The WhirlyBirds of SimCopter
Helicopters, like cars, people and cats, have both subtle and noticeable differences. Here are some specs of the helicopters available to save your city. Speeds are given in kilometers per hour (km/h) and knots (kts). Seating capacity is in addition to the pilot. Range is in kilometers and nautical miles (nm). Weight is for empty helicopter in kilograms and pounds. Rotor diameter is in meters (and in feet and inches for our friends still using the English system):
