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. If the control stick for the tail/pitch
function (also see figure 1, item 13) 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 its vertical axis (rotor shaft).
If the control stick for the tail/pitch function is moved to the left, the tail rotor speed is decreased and the helicopter
fuselage tip turns to the left.
If the control stick for the tail/pitch function is moved to the right, the tail rotor speed is increased and the fuselage tip
turns 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 13). Use the
right control stick for control of the nod/roll function (also see figure 1, item 5).
If the stick 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.
