| REQUIREMENTS |
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 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 2-Stroke and 4-Stroke engines :
4-Strokes are quieter.
4-Strokes get better Fuel Economy
2-Strokes generate More RPM (11,000-13,000 RPM with prop
and 4-Strokes rev to around 9,500 RPM)
4-Strokes generate much more torque and will swing a larger prop.
4-Strokes have a more realistic sound, like a real aircraft engine.
The new Surpass engines (Version II and III) have more power than
their predecessors and they also have more corrosion prevention
on the inside of the crankcases.
