The control pressures are light enough so that trim variances with
airspeed don't require cockpit-adjustable trim.

This presumes, of course, that you've got the plane rigged to fly
level.  I added one of them afterthought-ugly trim tabs on mine after I
bought the plane from a guy who weight at least 100 pounds less than I
do.

The best option would probably be to adjust the stabilizer so that the
plane is trimmed out.  One bolt on each side holds the forward "C"
brackets to the fuselage.  The location of the hole for this bolt
adjusts the stabilizer incidence.

I've needed a rudder trim tab on my bird for four years, and I finally
put one one. Sure, it looks ugly, but it sure makes the plane nicer to
fly.

There are alternatives to the ugly tab, but I hesitate to add stuff to
the control linkages and cables themselves.  The neatest trim solutions
I've seen put wedges at the trailing edge...nothing sticks out beyond
the surface, but there's just an inconspicuous wedge mounted low on the
surface.  The only trouble is, it's hard to adjust.
