11Remote control set description
mc-16 and mc-20 series computer systems
two remote control sets with 2,4-GHz-Graupner|SJ-HoTT technology
(Hopping Telemetry Transmission)
Technology that enthralls.
The superior functional security of Graupner/SJ
HoTT technology accomplished with bidirectional
communications between transmitter and receiv-
er with integrated telemetry, freely programmable
voice output via headset connector, and ultra-fast
response times.
Simplified programming using capacitive touch-
buttons on the
mc-20 HoTT and four-way push-
buttons on the mc-16 HoTT.
High-contrast eight-line graphic screen provides
a clear display of all set-up parameters. Switcha-
ble blue backlighting. The
mc-20 HoTT features
an independent second screen for displaying te-
lemetry data. Storage of telemetry data on a micro
SD memory card.
USB connection to read and write the model’s
memories as well as for making firmware updates.
• Integrated Graupner|SJ HoTT 2.4 GHz transmis-
sion system
• The high-speed primary processor is used for data
transfer, ensuring ultra-fast response times.
• Maximum interference immunity made possible by
optimized frequency hopping through as many as
75 channels and wider channel spread
• Intelligent data transfer with correction function
• Over 200 systems can be used simultaneously
• The HoTT technique of bidirectional communica-
tion between sender and receiver, as well as the
fastest possible transmission rate (10 ms) assures
extremely short reaction times.
• Modulation can be switched by software: when
necessary, you can switch from “HoTT” to “EXT.” or
“SP.” by pressing a button.
• Case incorporates integral patch aerial
• Transmitter features integral slot for SD and SDHC
memory cards, formatted to FAT or FAT32, for
saving log files, model programming data and sup-
plementary functions such as transmitter firmware
updates.
• Transmitter features alternative method of battery
charging via the USB socket.
• 6 different languages (Dutch, English, French,
German, Italian and Spanish) available per soft-
ware update. For the availability of a given lan-
guage, refer to the download area.
• Simplified arrangement of operating elements,
such as joysticks, external switches, proportional
controls and trim levers as control functions
• CONVENIENCE MODE SELECTOR to simplify
changeovers between operating modes 1 … 4
(e. g. throttle left/throttle right)
• Extremely wide receiver operating voltage range
of 3.6 V to 8.4 V (functional to 2.5 V)
• Fail-safe, free channel assignment (channel map-
ping), mixer functions and all servo settings are
