Character rotation Angular damping

for multiplayer VR I have a character based on the 3rd person example, but I’ve hacked it around so its more like a submarine. Im using the 3rd person example character because I have not been able to replicate properly a Pawn tpye blueprint. My question is how do i get the rotation to have a bit more angular drag? (on the 'Add Controller Yaw input) I can do it on the pawn with the Capsule Physics but this breaks the 3rd Person character movement.
Any clues thanks.
