I have set my rudder expo to 30 and that seems pretty decent. Slowed it down nicely. I also use one of @J Dot's awesome plug-n-play yaw switches. Between the switch & changes to the expo settings it will yaw super slow.
I was referring to my P3 but wasn't very clear about that. Sorry, I am not sure if the P2V+ does or not. I have the yaw switch on my P2 Zen too. Works the same way, and I will occasionally unscrew the left stick a little bit. You can make the yaw switch yourself if you are crafty like that.Is there expo on the P2V+???
I thought it was on the P3 range. Also, you can now drop the rudder settings down to 0.20
