11. General information on
controlling model helicopters
Before operating your model, you should first become familiar with its control features in order to be able to safely fly
the model. The electric helicopter is controlled using 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. It is controlled with the left control stick (see
ill. 1, pos. 7). To that effect, the control stick can be moved forward and backward without it springing back to middle
position, as is the case with the other control functions.
Completely pulling the control stick towards you switches off the motors and the rotors stop. If you push the control
stick slowly away from you, the two rotors will start up and their speed will rise as you continue to move the stick further
away. When the control stick reaches middle position, the helicopter should be hovering. The flying altitude can be
regulated either by changing the speed of the main rotor or by collective adjustment of the blades. To do so, the
swashplate is lowered by the three servos (the helicopter ascends) or raised (the helicopter descends).
