FrSky X4R-SB - RX w/ SBUS

The FrSky X4R-SB is the perfect companion for the FrSky Taranis. Smaller than a matchbox and lighter than a lighter (ba dum tsss), it’s packed with features that make it the most logical choice for a serious multirotor pilot. With extended range and increased reliability, you’ll be able to fly farther without glitches. If you do get near the range limit, a low signal alarm will make sure you don’t lose your quad.

One of the key features that make this receiver stand out - the ability to transmit telemetry data such as battery voltage, amp draw, and other aircraft information back to the radio in your hands. This is especially useful for FPV pilots when combined with the FrSky Taranis’ spoken feedback system.

  • Weight: 6 grams
  • Size: 40x23x6mm

    No wiring instructions

    Could b better if x4r came with some sort of pinout. U can find out online but for beginners it’s nice to refer to a pinout. Outside of that this receiver is great. Range and features are top notch

    My goto receiver

    Posted by MaEtUgR on Apr 26th 2018

    I use taranis tx only. This receiver even allows multi channel output for flying wings and has telemetry + S-BUS which are a must for a racer today. But by now there are systems like TBS crossfire that allow for longer range and less latency, so if you can afford it might be worth to have a look.

    You can't beat the seamless integration, binding and performance. Telemetry works great as well!

    Awesome Receiver

    Posted by CavanFPV on Mar 28th 2017

    The X4R is small, light weight, and well built. I love its speed and i have full confidence flying with it in my quad. Also has an easy setup and is very easy to use.

    The Standard In Flight

    Posted by Logan Ilczyszyn on Feb 16th 2017

    This is a staple for any quad, but your supporting a great group buying from here. In general they tend to have the best or equal to the lowest price anywhere else. I only wish they started carrying the xsr. Much more convenient with the connector and simple mod to get the same range. If they sold those here, I wouldn't shop anywhere else for my radio gear. But this works too. :)

    As Described

    Super fast shipping as always, installed it but that's about it. been busy with HAM testing, have not tested range against the X8R I got in the taranis kit from here. I should prolly conformal coat it too.
