NER / teacher" as soon as a switch is assigned.
The model to be controlled by the pupil must be pro-
grammed completely in a model memory of the mx-
16 HoTT Teacher transmitter, i. e. with all its functions
including trims and any mixer functions. The HoTT re-
ceiver in the model must also be "bound" to the Teacher
transmitter, since it is this transmitter which actually
controls the model in Pupil mode - even in Trainer mode
operations.
The mx-16 HoTT Teacher transmitter MUST ALWAYS
BE SWITCHED ON FIRST. ONLY THEN MAY THE
CONNECTING LEAD BE PLUGGED INTO IT. If you
neglect this, the RF module will not be activated.
The mx-16 HoTT Teacher transmitter can be linked to
any suitable Pupil transmitter - even those operating on
the "classic" 35 / 40 MHz band.
However, if the connection at the pupil end is NOT
made using a two-pole DSC socket, but instead - for
example - using a three-pin Trainer socket from the
Graupner range, the basic requirement for a correct
connection with a Pupil transmitter is that PPM (18
or 24) modulation must ALWAYS be set on the Pupil
transmitter, regardless of the modulation used by
the Teacher transmitter.
Pupil transmitter settings
The model to be controlled by the pupil must be pro-
grammed completely in a model memory of the Teacher
transmitter, i. e. with all its functions including trims and
any mixer functions, and the HoTT receiver in the model
must be "bound" to the Teacher transmitter. In principle,
however, an mx-16 HoTT Pupil transmitter can also be
linked to a Teacher transmitter operating on the "classic"
35 / 40 MHz band.
The Pupil transmitter can be virtually any transmitter
from the former and current Graupner range with at
least four control functions. More information on this is
available in the main FS catalogue, and on the Internet
under www.graupner.de.
Some transmitters will need to be retro-fitted with the
appropriate module in order to act as the Pupil transmit-
ter. This should be connected to the transmitter circuit
board as described in the installation instructions sup-
plied in the set.
Information on the Pupil module required can be found
in the main Graupner FS catalogue and on the Internet
at www.graupner.de.
The Pupil transmitter must be connected to the Teacher
transmitter using the appropriate lead - see next double
page.
The control functions of the Pupil transmitter MUST
act directly on the control channels, i. e. the receiver
outputs, without the intervention of any mixers.
If you are using an "mc" or "mx" series transmitter,
it is best to set up a free model memory in the Pupil
transmitter with the required model type ("Fixed-wing"
or "Helicopter"). Assign the model name "Pupil" to the
memory, and set up the stick mode (Mode 1 ... 4) and
"Throttle min. forward / back" to suit the pupil's prefer-
ence. All the other settings should be left at the appropri-
ate default values. If you select the "Helicopter" model
type, the throttle / collective pitch direction and idle trim
must also be set accordingly on the Pupil transmitter. All
other functions, including mixer and coupling functions,
are carried out by the Teacher transmitter, which trans-
mits them to the receiver in the model.
If you are using an mx-20 or mc-32
transmitter, it is also necessary to match the type of
modulation to the numbers of the control channels to
be transferred; this is carried out in the "DSC output"
line of the "Basic model settings" menu. For example,
"PPM10" modulation carries control channels 1 ... 5,
and its signal packet only contains control channels 1
... 5 - but not channel 6. If you also wish the pupil to be
able to use this channel, then you must select a type of
modulation which includes it!
If you are using a "D" or "FM" type transmitter, you
should check the servo directions and stick mode, and
alter them by re-connecting the appropriate leads if re-
quired. All mixers should be switched off or set to "zero".
When assigning the control functions the usual conven-
tions should be observed:
Channel Function
1 Throttle / Collective pitch
2 Aileron / Roll
3 Elevator / Pitch-axis
4 Rudder / Tail rotor
If you wish to transfer other control functions to the
Pupil transmitter, in addition to the functions of the two
dual-axis sticks (1 ... 4), then you will need to assign
additional transmitter controls in the Pupil transmitter's
"Transmitter control settings" menu to those inputs
which correspond to transmitter control numbers 5 ... 8,
as released in the Teacher transmitter's "Trainer" menu.
Important:
• If you forget to assign a transmitter control, then
the servo or servos concerned will remain in the
centre position when control is transferred to the
HoTT Pupil
Pupil transmitter.
