Страница: 97 / 132

97 Programming example: fi xed-wing model
Note:
If your model is fi tted with only one camber-changing
fl ap servo, you should still select “… 2fl ”. Later, in the
»
wing mixer « menu (see page 72), you should select
the “ail
¼
fl aps” mixer and set it to 0%. You can still
exploit all the other mixers available at that point in the
usual way.
At this juncture – if not before – you should check that
the servos are connected to the receiver in the standard
GRAUPNER sequence:
Airbrakes or throttle / speed controller
or speed controller (electric)
Right flap servo
Flap servo or left flap servo
Rudder servo or V-tail
Aileron servo or left aileron servo
Elevator servo or V-tail
Right aileron servo
Auxiliary function
Receiver power supply
Notes:
If you set up a V-tail, but the “up / down” and / or “left •
/ right” functions work the wrong way round, please
refer to the table in the right-hand column on page
38 for the remedy. The same procedure can be used
if you set up fl aperons (superimposed ailerons and
fl aps), and they work the wrong way round.
The following settings apply to a model with a “nor-
•
mal” tail and no motor (“no”); if your model has a V-
tail, the settings can be adopted virtually unchanged.
However, if the model is a delta or fl ying wing, the sit-
uation is not quite so straightforward. A special pro-
gramming example covering this model type will be
found in the section starting on page 108.

In this menu you can set various parameters relating to
the servos, i. e. “
direction of rotation ”, “ neutral set-
ting ” and “ servo travel ”, to suit the requirements of the
model.
By “requirements” we mean adjustments to servo centre
and servo travel which are needed to compensate for
minor tolerances in servos and slight inaccuracies on
the model itself.
Note:
The facilities provided in this menu for setting asym-
metrical servo travels are NOT intended as a means of
setting up differential travel on ailerons and / or camber-
changing fl aps. There are more suitable options for this
in the form of specifi c functions in the »
wing mixer «
menu; see the fi rst two options in the picture on the right.
Once you have completed the settings described thus
far, a fi xed-wing or powered model aircraft (the latter
if you enter the idle direction of the throttle stick in the
“motor on C1” line of the »
base sett. « menu) will, in
principle, fl y.
However, there are no “refi nements” in this set-up, and
it is the refi nements which will give you more long-term
pleasure in your fl ying. Assuming that you are already
capable of controlling your model safely, it’s time to get
a taste of these extra facilities; to this end we now move
on to the ...

Note:
This menu will show a varying range of options depend-
ing on the information you have entered in the
»base
sett.« menu. In the illustration above, the full range is
shown, as generated by the entries “2ail 2fl ” in the “aile/
fl ap” line, and “no(/inv) in the “Motor in C1” line.
Of particular interest at the moment are “ diff aile. ”
(aileron differential) and the “ ail
¼
rudd ” (aileron
¼
rudder) mixer, in some cases the combi-switch (coupled
aileron and rudder) and perhaps the mixers “
brak
¼
aile ” and “ brak
¼
fl ap ”.
As already described in detail on page 73, the purpose
of “
diff aile. ” (aileron differential) is to eliminate adverse
yaw.
When a model aircraft turns, the down-going aileron
produces more drag than the up-going one if both move
through the same angle, and this causes the model to
yaw in the opposite direction to the turn. This can be
eliminated by setting differential servo travel. A value be-
