That's the Plettenberg Advance. I was using 2 Fury washers as a spacer (also a Hacker on behind it lol). I didn't have a prop hub as a spacer (at the time).

The flair on the rudder adds some drag (been told) and does add a feel of expo. I asked Marcelo to make me 2 rudders for the Epic, one with a huge flair and one that I thought looked about right. The huge flair rudder had too much dampening and the one that looked right, also felt right.
