Column 3 “cent.”
The facility to offset the servo travel centre is intended
for adjusting servos whose centre setting is not stan-
dard (servo centre point at 1.5 ms), and also for slight
adjustments, e. g. when adjusting the neutral point of
a model’s control surfaces.
The neutral position can be shifted within the range
-125% to +125% of normal servo travel within the ma-
ximum servo travel of +/-150%, regardless of the trim
lever position and any mixers you have set up. The
centre setting affects the associated servo directly, re-
gardless of all other trim and mixer settings.
Pressing CLEAR resets the value to “0%”.
Column 2 “Rev”
The direction of servo rotation can be adjusted to suit
the actual installation in your model. This means that
you don’t need to concern yourself with servo direc-
tions when installing the mechanical linkages in the
model, as you can reverse them if necessary. The di-
rection of rotation is indicated by the symbols “=>”
and “<=”. Be sure to set the direction of servo rotation
BEFORE you adjust the remaining options!
CLEAR resets the direction of rotation to “=>”

In this menu you can adjust parameters which only
affect the servo connected to a particular receiver
output, namely the direction of servo rotation, neutral
point, servo travel and (if required) travel limit.
Basic procedure:
1. Hold the rotary control pressed in and select the
appropriate servo (1 to 12).
2. Turn the rotary control to select SEL , SYM or ASY
in the bottom line, prior to making the adjustments
required.
3. Press the rotary control: the corresponding input
fi eld is highlighted (dark background).
4. Set the appropriate value using the rotary control.
5. Finally press the rotary control again to end the in-
put process.
Important:
The numbers in the servo designations refer to the
receiver output socket to which a particular servo is
connected. These numbers do not necessarily coinci-
de with the numbering of the transmitter control func-
tion inputs; indeed any agreement would be pure-
ly accidental. The sophisticated programs of the
mx
-
24s mean that the numbers are unlikely to be the
same in any case. For example, changing the stick
mode does not affect the numbering (i. e. receiver so-
cket sequence) of the servos.
As a basic rule, always start with the servo setting in
the left-hand column!
