to counteract the torque of the main rotor. when the main rotor rotates it creates drag which tries to rotate the aircraft, the tail rotor balances this. it also turns the aircraft left and right by changing the pitch. if a helicopter loses the tail rotor it will spin uncontrollably

Do the rear blades of a helicopter lift the helicopter?
NO, the main rotor does the lifting and the small rear propeller is used to stop it spinning around and help with steering it.
Where would you find a propeller shaft fitted on a vehicle?

What is the purpose of a propeller?
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law.So its mainly used to generate thrust and fly in the air. . .Sahil Kapoor.
Are rotors used to help lift a helicopter off the ground?
The rotors are used for lift and thrust on a helicopter.
Is back an adjective?
The word back can be used as an adjective, meaning "towards the rear", as an adverb, meaning "to a previous place", or as a noun, meaning "the rear of a body".
