I've been trying to work down my squawk list, with the top item being the rudder/nosewheel alignment.

I assembled a simple laser pointer alignment tool and started working on the issue.

My alignment tool ready to go.

Taped to the sides of the tire and pointing down.

I dropped a plumb bob down from the tip of the prop spinner and marked it.  The rudder is perfectly straight in the back and you can see that the nose wheel is a bit to the left.  I loosened the jam nuts on the pushrods near the wheel but will need help loosening the ones inside.  It's just too tight in there for me to hold the pushrod and loosen the jam nut.  So, I'll need someone outside holding the pushrod while I loosen the jam nut.  I honestly don't know how anybody bigger than me can get under the panel at all.  Once the stick is installed, it's crazy tight under there.

I installed the plug that comes with the OptiMate charger so it'll be easy to plug it in whenever I need to (e.g. updating SW takes a long time, so you can just plug in the charger when it's doing that - it has a special mode for just that task).

Went over to the hangar tonight to check the alignment between the rudder and nosewheel and they definitely seem off a bit.

While the rudder shows a bit right (this is just how it ended up when I pushed it back)...

...the nosewheel shows a bit left...  At least eyeballing it with the towbar attached.  This means if the rudder were straight, the nosewheel would be even more left and pulling the nose left - hence the need for heavy right rudder in flight.  I may need help to do this, but the next chance I get I'll lift the nose (maybe not necessary) so I can straighten the rudder then I'll use some attached laser pointers to see how the nosewheel points.  Then I'll adjust the nosewheel pushrods to get it perfectly straight.  I didn't do any of the rigging - otherwise, it would have already been perfect... ;-)

 I've been continuing to address some of the squawks for the plane.  This weekend I added a rudder trim tab, updated avionics databases, and tweaked the left flap a bit more (still a slight left roll, so I brought that flap down a bit more).

I saw this video on testing various spray can primers for aluminum, so I picked it up at the local ACE Hardware (how convenient!).  If I had known about this when I started the project, I probably would have gone with this vs. the Cortec primer, since that was so hard to obtain.

A few coats of that and it was ready (I got the rudder trim tab dimensions from BobZ).  20cm long x 4.5cm wide, with the bend at 1.5cm.

BobZ recommended this tape for attaching it.

Two strips of that (I couldn't find 1/2" wide of that exact product) and it was ready to attach.

That tape is crazy strong!  Should fly this week, so we'll see if that works to alleviate the right rudder needed at cruise.  After that, I'll paint it the matching red.

Updating all my databases!  Very easy!
