The torque on the aircraft from a pair of contra-rotating propellers effectively cancels out.

Contra-rotating propellers have been found to be between 6% and 16% more efficient than normal propellers

Butch, I have often wondered this.  Why on twin and four engine planes, do they not make the port engines spin clockwise and the starboard engines anticlock (or vise versa)?  Would think that would also balance things out.

Hi Butch,

Thank you for your reply!  This must be a fairly complex system, is it a shaft within a shaft?
