Hmm, It did not work. Apparently they were already set to the settings you provided 
I made sure to set the spring arm and the camera to relative transform and untick use pawn control rotation, but I am getting the same flip floppy camera settings.
Could it be the rotation from the export? I downloaded the model online and then opened it in max, and its base rotation was nose down. I fixed the rotation in 3ds max then exported to fbx like I normally do. I didnt have this problem when I was exporting skeletal mesh animations for the 3rd person tutorial. Very weird that I am having them here too
