What kind of fuel mileage do helicopters get?
user
The exact mileage depends on the model of helicopter.  The best mileage is usually obtained with mid-sized single-engine helicopters, like the Robinson R-22 and the Bell 47.  With these models, you can expect to get about 50 miles per gallon.  Larger helicopters are usually less fuel efficient, although even a large helicopter like the Sikorsky S-64 can get around 50 miles per gallon.  For a small helicopter like the Robinson R-44, you can expect to get about 30 miles per gallon.
