The Graupner GR-24 12-channel 2.4 GHz receiver is designed to provide reliable communication with Graupner HoTT radios across various applications, including large-scale warbirds and sailplanes. This receiver offers constant real-time monitoring of receiver voltage, temperature, and signal strength, which are transmitted back to the radio without requiring additional sensors. The GR-24's dual, full-range 2.4 GHz diversity antenna system ensures optimal signal reception and reliable telemetry data transmission, contributing to a safe and secure flight experience.
Key Features
Dual 2.4 GHz Diversity Antenna System:
- Continuously hops to the better antenna signal for optimal reception.
- Uses the last antenna for telemetry downlink transmissions to ensure reliable return channel data.
Real-Time Telemetry:
- Monitors receiver voltage, temperature, and signal strength in real-time.
- Transmits telemetry data directly to the radio without additional sensors.
Enhanced Operating Reliability:
- Up to 75 channel hopping for extreme reliability and immunity to external interference.
- Broad voltage range of 3.6 V - 8.4 V (functional to 2.5 V) ensures safe operation during voltage fluctuations.
- Increased receiver input sensitivity provides a vertical range of up to 4000 meters.
Ease of Use:
- Dual power connections for redundancy.
- Wireless setup and access technology.
- LED indicator for operating status.
- Easy front access for servo connections.
Programmable Settings:
- Fail-safe, hold, OFF, and standard programmable directly from the radio or receiver (channel 1: fail-safe; all others: hold).
- Programmable warning thresholds for low voltage and temperature extremes.
- Real-time wireless flight data recording.
Digital Output:
- Supports digital outputs (SUMD, SUMDV3, SUMDIN, SUMO, SUMI, SBUS) for flight controllers like V-Stabi, Microbeast, Brain, Bavarian Demone, 3Digi, and Naze.
- Selectable frame rates between 10ms to 20ms.
Compact and Lightweight Design:
- Easy integration into various model setups due to its compact and lightweight build.
Conclusion
The Graupner GR-24 is an advanced receiver that combines reliability, real-time telemetry, and ease of use, making it suitable for a wide range of applications. Its dual diversity antenna system and broad compatibility with digital flight controllers ensure reliable performance and optimal signal reception, providing pilots with the necessary data for a secure and enjoyable flight experience.
