User manual

Now move the corresponding control, control stick and/
or trim lever into the desired position, and save the
current control position by touching the SET button.
This position is saved as the new neutral position.
The displayed new value depends on the current
position of the control influencing this control channel,
and if applicable the position of the trim when you
touched to the SET button.
TRIM (trim position)
In the "TRIM" line, you can sensitively adjust the neutral
position in 1-µs increments of a servo connected to
the control channel selected in the line "OUTPUT CH".
Activate the value field by touching the SET button
at the bottom right of the display with a finger or the
provided stylus. The TRIM parameter is displayed in red.
The TRIM value set here can be adjusted ±120 µs in the
"CENTER" line with the INC or DEC buttons.
Factory setting: 0 µs.
LIMIT–/+ (side-dependent limit -/+)
This option is for adjusting a side-dependent limit of the
servo travel (rudder deflection) of the servo connected
to the receiver output selected in the "OUTPUT CH" line.
An adjustment within 30 … 150% is performed sepa-
rately for both directions.
Factory setting: 150%.
PERIOD (cycle time)
In this line, specify the periods for the individual channel
pulses. This setting is transferred for all control channels.
When using digital servos, you can set a cycle time of
10 ms.
If your system includes some or uses exclusively
analogue servos, always select 20 ms since the
analogue servos may be overloaded and respond by
"jittering" or "growling".
Touch the SET button at the bottom right of the display
with a finger or the provided stylus to switch to the
"FAIL SAFE ALL" line and activate the value field. "NO"
is displayed in red:. Set the parameter with the INC -
or DEC button to "SAVE".

As mentioned on page 114, the 9 control functions of
the 9-channel mz-18 HoTT transmitter, or the 12 control
channels of the 12-channel mz-24 HoTT transmitter,
can be distributed as desire within a receiver, or to
several receivers, or several receiver inputs can be as-
signed the same control function. This can for example
be done to control each aileron with two servos instead
of just one, or to control a large rudder with coupled
servos instead of a single servo.

Before describing this menu, a few precautionary words:
Doing nothing is the worst thing you can do
here. "HOLD" is the default in the base menu
of the HoTT receiver.
If a malfunction occurs, in a best-case scenario the
flying model will fly straight for a certain amount of time
and then land somewhere without causing too much
damage. If this happens at the wrong time and place,
the airplane may become uncontrollable and buzz the
flight field and endanger pilots and spectators.
It is therefore recommendable to at least program
"motor off" to prevent such risks. If necessary, consult a
competent pilot to find a recommendable setting for your
model.
An additional recommendation regarding the fail safe
setting for the three possible versions of the mz-18
HoTT and mz-24 HoTT transmitters:
The easiest and most recommendable way to make fail
safe settings is to use the "Fail Safe" submenu that can
be reached from the base menu and is described on
page 84.
Furthermore, although a bit more involved, the "FAIL
SAFE ALL" option described on the next two pages also
works.
Beyond this is the relatively complex method of
individual adjustments within the "RX FAIL SAFE" menu
of the "Telemetry" menu using the options "MODE",
"F.S.Pos." and "DELAY". The description of these
versions starts with the "MODE" option below.
