OUTPUT CH (channel selection)
If applicable, select the line "OUTPUT CH" with the
selection keys. Touch the
SET key of the right touch
pad. The value fi eld is shown highlighted. Now set
the desired channel (e.g. 01) with the selection keys
on the right touch pad. The following parameters
are always based on the channel set here.
Reverse (servo reversal)
Set the rotational direction of the servo connected to
the selected servo channel: ON / OFF
CENTER (servo center)
The active value fi eld (inverse video) in the "CENTER"
line shows the current impulse time in μs for the
control channel selected in the "OUTPUT CH" line.
The displayed value depends on the current position
of the control infl uencing this control channel and, if
applicable, the position of its trimming.
A channel impulse time of 1500 μs corresponds to the
standard center position and thus the conventional
servo center.
In order to change this value, select the "CENTER"
line then touch the
SET key. Now move the
respective transmitter control, joystick and/or trim
wheel to the desired position and store the current
control's position with another tap on the
SET key.
This position is saved as the new neutral position.
TRIM (trim position)
In the "TRIM" line" you can carry out the fi ne
adjustment of the neutral position of a servo
connected to the control channel selected in the
"OUTPUT CH" line using the selection keys of the
right touch pad in 1 μs increments. The value in the
"CENTER" line can be adjusted by the TRIM value
set here in a range of ± 120 μs.
Factory setting: 0 μs.
LIMIT–/+ (side dependent travel limit -/+)
This option is provided for the adjustment of a side-
dependent limit (limiting) of the servo travel (rudder
throw) of the servo connected to the control channel
selected in the "OUTPUT CH" line.
The settings for both directions are separate but both
are in a range of 30 … 150 %.
Factory setting: 150 % each.
PERIOD (cycle time)
In this line you determine the time interval of the
individual channel impulse. This setting is adopted for
all control channels.
With the use of only digital servos, a cycle time of
10 ms can be set..
In mixed operation or with use of only analog servos,
20 ms should absolutely be set, because the latter
can otherwise be "over-strained" and react with
"shaking" or "quivering" as a result.

The description of this menus necessitates a few
words of warning in advance:
"Do nothing" is the absolute worst thing to be done in
this regard. "HOLD" is prescribed in the base setup
model of the HoTT receiver.
In the event of a failure, in the best case scenario the
model fl ies straight ahead for an indefi nite amount of
time and then hopefully "lands" somewhere without
causing signifi cant damage! However, if something
like this happens in the wrong place at the wrong
time, the model may become uncontrollable and
"tear" across the fl ight fi eld completely out of control,
putting the pilot and spectators at risk.
Therefore, it would obviously be benefi cial to program
the the function "Motor off" at the very least, in order
to prevent such risks. If necessary, seek the advice of
an experienced pilot in order to fi ne a "logical" setting
for your model.
And then another brief notice regarding the three
possible versions of the
mc-20 HoTT transmitter for
the setting of Fail Safe:
The easiest, and recommended, way to fail-safe
settings is the use of the »Fail Safe« menu, which
can be reached from the multifunction menu, see
page 208.
Similarly, in order to achieve the same result
somewhat more laboriously, the "FAIL SAFE ALL"
option described on the following pages is also
available.
