Hello everyone, I’m Mirko, and today we do a comparative among Frsky receivers These are the 2.4ghz receivers recommended for FPV drones if you want to buy them you will find all the links in the description Starting from the left we have: X4R-SB; XSR; XM+ and R-XSR They are all compatible with XJT module in D16 mode so they can be used with both Taranis and Horus The firmware of these receivers can be updated easily via the radio itself and we can choose to install the European or non-European version. These receivers support the SBUS protocol it is a low latency digital protocol which sends all the channels into a single signal cable. The Sbus has become the standard for FPV drones old protocols like PPM and PWM they are obsolete and are no longer used.

The maximum number of channels with the SBUS is 16, sufficient for each configuration need. All receivers except for XM+ have the SmartPort available. SmartPort is a two-way transmission interface developed by Frsky. With SmartPort, we read the flight controller sensors and we receive the telemetry data on the radio. In addition to receiving data with SmartPort we can also send them. For example via Lua Script we can transmit from the Radio to the Flight controller the PID configuration All four receivers provide us with the RSSI signal.

However in the XM + we can receive it only via flight controller OSD Frsky declares these receivers as full-range, this means that they have 1.5km of reach. However we talk about theoretical limits since distance is influenced by external factors such as the presence of obstacles between the radio and receiver Now let’s see the weight and size of the receivers. The width of the X4R is 20.7mm the length is 30mm The weight is 3.2g Total antenna length is 15cm the exposed part is 31.2mm The width of the XSR is 19.1mm the length is 25.7mm The weight is 3.2g Total antenna length is 9cm the exposed part is 25mm The width of the XM + is 11.9mm the length is 21.9mm The weight is 1.2g Total antenna length is 9cm the exposed part is 22mm The width of the R-XSR is 11mm the length is 16.4mm The weight is 1.2g Total antenna length is 9cm the exposed part is 22mm To conclude, we see receiver pros and cons The X4R has proven over time a solid and reliable receiver.

Good possibility to replace the antennas in case of damage. Weight and size do not play in X4R favor, this receiver is not suitable for smaller buildings. Even the XSR is a valid choice and offers us weight and smaller in size than X4R. His biggest cons can be considered have the antennas soldered directly into the PCB. This makes it very difficult to replace antennas for beginners. The XM + is one of the most compact receivers of Frsky line. Here too we have the possibility to replace easily the antennas in case of damage. The absence of SmartPort is definitely a cons even if we have to say that the modern flight controllers, via OSD, they give us all the information we need on the screen.

Of the four it is the one with the lowest cost appearance to keep in mind if we want to assemble a low-cost drone. To conclude we have the latest arrival at Frsky, the R-XSR. This receiver contains all the advantages of the others: low weight and size, possibility to replace antennas and SmartPort. the initial R of the name stands for Redundancy and gives us the possibility of connecting a second receiver. However this feature is not essential for racing or acrobatic miniquads. And what do you think? Which is your favorite receiver? Leave a comment and let me know your opinion.
