The tail rotor needs to be rotating counterclockwise. This brings the rotor blades "up" into the downwash of the main rotor.
A helicopter tail rotor serves two essential features. It provides a counteracting force to the helicopter's predominant rotor; without the sideways thrust produced by means of the tail rotor, the torque generated with the aid of the main rotor could spin the helicopter's body in the opposite direction.
The tail rotor is used to govern the heading of the helicopter even as hovering or while making hovering turns, in addition to counteracting the torque of the principal rotor. hovering turns are commonly known as “pedal turns.”
The tail rotor balances the forces generated from the main rotor and also allows the pilot to regulate the course the nostril is pointing while the chopper is hovering. Tail rotors are usually powered by way of the same driveshaft as the main rotor, letting them sync up.
