FRSKY R-XSR | the new best FrSky telemetry receiver

Until now, if you wanted a FrSky receiver with telemetry, you had to spend about $25 on an XSR or an X4R-SB. FrSky has just released the R-XSR. It's $20. It's tiny. It supports SmartPort telemetry. And it's got redundant capability. If you want a FrSky telemetry receiver, the R-XSR seems like the new go-to. On top of that, the XSR is now marked down to about $15 everywhere I looked!

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.

[@ultan04]

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

[@barthchris1]

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.

[@BOTGRINDER]

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

[@marinehm]

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.

[@DanielStinebaugh]

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!!!

[@sailorjohn2224]

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

[@hobbyzonemodelismo]

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.

[@JuicesJuicyJuiceShack]

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.

[@cubitusclaudius]

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 ;)

[@kellypowers849]

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 !

[@JoshuaBardwell]

R-XSR (telemetry) or xm+ (no telemetry) are pretty much all I use.

[@kellypowers849]

Joshua Bardwell thanks! That certainly narrows it down!

[@4DCResinSmoker]

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.

[@AbdullahAdnanID]

Me too. I got rxloss on 185meters away.

[@nicolasazar96]

@@AbdullahAdnanID also on EU firmware?

[@scottmarshall6766]

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

[@JoshuaBardwell]

Those micro SBUS receivers are usually D8 protocol, which means they don't do SmartPort telemetry and they don't allow Failsafe configuration from the radio. Those are deal-breakers for me in most every case. Glad you learn something from the videos.

[@scottmarshall6766]

I've got a lot of stuff on the shelf that didn't make the cut. Seems to be the nature of this game. Unless you can afford to buy the best of everything, and sometime even that isn't enough. Occasionally parts just don't work out or aren't what you thought/expected. So you put them up and hope someday you or a friend wiIl use them. I don't think anybody makes a d16 telemetry whoop size Rx though. (but I'm frequently wrong on such things) I don't use anything I don't trust or doesn't make me happy. I watched you do it not long ago in the Lemon build (Camera). It happens to us all. That is one of the major reasons I support you, you do a lot of good for people, and the few bucks of patreon I spend are more than offset by what I learn and the money I save not buying junk or incorrect parts. It's good for the hobby there is few of you who are able to make a living in it and are the voice of the little guy to the industry. We have a unique mix of people all working together in this thing that no other discipline enjoys. It's our strength, the extreme diversity in it's community. No matter your problem, there's somebody out there sharing it and somebody who knows the solution. I just can't afford to spend the time you do checking out all the parts available, but somehow you seem to keep up and have covered most parts I am looking at before I buy. The information you provide is a 'force multiplier' for the community. We can spend more of our free time building & flying, not researching and reading Chinese translations trying to figure out how to hook something up. I usually get in trouble at 3am when I go on to order the odd part, and next thing you know I've got a couple hundred bucks worth of 'stuff' enroute. Paypal credit can be hazardous at 3am. Then you wake up in the morning with a 'parts hangover'.... and a bill... I think that's how I came by the elcheepo receivers... Thanks! Scott

[@ChristKrew-Rev1.8]

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!

[@FinalGlideAus]

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.

[@JoshuaBardwell]

I don't know which antenna it has. I hope it's the 1/4 wave. Going to 1/5 wave is completely inscrutable.

[@mlentsch]

"inscrutable"... there's a thesaurus word if I've ever seen one!

[@rolandburrows4859]

Inscrutable? Does that mean don't buy it?

[@easttnscott7629]

Can you compare the antenna length on the r-xsr to a X4R that you have?

[@lajulasse4332]

I was going to ask just that, range? Wait and see then.

[@ZSHREDPJ]

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!

[@haustiersteinfpv9181]

Hold the button while powering up initiates the bind mode. No cables needed. I have the larva x and I love it but I definetly wouldn't recommend it to a beginner because it's not robust.

[@ZSHREDPJ]

Haustier Stein thanks a lot bro!

[@WinstonSmith1984]

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.

[@rl2109]

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

[@theibault]

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

[@PilotPlater]

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!

[@Trolleydolly130]

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.

[@Kevin-Kx]

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.

[@Edward-Norton]

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

[@davidberry8463]

[@AelDiaoul]

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!

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.

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

[@rogeliomartinez7847]

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

[@nevinleiby]

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!

[@davidlondon3111]

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?

[@airwolffpv7984]

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.

[@jeff57]

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.

