The engine turns the rotor through a transmission.
The engine is driving a transmission which turns the rotor
It's main rotor, tail rotor makes the helicopter to move which is powered by it's engine. These are the major parts of a helicopter
The rotor turns on top of a vertical shaft from the transmission
The main rotor is tilted forward.

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.

it depends. sometimes they make the helicopter turn. On models when they are facing up like the main rotor, they propell it forward so the gyro can fall to one side and lean the chopper forward. The major purpose of the back rotor is to counteract the torque of the main rotor. On helicopters with a single top rotor, if there were no back rotor, the torque would cause the helicopter to spin around as soon as it lifted off the ground.
