Product description

With the Graupner HoTT 2.4 GHz technology used, the Graupner GR-12L receiver features state-of-the-art components and software.

  • Antenna diversity.
  • The HoTT technology uses up to 75 channels. This ensures extreme operational reliability and insensitivity to external interference.
  • Receiver voltage, temperature and signal strength are transmitted without additional sensors. Failsafe and Hold are programmable. The input sensitivity of the receiver and thus the range could be significantly increased.
  • The small and extremely light receiver is used with SUMD, SBUS or SP2048 on Copter Flight Controls or Flybarless systems.
  • The RSSI value can be output with SUMD, SBUS or SP2048 on channel 8, 12 or 16.
  • 3 additional solder terminals for K2-4 for servo pulse output or level output (0V or 3.3V max. 4mA) for switching LEDs or transistors.
  • The GR-12L receiver has a wide voltage range from 3.6 V - 8.4 V (operable up to 2.5 V) for high reliability, even with voltage fluctuations.
  • A red LED clearly indicates the operating status of the HoTT receiver at all times.
  • In our Graupner online shop you will find the right accessories and spare parts for model making - the right remote controls, chargers, servos, NiMH and LiPo batteries.
  • Hole spacing 20 mm x 20 mm. Hole diameter 3 mm.
  • The sides can be easily removed so that the receiver has the dimensions 25 mm x 15 mm x 4 mm.
