This is how to set an idle value of 15%:
1. Select the IDLE-UP control, then the TRAVEL
option
Starting from the operating screen press x x x
to move to the menu for the transmitter control
options. Select the IDLE-UP control using q/n
or the Digi-adjustor.
Now open the Options field by pressing b and
search for TRAVEL.
2. Open the TRAVEL adjust field
Pressing the w button opens the field.
3. Select the correct end
Assuming that you want the motor to idle when
the idle-up slider is at the rear end-stop (towards
you), then you must move the slider to this posi-
tion in order to adjust travel.
The screen should now look like this:
2: Hover 1450
CONTR F :IDLE-UP Ä
;TRAVEL
[ - 70%_
The [ symbol indicates that you have selected
the rear half of the control’s travel for travel ad-
justment.
You can now set your chosen idle value using
the q/n buttons or the Digi-adjustor.
Press k k to return to the operating screen and
store the new setting.
'' TIP:
The flight mode display „2: Hover1450“ in the top line
is intended to remind you that the setting in this menu
only applies to this one flight mode!
This is the procedure for
setting the throttle to „run up slowly“:
This is no problem with the new SLOW option for the
IDLE-UP transmitter control.
1. Select the IDLE-UP transmitter control and
the SLOW option.
Starting from the operating screen move to the
transmitter control options menu by pressing x
x x. Select the control IDLE-UP using the
q/n buttons or the Digi-adjustor.
Now open the Options field with the b button
and look for SLOW.
2. Open the adjust fields for SLOW (g or w)
The times for the motor running up and running
down can be adjusted separately.

'' TIP:
The top line of the screen is blank. This indicates that
the adjustment applies to all flight modes.
How to „expand“ the low-speed range
for idle-up:
You can use the CENTRE option for the IDLE-UP
control to effect this improvement. Offset the centre
to, say, -30%, then the first half of the control’s travel
affects the range from -70% (that is the control travel
which we have already set - see above) and -30%.
Here is another diagram to make things clearer:
You can immediately see that the top half of the
transmitter control’s travel has more than three times
as much effect as the bottom half.
This allows you to adjust the low throttle range setting
for starting the motor very accurately.
The top range then simply releases the travel for the
throttle curve.
