welllllll, i wondered if it' work with a plane insted of a face, seams to tho the mough could be wider

EDDY, Torque is created by the engine turning, the plane wants to turn the other way, this is why my Dust turns into 8*tch when the engine cuts coz i had the trim over for full revs.
The spiral effect of propwash is something else entirely, most late WW2 fighters have the rudder off set to counter this.
as far as i'm concerned right thrust is to counter both of these to different amounts on different planes
