understand how re rooting is supposed to work) I have managed to merge the crafts. Well, for some reason rover merged upside down, but I rotated it.

Hi. I have a plane and a rover. Both have a radial de-coupler. How do I merge them?
