FRSKY R-XSR | the new best FrSky telemetry receiver 

Already back-ordered, but very much looking forward to this receiver! Thanks for making this you always seem to be perfectly in sync with my newbish-ness needs! Between you and JC (respect) your willingness and thoroughness of sharing your knowledge is amazingly helpful and beneficial for the hobby! Many thanks!!!

Thanks again Joshua! Two months ago when I started with FPV I barley knew what that acronym meant. Now, very much thanks to you and your knowledge, I know that acronym as well as what SBUS means, what kind of dinosaur a Taranis is and can solder needed repairs to my drones! I and many others are truly thankful for your time, knowledge and mentorship.

Man, your videos are so simple and informative! Thank you!!!

Thanks for explaining the 'R' (redundancy) feature! Good stuff! ...and keep posting the good stuff, too!

berfore i clicked on the vid, i said to myself, "Im gonna learn something today"

Im excited about this and its great the xsr's are so cheap now

I went back on your channel to Aug 2014 flying a 450 and made me feel better about myself.

Jumping Jehoshaphat! I saw this video and had to have one. Happy to report: I am not disappointed! I had trouble trying to bind it with the TX. As I was pushing the little button with my thumbnail, the antennas kept popping off. Hot glue solved that issue. It is now in my quad, just forward of the PDB. Nested between the ESC power cables. Antenna wires are shrink wrapped to two small zip ties for stability, then, those are zip tied to the top deck/standoff at the front of the craft at as close to 90* angle as I could. Thanks brother! Keep up the awesome videos. I like how you throw in some humor and science to back up what you're saying.

You’re videos are beyond helpful man 👌🏽👌🏽💯

I've been using Frsky since 2011/2012, bought the DHT-u telemetry module for my 72mhz Futaba 9z. Was a diehard Futaba Fasst guy before but knew they were in trouble with Frsky. Definitely, an RC gamechanger. I was one of the first in line to buy a Taranis, still an excellent radio especially with the new hall effect gimbals!!. This receiver is absolutely amazing! Its shockingly small, little larger than my thumbnail. My range is just as good if not better than other FrSky receivers. Have done the "RSSI foxhunt" after crashing in the woods, I still kept signal in spots that my previous FrSky recievers would not. Frsky went through a lot of hardware changes, but its been worth it.

Great info, my next build will have one of these migrating from the x4r-sb

Very informative as always!!!

Love this and one of the main reasons we bought Graupner but have since gave up on Graupner as the rec/controllers are to big to put in our quads... the R-XSR is the way to go especially with the 20 x 20 stacks!

Just bought this receiver and saw the redundant setup in the manual, you answered my question, would need another tx module in my radio. A good idea if I build something big!

Josh, I'm an avid follower of your channel and I am always learning new things with each and every thing you post. I know this would be much more appropriate for one of your Q&A sessions, but I've been scrambling the internet trying to find a quick suggestion/solution. Anyways I've been building/tinkering/frying/ quads and components for a few months now and recently compiled a few new components together so I can get up in the air again. I'm on a relatively tight (or non existent) budget at the moment, so I try and make the best out of what I have. I'm running an Omnibus f4 with 3.2, Spektrum sat Rx, and kingkong 2300kv motots, and just installed 4x dys DS20A ESC's. When I plug in my battery (w/ smoke stopper of course) They all power on, but the beeping indicators are way out of sync of one another. I tried using BLHeli configurator to update and calibrate, but only 2 of the escs will show up, or sometimes 3, or sometimes none. It doesn't make sense to me. I can calibrate them by using the motor tab in Betaflight, and my quad will fly in the air, not gracefully, but I'm not having cataclysmic failures (yet). I just want to know why some of my esc's won't show up on BLHELI, because I want to update the firmware. My first guess would be in the signal wires between ESC and FC? I've checked them for soldering errors, and all seem okay. I dont have any of the ESCS running a ground wire to the FC. I also soldered the signal wires directly to the FC using through-hole style for cleanliness. If you could toss me any suggestions or explanations as to why my ESCS won't calibrate collectively or why only some of them show up in BLHeli config, I'd be very appreciative. -Also, I know a bunch of you all that watch these videos are far more knowledgeable than myself and I would also appreciate if any feedback you all could provide. Thanks in advance.

