The Graupner GR-24 PRO HoTT (Hopping Telemetry Transmission) 2.4GHz 12 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. Plus a slew of added sensors and telemetry in a very sleek housing make it extremely powerful. Packed with a 3-axis Gyro, three independent accelerometers, 3 magnetic compass heading controllers, and an onboard variometer for altitude determination, this is by far the most value priced, capable receiver on the market, bar none! By utilizing the receiver’s telemetry functions, telemetry data such as input and output signal strength, receiver temperature, battery capacity, 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-24L receiver is lightweight, has a small form factor, and is well priced. Its small size, low weight, and high quality make it ideal for use in larger or higher channel models requiring additional stability and altitude control. Plus, the use of dual antenna leads make it the lightest, most reliable combined 12 channel receiver and gyro package in the industry. Other Graupner telemetry sensors can be plugged in through the dedicated “T” telemetry port via a Y-lead for passing further real-time, in-flight data to the transmitter.
HOPPING TELEMETRY TRANSMISSION 2.4 GHz technology, two-way telemetry, updatable firmware, 3-axis gyro, accelerometers, heading indicators, and vario
Servo connections in the front panel. All servo/signal connectors are JR style and compatible with both analog and digital servos.
Receiver supports SUMO/SUMI/SUMD signal output on Ch 8 for convenient use of gyros/control boards, includes a programmable failsafe function
Refresh rate (PERIOD) of 10 and 20ms programmable—20 ms is recommended for use with analog servos to avoid servo “growl”
Small form factor, two 5.5” antenna leads ideal for intermediate and large models and use as a satellite receiver to reduce servo wiring runs
