Tail Function (yaw)
Since the model helicopter only has one main rotor, every speed change will cause a torque around the vertical axis
(“yaw” around the rotor shaft). The helicopter has a tail rotor for side stabilisation to compensate for this torque change.
This tail rotor is driven by a separate motor and electronically stabilised by a gyro.
To turn the model around its vertical axis (rotor shaft) (see figure 11), the tail rotor has different speeds.
The tail function is controlled with the left control lever (see figure 1, item 8). When the lever is pushed slightly to the
left, the tail rotor will slow down or stop, depending on deflection. The fuselage tip then points to the left. If you steer
towards the right, the tip of the fuselage turns to the right as well.

Roll function
The roll function allows you to move your model helicopter sideways to the right and to the left (see figure 12). For
control, use the right control lever (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.