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!

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?

[@JoshuaBardwell]

+youel adamas overclocking isn't needed unless you are trying to run 32 kHz.

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.

[@wdavie27]

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

[@aliens99xx74]

'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

[@BongToker]

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

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.

[@JoshuaBardwell]

I would guess either the antennas are not the right connector or the IPEX connector on the receiver is damaged.

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.

And it's only $18. But as far as I know doesn't support the redundancy feature.

DroneRacer101: But does support telemetry correct? If so do you know where to pic up the in-inverted signal?

[@SimRacer101]

Ol-Man-Duffy J It does. Exactly the same as the XSR, but it comes with a short cable with a 4 pin jst-sh on both end so it is SUPER easy to wire. I used it on the GT200N video I did. Just had to move the smart port wire to another jst-sh connector in another uart. It's an F3 board so I didn't have to worry about inversion.

[@ol-man-duffyj688]

DroneRacer101: sweet! Thanks for your help man!

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.

[@JoshuaBardwell]

Yes, definitely but the question is where to solder the wire. And for that, I don't know the answer.

[@tbrown1352002]

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!!!

[@AndrewBlanche]

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+

[@JoshuaBardwell]

I'm not sure what is going wrong but surely it's in the Mixer of the Taranis. When you create a new mix for the switch, has it got weight of 100 and offset of 0?

[@AndrewBlanche]

Joshua Bardwell yes I've followed a KZbin video on how to do it sadly the gentleman who made video passed in an accident I here, could it be a firmware update problem cause I also have an error accessing the SD card tried several so know that's not the card. I had forgotten about that and just put a card back in today. Are you supposed to change Diff to Expo or Function cause that's really only thing I've haven't tried. The video on KZbin I'm talking about is the guy Blue Falcon Experience. Maybe he was wrong I don't know. First you setup in inputs correct? Chose the switch for that input than in mixer you select positions of the switches correct?

[@AndrewBlanche]

I think I found issue watched some old videos from you and Stuart I don't need got into inputs, and the switch range I think the output ranges are all 1500 2000 not 1000 2000, I will go check that in morning.

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.

Where to connect the sbus out

[@madyet5235]

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

[@JoshuaBardwell]

RXSR yellow wire (smartport) to the UART TX pad on any F3 or F7 flight controller. F4 flight controller needs an inverted UART TX pad, which will typically be labeled as SmartPort or T(elemetry). If you have an F4 flight controller with no telemetry pad, here is the approach that will work: kzbin.info/www/bejne/oIWXp5lsapxoiq8

[@daniel32768]

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

I don't know yet but you can manually fix the 1/5 wave antennas if you want to.

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?

[@vtowndegekste]

I got a rssi pad on my Xrotor hobbywing f4 g2 FC , do i have to wire something on to that pad or just on a rx of tx pad?

[@JoshuaBardwell]

Please search "Joshua Bardwell rssi in osd" to find my video about it.

[@QSpeedRacer]

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

[@OriginalGingaNinja]

Hi Joshua, Quick affiliate link question. I'm going to order one of these, clicked the link in the description for BG, not in stock yet, clicked alert me on arrival. For you to get the credit do I have to come back to this link when's its in stock, or will it register to you now anyway? (Seems unfair if you lose the credit because it wasn't in stock at the time)

[@RogerBurgess]

OriginalGingaNinja you will need to come back and use this link in order for Joshua to benefit (what a nice chap you are for asking). P.S. Do not rely on receiving the alert as I find that roughly only 1 in 5 alerts I setup come through from BG. Just bookmark the page and revisit until it's available. All the best, Roger

[@OriginalGingaNinja]

Roger Burgess Thanks mate, I learn a lot from Joshua, if I'm going to buy it anyway seems fair that he gets the benefit of introducing it to me. ☺️

Typically, the way affiliate links work is, when you click it, you set a cookie. The cookie might last for as little as 24 hours or as long as maybe 2 weeks typically. It could be longer, but it seldom is. Any purchase you make while the cookie is present on your browser, the affiliate gets credit for. If you click a different affiliate link, the new cookie usually replaces the old one. So the safest thing to do is to click on one of my affiliate links immediately before you add the items to your cart and purchase.

[@GabrielLarke]

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!

[@JoshuaBardwell]

Yes and it is awesome.

[@ATrustInThrust]

I totally know what you mean with the 20$ and 25$ thing, I think it's cause we've all been taught to round up if the digit is a five, so 25$ somehow registers as similar value to 30$ even though it's not even close. Just speculating.