Looks good! Nice that they added redundancy but I agree with you that for mini quads, probably not a huge deal.

Joshua, thanks for all the amazing knowledge you share with us! It makes it so much easier to be in this hobby. It would be incredibly helpful if you explained some of the differences and different application of the various micro Rx models made by Frsky. Every time I go to buy a new Rx I am faced with trying to decide which one is best for my application. It would be great if youmsaid "don't waste your money on this" or "this is the only one you need to think about". I'm certainly not lazy about research but your experience and knowledge would be greatly appreciated and give many a lot of confidence when making purchases. Thanks again, keep up the great work !

While it's certainly possible to use it with 2 transmitter modules, I doubt that that was their intention. I think it was more intended for binding 2 chained receivers to a single transmitter module. Then you can have 2 receivers listening, have good antenna polarisation in all 3 dimensions, and in the case of models with many RF shadow areas (e.g. carbon sailplanes) also have antennas in more visible places. What I do wonder about though what is the strategy for chaining multiple receivers together where 2 or more support telemetry: From what I can find in the manuals, I don't see any means to disable telemetry in telemetry-receivers. This is important because it doesn't make sense to transmit telemetry from more than 1 of them at the same time. What I really wish FrSky would do is make their receivers programmable using PC/smartphone apps as is done by EzUHF, DTF-UHF, etc. so that users can define which features they wish to enable/disable and which channels (or RSSI) is output on which ports. That'll be a winning move on their behalf IMHO.

Great to see a small one with telemetry. @Joshua I love your videos and almost watched all of them. Some are now outdated (old BF versions) but nonetheless very instructive. After the build video I would love to see what are things you do on the software side, there are so many new features and advices are spread across multiple videos it's hard to keep track. What are all the things you do when you configure a new quad from scratch? Including ESC, BF configuration (quite a big topic), useful LUA scripts and last but not least symptoms and solution pointers to most common software issues. Keep up the good work!

Interesting to hear you like adjusting PIDs better with the Taranis than with the OSD. I have not used BF OSD yet, but with MWOSD I definitely understand - it is a pain to navigate through it. About time to implement MSP on my OSD FW to change this.

Hi @Joshua Bardwell. I would like your expert input on this issue: I am using a TX12 EdgeTX and Jumper R1, Frsky XM+ and Jumper R8 receivers connected to SBUS decoder. When power is applied to the receiver, they move servos connected to most channels from dead center to -100 or +100 than back to center. That does not happen to the R8. I tried to configure the failsafe on every mode available but there is no change. Is it a normal behavior for these tiny receivers? Because I need it to keep steady dead center/neutral on all channels when they are powered on.

Thanks for tip it got my mind working for solution

Having a nightmare wiring an RSXR up to my Darkmax, I've been trying inverted and un-inverted SBUS signals from RSXR to PPM/SBUS(RX6) on the FC but can get no response showing in Betaflight (10.4.0 osx) 'receiver' tab. The previous receiver was an XM and worked fine (after switching ports to RX6). The Darkmax has an Artower F4 FC with latest OmnibusF4sd firmware (fw). The RSXR - fw 171009 (lbt) binds fine to Taranis X9d - fw 2.2.2 (lbt). I understand that s'port from the RSXR can connect to RX3 on the FC for telemetry, and I can also combine this with the s'port from the GPS sensor I haven't got to yet. The Artower F4 also has a plug for DSM(RX1) which I don't know what to do with.

Great video Sir ! This R-XSR RX would be great in my DLG , can you advise me how to connect 4 servos to it ? Thanks.

