The R-XSR arrived in good condition and was able to bind easily to the transmitter. No issues so far.

I spent the last 3 days trying to understand why my RX was binding but not communicating with my flight controller. Turns out a component was not included with my purchase that would have given me the clue i needed to resolve my issue and not destroy an included component to make it work.i received 2 pieces, the integrated circuit board with attached antennas that i wanted, and a set of cables i thought i needed. I did not receive anything else and per the page i purchased it, it was not part of the included pieces.You do need this inclided cable, you have to update the firmware on the IC before using it (dont use latest firmware, use 2nd oldest), this cable provides ability to update software, only.There is also a pinout diagram you will be shown that lets you know that your upload cable will not transmit data, neither telemetry or TX, as its wired wrong, and you can alter included cable to fix this problem, but it will no longer upload firmware once altered.Per Youtube videos this kit originally included a separate 5 pin adapter with cables in all 5 pins so you can make the appropriate cable for your TX. This is not included anymore, you are not warned that this is not there, or that you will possibly need it.Be warned that if you want to use this with your Taranis QX7, the most requested RX for this particular TX when I purchased in November 2024, that you have to update the RX to match your updated TX (but dont use the latest update, go back one) and then you have to modify the only cable offered because the SBUS pin is in the wrong position (move yellow cable to pin 4 from pin 3) for data transmission, and will only work for updating the RX.because they cant be bothered to send you one with updated RX (its several years old now), you need to be aware of this, and they get a 3 star review from me, even though the product is great once configured and working.

Solved: I have never had a single issue with FrSky products, Yes FrSky with a "R" until I met this little Rascal. Step one: move the signal wire to the correct position for SBUS Step two: flash the critical ACCST Firmware update as per the FrSky instructions, NUTS! The receiver no longer Binds to my radio?? Several hours later, multiple searches and video's I still couldn't Bind to the receiver with the updated Firmware. I was working on another project last night using a breadboard, I connected the updated RXSR receiver to the DC rail to see if I could Bind the RXSR, it did so with no issue whatsoever. The RXSR servo signal output is strong and clean. I have no idea why the RXSR receiver will not Bind with the power from the ESC? I have repeated this experiment with three different ESC's producing the same result each time. Can it be as simple as Binding the RXSR using direct DC power to the receiver before moving it to the model? I really don't know hopefully this will help someone. Peace

Ordered 2, they arrived in no time. Great receivers for a quadcopter. SBUS, RSSI and Telemetry. Will buy a few more..

Attempting to bind this little guy to my older discontinued XD9 Plus I had issues. The red status LED would not flash on the R-XSR showing the binding process. I tried flashing the R-XSR several times and found that my issue was not the R-XSR it was my Radio. I needed to update the XJT internal firmware.This flashing the internal RF Module is right there on the main description of the item shown as the very first bullet point and I glossed over it. After I updated the XJT internal firmware it bound immediately to my radio.

This is honestly the smallest diversity and telemetry receiver I have ever seen. Not much bigger than a penny. Granted this is not for long range, but in areas quiet in RF I get fantastic range and penetration, with reliable RSSI readings. The binding process took about 10 seconds and has never needed rebinding. I use this receiver on all my quads because of its price, weight, and reliability.

This is my go to reciever. 16 channel sbus and smartport in a superlight supersmall cheap package!?!?!?!?! I have a xm+ that has been in every model i own since it gets used for a few days until i miss my telemetry then it gets replaced with this guy. It has pads for uninverted, inverted smartport and rssi making it compatible with all the flight controllers. Out of the box it transmits rssi and input voltage telemetry without a flight controller. if used without a flight controller in a plane or rc-car you can get smartport compatible lipo and temp sensors seperatly but to be honest getting a f3 flight controller for a drone and using it as a sensor board/data logger only is cheaper then getting just one standalone smartport compatible sensor.They can also be hooked up to a second reciever like a xm+ as a backup via sbus in/out incase it breaks or the antennas get ripped out. All i need is a simple sbus to pwm converter to drive servos. A big feature is the fact that you can plug it in instead of direct solder. it makes it easy to take the model apart since its usally mounted to the frame.The only downside is the voltage input. be aware that the input takes up to 10volts but since the on board regulator is linear and not switiching it will get hot when used over 5 volts and the ipex antennas suck when they come off.

love these super tiny receivers!! full telemetry unlike the xm+ which by the way is a tiny bit larger than this R-XSR.Installed on my micro and did a range test you can see the video on a popular video hosting site "u" tube.Look up channel "yattiyada." basically filmed my quad going down a trail until it lost signal at around .43 miles.I think it could have gone a bit further due to there was few tree in line of sight.I purchased 3 right of the bat and replaced all my xm+ and original xsr receivers. Lua script works great too.with telemetry i can keep my eye on RSSI, Vbat, and modify expo, rate, etc.I love these little guys!!
