Wireless Hott System - GRAUPNER mx-16 HOTT Programming Manual

Wireless HoTT system

The mx-16 HoTT Trainer system can also be operated
by wireless means. In this case the Teacher transmitter
is "connected" to a Pupil transmitter as described in the
following section. However, the trainer model must first
be bound to the PUPIL transmitter. This configuration is
possible between transmitters which feature the "BIND:"
option in the "Trainer" menu.
Preparations for Trainer mode operations
Teacher transmitter
The trainer model must be programmed completely,
i. e. with all its functions including trims and any mixer
functions, in a model memory of the HoTT Teacher
transmitter. This means that it must be possible to
control the trainer model fully, without restriction, by
the Teacher transmitter. However, the preparations
are concluded by binding the training model to the
Pupil transmitter; you will find a detailed description
of the binding procedure on pages 80 and 88.
Pupil transmitter
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.
When assigning the control functions the usual conven-
158 Program description: Trainer system
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 further control functions to the
Pupil transmitter, i.e. in addition to the functions of the
two dual-axis stick units (1 ... 4), then you will need to
assign transmitter controls to those inputs which cor-
respond to the function or transmitter control inputs 5
... 8, as selected in the Teacher transmitter's "Trainer"
menu; this has to be carried out in the Pupil transmitter's
"Transmitter control settings" menu.
Important:
If you should forget to assign a transmitter control
at the Pupil end, the servo or servos concerned
will remain at their centre position when control is
transferred to the Pupil transmitter.
Preparing the Teacher and Pupil transmitters
Once you have bound the trainer model to the Pupil
transmitter, the Teacher transmitter should also be
switched on. Now use the arrow buttons or the left or
right-hand touch-key to leaf through on both transmitters
to the "Trainer" menu point in the multi-function menu:
