Barry,

I was specifically speaking of washout being required on low wing
nocals. High wing and mid wing models like the Hosler Fury do not need
it and I have that model setup to fly to the right. Some washin is
generally needed in the right wing as when wound up the torque twists
the washin out of the right wing and adds it to the left wing to counter
torque. Much like an EZB body does.

The reason washout is used for low wings is because the vertical center
of gravity is above the wing. When your models stalls, a low wing will
generally fall off to one side or another or roll over. With washout in
the tips, then when the nose comes up and a stall starts to happen the
center section stalls first but the tips keep flying. In general this
delays the full stall enough to allow the nose to drop and the model to
keep flying without rolling over to one side. In a high wing nocal, when
the nose comes up for a stall , the natural stability of the models
keeps them from rolling over (generally) as the vertical CG is below the
wing.