[@RectifiedMetals]

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?

[@JoshuaBardwell]

Lua script doesn't work unless you update the firmware. Telemetry problem may be because inversion is not working. You can't fix inversion via the CLI. You can only tell the FC whether it should expect to see an inverted telemetry signal. If you bought a new R-XSR, there is an uninverted smartport pad. Use that, and set telemetry inversion to off. Then you should be able to use any UART RX pad.

[@RectifiedMetals]

Joshua Bardwell thanks pal. Yep I have one. I found Oscar Liang's blog giving that a try now. Wish me luck!

[@RectifiedMetals]

Joshua Bardwell update. Updated the firmware, soldered to the pad, zip. Fooling around I lost the pad, tried tracing and found 2 legs on 2 chips that had continuity. After fighting to get to the legs, zip. Decided to reverse and use uart1 for telemetry, and uninverted sbus on uart 2, nada! Where to now? Have you had hands on success with the r-xsr on an F4 other than the holybro? Damn I wanted the LUA.

[@holc123]

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

[@racem558]

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.

[@christopherbigelow1323]

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

[@Waikhom007]

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

[@FabioKastro]

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

[@JoshuaBardwell]

It's still a solid receiver if you're using FrSky.

[@Grandpa_mangakit]

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.

[@2strokeme64]

Фрос move signal wire to pin 4 instead of pin 3(yellow wire)

[@Grandpa_mangakit]

thank you. I'm all hooked up

[@icecorebaby]

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!

[@JoshuaBardwell]

Yes XJT will work with RXSR

[@icecorebaby]

Joshua Bardwell thanks! Going to order that module now!

[@kenspaceman3938]

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?

[@JoshuaBardwell]

Betaflight 4.0.6 claims to have fixed the SPI receiver lockup issues. I haven't verified that though. It shouldn't be too hard to install the RXSR on a Trashcan though.

[@kenspaceman3938]

Would it be good then to buy the bnf version of trashcan with the integrated Frsky SPI D16 mode receiver, try it out with that new Betaflight firmware, and if it doesn’t work with rssi, somehow bypass the SPI receiver and install a external x-xsr receiver? Is this possible? Hard or easy to do? I can manage basic through hole soldering. Thanks for your kind advice!

[@daythis2825]

Hello Joshua! I think there are some mistakes in your R-Xsr introduction... The redundancy mode is a Master/Slave mode so you only can bind one receiver (slave one) and the R-XSR will manage which receiver will works. By this way you can't have a separated Tx and you don't need an external module. What I say is only valid if they didn't changed the operating mode of redundancy.

[@JoshuaBardwell]

I took my info from the R-XSR manual, which seems to instruct binding two receivers (such as an R-XSR and an XM+). The R-XSR will manage which signal is inbound yes. But I don't see why you couldn't bind a different Taranis to the XM+ than the R-XSR, or use an external module instead of binding the same radio or module to both.

[@daythis2825]

Ooh it changed then. I thought you could only bind one Taranis with two the deal changes yes. I wait for it, I hope it's fully functional! You're Joshua Bardwell and today I learned something, keep going :D

[@GoatZilla]

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

[@TransAm2k4]

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

[@rc-hr8oi]

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?

[@JoshuaBardwell]

Yes unfortunately so. You need the "new/small" one. I am pretty sure this is the one you want: goo.gl/hp3h8G You can also try this one: goo.gl/GsthN1

[@nandakoryaaa]

Thank you very much!

[@MrTophe75]

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

[@momentum3825]

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

[@JoshuaBardwell]

XM+ should bind in D16 mode. If you have the international version of the radio, then I htink you need the FCC firmware right? Because the LBT firmware doesn't include some of those modes.

[@momentum3825]

Joshua Bardwell sorry for bothering bud, but i did flash it with fcc but still nothing. The flashing is successful but itwont bind

[@AustinChopra]

One comparison you could make for the ipex connector on a vtx is "it's like trying to put a V8 engine in a smart car"

[@sulan91]

You can actually control 2x recivers from your taranis with just the internal tx. I flew 3x of my quads at the same time last summer, hovered, did a flip and landed :)

[@OriginalGingaNinja]

sulan91 I'm interested, do you just set up each receiver as a different model but give them the same receiver number?

[@JoshuaBardwell]

Yes, you can do that. This is something I thought was too much detail to lay out in the video. You can use an XM+ and an R-XSR to do a satellite receiver setup with a single transmitter.

