MX-20 Graupner HoTT Computersystem 2,4GHz Graupner 33124.16.FR

Fernsteuerung mx-20HoTT 12-Kanal FR Graupner 33124.16.FR Description
The mc-20 HoTT with its 12 control functions can give experienced RC model builders control over virtually any model. The use of Graupner HoTT 2.4 GHz transmission technology safeguards high functional reliability through bidirectional communication between transmitter and receiver supporting integrated telemetry, voice output via headset connector and ultra-fast response times.
The transmitter has 24 model memories. Programming is simplified by a programming technique implemented with capacitive touch buttons. A high-contrast, 8-line blue-illuminated graphic display ensures perfect presentation of all parameter settings and telemetry data. It is possible to store telemetry data and an extension of model memories on a micro SD memory card.
USB connection to read and write the models memories as well as for firmware upgrades.

Age recommended by manufacturer: 14 years and up

• Storage of telemetry data with date and time
• Servo cycle times of 10 ms can be selected for digital servos
• Ultra-fast response times due to direct and reliable transmission of data from the main processor to the 2.4 GHz transceiver. No additional delays due to detours viaa module processor.
• Short antenna, collapsible
• Operating and programming are similar to the proven concepts implemented in the mx-24
• A high-contrast, blue-illuminated graphic display ensures perfect control of parameter settings such as model type, model memory, timers and operating voltage.
• 12 control functions
• Free assignment of all switches
• 24 model memories
• 7 switches/keys , including 2 3-stage-switches, 3 2-stage switches, 2 keys, 3 analogue switches already installed
• Modes 1 to 4 freely selectable
• CAP TOUCH operating elements with key lock function to prevent unintentional operation.
• CAP TOUCH change of display from the main menu to the telemetry main menu via ESC.
• Numerous telemetry displays, programming functions and evaluation functions are presented directly on the transmitters screen
• Voice output can be called up via freely programmable switches
• Extensive programs for fixed-wing and helicopter models
• Swashplate limiter
• "Monitor" switch to check all switches and control switches
• 12 freely programmable mixers for fixed-wing or helicopter models, each with freely selectable input and output functions, including: 4 curve mixers, 5 point curve technology in 1 % increments, easy to adjust curve values at up to 5 points for throttle, pitch, tail or other non-linear actuations. The processor in the CPU employs an ingenious method of calculating polynomial approximations for truly-rounded, ideal MPC (multi-point curve) mixer curves.
• 7 flight-phase programs can be individually adapted for each model and given a name. The switchover time is programmable separately.
• SUPER SERVO menu with a perfect overview of all servo setting data and simple parameter correction for 4 "levels" (direction of rotation, mid-point setting, separate servo travel on both sides and separate travel limiting on both sides for 12 servos with a total of 72 possible settings)
• SUPER-DUAL-RATE, EXPO and EXPO/DUAL-RATE menu with 36 possible settings for 3 servo functions and 7 flight phases.
• Highly practical multi-function menu for fixed-wing and helicopter models. Entry of the number of aileron and flap servos automatically programs all necessary mixer functions in the multi-function "Wing mixers" menu. Differential aileron mixer, butterfly mixer, dual-flap mixer, automatic gyro set function and other special functions
• Helicopter swashplate mixer for 1, 2, 3, or 4-point steering.
• Fail-safe for 12 servo functions
• Convenient timers menu. Stopwatch system, alarm timer, countdown timer, laps counter, etc. Two timers and one lap counter/timer can be displayed at the same time.
• Stopwatch with history: in addition to the lapcounter there is a time 1 which captures the ON time and a time 2 which records the ON and OFF times separately.
• The transmitters operating time timer is automatically reset to zero by the battery charging process.
• Flight phase switch assignments: now 6 switches, 2 with priority function. Every switch combination can be named freely. This makes the number of flight phases independent of the number of flight phase switches.
• Linearising switchplate servos: electronic compensation for non-linear travel of swashplate rotary servos.
• Tail type normal, V-tail, Delta/flying-wing and 2 EL Sv 3+8 (which immediately makes 2 coupled elevator servos available without using free mixers or dual mixers)
• Flap count up to 4 AIL/4 FL: Full support of 8 wing servos, now even without use of free mixers.
• Flight phase switching delay, can be switched off: the delay time can be switched off for individual channels flight phase by flight phase (e.g. for motor off in electric models or to activate/deactivate helicopter head lock).
• 16 phase names:.
• Fixed-wing mixer: New concept for the multi-flap menu to simplify settings of up to 8 wing servos on a flight-phase-specific basis in a comprehensible manner without requiring the use of free mixers.
• Number of flight phases: (fixed-wing: 7, helicopter: 6 + AR)
• Phase trim
• Switchable Snap-Flap mixer EL => FL with a new offset function for easy course corrections and fast turns
• 3 ring limiters for Voith-Schneider and similar drives
