Torque created by blade rotation is exerted on the helicopter's fuselage, which will spin in a counter direction unless it's neutralized. A tail rotor, which is attached to the tail boom, is how most helicopters counteract the torque created by the main rotor. The tail rotor of a Black Hawk has an 11-foot (3.35-m) blade that spins to create lateral force and stabilize the helicopter. By adjusting the pitch of the tail rotor, the pilot can turn the helicopter left or right.
