Counterclockwise.
counterclockwise
Clockwise.
counterclockwise
By reducing or increasing the rate of turn of the tail rotor, depending on which direction you want to turn.
Clockwise.
Turn it to the opposite direction that the rotor rotates.
The distributor doesn't turn, the rotor inside turns clockwise.

Counter clockwise.
By adjusting the speed of tail rotor, which points to the side, the pilot can turn the helicopter in flight. The main upper rotor actually plays only a minor part in making helicopter turn. The part supplying most of the control is the tail rotor. Because the main rotor is spinning in one direction, without a tail rotor, the body of the helicopter would spin around in circles in the opposite direction. The reason for this is explained in the first part of Newton's third law of motion: for every action there is an equal and opposite action. The torque generated to make the rotor turn also exerts torque on the body of the helicopter "willing" it to spin the opposite direction. However, the tail rotor spins, pushing air to the side. This creates force in the opposite direction, keeping the helicopter stable. By simply adjusting the speed of the tail rotor, the helicopter can be turned in flight.
The main rotor of a helicopter is actually a set of wings that turn. They produce lift, just like the wings of an airplane. To change direction, the rotor is tilted, and the helicopter is PULLED in that direction.
Take the distributor cap off an crank the engine or turn the engine by hand clockwise and note the direction of the distributor rotor.
