GRAUPNER GR-24L 12-CHANNEL RECEIVER
Graupner’s unique HoTT protocol supports real-time bidirectional data transmission without using external devices and is suitable for any type of aircraft. You get realtime info that monitors receiver voltage, receiver temperature, and signal strength. The receiver uses up to 75 channels of hopping for excellent reliability and stray-signal interference. The broad voltage range of 3.6 to 8.4 volts means you’ll never have a brownout, especially since you can program warning thresholds. Other HoTT receivers sport the same features, and additional modules are also available. Even better, they are affordable— the 12-channel receiver is only $79.90!
The dual-antenna GR-24 2.4GHz receiver comes with the radio system.
