4. Servo Match Function
The Servo-Match function provides the facility for adjusting the centre
position and end-points of the servos connected to the backer. If you
have a model aircraft with more than one servo per control surface, this
makes it possible to set up multiple servos to move to identical positions
at identical times. Since this ensures that the servos do not work against
each other, their effective life is increased, and more power is available
to move the control surfaces; matched servos also draw lower current.
It is also possible to reverse the direction of rotation of individual servos.
This function is useful if you wish to employ fewer channels at the
transmitter. For example, the right and left elevators, or the right and left
landing flaps, can be controlled using only one radio channel. In models
such as jets and warbirds, which by their nature have a large number of
working systems, this feature can be very important, but it can also
make transmitter programming much easier with other types of model.
Select
SERVO-MATCHING
in the Main menu, and the following screen
display appears:
To ensure accurate servo matching, the output to be adjusted must first
be initialised. Leave the associated transmitter stick at centre. Move the
cursor to
INIT OUTPUT
and press the SET button. Now move the
transmitter stick to both end-points.
The graphic display shows the movement of the upper arrow, which
indicates the input signal. The bar inside the box shows the movement
of the output. The three lower arrows indicate the centre and end-point
positions which are ‘learned’ in this process.
Note:
if the channel has not yet been initialised, it is not possible to
select the
START SERVOMATCHING
and
REVERSE SERVO
points.
