e) Basic Information Relevant to the Control of Model Helicopters

Before you fly your model, you should first familiarize yourself with the control possibilities open to you and thereby be
able to fly safely. The indoor helicopter is controlled with the aid of the two control sticks on the transmitter. The
following functions are available:
Pitch Function
With the pitch function you can control the flying height of the helicopter (see figure 9). For control, the left control lever
(also see figure 1, item 8) is used. It can be moved upwards from the lower position, into which it returns due to a
spring. Since the angles of attack of the rotor blades are not modifiable, setting the flying height is effected via a
common speed modification of 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
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.

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 and the model begins to turn (see figure 10). The tail
function is controlled with the right control lever (see figure 1, item 5). 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.
