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 tip points to the
left.
If the control stick is moved to the right, the tail rotor speed is increased and the helicopter fuselage tip points to the
right.
Roll function
The roll function allows you to move your model helicopter sideways to the right and to the left (see figure 12). Use the
right control stick for control (also see figure 1, item 3).
If the lever is steered slightly towards the left, the model drifts sideways to the left. If you steer to the right, the model
drifts sideways to the right.
