OVERVIEW

The reliable and simple Graupner GR-32L offers redundancy without the complexity of installing multiple receiver satellites or additional hardware.  With its 16 channels, dual receiver hardware and four antennas the GR-32L provides installation simplicity that is unmatched in the industry. With Graupner HoTT 2.4 GHz technology all real-time information regarding receiver voltage, receiver temperature and signal strength is always monitored and transmitted back to the radio without the need for additional sensors.

The dual receiver has two complete and separate receiver sections as well as additional hardware antenna diversity. Signal quality is constantly monitored and automatically switched over to the better antenna signal, except during telemetry downlink transmissions in which the last antenna used for receiving is utilized. This ensures that the return channel data is transmitted via the better positioned antenna, assuring you that telemetry information is always available for a safe and secure flight.

The receiver has a bus connector for additional telemetry sensors such as GPS, ESCs, Vario (and many others) to further enhance the value of your radio system providing pilots with valuable real-time information to improve flight operations.

The Graupner GR-32L can be used in combination with digital flight controllers via output digital signals in SUMD or SUMO single wire installations.  The 6 separate battery inputs transform the GR-32L into an excellent power source for high-load servos eliminating the need for external power distribution systems.
