FrSky R-XSR–New ultra mini receiver

FrSky has recently announced their new ultra mini receiver – FrSky R-XSR. If you are using FrSky transmitter like Taranis X9D or Taranis Q X7 you should have a look at this tiny new receiver.

According to FrSky, the new R-XSR receiver is “the evolution of FrSky full range XSR receiver”. However, the new receiver is 1/3 size and 1/3 weight of the XSR receiver. It could perfectly replace the FrSky XM+ receivers we are using. Compared to those the new mini receiver support telemetry and Smart Port.


Here is a quick comparison of both mini receivers:

Size 16mm x 11mm x 5.4mm 21.5mm x 12mm x 3.5mm
Weight 1.5g 1.6g
Number of channels 16 (16 SBUS / 8 CPPM) 16 (16 SBUS / 8 CPPM)
Operating Voltage Range 3.5~10V 3.7V~10V
Operating Current 70mA @ 5V 30mA @ 5V
Full Range Yes Yes
Telemetry and Smart Port Yes No


The R-XSR receiver is a bit smaller and a bit lighter than the XM+ receiver. Additionally, you can see the telemetry data (like battery voltage) on the display of your Taranis transmitter.

The R-XSR is available already at and should be available soon for international buyers at Banggood.

  1. Minimum input voltage is 3.5V for the R-XSR, your article incorrectly lists 3.0V.

      Hey Max, yeah it is available in some European stores already. What do you mean with “slave”? What is the purpose you want to use it? Best, Sergey

        Hey Sergey,
        thanks a lot for you reply.
        In the manual they write about a master and slave receiver for the redundancy function. The R-XSR is the master and any other receiver is the slave.
        I was wondering if I should use the XM+ or better go for a 2nd R-XSR.
        Thank you.

          Hey Max, yeah got it. You can use the XM+ as a slave receiver, yes. If you check the manual, it is even recommended to use the XM+. Grüße, Sergey