I have one of these going in my next build - about 2 weeks ago I bought 2 XSRs @$15 (hard to pass that up), and an R-XSR to evaluate. If I had known about the Sbus inputs, all 3 would have been Rs. (wondered what the "R" stood for) (*#1) I fly giant scale fixed wing (neglected as of late due to quad fever) and all those are equipped with redundant setups, using a X8R and a XM+ in the far wing, both on independent batteries (total of 4 receiver inputs). Thanks for the tip on using the Module to backup the TX as well, I may implement that on my giant scale as well. It never occurred to me.(*#2) I've been looking for a way of using a backup Tx since I bought my Horus last spring. Now for 20 bucks and a few grams, I can use either my Horus or Taranis with my main quad. I'm not a hotshot pilot or racing (yet) so the 12grams or so won't matter. I really did learn something today, (2 major items actually*) and it's often your videos where I don't expect much new that are full of great stuff. Thanks Joshua, for doing our homework for us. I'm one of the weirdos who like antennas soldered, for the security reason, I find the Ipex work well if you assemble everything to get the orientation adjusted, then add a tiny dab of the Chinese low viscosity white RTV (flowable - Kafuter brand - best deal at a HK hobbyking.com/en_us/k703-silicone-glue.html?___store=en_us). It holds securely, but is easily removed by nicking with a #11 Xacto and lifting with a small screwdiver. Best of both systems. You can re-heatshrink over the connectors if orientation permits for even more protection. PS, I also have 3 el cheapo micro receivers from BG that were 6 bucks a copy. They're like a non-diversity XM+, but those are intended for whoop or indoor builds, as I wouldn't trust the control of a 1200w spinning blade of death machine to the cheapest Banggood has. (same reason my GS planes have redundant diversity and Rx power systems), they will all leave a mark. They seem to be the one used in a some production FrSky flavor Tiny Whoops and are a good add-on if you're a BG customer. They are smaller than an XM+ (barely larger than the SMD chip). Scott

After reading all the "redundancy" in the questions below, it would be nice to make a comparison between all these frsky Rx, especially as far as antenna length goes. So we will learn something that day😉thanks.

Thanks you for all your Vids ! Could you continue to put subtitles ? I'm in France, and look at your videos with the subbtitles helps me a lot !! Thank's a lot Mr KnowItAll !! ;)

Do you have a recommendation for a good installation video? I have a mamba f4 stack with a rush tank vtx and I can bind no problem but cannot get my stick inputs to respond in betaflight. This is my first build and its killing me I cant get it in the air...thanks!!!

Having trouble binding this rxsr... when i power on holding the failsafe button red light never starts flashing... ive tried flashing firmwares access and acct.. my question is can i bind using fport in betaflight?

Does the betafpv literadio 2 frsky d8 bind to xm+ or x9m or will it work to fly the baby croc analog?

Love the videos like always, but it would have been most helpful for me for something a little more practical - explaining the pinouts Smartport, Sbus_OUT/CPPM and SBUS_IN for wiring up properly. I'm sure that it's basic, but something a little more practical would help!

great video. thank you sir.

joshua Bardwell i stripped down one of my quads and found the heat shrink melted on my rxsr and the little top bite of the bind buttons missing its still bound josh but if i need to bind it again can i bridge across the switch with i bite wire or a fine screwdriver to get it in to bind mode plus i never updated the rxsr and always had low rssi problems i really should try and get it updated to fix the rssi problem lol this quads has problems falling out the sky must be failsafing i think

I guess the new r-xsr boards have little pads you can solder to get the (un)inverted sbus and smart port signals from. The smart port pad has a P next to it and the sbus has a B next to it. This was an update to the receiver as 13 October 2017 according to OscarLiang.com

Joshua.. I have a question. I kind the R=XSR with a power supply and get a solid green light showing bind. I hook it up to the flight controller and get rotating light flashing Blue, red and then green ... The only thing I find in the manual may be it's not set up right with the controller...but when I set up the flight controller to either cppm or sbus... It doesn't change. Lights still flash in rotation.. Any ideas? I've changed the cable so the sbus/cppm output is on the 4th pin instead of the third s port. THanks

