The blades on a helicopter are called rotor blades. They are attached to the rotor mast and rotate to provide lift and control for the helicopter.

Yes you can fly a helicopter by using Bluetooth function on your smart phone. There are numerous toy helicopters which are compatible with Bluetooth function.
A stout round pole used as a ship's mast is called a "mast." It serves as the vertical structure to support sails and rigging, playing a crucial role in the vessel's navigation and propulsion. Depending on its height and function, masts can be categorized into different types, such as main mast, fore mast, and mizzen mast.
The thing that spins at the top of a helicopter is called the rotor blade. It provides the lift necessary for the helicopter to take off and stay in flight. The rotor blades are attached to the main rotor mast and are powered by the engine.
Mast cells release histamine during allergic reactions. The function of mast cells is to detect foreign substances in the body and initiate an immune response. Mast cells are a type of white blood cell found in tissues throughout the body.
this happens in respect generally for something very bad that has append. i.e. assassination, mayor or Governor dies etc. i believe last year a helicopter got shot down in Iraq and the flag was at half mast for about 2 weeks.
Fore-mast: the first mast, or the mast fore of the main-mast.Main-mast: the tallest mast, usually located near the center of the ship.Mizzen-mast: the third mast, or the mast immediately aft of the main-mast.(information from wikipedia)
To counteract the force of torque created by the main rotor. If not for that tail rotor, the torque would cause the helicopter to spin continuously around.
Flying a helicopter is a delicate balance of Rotor RPM and Rotor Torque. Too little RPM and it would lose lift. Too much RPM, then the centrifugal forces could damage the rotor blades. When the pilot adds Collective input to climb, the Rotor Torque could be exceeded and result in failure of the mast. Each flight restriction was based upon the design of the helicopter's mast, blades and grip. Also, if the RPMs are too high the tips of the blade will hit the sound barrier and vibrate out of control. A helicopter with a blade length of 30 ft (radius) will only have to be spinning at around 330 RPMs to reach the sound barrier.
An autogyro looks like a helicopter with a rotor blade on the top of the fuselage but it also has another propeller in back to push it. The autogyro uses the air passing UP through the rotor blade to turn the main rotor blade and give it LIFT. So it needs something to provide THRUST to propel it forward. An autogyro can NOT take off vertically and go straight up. Instead it must have a take-off roll to get it flying. The main rotor of a helicopter is more complicated and it produces both LIFT and THRUST. Their controls are more complicated and the loads on the blades and blade attachments and the rotor Mast. The Autogyro's blades turns due to air passing through it just like a maple seed "flys" with its single wing as it falls from the tree. Since the main rotor of the Autogyro does not produce a vertical Lift, that means the Mast of the rotor does not carry a torque load. The Mast only supports the weight of the Autogyro. Whereas, the Mast of the Helicopter is experiencing Torque loads and Bending loads(for some types of helicopters) as well as Tension forces by the weight of the helicopter.
