The transmitter

The transmitter Graupner mc-28 HoTT is the model for advanced model pilots. 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 temperature calibrated hall sensors gimbal sticks offer an outstanding durability and reliability.
Two wide, contrastful displays inform you at any time about telemetry data and parameters and they allow a quick and easy programmation.

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.

The receiver

The receiver Graupner GR-18 is one of the most successful receiver of Graupner range. the small, lightweight, with its only 12 grams, features 9 channels and offers through its two antennas a constant connection (antenna diversity).
Thre GR-18 transfers, without any additional component, voltage and temperature of the receiver so as signal strenght to the radio. The warning thresholds can be easily programmed through the transmitter.
The receiver is featured as standard with the gyrosoftware for airplanes and helicopters models, which are perfect for models of airplanes with gyro function and helicopters with flybarless.
Through update it is possible to upgrade the receiver to a flight controller for racecopters and 3D copters.
The setting is very easy to carry out through the telemetry in the transmitter, thus eliminates any interface for settings as PC, App and so on.

Integrated Bluetooth® v2.1+ EDR module with 115200 Baud for the use of Graupner HoTT Viewer for Android™ (Firmware >=2.2) to display telemetry data and announces on your smartphone.
The language outputs can be output in a timed manner.
The warnings can be defined in the smartphone.
Furthermore, a Bluetooth® v2.1+ EDR headset can be connected directly without a smartphone.

You will find the latest software and firmware in the section "Service / Help" under "Updates".

The Graupner Shop offers you a wide range of accessories and spare parts for your remote control system and your models.

  • 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.
