Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.

Why doesnt a helicopter Spin out of control?
Most helicopters have a tail rotor for stability while others (often Russian military helicopters) have two main rotors. In both cases the two rotors spin in opposite directions, in order to cancel out any torque effect of a single rotor.
What are those things that spin around called on the wind turbines?
Rotors or blades.
How does wind power generate?
The wind causes the rotors to spin which rotates the coils in the generator
The spin quantum number of an electron can be thought of as describing?
direction of electron spin
Do tornadoes always spin in the same direction?
No, most tornadoes in the northern hemisphere spin counter clockwise, while most in the southern hemisphere spin clockwise. Additionally about 0.1% of tornadoes spin in the "wrong" direction for their hemisphere.
Which way do the propeller spin on coaxial helicopters?
The two rotors spin in opposite directions.

How are planes different from helicopters?
Planes have large wings, Helicopters have rotors
Where is the rotor on an airplane?
Helicopters have rotors airplanes have propellers
Why don't helicopters have two rotors?
Some do. The CH-47 has two.
Which Helicopters have Fenestron tail rotors?
Those are the helicopters designed by Aerospatiale (which was later merged into Eurocopter). IIRC, the first model to use it was the Dauphin.
Why almost all helicopters have a small tail rotor at the back?
when the main blade rotates it creates torque and if that torque is not countered by the rear rotor the helicopter will spin out and crash. the helicopters that do not have a rear rotor have another rotor that is the same size moving in the opposite direction
What direction does a bullet spin?
Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
What has the author James B Rorke written?
James B. Rorke has written: 'Hover performance tests of full scale variable geometry rotors' -- subject(s): Rotors, Testing, Rotors (Helicopters)
Why do some helicopters have enclosed tail rotors?
An enclosed tail rotor is safer and resistant to fouling.
What is the tenth most interesting fact on helicopters?
They spin around in circles!
Why do helicopters spin around when they crash?
They do not always "crash" in this manner. although when they do, it is mainly due the instabilization of the tail prop. ============================================================ if the tail prop is not spining the rotation of the main rotor will force the helicopter to spin in the opposite direction, by air drag, the tail counterbalances this force.
