After 128 hrs I found the following:
I made sure the nose wheel was straight with the V-notch.
Then set the rudder pedals exactly equal ( same distance off the back of the firewall )
Drop a plumb bob off the bottom of the rudder and rig it about 1/4" to the right. It may take a little more or less but this will keep the ball centered at whatever cruise you choose. This lets the V-notch hold the rudder offset just enough to keep the ball centered.
Most of my passengers are pilots or instructors so the skid ball being not centered is a no-no even momentarily : )

Guys:
A question: If the plane is built square and the ball is not centered why does one have to go through the exercise of plumb-bob'ing the rudder instead of just putting a ground adjustable trim-tab on the rudder?

Answer: Just to make it as difficult as it can possibly be..... I have never used either a plumb bob or a trim tab on any of the planes I have built or rigged. A good eye can tell you all you need to know. Just follow the KISS system and it will fly just fine.

I tried the eye-balling method. But it is very difficult to run behind the plane and keep the head from bobbing.
