The MX-20 12-HoTT radio-control is one of the most advanced ones in its category. The use of Graupner HoTT 2.4 GHz transmission technology ensures high reliability through bi-directional communication between transmitter and receiver with integrated telemetry, voice output via the headphone output and ultra-fast response times.

The station has 24 model memories. Simplified programming programming technology with capacitive touch buttons. High-contrast, 8-line blue backlit graphic display ensures perfect display of all setting parameters and telemetry data. Storage of telemetry data and expansion of the model memory on a micro-SD memory card possible. The channel signal is resolved with 12-bit in 4096, enabling an extremely sensitive control behavior.

USB port for reading and saving of model memories and for firmware upgrades.

• Mode 1-4 selectable
• CAP-touch control panel with key lock function prevents accidental operation.
• Cap-Touch display change from the main menu to the telemetry main menu with ESC.
• Numerous telemetry display, programming and analysis functions directly in the transmitter display
• voice output available via programmable switches
• Extensive programs for surface and helicopter models
• switch "monitor" to check all the switches and control switches
• 12 mixers, programmable for surface model and helicopters, with freely selectable input and output functions, 4 curve mixers 5 point curve technology in 1% steps, easy to set and adjust curve values for max. 5 points for throttle, collective pitch, tail rotor or other non-linear ways. The computer calculates the CPU with an ingenious polynomial approximation ideally rounded MPC (multi-point curve) mixer curve.
• 7 flight phase programs can be customized for each model and name, the switching time is programmed separately.
• SUPER SERVO menu provides a sophisticated overview of all servo adjustment and correction for 4 simple parameters (direction of rotation, center position, separately for each side separately for each side and servo travel limit for 12 servos with a total of 72 set)
• SUPER DUAL-RATE, EXPO and EXPO-/DUAL-RATE Menu with 36 set-up variations for three servo functions and six phases of flight.
• Practical and optimized multi-function menus for fixed-wing and helicopter models. Entering the number of aileron and flap servos automatically programs all the appropriate mixer functions in the multi-functional wing menu. Aileron differential mixer, butterfly mixer, dual-flap mixer, Automatic gyro set function and other special features
• Helicopter swashplate mixer for 1 -, 2 -, 3 - or 4-point linkage.
• Fail-safe monitor for 12 servo functions Comfortable Watches
• Stopwatch system, alarm timer, countdown timer, lap counter, etc. 2 and 1 lap time displayed.
• Stopwatch with history: In addition to the lap counter, there is a one time, which captures and records a time 2 turn-ON and OFF times separately .
• Transmitter operating timer is determined by the battery charging process of the transmitter is automatically set to zero.
• Switch assignment of flight phase switch: Now 6 switches, 2 with priority feature. The name of each switch combination can be selected. This limits the number of flight phases of the number of flight phase switches.
• Linearization swashplate: Electronic compensation of the nonlinear path of rotating swashplate servos.
