h) 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 model helicopter is controlled via the two control sticks at the remote control transmitter.
The following functions are available:
Pitch Function
With the pitch function you can control the flying height of the helicopter (see figure 13). The control is effected with the
left control stick (see figure 1, item 13). To that effect, the control stick 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 fully towards you switches off the engine and the rotor stops.
If you push the control stick forward, the main rotor runs and increases the speed according to the position of the lever.
Once the control stick is in the centre position, the main rotor speed should be high enough for the helicopter to hover.
Parallel to the main rotor, the tail rotor speed is automatically controlled by a percentage.