[@sulan91]

None if that is necessary. Just use one model and bind the receivers. So if you have multiple quads you can fly them all at once, it's just really hard since they all hover att different throttle values ^^

[@wrecklesscreations5913]

Joshua Bardwell what about setting up a quad with a master and slave transmitter, for when I teach my dad to fly, so I can easily take over if something happens.

[@norgtube]

Ya. Binding isn't a 1-to-1 link, it just tells the receiver which Tx to listen to. So you bind them all to the same model, and off you go.

[@RobertoCamachoNoellySerrano]

Very informative as always!!!

[@digitalflyfpv6688]

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 ??

[@JoshuaBardwell]

Yes they are both full range receivers.

[@digitalflyfpv6688]

Joshua Bardwell your the man Bardwell thank you for the quick response!

[@icantflyfpv4835]

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?

[@JoshuaBardwell]

RXSR and XSR do not use the same pinout even though they use the same plug. You can't simply plug in an RXSR where the XSR was and expect it to work.

[@icantflyfpv4835]

thanks again. i moved the outside cable on the connector to the inside. moving the sbus to the sbus/cppm. and then i had to change the mode to sbus.

[@sladelefty]

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.

[@sladelefty]

well found the problem-the rxsr will not pick up tx signal if the tx is sitting too close to the rx. Rather strange.

[@JohnnytheBikeGuySLC]

I like a little dab of Lazerbond on my ipex and keeps em real secure... And all my solder joints...

[@mr.ramtech]

Correct me, but was not the FrSky XSR-M Receiver the new kid on the block? Very small form factor with telemetry

[@JoshuaBardwell]

The XSR-M is fine too, but it's 20x20mm whereas the R-XSR is 16x11mm so a bit smaller. For a micro build with a 20mm stack I would consider the XSR-M, but otherwise I would lean towards the R-XSR. Another advantage of the XSR-M though is that it outputs PPM, although these days nearly everything supports SBUS.

[@zaniix11]

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

[@JoshuaBardwell]

No, I don't.

[@cameronjacobs3144]

Yes i also need the answer to this

[@jeebs9439]

if you have the new version there is two pads under the authentication sticker, that provide uninverted sbus and uninverted telemetry, oscarliang.com/ctt/uploads/2017/10/frsky_r-xsr_rx_receiver_smartport_sbus_inverted_uninverted_pin.jpg

[@DangerDavefpv]

mr bardwell i have a odd issue, so i got a drone from a friend and it had a dtfu flight controller but i couldnt get the receiver to work in betaflight.. well i put my brand new betaflight f3 on and it had 3.0.1 firmware so i left it so i had everything setup and receiver worked with radio on blah blah but as soon as i disconnect and connect and connected lipo to start my motor test it wouldnt arm.. so i figured i was off on endpoints on radio maybe. nope it dont show no green lines or anything in receiver tab if i switch over from motors tab to receiver i see all the receiver channels for split sec and then nothing at all its all clear no colors for any channels. What the hell could this be? could i have bad esc causing short or something? got two flight controllers doing same thing and one is brand new. sorry hope you can follow my question

[@JoshuaBardwell]

Try reinstalling the configurator.

[@JoshuaBardwell]

Also if you are on 3.0.1 there may be backwards compatibility issues with the current configurator.

[@DangerDavefpv]

Joshua Bardwell thanks I just connect to whatever was on board ,Josh here is example what receiver in betafight looks like all 0 in receiver section www.rcgroups.com/forums/showthread.php?2871573-Betaflight-Receiver-Tab-shows-all-0

[@pedro_cataldi]

Is it compatible with the F4 Bardwell v2??

[@fitrillu]

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?

[@JoshuaBardwell]

+Drac FPV yes it's fine as long as the radiating element is the correct length.

[@RobB_VK6ES]

yes

[@multikillgaming2639]

What % wave length do the antennas receive? I recall a Steele vs Stingy video where they test two FrSky Tx, one with a larger % wave ratio than the other and the larger wave radio clearly beat the smaller wave ratio.

[@OriginalGingaNinja]

Although I thought the antenna mod to the antennas fixed that? Have I got the wrong?

[@JoshuaBardwell]

1/4 wave will beat 1/5 wave no question.

