f) 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 10). For control, the left control
lever (also see figure 1, item 8) is used.
To that effect, the control lever can be moved forward and backward. Unlike with other control functions, the lever does
not keep springing back to the centre position. Because the angles of attack of the rotor blades cannot be changed,
the flying height is adjusted by speed changes of the main rotor.
Pulling the control stick towards you switches off the motors and the rotors stop. If you push the control lever forwards,
the rotors start up and increase their speed according to the position of the lever. When the control stick reaches the
centre position, the helicopter should hover.
