You can simply install the servos in the position which produces the
most direct pushrod linkages, and later select the appropriate
direction of servo rotation.
Press the "S" or "H"
button to select the
desired channel; the
number flashes.
Turn the 3-D hotkey left to switch it to "reverse" (R),and turn it to
the right to reset it to "normal" rotation (N) again.An arrow above
or below the servo channel number clearly indicates the set direc-
tion of rotation.
7.5 Servo centre offset (STRM)
When installing servos in a model it is
always best to fit them in such a way
that the servo output arm is at neutral
when the transmitter trim is also at
centre.Sometimes this is just not pos-
sible,and sometimes servos of a diffe-
rent make may not centre properly,and this function can be used to
set the servos of all eight functions exactly to the correct neutral
position.
Move to the Setup menu, and select
the desired servo channel with the "S"
or "H" buttons.Turn the 3-D hotkey to
adjust the neutral position of the
selected servo.
The adjustment range is -125% to +125%.
Hold the 3-D hotkey pressed in for 1 second to revert to the default
value (0%).
The screen shots above show a few typical settings.
It is important that the deviation from centre
is not excessive, otherwise the servo travel
will be distinctly different for each side of
neutral.This function is not intended for cor-
recting deficiencies in a model’s control sur-
face linkages.
For special applications the centre setting
can be offset by as much as 125%, in which
case the servo covers its full arc of travel,but
only in one direction.
7.6 Servo travel adjustment (ATV)
This function provides the means to adjust
servo travel separately for each side of
centre.The range of adjustment is 0 to +/-
125% of the total servo travel, including
trim.
This is sometimes necessary where a mecha-
nical restriction, e.g.the control system lin-
kage,prevents the servo moving over its full
travel.The servo travel can then be reduced
to suit the installation.The function affects
the selected servo channel,and also reduces
all mixed functions involving that channel. Any change to the set-
ting also affects the trim travel proportionally,together with any
Dual Rate settings you have entered.
- At the top of the screen a small arrow under the row of numbers
indicates the selected channel.
- Move to the Setup menu and press the "S" or "H" button to
select the desired servo channel.
Any changes you make to the settings affect this servo channel
only.
In the example shown
here the system is set
up to change the servo
travel for the first chan-
nel (left aileron) of the model stored in memory number 10.The
arrow indicates the direction of travel which can currently be chan-
ged.You select the other side of centre by moving the associated
transmitter control.
In the case of the horizontal transmit-
ter controls the arrow indicates right
and left.With the vertical control func-
tions the arrow indicates up and
down. Press the "S" or "H" button to
select a different channel.
Rotate the 3-D hotkey to adjust the
travel as a percentage value from 0 to
125%,or from 0 to -125%.This process
must be carried out separately for
each side of centre for each function.
Holding the 3-D hotkey pressed in for
one second resets the value to the default setting (100%).
If you set a negative value (in this case
-20%) using the 3-D hotkey, the servo
runs in the same direction regardless
of the direction in which you move
the stick.This can be used to control
special working systems on certain
types of multi-function model.
7.7 Transmitter control travel (AFR)
Function for adjusting the travel of the transmitter control within
the range 0…100%,separately for each side of centre.
In contrast to servo travel reduction
(described above),this function also
affects any associated mixer func-
tions which you have activated.
A reduction in transmitter control
travel therefore affects the mixing
rate when two functions are mixed
onto one servo.
