Graupner MC 20

12 Channel 2.4GHz HoTT Transmitter


  MC-20 is Hand-held, tray-type transmitter with 12 controls functions and a new internal patch aerial.
  MC-20 HoTT transmitter enables advanced RC model builders to control nearly any model. The use of the
Graupner HoTT 2.4 GHz transmission technology ensures high functional reliability through bidirectional
communication between sender and receiver, with integrated telemetry, voice output via speaker or headphone
output, and ultra-fast controller response times.

  The transmitter has a 24-model memories and features simple programming setup with capacitative touch keys.
Two high-contrast, 8-line blue-lit graphical displays ensure a perfect display of all parameter settings and
telemetry data. It is possible to store telemetry data and expand the model memories on a micro-SD memory
card. USB  connector for readout and storage of model memories and for firmware upgrades.

Key Features
  • FHSS, frequency hopping via up to 75 channels
  • Range test and warning function
  • Extremely broad receiver operating voltage range from 3.6 V to 8.4 V (functional to 2.5V)
  • Numerous failsafe functions
  • Integrated telemetry display with 8 x 21 characters/ 128 x 64 pixels
  • Micro-SD card slot for storage of telemetry data, similar to a black box and to add model memories,
MP3 player, and for firmware updates
  • Wireless teacher/pupil function 
  • Binding of any number of receivers for channel expansion (maximum of 16 channels) The last receiver bound
sends the telemetry data.