Hey Joshua! I've got a question, and would love to know if you have an answer to it: So, about 3 months ago, i crashed my quad fullspeed topdown intro a concrete block, i think one of my motors was bad which made it turn off for a split second mid punch, when it turned back on, i was too late and made a hard smack - things i broke when it happened The damage was honestly not too bad, my VTX antenna had been ripped off the print so that burnt out. Also all 4 motors had died. After ordering these parts and rebuilding it all, it flew amazing, total cost was about 70$. (Its a 3S toothpick, Eachine Novice III to be exact) When i took it back out for its first flight, i noticed the RSSI was really low and it fell out of the sky about 10 meters away from me, i noticed one of the antenna's was cut off, i bought a set of new ones, put them on but it made no difference (its a ESC / Receiver combo) so no external receiver i checked all my settings in BF, rebound to my transmitter but no luck, do you think i killed the esc / receiver combo or a different issue? Here's a link to the esc / receiver: www.banggood.com/Eachine-AIO-F4-Flight-Controller-12A-2-4S-ESC-Frsky-Receiver-Part-for-Novice-III-Viswhoop-FPV-Racing-Drone-p-1649353.html?cur_warehouse=CN&rmmds=search If it would be this part, could i add a external micro receiver to it? Also, its not my transmitter, as my tinywhoop works fine with it and has good range Thanks in advance.

Thanks Joshua ... I'll be haunting the BangGood site, sigh. Regarding that plastic socket - any idea what fits it or would it be easy to remove and solder to the board?

Just got mine and installed it with redundancy with an XM+. I just exchanged the antennas with 1/4 wave ones. did a range test today (see my channel) and the only thing that stopped me was the video signal. No low signal alerts, everything good. I went 0.99 miles away (1589m) and everything OK ;)

Think theyll make a v2 like the r9mm with pin holes. I mean the commector is twice the thickness of the pcb. I've depined them and the reciever goes anywhere. Jw thoughts?

How do I bind this to the jumper T light controller I either missed something or I'm not doing it right because I cannot get it to bind to my controller

I bought a Cicada AIO Flight Controller (F4, 30x4 BLHeli_S DSHOT ESC, OSD, PDB w/BEC, Current Sensor), RunCam Sparrow and a Frsky R-XSR, so I got 2 questions 1st for the R-XSR where do I solder the sbus out/cppm to in the Cicada AIO FC ,because I want telemetry or just what to solder to have the X9D give me an audio telemetry. And my 2nd question is where do I solder the audio from the RunCam Sparrow to the Cicada?, can you help me?, thanks and keep up the good work!

will this bind to a jumper T8sgv2 plus without flashing stuff ? , as the quad I like has one in it, I don't care about telemetry.

'm using that receiver but can't get any input to wrk in betaflight, I've wired it properly it binds but no input, could it be just a bad one u think? I'm using the dalrc f405 fc I have sbus going to the rc tab which is uart 1 so I'm not sure what else to Do, any ideas

does it have a longer range with telemetry off? using x9 lite S

Where to connect the sbus out

Just got my crossfire jr module today but this looks cool

nice info soon ill be trying that frsky lol still flyskying it here. Teach you ever play with overclocking on the f4 boards to drop cpu load when running 32k gyro ? would this give kwad better performance overall like overclocking cpus for gaming ? also you think air flow is enough for cooling or you think a heatsink should be added?

You forgot one... The xsr-e. Excellent for micro builds as it stacks at 15x15mm.

How can you tell if a transmitter has it? 8sg+ or t16s or a jumper

Joshua: Have you ever had issues with Low RSSI after changing out an Ipex antenna on the X4r-sb receivers? i have three now where I have changed out the antennas and I get low rssi warning when about 15 ~ 20 metres away.

ok so how do i get telemetry? i have 5v to 5v on DYS f4 mini fc and ground to ground and sbus out to sbus... do i use the yellow wire on the harness/connector and take it to a TX (open UART? like UART 6)? or do i have to take the a wire and solder it from the s.port uninverted pad to the TX (open UART? like UART 6) i cannot figure it out? or do i just get telemetry by using the sbus wire alone? please help me out! im puzzled

Hi. There is an External RF mode called “SBUS” in Taranis. Do you know what it is for? Thanks!

hello can i get drone battery level on my transmitter? i am using this receiver and tx 12 transmitter.

