Hey Snowcrow,
Absolutely- The direction of rotation needs to be determined very early in the
planning stage, as it dictates the shaft/furl tube location-side in relation to
the pivot. Do the bicycle wheel experiment and spin it in the direction you want
your turbine to spin, it will precess toward the side that you will want your shaft on in relation to the pivot and conversely, away from the side that the furl tube
needs to be on. Bear in mind also that when furling in the precessional direction,
the blades move away from the tower at the (gravitational) bottom of their arc
giving you a little added clearance during severe yaw conditions.
If someones turbine is wind seeking and exhibiting curious furling behavior that
tail size/weight/length mods don't seem to give predictable results from, then chances are pretty good that their shaft/furl sides are backwards for the choice of
rotation.
-too much fun- Gus

You know, this could probable solve the infamous stator burn-out problem people have been dealing with!!!! The faster the rotation is in the wrong direction becomes, the great the force against the normal furling action!!!
