Introduction
 mx-20 
 the newest generation of remote  control technology
HoTT (Hopping Telemetry Transmission) is a synthesis 
of know-how, engineering and testing done around the 
world by experienced model pilots. HoTT technology 
combines 2.4 GHz band transmission/reception with 
bi-directional communications via a "return channel" 
integrated into the receiver unit. 
Based on the Graupner/JR computerized remote 
control system 
mc-24 that was introduced in 1997, 
the 
mx-20 HoTT remote control system has been 
especially developed for experienced RC pilots All 
conventional model types can be readily operated 
with the 
mx-20 HoTT system, regardless of whether 
the model is a winged aircraft, helicopter, ship or land 
vehicle. 
Complex mixed-control functions of guiding surfaces are 
often necessary for winged aircraft (rudder, elevators) 
and helicopter models (swashplate). Thanks to this 
computer technology it is possible to activate these 
diverse functional requirements with a single "press 
of a button". Simply select the given model type from 
the 
mx-20 HoTT program and its software will 
automatically assemble signifi cant mixed-control and 
coupled functions. This eliminates the need for separate 
modules in the transmitter to implement complex 
coupled functions and also makes sophisticated 
mechanical mixer mechanisms in the model 
unnecessary. The 
mx-20 HoTT remote control system 
offers the highest level of safety and reliability. 
Its software is clearly structured. Functionally-related 
options are clearly arranged by content in a simple 
organization.
The 
mx-20 HoTT remote control system has 24 
model memory locations. Additional fl ight-phase-specifi c 
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 
fl ight maneuvers at the "press of a button". 
The large graphic display is well organized and simple 
to operate. The mixer's graphic representation is 
exceptionally helpful. 
Familiarization with the various functions in this remote 
control system is quick, even for a beginner, because 
of its clear, straightforward program structure. The user 
makes his settings with the four-way, touch sensitive 
buttons located to the left and right of the high-contrast 
display. Thus, with only little practice, the pilot learns to 
implement all of the remote controlled model options 
with which he/she has experience.
This Graupner HoTT technique theoretically allows over 
200 models to be operated simultaneously However, 
because of the interspersed radio-frequency utilization 
permitted by certifi cation for the 2.4 GHz ISM band, this 
number is signifi cantly 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 factor 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 coordinate transmitting frequencies with other pilots in 
the vicinity (which is sometimes quite diffi cult in broken 
landscapes, such as on  hillside slopes) represents an 
enormous boost for remote control operating security.
The integrated telemetry menu affords simple access 
to data and HoTT receiver programming. For example, 
this can be used to map receiver outputs, assign control 
functions to multiple servos, and to coordinate the 
magnitude and direction of multiple servo movements 
with one another. 
This handbook describes every menu in detail. There 
are tips, many notices and programming examples to 
supplement the descriptions and also explanations for 
model specifi c technical terms, like transducer, dual 
rate, butterfl y, etc.
An appendix is provided which contains additional 
information about the HoTT system. This manual is 
rounded out with the conformity declaration and the 
guarantee certifi cate for the transmitter.
 
Please observe the safety notices and technical notices. 
Read the instructions carefully then test all functions by 
simply attaching servos to the receiver included in the kit 
for order no. 33124. When doing this, please observe the 
corresponding notice provided on page 20. This will help 
you learn the essential operating steps and functions of 
the 
mx-20 HoTT in the least amount of time.
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 fun and success 
with your 
mx-20 HoTT remote control system of the 
newest generation
