Incorporating An Electric Drive - GRAUPNER HoTT MC-16 Series Programming Manual

Integration of an electric drive into the model programming
An electric drive can be controlled in different ways:
The simplest method to integrate one such drive into
the model programming is with the use of a throttle/
brake stick (C1). However, since this is already speci-
fied for the brake system in the course of the model
programming described above, either the switchable
solution described beginning on page 291 or even
the use of an alternative control is possible.
As a suitable alternative, one of the two 3-position
switches would be better than one of the proportio-
nals controls. However, either one of the two side
proportional rotary controls are also well suited to ac-
tivation of a motor without having to let go of the stick.
An alternative would also be one of the two-stage
switches. Basically, whatever switch is used should be
located where it is within convenient reach.
Before we turn to the individual examples, it is im-
portant must be noted that all inputs in the »Control
adjust« menu can be selectively programmed as
flight-phase specific ("PH" in the "type" column) or
model memory specific ("GL" in the "type" column)!
However, since the drive should usually be available
depending on the current flight phase, we recom-
mend leaving the standard default "GL" ("global") in
the "type" column which your are using.

A common option in the following examples 1 ... 5,
the automatic tracking of the elevator trimming in the
power flight, should also be mentioned at the begin-
ning of this section:
If it becomes apparent after the initial power flights
that the model must be continuously corrected with
the elevator while the motor is switched on, this situ-
ation can be corrected by setting a free mixer and
adjusting it accordingly. For this purpose, switch to the
menu ...
»Free mixers« (beginning on page 205)
... and program one of the linear mixers, M1 ... 8, or
even one of the curve mixers, C9 ... 12, from "chan-
nel controlling the motor" according to "EL", for exam-
ple:
M1 8 EL
M2 ?? ??
M3 ?? ??
M4 ?? ??
M5 ?? ??

Proportional control usage
If one of these controls is used, the connection is very
simple. Only the motor controller (speed control) has
to be connected to a free servo connection 5 ... 12
max. of the receiver.
Bear in mind that, depending on the model type and
number of aileron and flap servos, the output 2 + 5
and may be 6 + 7 are already linked.
Therefore connect your speed controller to the next
free input and assign the selected input – for example,
"In8" – to one of the transmitter's proportional controls,
for example the left-side proportional rotary control.
This is done in the menu ...
»Control adjust«
Select the desired line with the  selection keys of
the left or right four-way button. A tap on the center
SET key of the right four-way button will activate the
"Control assignment". Now move the selected propor-
tional control. After a short time, an entry, e. g. "Lv2",
will appear in the inverse video field:
In5
In6
In7
In8
However, since propulsion must usually be available,
independent of the current flight phase, leave the
default value "GL" in the "type" column – as already
mentioned earlier in this section.