What frequency does the telemetry go back to the TX on?

After the about a month or so of playing with the R-XSR, I can definitively say the range isn't what it should be. At best, I get 200-300 meters before my range warning goes off. I've tested this on two seperate copters both with new R-XSR's in an open field with no obstructions. (EU firmware with EU Taranis) When i get the chance, i'll swap back to using the XM receiver as at least I'd get 500 + meters before experiencing a noticeable reduction in signal strength.

Is it a good idea to buy this today? I'm running the XM+ but now i would like to experiment with GPS and receiving coordinates on the Taranis

Man I switch to the qx7 just to start using the rxsr. I have osd and still am finding I get into the flight a bit too much and don't stop paying attention to my osd voltage read out then bam! drops like a hammer due to deader than dead lipo. I decided I need telem on my radio and set it to vibrate on critical battery.

Sounds like the "redundancy" feature could be a great way to buddy box... Just a thought.

Bob (KababFPV) should release small transmitter with modules, would be great to have smaller TX too. If he will manage to do it with OpenTx that would be easy buy.

I have never setup any rssi on my quad because i dont know how to do it. Do i have to solder something else on to the r-xsr just to make rssi to work or is it within the s-port telemetry cable?

Do you think there would be an option to make a tbs crossfire the slave Rx and hop between 2.4 GHz/900mhz?

I wonder if they will ever build an R-XSR with an XM+ built in as a single unit with redundancy

Check out the furious fpv receivers. They have a d8 version and a d16 version both with diversity and telemetry.

By mistake I cut the antenna wire of my xm+ but the replacement I have is longer. Can I use a 10cm and a 15cm antenna in the same receiver without affecting range?

I have a question.. I have a Taranis QX7, if I buy a larva x with R-XSR already installed will I be able to remotely bind it to my QX7? Or will i need a cable to connect the R-XSR receiver to my radio physically for them to bind? Any help would be great! Thanks Josh!

I asked them to make this receiver with 1/4 antennas when I chatting to them in China. Do you know if it has it? It's one of the reasons I've stuck with the X4R. It's the only one i trust for the longer range flights.

I get no rssi on my qx7 with the rsxr, I tried binding with my qx7 on both D16 1-8 telemetry on and 9-16 Telemetry on and neither gives me rssi in the qx7. Any ideas? Thank you for excellent vids.

Can the r-xsr receiver be easily installed on a Eachine Trashcan PNP-version? I have read that the FrSky SPI receiver D16 mode is not working with RSSI/telemetry but the r-xsr receiver would?

How are the antennas ? 1/4 or 1/5 wavelenght ? What i don't like about xsr is that it comes in 1/5 wavelenght and test have prooven that it DOES AFFECT RANGE. i have like 10 spare antennas for new micro ipex from banggod anyways so no biggie, but good to know :D

Josh! I have the international version frsky taranis x9d plus the same as yours ( i knew i have the international because i have d8, d12 , lr12) . Flashed the xmplus with every possible version and it wont bind . Please help

My new catalyst machine works merica drone came with this receiver. Can I use my tango transmitter with a Frsky xjt tx module? Sorry still learning about this part of racing drones!

HI, I'm building my first quad and I see on a quad forum they mention that the R-XSR needs to be (un)inverted to work with the Hobby Xrotor 40amp F4 FC. Please tell me that's not the case. I don't even know what inverting means. Thanks

Is it compatible with the F4 Bardwell v2??

does anyone know where is the un-inverted telemetry pin on R-XSR?

Anyone know where the uninverted S.Port signal is located on the R-XSR for those of us flying F4 FCs? Could be a deal breaker.