[@multikillgaming2639]

Joshua Bardwell So am I hoping for too much in assuming the R-XSR is 1/4? :)

[@multikillgaming2639]

So forgive me, but I'm still lost on if the X-SXR is 1/4 or 1/5 wavelength. Also is that completely dependent on the antenna length or is it also an aspect of other hardware tuned to detect the different wavelengths?

[@OriginalGingaNinja]

MultiKillGaming We don't know yet, however it's just down to the antennas, you don't even have to change them, just strip more if the outer case off it to the right length. I've done it on me XSR, measured them against an X4R only takes a couple of mins.

[@evanhunterblbier]

Having issues with mine on a CLRacing F4s, it binds but no receiver response in BF. I used the 3 wire harness on the R-XSR with the yellow coming from the s port on the receiver going to sbus (uart1) on the FC. Any ideas why the receiver isn’t responding? Channels maps are setup correctly. Thx

[@JoshuaBardwell]

Serial RX enabled on UART 1 in the Ports tab. Serial Recevier and SBUS configured in the Configuration tab.

[@gnr-bob183]

Sure you can hold button to change from ppm to sbus

[@2strokeme64]

Mine came with the signal wire in the wrong spot on the rx end of the plug, moved yellow wire over one spot to sbus now bf gets inputs.

[@Astino7]

Saw a post about the R-XSR not supporting LUA scripts, have you heard anything about that?

[@JoshuaBardwell]

+Alexi Philippou that is correct but they are working on a firmware to fix it.

[@Astino7]

Joshua Bardwell thank you !

[@waslater]

Josh, can you point us to a good tutorial for setting up the latest Lua scripts? I think you just sold me on telemetry again after abandoning it a while back.

[@waslater]

Ha, I just found your tutorial :)

[@poowap]

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 !

[@JoshuaBardwell]

No. Each receiver can only be bound to one transmitter at a time.

[@poowap]

Joshua Bardwell Damn fast responce Thank You sir ! Bit of a let down but simplifies my purchase list ... Much appreciated !

[@adamk.3946]

And all but one of my quads has an XM+, damn! How do you remove the u.Fl connector? I find it difficult to remove them without potentially damaging the connection to whatever it's connected to.

[@chrispychickin]

You need to stick a decent sized blob of solder on it, and it'll just kinda float away. I usually try to get the blob over one of the 2 side pins, and the centre pin at the same time, and the second side pin will soften up pretty quickly just from the conducted heat

[@JoshuaBardwell]

I'm not sure if you mean to remove the IPEX connector itself or to pull the antenna off of it.

[@norgtube]

Nails under the connector, pull straight up.

[@adamk.3946]

Joshua Bardwell to pull the antenna off I mean, sorry!

[@chrispychickin]

Oh, my bad. there's actually a tool made by hirose that's meant to reduce strain on the ufl, but I find a fine flat blade screwdriver, or credit card or similar is a good subsitute. That or fingernails work too. Also, lol, I see you on reddit all the time Adam, this community is tiny, it's like I recognize half the names who post below these videos!

[@BoysBarn]

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!

[@JoshuaBardwell]

Yellow Smartport wire to the T(elemetry) pad on the CLRAcing.

[@BoysBarn]

And the sbus from the receiver goes to the sbus pad on FC? Or do I just not put it on? Thanks Joshua!

[@StarLiteNL]

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?

[@JoshuaBardwell]

I'm not sure if it would be compatible with Futaba SBUS. I'm not sure if FrSky and Futaba SBUS are compatible with each other.

[@adonisfilipu]

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?

[@chrispychickin]

It's funny no one mentions this when comparing the xm+ to xsr and it's derivatives, the RSSI output on an sbus channel, which unlike the hack where you send it back to the RX through a spare channel, is a real recieved rssi value, and thus is actually meaningful and responsive. I gave up on the xsr when I found that the RSSI signal I got wasn't worth a damn. In dodgy signal areas, it would lock up while still showing a decent RSSI value on screen, thenget control back, all while never showing the dropout. The XM+ has probably the most accurate rssi reading i've come across on an frsky reciever, even compared to using the analog output from other rx's.

[@JoshuaBardwell]

It's true, but personally I prefer the audible RSSI alert you get from the Taranis to one in the OSD. And the XM+ does not give that because it's not sending telemetry back to the radio.

[@WinstonSmith1984]

I didn't know that about the RSSI on an SBUS channel and just found it in the XM+ manual. Thanks for the tip. I just wish FrSky would make their channel outputs user configurable on all their receivers.

[@dronedoutrc5970]

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.
