This receiver comes pre-loaded with ACCESS firmware, Non-FrSky Radios and FrSky radios with older ACCST versions will be rendered unable to bind. Please flash your RX with the legacy firmware in this link to remedy this issue.

Love the compact design of the XM+ but need full telemetry? FrSky listened and released the R-XSR to have the best of both worlds!  The R stands for "Redundant" for its ability to be able to run a slave Rx if that's your thing... 

The FrSky ultra mini receiver R-XSR is the evolution of the popular full range XSR receiver. The R-XSR is a standalone receiver with all the functionality of the full size XSR (including telemetry), but at 1/3 size and weight of XSR receiver. The RXSR also has an integrated diversity with 2x antennas for a solid RC link, and the IPEX connector makes it convenient to replace antennas.
