Now you can use the right arrow keys to choose 
between three types of modulation "PPM10", "PPM18" 
and "PPM24". Pressing the center 

 button in the 

right touch pad again will complete the entry.
This choice primarily infl uences the maximum number 
of control channels which can be attached to the DSC 
(direct servo control) socket, and thus also available to 
a fl ight simulator or teacher/pupil system. This maximum 
is control channels 1 ... 5 if "PPM10" is selected, control 
channels 1 ... 9 for "PPM18" and control channels 1 ... 
12 for "PPM24".

Autorotation is that state of descending fl ight in which 
the pitch of main rotor blades are set such that the 
rotor's speed matches the natural forces of air fl owing 
through, like a windmill. This built-up energy can be 
used for "recovery" lift to brake a descent by appropriate 
blade pitch adjustment.
Autorotation is a means by which real and model 
helicopters are able to land safely in emergency 
situations, e. g. in the event of a motor failure. However, 
the prerequisite for this is a well-trained pilot familiar 
with the helicopter's characteristics. Quick reaction and 
good perceptiveness are necessary because the rotor's 
inertia can only be used once to generate recovery lift.
When this technique is evaluated during competitions, 

the motor must be switched off for autorotation. For 
training purposes it is better to keep the motor running 
at idle during autorotation.
The Autorotation switch causes a switchover to the 
autorotation fl ight phase in which control of "throttle" and 
"pitch" are separate and all mixers which have an effect 
on the throttle servo are switched off. Corresponding 
parameter settings are made in the "Helicopter mixer" 
menu (see page 178); refer also to the "Principle of the 
Auto. C1 Pos." topic which follows.
The "Autorotation" name is permanently assigned to 
phase 1 and it is included in the base screen of all 
fl ight phase dependent menus. This name can NOT 
be changed. It is only possible to assign a switch to 
this option, as described on page 52. If a switch is 
assigned, it will have absolute priority over all other 
fl ight-phase switches.

The autorotation fl ight-phase can alternatively be 
activated by a threshold point for the C1 throttle/pitch 
joystick. To set such a threshold, use the

about 50 m, try to reproduce this malfunction.

expire. After the range test is ended it should again 
respond correctly to all RC controls. If this is not 
100 % the case, do not use the system. Contact your 
area's Graupner GmbH Co. KG service partner.
Perform the range test before each fl ight and, in

doing so, simulate all servo movements which also 
take place during fl ight. The range must always be 
at 50 m on the ground in order to assure safe model 
operation.
