News: Frsky XSR-SIM FPV Simulator Dongle

Tired of having a wire in the way when playing FPV simulators with your Taranis? Problem solved! FrSky recently released a Wireless USB Simulator Dongle – the XSR-SIM. It allows you to wirelessly connect your FrSky transmitter to the computer for racing drone simulators.

Where to Buy?

How Does XSR-SIM Work?

It’s actually pretty similar to using a flight controller + receiver combo, except the wiring and requirement is much simpler.

For Windows it should work straight out of the box given that the HID driver is pre-installed. for Mac users you will have to download the correct HID drivers first.

The XSR-SIM has a built-in receiver, so you will have to bind it to your Taranis or Horus radio.

According to Frsky, this dongle works with all popular sims such as DRL, Liftoff, Velocidrone, Freerider, FPV Air 2 and so on. You can also flash the firmware quite easily through the SmartPort interface if there are incompatibility issues with future sims.

Yes, it’s much cheaper to just run a Mini USB cable between the transmitter and computer. But sometimes you might want a wireless connection because having a cable can be quite inconvenient. It’s good to have options.


  • Size: 48.2 x 19.1 x 9.2mm
  • Weight: 6.2g
  • Low power requirement – around 55mA at 5V
  • Compatible with FrSky transmitters and module systems (Mode D16)
  • Supports up to 8 channels (has to be set up on transmitter’s input & mixer)

Can’t Bind to Radios?

For Binding instructions, check out the manual:

If you are having trouble binding it, usually this is a firmware problem, where your Taranis or Horus might be on FCC or LBT (EU) firmware but the XSR-SIM is on the other (don’t forget it has a receiver built-in!)

In this case you will have to flash the correct firmware through the S.Port just like flashing the R-XSR receiver. Download firmware from FrSky’s website here, it contains both firmware:

    Hi Oscar
    Your website is THE most resourceful place for all my questions. Thanks for your efforts!
    Since Google could not answer my question, I hope you can help me here. Got a XSR-USB running LBT firmware and a x9d with flex firmware but I fail to bind. Would flashing the rx with FCC resolve my issue?
    PS: Don’t wanna solder the pins if not absolutely necessary…

      Yea try flashing FCC firmware and see. It has nothing to do with the “flex” firmware which is just a OpenTX firmware.

    Hi, I have tanaris qx7. I put in xsr-sim to bind mode and on tanaris start binding mode, but still shines red and green diode. Whatˇs wrong?

    I’m trying to set this device with RealFlight8 and a Taranis 9xd Plus. When I calibrate, it shows channels 5,6,7 and 8 even through my Taranis puts out channels 1, 2, 3 and 4.

    If I can already use a USB cord to connect my QX7 to my Mac and use a simulator, is it safe to say that I already have the HID driver installed?

        It seems, from what I read that most OS X users are installing USB Overdrive, with limited success.

        For FRSky to say “…for Mac users you will have to download the correct HID drivers first…”, is pretentious! Who would know what the correct OS X HID drivers are, if not FRSky?
