I am a bit confused by terms used in side thrust discussions. Some say a model plane tends to veers to the left as a result of engine torque, some say torque has nothing to do with it, it is because the stream of air behind the prop is rotating clockwise, the rudder and vertical fin is normally above the thrust line, so the spiral of air will push it to the right. In most trimming charts it is said that if the plane veers left ad right thrust, to me thrust is the hi pressure stream behind the prop, so if you turn the engine to the right to prevent it from veering to the left, you are adding left thrust not right thrust ? The same applies to up and down thrust.
