    An upgrade to the MC-26 this system features hall sensor gimbal sticks and upgraded battery, bluetooth module and other upgrades.

    The mc-28 adapts itself to almost all models. 16 function controls, 120 internal model memories, integrated telemetry and voice messages so as the fast and reliable bi-directional transmission of the Graupner HoTT 2,4 GHz technology, it all makes the mc-28 a true allrounder.

    The mc-28 transmitter features an internal circular polarized patch antenna with very high range and reliability.
    Furthermore the digital and temperature calibrated hall sensors gimbal sticks offer an outstanding durability, reliability and precision.
    Two wide, high contrastdisplays inform you at any time about telemetry data and parameters and they allow quick and easy programming.

    The switches and buttons of the transmitter can be freely assigned thus making them customizeable. There are also 12 mixers available. 8 switch-phase programs with announce function can be adjusted and named for every model.

    Thank to the micro SD card and the micro USB port telemetry data and model memories can be imported and exported. Also firmware updates can so be played without any complication.


    MC-28 Features

      Microcomputer remote control set implemented with the very latest 2.4 GHz Graupner HoTT technology

      Internal circular polarized patch antenna

      Dgital and temperature calibrated hall sensors gimbal sticks
      Ring limiter and channel sequencer
      Bidirectional communication between transmitter and receiver
      Wireless T/P function
      6 different languages (German, English, French, Italian, Spanish and Dutch) available via software update. For the availability of a given language, go to the Download area.
      Storage of telemetry data with date and time
      Servo cycle times of 10 ms can be selected for digital servos
      Ultra-fast response times through direct and reliable transmission of data from the main processor to the 2.4-GHz transceiver. No additional delays due to detours via a module processor.
      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
      10 switches/keys , including two long 3-position switches, four 2-position switches, 2 long keys, 2 keys on the rear and 2 slider regulators as well as 2 side rotary controls
      Modes 1 to 4 freely selectable
      CAP TOUCH operating elements with key lock function to prevent unintentional operation.
      Numerous telemetry, programming and evaluation functions are presented directly on the transmitter’s 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 wing or helicopter models, each with freely selectable input and output functions, including 4 curve mixers with 5-point curve technology in 1% increments, resulting in curve values that are easy to set and adjust 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 menu with 36 possible settings for 3 servo functions and 6 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 lap counter there is a time 1 which captures the ON time and a time 2 which records the ON and OFF times separately.
      The transmitter’s 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
      Channel sequencer for 3 channels for folding motors and landing gear doors
      Logical switches
      Trim memory
      Multi-channel function to expand channels for up to 14 additional channels
      Music player and internal speaker for voice output and music
      Swapping of servo assignment at receiver output on transmitter side and receiver side
      PPM signal adjustable at the data output
      Model memories of the mx-20 can also be loaded directly into the mc-20. To do so, simply copy the model memories on the PC to the appropriate directory. Then the switches and controls must be newly assigned because of the different hardware.
