Enabling physics disables controls

Hey guys, I’m relatively new to the Unreal Engine. I’ve been following a tutorial online on setting up a tank. Everything was going relatively smoothly up unto the point that physics were enabled. When i enable physics, I lose control of my pawn and I end up with a free camera. When I disable physics, I regain control of my pawn and the camera goes back to where I had set it. I’m sure I’m missing something simple, but I must have missed it in my reading of the documentation. Any help would be greatly appreciated.
