Frsky Receivers RX Options for Mini Quad

There are a whole range of Frsky receivers on the market and we have rounded up the ones suitable for mini quads and micro quads in this article. We will explain the differences in spec and hopefully it can help you choose the one for your next build.

The radio receivers mentioned below are Frsky Taranis compatible RX, that work with Frsky radio transmitters (TX) such as the Taranis X9D, X9D Plus, Q X7, Horus and X9E .

There might be other 3rd party RX’s designed for Frsky radio system we have not covered in this guide, please let us know in the comment section.

How To use Frsky RX, tips and tricks:


d4r-ii receiver

  • Weight: 5g
  • Dimension: 40 x 22.5 x 6mm
  • Receiver Protocol: PPM – 8ch
  • Telemetry: Yes – non-SmartPort

The D4R-II is one of the oldest RX in the mini quad world. It was made popular because of the compact size, and support for PPM (it only requires 1 cable for 8 channels). However we now prefer SBUS receivers for the lower latency.


x4r-sb receiver

  • Weight: 5.8g
  • Dimension: 40 x 22.5 x 6mm
  • Receiver Protocol: SBUS – 16ch
  • Telemetry: Yes – Smart Port
  • Product Page

The X4R-SB has nearly identical size to the D4R-II. It was one of the most popular RX’s for mini quad because of the SBUS and SmartPort Telemetry supports, until smaller RX came along.


frsky xsr rx XSR frsky receiver size comparison

  • Weight: 3.8g
  • Dimension: 26 x 19.2 x 5mm
  • Receiver Protocol: SBUS – 16ch
  • Telemetry: Yes – SmartPort
  • Product Page

The XSR is a size/weight upgrade of the older X4R-SB RX. It has exactly the same capability as the X4R-SB, but it’s considerably smaller and lighter. However some owners of XSR claimed to have shorter range than the X4R, due to the incorrect length of active element in the antenna (the exposed part). Therefore make sure you check it’s cut to the correct 31mm length when you get yours.


Frsky XM RX  Frsky receivers size comparison - XM, XM+, XSR, X4R-SB

  • Weight: 1g
  • Dimension: 15 x 10 x 3.5mm
  • Receiver Protocol: SBUS – 16ch
  • Telemetry: No
  • Product Page

The XM RX is made for micro builds that don’t require full range. It’s one of the lightest and smallest RX in Frsky’s radio receiver line. However it doesn’t have telemetry, only a RSSI output.


Frsky XM+ RX 

The XM+ is a diversity version of the XM (having 2 antennas), which allows it to perform full range comparable to the X4R-SB and XSR. It also supports 16-channel SBUS, but no smart port telemetry, only RSSI output just like the XM.



  • Weight: 0.83g
  • Dimension: 13 x 17 x 5mm
  • Receiver Protocol: PPM – 8ch
  • Telemetry: No
  • Product Page

Third party micro size receiver designed specifically for micro brushed quadcopters. The antenna (copper trace) is etched on the PCB to ensure maximum durability and weight saving, but range is very limited.

I used the MicroFrX receiver in one of my builds.

FuriousFPV LR1000

  • Weight: 1.4g
  • Dimension: 23 x 14 x 4mm
  • Receiver Protocol: SBUS – 8ch
  • Telemetry: Telemetry Hub
  • For more detail

A light weight and compact RX by FuriousFPV to provide decent range for mini quads (spec states 1Km). Although this RX supports SBUS, only 8ch is available.

FuriousFPV LR1000 Diversity

  • Weight: 2.2g
  • Dimension: 24.5 x 14 x 4mm
  • Receiver Protocol: SBUS – 8ch
  • Telemetry: Telemetry Hub
  • For more detail

This RX has similar feature and spec as the LR1000, except it has diversity antennas for more reliable signal.
