The following functions are available:

the two rotors.
If the control lever is in the lower position, the motors and the rotors stop. If you push the control lever upwards, the
two rotors start up and increase their speed according to the position of the lever. When the control lever reaches the
centre position, the helicopter should hover.
Figure 9
Tail Function
As the helicopter is equipped with two counter-rotating rotors, there is no torque around the yaw axis (rotor shaft).
The helicopter does not need a functional tail rotor for lateral stabilization. To allow the model to turn around the yaw
axis (rotor shaft), the two main rotors run at slightly different speeds. Depending on which one of the two main rotors
isfasterorslower,themodelturnstotheleftorright(seegure10).
Thetailfunctioniscontrolledwiththerightcontrollever(seegure1,item3).Iftheleverispushedslightlytowards
the left, the tip of the fuselage turns towards the left. If you steer towards the right, the tip of the fuselage turns likewise
towards the right.
