The gas turbine (jet engine) has an output shaft. This goes into a gearbox which drives the rotor and tail rotor. The helicopter turns by changing the pitch of the tail rotor, and so the sideways force at the end of the boom.

So the main rotor doesn't change position at all? It's all combination with the tail rotor?
The rotor to move in relation to the heli's body. "Rotate"
Like the tires of a car turn in relation to the chassis

What do you mean by change position?

How does the rotor pitch changes without the jet engine moving? I guess that's my original question but I didn't know what words to use.

Individual main rotor blade angles (pitch) are changed by the swash plate. Tilting the swash plate (cyclic input) creates more lift on one side of the rotor. Raising or lowering the swash plate (collective input) creates more or less lift.

Do you know any good websites containing information about rc helis?
