Depending on what you like to use for specific fuel consumption, horsepower and weight of gasoline, the math goes something like this....
sfc = .432 VERY TOUGH to achieve *CRUISE AVERAGE*
X horsepower = 71.5 65% of 110 hp ?
----
30.888 lbs of fuel/hour
or 5.148 gal/hour MIN (30.888 divided by 6 lbs/gal)
P.S. Prop pitch is not a factor
