          Instructions

REQUIRES: Fuel: 5%-15% nitromethane with 18% lubricant. Synthetic, castor, or
           a synthetic/castor blend may be used.
          NOTE: Certain four-cycle fuels cannot be used due to low oil content.
           However, SOME four-cycle fuels such as the Wildcat 4-Cycle 15%
           (CATP9109) may be used because it has a 18% oil content.
           When choosing fuels for this engine, the modeler must be sure to
           select a fuel with at least a 18% lubricant content.

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
           4-stroke sound realistic (sounds like a REAL aircraft engine)
