and you gain experience, you might feel the need to try
out different control systems and other refi nements, and
to cater for these requirements you may fi nd that the text
deviates from the obvious order of options, or that one
or other of the options is mentioned more than once.
On the other hand, it may certainly occur that not every
step described in these instructions is relevant to a
particular model, just as some users might miss the
description of a particular step which is relevant to his
model only …
At this point, just before you start programming the
model data, it is worthwhile thinking carefully about a
sensible layout of the transmitter controls.
If the model in question is one with the emphasis on
“power” – whether the power of an electric motor or
internal combustion engine (glow motor) – you will
probably encounter few problems in this matter, because
the two stick units are primarily employed to control the
four basic functions “power control (= throttle)”, “rudder”,
“elevator” and “aileron”. Nevertheless, you still have to
call up the ...

i. e. throttle minimum forward (“Idle front”) or back (“Idle
rear”), because the program’s default setting is “no” (no
motor) when you fi rst set up a model memory.
The basic difference between “no” or “no/inv” and
“throttle min. front / rear” is the effect of the Ch 1 trim.
The trim is effective over the full stick travel if “no (/ inv)”
is entered, but it only affects the idle range if you enter
“throttle min. front or rear”. However, it also affects the
“direction of effect” of the Ch 1 stick, i. e. if you switch
from “front” to “rear” or vice versa, you do not also have
to reverse the direction of the throttle (or brake) servo.
For safety reasons you will also see a warning message
if you switch the transmitter on with the throttle stick
positioned too far towards “full-throttle” – but only if you
have already set “throttle min. front or rear”:

Your choice of “no” (no motor) or “throttle min. front or
rear” also affects the range of mixers available in the
»
wing mixer « menu. The mixers “Brake

N.N.*” are
only present if you choose “no” (no motor) or “no/inv”,
otherwise they are suppressed.
In addition to these basic matters you will certainly need
to consider carefully how best to control any “auxiliary
functions” present on your model.
In contrast, if your model is a glider or electric glider the
whole situation may be rather different. The immediate
question is: what is the best way of operating the motor
and braking system? Now, some solutions have proved
to be practical, and others less so.
For example, it is not a good idea to be forced to let
go of one of the primary sticks in order to extend the
airbrakes or deploy the crow braking system when your
glider is on the landing approach. It surely makes more
sense to set up switchable functions for the Ch 1 stick
(see example 4 on page 102), or to assign the braking
system to the throttle stick, and shift the motor control to
a slider – or even a switch. With this type of model the
electric motor is often little more than a “self-launching
system”, and is used either to drag the model into the
sky at full power, or to pull it from one area of lift to the
next at, say half-power, and for such models a throttle
switch is usually quite adequate. If the switch is posi-
tioned where you can easily reach it, then you can turn
the motor on and off without having to let go of the sticks
– even on the landing approach.
Incidentally, similar thinking can be applied to fl ap
control systems, regardless of whether they are “just”
the ailerons, or full-span (combination) control surfaces
which are raised and lowered in parallel.
Once you are satisfi ed that all these preparations have
been completed successfully, programming can com-
mence.
