The Newest Generation of Remote Control Technology

The technical advances across the entire spectrum of

model building is an ever-present challenge to design

engineers. This is why the introduction of new trans-

mission technology in the 2.4 GHz band represents a

new milestone.

The HoTT-System (Hopping Telemetry Transmission)

developed by Graupner is a synthesis of know-how,

engineering and testing done around the world by

professional pilots.

Established Graupner HoTT techniques theoretically

permit over 200 models to be operated at the same

time. However, because of the interspersed radio-

frequency utilization permitted by certiﬁcation for the

2.4 GHz ISM band, this number is signiﬁcantly lower

in practical application. Nevertheless, in general

more models can be operated simultaneously in the

2.4 GHz band than would be the case in conventional

35 or 40 MHz frequency bands. The real limiting fac-

tor is – as often before – is still likely to be the size of

available operating space (i. e. airspace for aircraft).

Alone the fact that it is no longer necessary to coor-

dinate transmitting frequencies with other pilots in the

vicinity (which is sometimes quite difﬁcult in broken

landscapes, such as on hillside slopes) represents an

enormous boost for remote control operating security.

Bidirectional communication between transmitter

and receiver, by way of a return channel built into

the receiver, permits convenient access to data and

programming in the HoTT receiver. For example, this

makes it possible to swap receiver outputs or to divide

up control functions among multiple servos (channel

mapping). Servo travel and servo rotation directions

in the receiver can also be matched to one another

with these facilities. Telemetry data, like VARIO and

GPS data, can be called up from optionally available

modules.

The

mc-16 HoTT and mc-20 HoTT radio control

sets are based on the Graupner/JR mc-24 computer

radio control system, which was introduced back in

1997. The new equipment has been specially devel-

oped for the advanced RC pilot. The transmitters of

this series offer an unprecedented level of security

and reliability combined with outstanding operating

convenience and ease of use.

Both these HoTT systems can easily be used to oper-

ate all current model types, whether your preference

is for ﬁxed-wing model aircraft or helicopters, model

cars or boats.

For example, every

mc-16 HoTT and mc-20

HoTT transmitter is fully equipped in terms of soft-

ware and hardware to allow the use of the renowned

NAUTIC modules. A further innovation is the “channel

sequencer” – available as standard only on the mc-

20 HoTT – which provides a means of automating

servo sequences involving up to three servos.

However, it is ﬁxed-wing model aircraft and helicop-

ters in particular which call for complex mixed func-

tions involving the control surfaces or swashplate

control system. In this respect the latest computer

technology makes it extremely simple to program the

system to cope with a vast range of model require-

ments: simply select the appropriate model type in

the program of your HoTT transmitter, and the soft-

ware automatically sets up all the relevant mixing

and coupling functions. Separate modules for imple-

menting complex coupling functions are no longer

required, and complicated mechanical mixers in the

model are completely superﬂuous.

Additional ﬂight-phase-speciﬁc settings can be stored

in every model memory location. For example, such

settings can be made for various parameters that can

be called up to implement particular ﬂight maneuvers

at the “press of a button”. Additional model memo-

ries can be stored on the SD card, which is included

standard with the set. Even telemetry data can be

recorded for subsequent evaluation on a PC.

Since the

mc-20 HoTT is equipped with two dis-

plays, the lower display has been optimized for com-

prehensible, simple operation of the software. The

graphic representation of mixer functions is particu-

larly helpful. The upper display allows telemetry data

to be called up from the receiver.

Functionally-related options are clearly arranged by

content in a simple organization. The clear, compre-

hensible program structure permits a beginner to

quickly become familiar with the various functions and

able to use all options pertinent to his level of exper-

tise with remote control models.

This handbook describes every menu in detail. There

are tips, many notices and programming examples to

supplement the descriptions and also explanations for

model speciﬁc technical terms, like transmitter con-

trol, dual rate, butterﬂy, and so on.

Please observe the safety notices and technical

notices. Read through the instructions attentively.

Before usage, test all functions by simply attaching

servos to the receiver included in the set. While doing

this, observe respective notes on page 77. This will

help you learn the essential operating techniques and

functions of your HoTT transmitter.

Always handle your remote controlled model with a

sense of responsibility so that you do not endanger

yourself or others.

The Graupner team wishes you much pleasure and

success with your HoTT transmitter system, the new-

est generation of remote control systems.
