For a quality answer, take a look at the Bell UH-1 Iroquois website.

The best helicopter for what purpose? If you want to take 11 infantry soldiers into combat and support them during the fight, the Hind is a good helicopter. If you want to dry cherry trees, it's too big, takes too much fuel and costs too much.
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.
time for an helicopter to takeoff varies on types and model of the helicopter it self. this is because every helicopter or aircraft have their own check list provided by the manufacturer or operator depending on operation. this check list is for the pilot to go through during start up, taxing, take off, approaching and landings. again, time for each machine to take off varies.
Take a helicopter to the other side
helicopters take alot of fuel because they are very heavy and they have to do alot of work just to stay in one place
Igor Sikorsky and Paul Cornu invented the helicopter in 1907. It was the first operating helicopter to actually take flight.
I doubt that any helicopter can fly from Antarctica to Australia.
How much oil in a 7.5L 460 engine? It is in an RV
No, a helicopter cannot take off from the moon because there is no atmosphere on the moon to generate lift for the helicopter's rotor blades. Helicopters require air to push down against to lift off the ground, and since the moon has no atmosphere, a helicopter would not be able to take off.
Depends on flight conditions, elevation, loads, if the engine is running and warmed up etc. but usually it's a matter of seconds.
