10 Introduction
mx-16 the latest generation of radio control technology
HoTT (Hopping Telemetry Transmission) is the synthe-
sis of expertise, engineering and world-wide testing by
professional pilots. The equipment operates on the 2.4
GHz band, and offers bi-directional communication be-
tween transmitter and receiver via a down-link channel
integrated into the receiver.
The
mx-16
HoTT RC system is based on the Graup-
ner/JR
mc-24
computer radio control system which
was introduced back in 1997. It has been developed
specifically for the beginner, but the
mx-16
HoTT is
still capable of controlling all current model types with-
out problem - whether fixed-wing model or helicopter,
model boat or car.
In the area of fixed-wing models and helicopters it is
often necessary to employ complex mixer functions
for the control surfaces or the swashplate actuation
system. Computer technology enables you to activate
a vast range of functions to cope with special model
requirements – just by pressing a button. With the
mx-
16 HoTT all you do is select the appropriate model
type, and the software then presents you automatically
with the appropriate mixer and coupling functions. This
means that the transmitter requires no additional mod-
ules in order to implement complex coupled functions,
and you can forget all about old-fashioned mechanical
mixers in the model. The
mx-16 HoTT provides an
extremely high level of safety and reliability in use.
The
mx-16 HoTT offers twenty model memories, each
of which can store model settings for different flight
phases. Individual phases can be called up in flight
simply by operating a switch, so that you can try out
various settings quickly and without risk. This can be
for test purposes or for varying parameters for different
phases of flight.
The large graphic screen makes operating the trans-
mitter a simple, intuitive process. Mixers and other
functions can be displayed in graphic form, and this is
extraordinarily helpful.
The beginner quickly becomes familiar with the different
functions thanks to the clear, logically arranged pro-
gram structure. Four-way touch-sensitive buttons to left
and right of the high-contrast screen are used to enter
settings, allowing the user to exploit all the options he
needs, in accordance with his experience in handling
radio-controlled models.
In theory the
Graupner|SJ HoTT process allows more
than 200 models to be operated simultaneously. Al-
though in practice the mixed operation of different tech-
nical systems in the 2.4 GHz ISM band – as required
by the approval regulations – reduces this number
considerably. Generally, however, it will always be pos-
sible to operate even more models simultaneously on
the 2.4 GHz band than on the 35 / 40 MHz frequency
bands which we have used to date. However, the actual
limiting factor – as it has always been – is likely to
remain the size of the (air-) space available. The simple
fact that no frequency control procedure is necessary
equates to an enormous gain in safety, especially at
flying sites such as gliding slopes where groups of pilots
may be distributed over a large area, with nobody in
overall control.
The integral Telemetry menu provides a simple means
of accessing data and programming HoTT receivers.
For example, this method can be used to map receiver
outputs, distribute control functions to multiple servos,
and match servo travels and directions to each other.
This manual describes each menu in detail, and also
provides dozens of useful tips, notes and programming
examples to complement the basic information. More
general modelling terms, such as Transmitter controls,
Dual-Rates, Butterfly (Crow) and many others, are all
explained in the manual.
Please refer to the Appendix for additional information
on the HoTT system. This manual concludes with the
transmitter’s conformity declaration and guarantee
certificate.
Please read the safety notes and the technical informa-
tion. We recommend that you read right through the
instructions with great care, and check all the functions
as described in the text. This can be carried out simply
by connecting servos to the supplied receiver, and
watching their response as you program the transmit-
ter. However, please read the notes on page 20 in this
regard. This is the quickest method of becoming familiar
with the essential procedures and functions of the
mx-
16 HoTT.
Always handle your radio-controlled model with a
responsible attitude to avoid endangering yourself and
others.
The
Graupner team wishes you great pleasure and suc-
cess with your
mx-16
HoTT - a radio control system of
the latest generation.
