If you're about to begin your training for a helicopter pilot career than congratulations are in order. Learning to fly a helicopter is like trying to balance a basketball on a broom handle until the one day when everything clicks.
When you begin your training you'll have to choose a school based on cost, the instructors, and the helicopters used for training. Currently there are three helicopters used by most flight schools. They are the Robinson R-22, the Schweizer 300, and the Bell 47. Each aircraft is piston powered and each has its strengths and weaknesses.