Hi Joshua. I have one of the new XSR-M receivers. Do you know if it is possible to mod this receiver to output an uninverted telemetry signal so it will work with my F4 Flame FC. On the X4R-SB it was just a matter of soldering a wire to a pin of one of the chips. Thanks for teaching me 99% of what I have learned about quads.

I have an XM+ receiver whose antennas got chopped by props. Since it is ipex connector, I went and ordered spare antennas with ipex connectors but the connectors appeared to be bigger than those on XM+. So are there two different sizes of the ipex connector?

The biggest thing I like about telemetry is it lets me know if I have damaged receiver antenna. Sometimes I just can't see the fault in the antenna. Saved my ass a few times.

Hi, Joshua Bardwell! A question on the transmitter. R-XSR. I sabinder RSSI is working, the green indicator works, here's the problem I can't Betaflight not see the instrument controller. What could be the problem. I flashed 2.2.1 equipment the equipment Taranis X7. Maybe that hardware to configure. The old transmitter all right run and everything else he sees.

Joshua bardwell could you do a review and range test on 1/5th wave and 1/4 antennas and if we should be modding our frsky antennas to 1/4 wave

One you didn't mention is the XSR-E. It's an XSR in 15x15mm form factor. It's my top pic until the r-xsr comes out and I can try it.

do you know where to pull the uninverted s.port from for connecting telemetry to an F4?

Is it possible to bind one reciever to two transmiters.. all frsky ? Really want a new one but would also like to use the old on occasion. Thanks !

Can you get rssi with the r-xsr receiver?

Well I was so exited I bought 2. Built a floss with dys F4/30a 4in1. Telemetry output is giving weird figures. No vfas either. Using BF 2.2 and I tried setting inversion both ways. No lua script either. Have any ideas?

Josh I picked up a Taranis QX7 I don't know if you've used one but hopefully the opentx is the same. I'm having problem creating switches. When I do I am not getting the full range for mapping within betaflight. The switches mapping only at 1500 2000 so 3way switches I can only use as 2 and something different for my arm switch which is a 2way acknowledges the initial movement but sticks on arm in betaflight. This happening on 3 different FCs as well so not isolated to that? Any ideas I've search and posted several times and have had no luck. Just got thru my first builds too and never thought this would get me. The receivers I'm using is this one your reviewing and the XM+

After your video's i need to mod my turnigy 9x to get frsky telemetry :)

I am replacing my xsr receiver with an rxsr. The wiring looks the same with the same connector, however after i bind the r-xsr the quad just beeps constantly. When i unplug the quad the taranis says telemetry lost. Why would plugging in the rxsr over the xsr cause the quad to beep constantly?

I fixed it, I installed zafdig to fix driver since it wouldn't boot and then flashed 3.1.7 and it's fixed now,crazy scenario though but had to be ok firmware interfering with new version gu maybe

Could you just bind both to the same model and have it work kind of like Spektrum Satellite?

A bit off topic but thought I'd ask. Have you had a chance to try the LaForge 3.0 firmware? It's been released and it's pretty freaking awesome!

Sbuu_in to do redundancy, interesting. Does that mean you could technically have say a Futaba sbus receiver connect to the rxssr and even have dual brand redundancy?

Hi how are you congratulations for your Chanel . I have a fly sky FS-T6 and I can’t to connect with mamba f722s you can help me?

Can you run use this rx for PIDs on a quad using smart audio for the TBS Unify?

What is r-xsr compatibility with f4 flight controllers? Is there a hack available?

How do you wire this R-XSR receiver to a cl_racing F4S FC so I you get telemetry to a FrSky Taranis Q X7s? I'm stumped!

Hello guys Has anyone added a buzzer to builds using this receiver?

A bit off topic but can anyone help? I'm having trouble getting my motors apart because of the c clip, I can eventually get them off but I end up damaging them in the process. can anyone recommend a tool that is made for the job as I cannot find one

I just have a quick question that I can not find the answer to anywhere ...dose the xsr have the same range as the r-xsr ??

Thanks posting this Josh! Now I know why the XSR is so cheap on Amazon. "...And knowing is half the battle..."
