3. Selecting the correct side
If we assume that you want the motor to idle
when the idle-up slider is at the „back“ stop (to-
wards you), then you need to move it to this posi-
tion to be able to set the travel.
The screen should look like this:

The
|
symbol indicates that you have selected
travel adjustment for the rear half of the travel of
the idle-up control.
You can now define the idle value with / or
the digi-adjustor.
Press to return to the operating screen, and
your setting is now stored.
TIP:
The display of flight mode „2:Hover 1450“ in the top
line is intended to remind you that the setting in this
menu only applies to this one flight mode!
How to ensure that the throttle opens
gradually:
This is no problem with the new option SLOW for the
IDLE-UP control.
1. Select the IDLE-UP transmitter control and the
SLOW option.
Starting from the operating screen press
to move to the transmitter control options menu.
Then use / or the digi-adjustor to select the
transmitter control IDLE-UP.
Now press to open the Options field and
search for SLOW.
2. Open the adjust fields for SLOW ( or )
Note that you can set the transition time sepa-
rately for advancing and retarding the throttle.

TIP:
The top line in this display is empty, which means that
this setting applies to all flight modes.
How to expand the idle range for idle-up
This is possible using the CENTRE option for the
IDLE-UP transmitter control. If you offset the centre to,
say, -30%, then the first half of the control travel cov-
ers the range -70% (i.e. the travel which we set ear-
lier) to -30%.
You can immediately see that the top half of the travel
of the idle-up control has more than three times the
effect of the bottom half.
This gives you very fine control when setting the throt-
tle signal for starting the motor, i.e. in the lower idle
range. The top area then just releases the travel for
the throttle curve.
Gyro suppression
Why suppress the gyro?
We have already mentioned this in the section entitled
„V-characteristic for analogue switches“:
The gyro is designed to counteract unwanted
movements of the helicopter around the vertical
axis, but it also counteracts intentional control
commands when the pilot moves the yaw stick. If
you wish to give a yaw command, then the gyro
effect must be reduced.
This is how it’s done:
If you control the GYRO servo using an analogue
switch which has been assigned the V-characteristic
and which is controlled by the transmitter control
YAW, then gyro suppression is already set. This is
how you do it:
1. Define an analogue switch
Starting from the operating screen press
to move to the menu „Assign switches“. Press
to open the select field and then select the ana-
logue switch A1. If in your case yaw is not on
control A (left-hand stick) select A3. For the ana-
logue switch A1 the menu should look like this:
