The small and light FrSky X4R-SB receiver can be used either as a normal 3-channel receiver or as an S-BUS with 16 channels. Thanks to the telemetry, the receiver can trigger an alarm in the event of undervoltage and poor signal reception (e.g. at the end of the range). Telemetry sensors are connected directly via Smart Port: voltage, current, GPS, barometer, temperature, speed, etc. Threshold values ​​can be set in advance, which emit an alarm signal if they are exceeded or not reached! With the RSSI interface (Received Signal Strength Indication), the reception strength can be monitored with a corresponding OSD during FPV flight. The FrSky X4R-SB offers a long range of more than 1.5km. An analogue telemetry connection and a digital data interface (e.g. for the sensor hub), as well as the updateable firmware are also available. The receiver is compatible with the FrSky 2-way telemetry modules and of course also with the Taranis X9D.

    Very nice machine. With Lightburn very easy to work with it.

  2. Girish Saxena (verified owner)

    The machine came a few days earlier than stated. Very well packaged and the installation also went smoothly. After I executed the commands and calibrated the device, everything went as it should and the machine correctly found the position of the laser head. I hope that it will remain stable in the future and that the values will remain as it is calibrated. Everything works correctly I am really impressed with the performance of the machine and the results of the laser work.
