I can see where torque would cause an unwanted effect along the roll axis, and not the yaw axis. So, would right thrust still not help that issue? What I mean is, with the engine 180 degrees in relationship to the logitudinal axis of the fusealage, the torque reaction would be directed along the entire length of the fusealage--running from firewall out through the tail, in a straight line. Therefore, the roll reaction to the torque would be having an effect along the entire logitudinal axis.
Whereas, with right thrust built in, the axis of torque reaction would be re-directed to go not through the centerline of the aircraft, but rather to exit the aircraft somewhere along the left side of the fusealage--again, around the CofG. Would this not reduce the rolling effect of the the torque reaction?
My take, with the engine axis in line with the main axis of the airplane, and thus passing through the CG torque creates pure roll to the left. Off set the engine centerline to the right and its axis of action will now pass to the left of the CG, somewhere inboard of the wing tip. The result is that the airplane will both roll left and pitch down. Take the extreme right offset solution, the engine is now pointing 90 degrees to the centerline of the fuselage (basically pointing toward the right wingtip, like some of my landings) and the torque will cause the plane to nose down. But we will have finally eliminated it from the left rolling problem. 'course the plane won't fly this way either
In all cases torque is a constant. It can only be countered with a torque in the opposite direction. With respect to the question no amount of right offset can make engine torque effects go away, just move them someplace else.
