@dubbleyew eight:

interesting your thoughts regarding the true importance of the slisptream itself, but then a question rises in my mind... Do you think that the force exerted by that spiraling flow, and the way it hits some aircraft surfaces asymmetrically, like the low section of the left wing, the tail fin and rudder, etc... should not be considered as opposing the rolling moment due to torque only ( this because there will always be yaw-induced roll if the pilot does not take action to center the ball and eliminate the sideslip... ) ?

Since I thought that that slipstream hitting the lower section of the left wing and also the vertical fin, above the CoG, would account for a right rolling moment, and thus oppose the torque-based left rolling moment, that would "kill" my theory :-/
