COMMENTS:
         Some differences between a 4-stroke and a 2-stroke engine:
            A 4-stroke is quieter
            A 4-stroke gets better fuel economy
            A 2-stroke generates more RPM (11,000-13,000 rpm with prop
                while 4-strokes rev to around 9,500 RPM)
            A 4-stroke generates much more torque and will swing a larger prop
            A 4-stroke has a realistic sound (It sounds like a REAL airplane)
