The Graupner GR-12L HoTT (Hopping Telemetry Transmission) 2.4GHz 6 Channel receiver is designed with Graupner's unique telemetry technology, supporting bi-directional data transmission to give the user real-time sensor data. The use of up to 75 frequency hopping channels ensures extreme operating reliability and immunity to external interference. By utilizing the receiver’s telemetry functions, telemetry data such as input and output signal strength, receiver temperature, and voltage are transmitted real time in-flight to the transmitter for onscreen review and post flight analysis. Featuring a versatile one-chip integrated RF design and MCU (MicroController Unit) chip, the GR-12L receiver is lightweight, has a small form factor, and is exceptionally affordable. Its small size, low weight, and high quality make it ideal for use in small or low channel models. Other Graupner telemetry sensors can be plugged in through the Ch 5 port via a Y-lead for passing further real-time, in-flight data to the transmitter.
HOPPING TELEMETRY TRANSMISSION 2.4 GHz technology with two-way telemetry, updatable firmware—the newest features always! Two receivers included!
Servo connections in the front panel. All servo/signal connectors are JR style and compatible with both analog and digital servos.
The receiver supports generation of SUMO/SUMI/SUMD signal output on Ch 6 for the convenient use of gyros and control boards
Refresh rate (PERIOD) of 10 and 20ms programmable—20 ms is recommended for use with analog servos to avoid servo “growl”
Small form factor with a 5.5” antenna lead is ideal for small models and for use as a satellite receiver to reduce servo wiring runs
