    This is by far my favorite receiver to use with my Taranis transmitter. I always de-pin mine and direct solder the wires to make it smaller and lighter. Not much else to say about it, it just works and works well. My only complaint is the newer versions that are being shipped are using a different connector for the antenna cables and I bought a bunch of antenna replacement cables a while back because if you are flying a lot, you will damage the cables over time. I can't use any of those cables I bought on the newer X4R-SB units I've received this week. I can't find replacement cables anywhere for them either. For this reason, I am only giving this 4 stars. If they had kept the antenna connectors the same or documented what the new connector is called or where to get replacement cables, I'd have gladly given this a 5 star review.

    Overrated. Too much trouble to get it to work with a lost drone buzzer. Update: I purchased a new unit to use with my Omnibus F3 flight controller. Now that I understand how to use Betaflight to set it up the unit, most of my problems with the radio receiver are now resolved. The major flaw with the receiver is with the antennas. They break very easily so be careful with them. In addition, putting a replacement antenna on is a real pain. I ended up destroying my receiver when I pressed too hard trying to snap the antenna back on.

    This caused me to crash and break my new Runcam eagle fpv camera on my 185 racer. Range was maybe 30 or so yards and it dropped like a rock onto the concrete at full throttle ;( I am not a happy customer. Hope my motors and everything else is ok... Upon checking everything closely, I found the antenna to be loose which was the culprit. The receiver is working great and I was also able to also fix my fpv camera. Life is good!

    Had to buy these twice. First one was DOA. But once you get it working, absolutely fantastic!

    These seem to be hit and miss. Most work great, but once in a while you get one with range issues.

    nice receiver with the performance you expect from Frsky. A little big for your smaller FPV quads though. I put mine on a 210 where the weight saving isn't a big issue since the quad is so small and light as is.

    I read a few reviews and this rx seemed like the way to go with my setup. However, since they are made in China the quality of this 1 I received out of a thousand others, the antenna broke right off the board after a semi-rough landing. Thought they were a little more durable. This may only be me and a handful others but, I bought another and will try it again. Overall good product.
