Ah I see, and agree. I thought you were saying that the rudder yaw-roll effect reversed at -ve G.
As well as that, aileron differential reverses at -ve G and would multiply up rather than reduce adverse yaw, yet it is surprising the number of people with aerobatic models who claim the differential helps when inverted, or at zero G like keeping the plane straight in a vertical climb! People convince themselves of what they want to see!
