11.5.2. What do the model templates contain?
a. Basic mixer settings
The main input is set to full servo travel; all other
inputs to OFF.
b. Basic transmitter control settings
Travel and Dual-Rate to 100%
Expo to 0%
Trim increment to 1.5%.
c. Basic servo settings
Servo travels 100%
Centre to 0%.
d. Basic flight phase settings
All four possible flight phases are assigned names.
However, only the following are unlocked by default:
- for fixed-wing models: NORMAL
- for helicopters: HOVER and AUTOROT (Autorotation).
11.5.3. Which model templates are available?
1. BASIC 7. HELImech
2. ACRO 8. HELIccpm
3. HOTLINER
4. DELTA
5. GLIDER
6. 4 FLAPS
Amongst these eight model templates you are bound
to find one which is so close to your model that only
minor corrections are necessary to produce a perfect
match.
For a detailed description of the model templates
please refer to section (Î 21.1.) “Fixed-wing models”
and (Î 21.2.) “Helicopters”.
11.6. Servo configuration
The term servo configuration refers to the order in
which the servos are connected to the receiver output
sockets. There are four possible choices:
a. M-PCM
for use with the new sequence optimised for the
new M-PCM transmission mode
b. MPX-UNI
the standard sequence used for many years by
MULTIPLEX and many other makes of transmitter
c. FUTABA
d. JR.
If you have already flown the model with a FUTABA or
JR transmitter, we recommend that you select the cor-
responding configuration.
Note: the receiver output assignment for the four pos-
sible configurations can be found in the Overview
(Î 21.3.) “Servo configuration”.
11.7. Servo calibration
The advantage of our idea of “global mixers” (Î 11.4.) is
that any change which affects multiple servos sharing
the same function only has to be changed as a single
numerical value if you wish to alter a control surface
travel.
To ensure that this procedure works properly, the con-
trol surface travels for servos with the same function
must be set to the same values. Any mechanical dis-
crepancies are corrected in this way.
Example: when a 100% aileron signal is present, the
left aileron deflects by 13.5 mm, the right only 12 mm.
The manufacturer of the model recommends a travel
of 11 mm. You can now calculate the required servo
travel as a percentage value, and set up the model in
the menu ¤Servo.Calibrate.
Typical calculation, for left aileron:
Nominal deflection: 11.0 mm
Actual deflection: 13.5 mm
Formula: (Nom. / Act.) * 100% = (11 / 13.5) * 100%
= 81.48%
You should therefore set: 81%
For the right aileron the setting is as follows:
(11 / 12) * 100% = 91.67% = 92%
Advantage: when the calibration process is complete,
a value of 100% relating to transmitter controls and
mixers means that both ailerons deflect by 11 mm.
The following is also true: 1 mm travel equals a value
of 9%. If, for example, you now wish to raise the ailer-
ons by 2 mm for a particular task, then a mixer input
(Flap control) of 18% is necessary.
11.7.1. What can be calibrated?
Two, three or five points on the servo curve can be
accessed for the calibration process. The number of
points is determined when a new model is set up, but
for each servo this can also be changed subsequently
to any other value in the menu ¤Servo.Assign.
a. 2P (2-point curve)
Only the servo end-points (Points P1 and P5) are
changed. Between these two points the servo
travel is linear.
Application: retracts, tow release, throttle, ...
b. 3P (3-point curve)
In this case the servo centre (Point P3) can be ad-
justed in addition to the two end-points. If you off-
set the centre, the two travels between centre and
end-point remain linear, i.e. the servo curve is now
“bent”.
Application: this equates to the standard form of
servo travel adjustment.
c. 5P (5-point curve)
Adding the two intermediate curve points (Points
P2 and P4) produces a deliberately ”distorted”
servo curve.
Application: this option can be used to generate
non-linear servo travel even for control functions
for which Expo or a curve are not available.
