other control functions, the stick does not keep springing back to the centre position.
Depending on the control stick position, the angle of attack of the rotor blades changes. If the control stick is pulled all
the way to the body, the rotor blades show the maximum negative angle of attack. If the control stick is pushed all the
way to the front, the rotor blades have the maximum positive angle of attack. In parallel to this, the control stick also

If you push the control stick from the bottom position forward, the main rotor runs and increases the speed according
to the position of the stick. Once the control stick is in the centre position, the main rotor speed and the angle of attack
of the rotor blades should be high enough for the helicopter to hover. Parallel to the main rotor, the tail rotor speed is
automatically controlled by a percentage.
