The settings in the menus Calibrate and Assign-
ment are model-specific, i.e. they only apply to the
current model.
The menu Monitor shows the information which is
passed on to the servos in graphic or numerical form.

Menu Calibrate

17.1.
In the Calibrate menu you can adjust the travels,
centre and (if required) intermediate points for all ser-
vos in such a way that they move evenly and run to
the end-points required for your model.
Servo list, fixed-wing model
When you open the menu Calibrate , the screen
shows a list of all the servos which can be used with
your transmitter type (7, 9 of 12 servos). You can also
use the 3-D digi-adjuster to select servos 7 to 12,
which are not immediately visible when you open the
Calibrate menu.
17.1.1.

Sub-menus for individual servos

Rotate the 3-D digi-adjuster to select the servo to be
calibrated, then press the 3-D digi-adjuster to open
the Calibration sub-menu.
The sub-menus show the settings for REV/TRM and the
two to five curve points P1 to P5 :
Example: Fixed-wing model
Aileron servo
All changes to the parameters REV/TRM and the servo
calibration points P1 ... P5 are immediately reflected
in the diagram, making it quick and easy to check the
overall settings.
Line 1 always shows the name of the servo. Above
the diagram you will see the channel number (receiver
output) for the selected servo.

Servo list, helicopter
Example: Helicopter
Rotor HEAD f/b servo
The numbers 1 ... 5 below the diagram (X-axis) cor-
respond to the servo calibration points P1 ... P5 .
Parameter REV/TRM :
The first parameter REV/TRM has two functions:
a. Servo reverse ( REV ) alters the direction of rotation
of the servo.
To reverse the servo simply select the parameter
value and press the REV/CLR button:
the curve is "reversed"
the prefix changes
(only if the value for á is not 0% ).
b. Servo trim ( TRM ) shifts all points on the servo curve
in parallel.
Servo trim is used in order to compensate for dis-
crepancies from the correct neutral point of any
one control surface. This may occur, for example,
if you are using servos which do not feature ade-
quate temperature compensation, and are there-
fore subject to fluctuating neutral points.
The set trim value acts as an offset on all calibration
points P1 to P5 , and produces a parallel shift of the
curve, although the shape of the curve remains
unchanged. The effect is the same as the standard
trim procedure.
!
Note:
Use TRM only for temporary corrections!
The servo trim TRM should only be used to correct
trim deviations which occur when you are operating
the model, and not when setting up a new model.
In the latter case it is always better to adjust the
mechanical servo linkage.
Parameter P1 ... P5 :
You can solve many problems by making adjustments
to the servo calibration points (Parameter P1 ... P5 ).
In detail these are:
Establishing the maximum working range of the servo:
The values (servo travels) set at this point are never
exceeded (Protection from mechanical servo stalling,
Limit).
Setting symmetrical control surface travels.
Matching the travels of multiple servos to each other:
This prevents individual servos placing other ser-
vos under stress when two (or more) servos are
connected to the same control surface.
Compensating for mechanical differences in the
control surface linkage:
For example, if the individual control surfaces of a
multi-flap wing do not move exactly synchronously,
you can correct this by adjusting the intermediate
points P2 and P4 .
Careful and accurate calibration is particularly impor-
tant with servos to which a mixer has been assigned.
!
Note:
First adjust the mechanical linkage as accurately
as possible, and only then fine-tune the system
using the Calibrate menu.
