Column 3 “cent.”
The servo midpoint (center) setting is intended for
adapting a non-standard servo (a servo whose mid-
point position does not correspond to a pulse length
of 1.5 ms, i. e. 1500 µs), as well as for minor adjust-
ments, e. g. for the fine tuning of the neutral position
of model rudders.
Independent of trim levers and any mixer settings,
the neutral point can be shifted in a range of -125 to
+125 % within a maximum servo travel of ±150 %.
Independent of all other trim and mixer settings, this
setting is always based directly on the respective
servo.
Note that extreme offsets of
the neutral point can lead
to one-sided restrictions of
servo travel because over-
all travel is limited by both
electronic and mechanical
aspects to a maximum of
±150 %.
A simultaneous tap on the

or

keys of the right
four-way button (CLEAR)
will reset the entry field value displayed in inverse
video back to “0 %”.
lumn then, if desired, move the respective control
out of its midpoint to make an asymmetric setting.
3. Briefly tap the center SET key of the right four-
way button. The corresponding input field is shown
highlighted.
4. Use the selection keys of the right four-way button
to set the desired value.
5. Briefly tap the center SET key of the right four-way
button to complete data entry.
6. A simultaneous tap on the

or

keys of
the right four-way button (CLEAR) will any setting
made back to its respective default value.
Important:
Servo designation numerals are based on the respec-
tive receiver outputs to which they are connected,
provided that no swapping of transmitter and/or
receiver outputs has been specified. This means that
even a change of stick mode will not effect the num-
bering of servos.
Column 2 “rev”
The direction in which a servo turns is adapted to the
practical reality of the given model so that the assem-
bly of control rods and joints do not need to accom-
modate a specific servo rotation direction. Rotation
direction is symbolized by the “=>” and “<=” character
combinations. Servo rotation direction must be speci-
fied before making settings for the options which
follow below.
A simultaneous tap on the

or

keys of the
right four-way button (CLEAR) will reset rotation
direction back to “=>”.
This option is available as standard on
both transmitter types.
Use the

selection keys on the left or
right four-way button to select the »Servo

This menu is used to set the direction, neutralization,
travel and limit parameters for a given selected servo
exclusively. Begin setting servo parameters in the left
column.
Basic procedure:
1. Select the desired servo, 1 … 8 or 1 … 12, with
the

selection keys of the left or right four-way
button.
2. If necessary, use the

selection keys of the left
or right four-way button to reach the desired co-
