Specially designed to work only with our X-8N and X-8E surface radios, the Graupner GR-8 is a 4 channel 2.4GHz receiver.  Compatible with our new SUMD V2 technology, it supports Graupner’s exclusive HoTT telemetry protocols and can be programmed to output frame rates as low as 1.5ms for ultra-fast response time.

Its compact size and top connector access makes the GR-8 well suited for any type of installation, especially where space is limited. The GR-8 HoTT receiver makes telemetry speed controllers and telemetry servos easy to install and is packed with standard features such as telemetry for signal strength, receiver voltage, temperature and main pack voltage (available with sensor P/N S8362, sold separately). With a range of up to 1000 meters and full spectrum utilization the GR-8 guarantees a reliable connection even at the most congested race tracks.

Receiver works very well. If you are racing a nitro vehicle you will want to use this receiver. It has enough ports for both servos, transponder, battery and temperature sensor. The other nice thing about this receiver is that it outputs the external temperature sensor data to one of the main screens in Fahrenheit. The GR-4 receiver you have to go to the telemetry menu and it only displays in Celsius.

These receivers are GR 8!
I have 6 of these receivers in my R/C cars that I race every week and they are great. These devices are very user friendly, they bind fast and easy and the range is exceptional. I have never lost a signal. The X-8N transmitter is easy to use, easy to understand and the grip is comfortable for driving. When I needed assistance the customer service was great and they never gave up until the problem was solved.
