The Ultra's have a fully symetric airfoil, no dihedral, no washout. Traditionally, the commercial Ugly's format has modest dihedral and a semi-symetric airfoil, and I've never noticed washout on them. The original Jensen kit Phil Kraft Das Ugly Stick had fairly generous dihedral, a semi-symetric airfoil, ~3/16" washout in each tip, and used 30 degree differential aileron bellcranks.

The Ultra, although its general format is looks similar, is a less forgiving design than a commercial stick or the Kraft DasUS. The original Jensen kit Kraft design should be the most forgiving of the bunch.
