In the last line you leave the standard entries for the
selection of "Brake retracted = front". On the other
hand, if the preference is for "Brake retracted = rear",
select the "Brake offset" line and define the offset
point – as described on page 105 – as "rear". In the
process, if the offset point is not placed completely
at the end of the control travel, the remainder of the
travel is "idle" up to this limit.

This idle path ensures that all brake settings remain
at "neutral", even with minor deviations from the limit
of the brake flap control. At the same time, the effec-
tive control path is automatically spread to 100 %.
For this reason, in the next step it must be ensured
that the influence of the C1 stick on the motor can be
influenced. For this purpose, switch to the menu …
»Phase settings« (page 154)
… and assign a meaningful name, such as "Normal",
from the list for "Phase 1" after activation of the selec-
tion field in the "Name" column. The asterisk in the
second column indicates which phase is currently ac-
tive. As long as no phase switch has been assigned,
this is always Phase 1. "Phase 2" can be given, ap-
propriate to the example, the name «Landing».
However, if you have a different preference, it is not
a problem: The only difference from the described
version lies in the logical selection of "Throttle min
rear/front" and, if applicable, of a corresponding brake
offset in the menu …
»Model type« (page 104)
Here you first specify in the "motor" line whether the
throttle minimum position (= Motor "OFF" position)
should be at the "front" or "rear" – as already discussed:
In the following programming example, "Motor OFF"
and "Brake OFF" are combined at "front":
Tail type
Motor on C1
Normal
Aileron/camber flaps
1 AIL
M O D E L T Y P E
Brake Offset Input 1+100%
SEL
Thr. min front
Note:
With the selection of "Throttle min front/rear"
the trimming will then only have an effect in
the "idle" direction of the motor and is not the
same as with the "none" entry, having the same effect
at every position of the C1 stick. Since the C1
trimming is not normally used with electric drives,
however, this has no further relevance.
You adjust the “Tail type” according to your model, in
this case "normal".
In the “Aileron/flaps” line you enter the correct number
of aileron and flap servos – in this example “2 AIL”.

Example 4
Before we discuss the programming of this fourth
example or turn to the expansion of the previously
described basic programming, a few words should be
said about the position of the throttle/brake stick with
"Motor OFF" or "Brake OFF". Normally the C1 con-
trol stick is moved forward for the throttle control and
backward for the extension of the brake. However, if
for this type of "traditional" assignment, for example, a
switchover of the brake system is to take place for the
"Motor OFF" condition (stick "back") then a switchover
to "full brake" would take place immediately after the
pre-set switchover time specified in the »Phase set-
tings« menu, and the opposite will take place when
"brakes retracted" is switched over to propulsion
causing the motor to switch over to "full power" within
this time range …
A "glider pilot" can make the best of this "Emer-
gency" – normally with "brake retracted = front" – by
switching to motor "ON" only if necessary so that
power decreases, if applicable (and hopefully not
forgetting to push the C1 stick "forward" again when
switching back). A typical "motor pilot", on the other
hand, operates in the opposite manner, only switching
to the brake if necessary, etc... You can also combine
the "Zero point" of both systems to avoid confusion,
whereby a "glider pilot" would tend prefer the "front"
and a "motor pilot", on the other hand", would likely
prefer the "rear".
Whichever the case may be, the
mc-32 HoTT
transmitter permits both variants. In the following text,
however, the combination of the two "OFF" positions
to "front" is assumed.
