Tail Function
By turning the main rotor clockwise (seen from the top), a torque acts on the fuselage of the helicopter to turn it coun-
terclockwise. Therefore, the tail rotor is built to counter this rotation of the fuselage even without control command
from the transmitter. If the control stick for the tail function (see figure 1, item 14) is in the centre position, the tail rotor
angle of attack is automatically high enough for the helicopter to hover stably in the air without rotating around the
vertical axis (main rotor shaft).
If the control stick is moved to the left, the tail rotor angle of attack is changed and the helicopter fuselage tip turns
to the left.
If the control stick is moved to the right, the tail rotor angle of attack is changed in the other direction and the helicopter
fuselage tip turns to the right (see figure 24).
Roll function
The roll function allows you to move your model helicopter sideways to the right and to the left (see figure 25). Use the
right control stick for control (also see figure 1, item 6).
If the stick is slightly pushed to the left, the swash plate will tip to the left and the model will drift to the left side. If you
steer to the right, the model drifts sideways to the right.
