COMMENTS

Some differences between a 4-stroke and 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-strokes sound realistic (sounds like a REAL aircraft engine)
