This section provides information about the how’s and
why’s of the individual model helicopter functions.
This is how
the IDLE-UP function works
The IDLE-UP transmitter control includes the following
options:
• TRAVEL, variable separately for both directions
• CENTRE, variable
• SLOW, variable separately for both directions
TIP:
If you decide to change the full-throttle position for the
idle-up control, you will need to reverse the travel of
the idle-up control.
With these options you can:
z Ensure that the carburettor is opened slowly
when idle-up releases the throttle.
z Limit throttle to an idle value when idle-up is
„closed completely“.
z „Expand“ the lower part of idle-up so that finer
control of the throttle is available when you are
starting the motor.
However, we would like to start by showing you how
the 352),PF throttle control for helicopters
works with the help of examples and diagrams.
In the section after that we will explain how to adjust
the individual settings.
How the throttle function works
with a helicopter when AUTO-ROTATION
is selected
The flight mode AUTO-ROTATION has maximum
priority. When you select this mode all other settings
are over-ridden by the values which have been en-
tered for this flight mode.
In AUTO-ROTATION a fixed value is passed to the
throttle servo. This fixed value can be adjusted as
follows:
1. Switch on AUTO-ROTATION
This is done in the base types by operating the
switch S04.
2. Select the transmitter control option
THROTTLE CURVE for COLLECTIVE PITCH
Starting from the operating screen you reach this
point with the button sequence . The
name of one control should now be flashing, and
you can select the control COLLECTIVE PITCH
with / or the digi-adjustor.
Now open the Options field with the button
and search for THROTTLE CURVE.
The menu should look like this:

Press the button twice and the last line will
change to:
iiiiLAUFKiWIQ.i5]
The % value is already flashing, and you can
select a suitable value using / or the digi-
adjustor.
Pressing returns you to the operating
screen from this menu.
This is how DIRECT THROTTLE works:
Direct throttle has second-highest priority after AUTO-
ROTATION.
When the direct throttle switch is in the ON position,
the throttle servo is controlled „directly“ and exclu-
sively by the transmitter control IDLE-UP. The position
of the collective pitch stick no long influences the
throttle servo.
In the base types slider F is assigned to this function.
Note:
This only works if
AUTO-ROTATION is not switched on!
The switch for DIRECT THROTTLE is also located
under the options for the COLLECTIVE PITCH trans-
mitter control.

The switch S06 is assigned to DIRECT THROTTLE in
the base types. If you set the option to ON instead of
assigning a switch, then the throttle is always con-
trolled by the IDLE-UP control (except in AUTO-
ROTATION mode).
TIP:
For electric helicopters DIRECT THROTTLE ON is the
best mode of operation.
If you set THROTTLE both as the transmitter control
and as the servo, then the link to AUTO-ROTATION is
not generated automatically, and you have to program
it specifically.
