The helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 which is the first operational helicopter in 1936. Some Helicopters achieved limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached a large-scale production, with 131 aircraft built. Although most of the above designs have used more than one main rotor, it is the only main rotor with anti-uniluque tail rotor configuration that has become the most common helicopter configuration. Tandem Rotor helicopters are also widely used because of their higher load capacity. Coaxial Helicopters, sloping planes and composite helicopters fly today.
