-16iFS as Pupil transmitter
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 iFS receiver of the model
must be “bound” to the
Teacher transmitter . In principle,
however, an
mx
-16iFS Pupil transmitter can also be
linked to a Teacher transmitter operating on the “classic”
35 / 40 MHz band, since the PPM signal required for this
is present at the DSC socket of the
mx
-16iFS.
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. To accomplish
this 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”, and set
up the stick mode (Mode 1 … 4) and “Idle / collective
pitch forward / back” to suit the pupil’s preference. All the
other settings should be left at the appropriate default
values. If you select the “Helicopter” model type, the idle
trim must also be set accordingly on the Pupil transmit-
ter. All other functions are carried out by the Teacher
transmitter.
Important:
ALWAYS leave the On / Off switch on the Pupil
transmitter at the “ OFF ” position, as this is the only
way to ensure that an RF signal is not radiated by
the transmitter module, even when the DSC lead is
plugged in. At the transmitter’s basic display the
message “DSC” will appear to the left of “iFS”.

The two transmitters should now be inter-connected
using the appropriate Trainer lead: see the picture on the

When assigning the control functions the usual conven-
tions should be observed:

mx
-16iFS as Teacher transmitter (total control
transfer)
The model to be controlled by the pupil MUST be
programmed COMPLETELY in a model memory of the
mx
-16iFS Teacher transmitter, i. e. with all its functions
including trims and any mixer functions, and the iFS
receiver must be “bound” to the Teacher transmitter.
The two transmitters should now be inter-connected
using the appropriate Trainer lead: see the diagram on
the right-hand page; note that the Teacher transmitter
MUST
always be switched on before the Trainer lead is
connected .
Total control transfer is the only option when using the
mx
-16iFS transmitter with a Pupil transmitter.
The
mx
-16iFS Teacher transmitter can also be linked to
any suitable Pupil transmitter, even those operating on
the “classic” 35 / 40 MHz band; see right-hand picture
on the next double page. For example, an
mx
-16iFS
Teacher transmitter can also be connected to an
mx
-
16s Pupil transmitter. In such cases the basic require-
ment for a correct link with a Pupil transmitter is
that PPM modulation is ALWAYS set on the Pupil
transmitter, regardless of the modulation used by
the Teacher transmitter.
If you are using a Trainer lead with the Order No. 3290.7
or 3290.8 , connect the plug marked “ M ” (“Master”) to the
socket on the Teacher transmitter, and the plug marked
“
S ” (“Student” or “Slave”) to the Pupil transmitter’s
socket. Both transmitters must be prepared as described
in the operating instructions supplied with them.
Select the “Trainer” line in the »
base sett. « menu, and
assign a Trainer change-over switch. Ideally this should
be the momentary button SW 4 / PB 8, assigned as
“push-button 8” (see page 33), so that the fl ight tutor can
instantly resume control from the Teacher transmitter at
any time.

As long as this button is held pressed in, the system is
in Pupil mode. As soon as the button is released, the
Teacher transmitter resumes full control.
The basic display of the
mx
-16iFS Teacher transmitter
does not change when Pupil mode is selected.
