Well, of course the torque can't be "cancelled out." If it were, then there would be no rotation of the propeller, because that is what causes the torque--rotational forces. However, this isn't a physics class. The guy isn't climbing into a jetliner and hauling hundreds of people across the coutry. Get real, and get a life. The torque of the engine definitely has something to do with the leftward yawing tendency, and placing right thrust into the firewall will help to compensate for this. This is all the explanation that a beginning RC PILOT needs.
