On further review, in addition to te conventional "P" factor, the obvious "torque effect" tries to roll the plane in the direction opposite of prop rotation. The wing leveling input adds adverse yaw, and that also looks like "P" factor.

Ed,
What you are saying reflects what I've read also - however Tracy's experience with the difference between the 2.17 and the 2.85 suggests that there is also the centrifugal forces of prop + rotor direction to contend with, as Tracy required full R rudder to maintain directional control with the 2.85, whereas with the 2.17, it wasn't anywhere near as difficult - so I'm led to believe.
If it were just the wind from the prop corkscrewing around the fuselage until it hit the rudder, the  L and R turning props would give a similar response in intensity. This wasn't the case, it would seem.
