Great to hear about such an uneventful first flight!!  Congratulations,
Dave.  A long time coming and I feel like I've watch you build it here on
the list.  There is just no comparison to the feeling when you lift off on
your first flight - unless its after you touch down {:>).

If you do find one wing is a bit heavy, I (and others)  found that gentle
squeezing the trailing edge of the light wing's aileron can alleviate the
problem without any trim tab. This approach has been documented in some of
Van's RVator magazines and try by many.  It does work.
