Pitch Function
With the pitch function you can control the flying height of the helicopter (see figure 11). The left control stick (also see
figure 1, item 8) is used for control. To that effect, the control stick can be moved forward and backward. Unlike the
other control functions, the lever does not keep springing back to the centre position.
Because the angle of attack of the rotor blades cannot be changed, the flying height is adjusted by speed changes of
the main rotor. Pulling the control stick fully towards you switches off the engine and the rotor stops.
If you push the control stick forward, the main rotor runs and increases the speed according to the position of the lever.
Once the control stick is in the centre position, the main rotor speed should be high enough for the helicopter to hover.
Parallel to the main rotor, the tail rotor speed is automatically controlled by a percentage.
Figure 11
Tail Function
By turning the main rotor clockwise (seen from the top), a torque acts on the fuselage of the helicopter to turn it
counterclockwise. Therefore, the tail rotor is built to counter this rotation of the fuselage. If the control stick for the tail
function (see figure 1, item 8) is in the centre position, the tail rotor speed is automatically high enough for the helicopter
to hover stably in the air without rotating around the vertical axis (rotor shaft).
If the control stick is moved to the left, the tail rotor speed is decreased and the helicopter fuselage top points to the left.
If the control stick is moved to the right, the tail rotor speed is increased and the helicopter fuselage top points to the
right.
