Column 3 “centre”
The facility to offset the servo travel centre is intended
for adjusting servos whose centre setting is not standard
(servo centre point at 1.5 ms), and also for
minor adjus-
tments, e.g. when fi ne-tuning the neutral position of the
model’s control surfaces.
The neutral position can be shifted within the range
-125% to +125% of normal servo travel, regardless of
the trim lever position and any mixers you have set up.
The centre setting affects the associated servo directly,
independently of all other trim and mixer settings. Howe-
ver, please note that an extreme shift of the servo’s neu-
tral point may result in servo travel to one side of neutral
only, as total servo travel is limited to +/-150% for both
electronic and mechanical reasons.
Pressing
CLEAR resets the value to “0%”.
In this menu you can adjust parameters which only af-
fect the servo connected to a particular receiver output,
namely the direction of servo rotation, neutral point and
servo travel. Always start with the servo setting in the
left-hand column.
Basic procedure:
1. Hold the SELECT button pressed in and select the
relevant servo (1 to 8) using the right-hand rocker
button.
2. Use the right-hand rocker button to select SEL , SYM
or ASY in the bottom line, prior to making the adjust-
ments required.
3. Press the SELECT button: the corresponding input
fi eld is highlighted (inverse video).
4. Set the appropriate value using the right-hand rocker
button.
5. Finally press the SELECT button again to conclude
the input process.
Important:
The numbers in the servo designations refer to the re-
ceiver output socket to which a particular servo(s) is
connected. These numbers do not necessarily coincide
with the numbering of the transmitter control function in-
puts, and indeed any coincidence would be purely acci-
dental. The sophisticated programs of the mx-16s 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 socket sequence) of
the servos. The same applies to any changes you make

(see pages 41 and 46).
Column 2 “reverse”
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 directions
when installing the mechanical linkages in the model, as
you can reverse them as and when necessary. The di-
rection of rotation is indicated by the symbols “=>” and
“<=”. Be sure to set the direction of servo rotation before
you make adjustments to the remaining options!
Pressing
CLEAR resets the direction of rotation to “=>”.
