Ok. So i get it now , correct me if I am wrong.
Engine torque rotates the propeller & propeller torque opposes this rotation and creates a torque in the opposite direction. I.e. If the engine torque rotates the propeller clockwise the propeller torque will tend to rotate it anticlockwise.
Both these torques are balanced out for normal operating conditions.
A 3D perspective of how the torque's are acting on all blades of the propeller, is kind of hard to decipher.
But thanks I get it now.
