With reliable, inexpensive and a great line of receivers, FrSky has always been on the forefront of the radio game, spooling out new receivers every now and then. The FrSky X XSR is one of those receivers that had been used as the de-facto choice of receiver for FrSky receivers till recently when it was overshadowed by the newer receivers like the R XSR and the R9 series.

In this article, we will be looking into the X XSR receiver and its set up with an X9D/ Plus radio to get it working. Read through and we will conclude with whether this is worth the money in 2020 and beyond.

Formfactor and Outline

 

The FrSky X XSR receiver is smaller than the previous generation of receivers that precedes it. It goes away with the plastic casing to reduce bulk and slight weight reduction. FrSky has only included tiny 5 pin connector and has removed all the big servo headers. Despite this small size, the FrSky X XSR has a Smart port telemetry pin, CPPM out the pin and also SBUS out pin! Basically, it has got you completely covered as far as pinouts and connectors are concerned. The FrSky X XSR is basically a scaled-down version of the X8R receiver.

Step 1: Wiring and powering on your receiver

As all other electronics in your quad, the FrSky X XSR receiver must also be powered and connected to a flight controller or a power system on the UAV. While binding we'd like to make sure we offer a stable power supply to the receiver in order to make sure it turns on without hiccups.

The FrSky X XSR receiver takes somewhere  between 4 to 10V DC as input power and consumes close to around 100mA during operation and so it is vital to power the receiver with a supply capable of providing this current. Most of the 5V outputs on your flight controller will be capable of providing the required power for it. You can easily use the 5V pad on your flight controller for an equivalent .

The above picture depicts the wiring output of the FrSky X XSR receiver. The +5V pin can spend to 10V although it's recommended you employ only 5V from the flight controller or PDB alongside the bottom wire.

Once you've got the required wiring, power the FrSky X XSR receiver to see whether it activates or not. The Red/Green LEDs should start blinking if it's power. If you've got the LEDs blinking, it means the wiring was correct and therefore the receiver has powered on.

Step 2: Bind mode for the Taranis radio

For this step, you may use any Taranis radio of your choice. I’ll be showing you how to do it on an X9D+ transmitter from FrSky.

First, turn on your transmitter.

Scroll to the  “Model Setup” page by pressing the menu button.

Scroll up there in the menu till you discover the “Internal Module” option.

Under that, select the following:

  1. Mode - D16
  2. Channel Range - CH1-16
  3. Receiver Number - Any unused number
  4. Fail-Safe Mode - Any option you prefer

 

After the above settings are entered, select the [Bind] option then the TX will activate its binding mode with the above parameters and begin trying to find a close-by binding receiver to connect and pair with. You will also hear an audible “chirping” sound from the TX to offer you a confirmation that the radio is prepared to bind with the receiver.

Step 3: Putting the FrSky X XSR receiver into Bind Mode & binding with the transmitter

Now that you simply have put your radio into the Bind Mode, it's time to place the FrSky XSR receiver into the Bind Mode also . Unlike the set-up we went through on the FrSky radio, the FrSky XSR receiver is sort of easy to place into bind mode.

  • First, confirm your FrSky XSR receiver is turned off.
  • Press and hold the “F/S” button on the FrSky XSR receiver at the corner of the receiver.
  • While the button is being pressed, power on your receiver. The RED LED on the receiver should start blinking fast - indicating it's in Bind Mode
  • Once that's done, during a few seconds (or immediately ) the GREEN LED on the FrSky XSR receiver would also illuminate - indicating that the receiver has been bound with your transmitter radio. You can close up your receiver now then exit the binding mode on the transmitter.
  • Power on your FrSky X XSR receiver again and verify whether the GREEN LED is solid. If it is, then it means you've got successfully bound the receiver to the Taranis transmitter. You will also see the RSSI range on your transmitter too if you've got configured that.
  • If you've got not been ready to bind successfully, check the subsequent points:
  • FrSky XSR and Taranis radio are using an equivalent firmware - EU/Non-EU
  • Correct mode - D8/D16
  • Bind button on the receiver isn’t damaged 

Conclusion

In this article, we have seen about the FrSky X XSR receiver, its specifications and how to connect it to your flight controller and set it up on your Taranis radio. Although this is a great receiver, this is heavily outdated and has been replaced with newer receivers such as the FrSky R-XSR and hence I would not suggest you purchase this anymore.
