Control E-motor and crow alternatingly with C1 joystick
Example 4
Before we discuss the programming of this fourth
example or turn the to the expansion of the previously
described basic programming, a few words should be
said about the position of the throttle/brake joystick
with "Motor OFF" or "Brake OFF". Normally the C1
control joystick is moved forward for the throttle control
and backward for the extension of the brake. If, in this
"classic" assignment, you switch to the brake system
with Motor "OFF" (= joystick "back"), for example,
"full brake" would be applied after the switch time you
specifi ed in the "Phase setting" menu, or vice versa,
if you switch to drive with the "brake retracted" the
motor would be switched to "full power" within this time
range...
A "glider pilot" can make the best of this
"Emergency" – normally with "brake retracted = front" –
by switching to motor "ON" only if necessary and then
the power decreases, if applicable (and hopefully you
will not forget to push the C1 joystick "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".
Whatever the case may be, the mc-32 HoTT
transmitter enables both variants. In the following text,
however, the combination of the two "OFF" positions
to "front" is assumed. 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"
(beginning on page 82)
Here you fi rst 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":

Notice:
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 joystick. Since the C1 trimming is not normally
used with electric drives, however, this has no further
relevance.
You adjust the "according to your model, in this case
"normal".
In the "Aileron/fl aps" line you enter the correct number
of aileron and fl ap servos – in this example "2 AIL".
In the last line you leave the standard entries for the
selection of "Brake retracted = rear". On the other hand,
if you prefer "Brake retracted = front", select the "Brake
offset" line and defi ne the offset point – as described on
page 83 – as "front":
M O D E L
Motor at C1
Tail type
Aile/flaps
Brake Off
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
front
ensures that all brake settings remain at "neutral", even
with minor deviations from the limit of the brake fl ap
2AIL
control. At the same time, the effective control path is

automatically spread to 100 %.

For this reason, in the next step it must be ensured that
the infl uence of the C1 joystick on the motor can be
infl uenced. For this purpose, switch to the menu ...
"Phase setting"
... and assign a meaningful name, such as "normal",
from the list for "Phase 1" after activation of the selection
fi eld in the "Name" column. The asterisk in the second
column indicates which phase is currently active.
As long as no phase switches are assigned, this is
always Phase 1. Give "Phase 2" the name "Landing" in
accordance with the example.
In the "Ph.Tim" column you can assign a so-called fl ight
phase timer for the measurement of the motor running
time and/or the gliding times as necessary for each
phase. You could, for example, assign one of the "Timers
1 ... 3" to the "Normal" fl ight phase in order to measure
the total motor run time through the C1 joystick:
