COMMENTS: Some Differences Between 4-Stroke and 2-Stroke Engines;
            4-strokes are quieter.
            4-strokes get better fuel economy.
            2-strokes generate more RPM.
            4-strokes generate more torque and will swing a larger prop.
            4-strokes have a realistic sound, like a real aircraft engine.
