25km FrSky R9M and R9 868Mhz long range system test (EU legal)

[@alasdair4161]

That system is worth serious consideration over more Dragonlink receivers, not much more for the entire system and any additional receivers end up being way cheaper. Great review again, and thanks.

Thanks mate! :)

[@ArxangelRC]

Thanks mate! :)

[@flyingrock6381]

good to see this system working! cheers!

[@ArxangelRC]

So am I! :)

[@rf2632_]

Why is everybody complaining about the failsafe issue on short distance with the R9M ? I cannot find discussions or videos regarding this and your video shows that the EU firmware is quite stable. I havent tested mine yet as I am still building my first quad. Thanks!

[@ArxangelRC]

Not sure why that is, although granted, I am using it on a plane! In quads antenna placement is even more important as everything is packed so tightly in there!

[@haggfpv8715]

Thanks for this awesome test. You gave me some faith in this system. I bough a TBS Crossfire Micro TX and I'm really disappointed! Even with the diversity receiver on 100mw I get RSSI low warnings (RSSI/LQ in the osd also drops down to like 50%) at 2km. Once I even failsafed. 2km were easily possible with my FrSky x4r (Rssi was stabel around 80%) so I don't feel any real improvement. I though about buying the big Crossfire TX but that would be an extra 108€ over the Micro TX. I don't wanna go out further than 5km, I still chose to go with a longrange system to have extra security when flying planes that do not have RTH. Now I may just try out this system.

[@ArxangelRC]

Thanks mate. Actually the L9R receiver ( goo.gl/76N7Sf ) should give you plenty of security out to 5kms, unless you like to fly low behind trees. I've been able to get out to 22kms with it, without loosing the signal... I can only assume 5kms will be quite trivial for it!

[@haggfpv8715]

ArxangelRC yeah you may be right. I'm actually currently using an l9r receiver in my wing and had no problems. But since I'm also now starting to fly a bit further away with my miniquads a long range system just gives extra confidence. Also considering the price difference between an r9 and l9r receiver it seems worth the extra confidence I would gain. I once Fail-Safed at 1.8 km (x4r) over a forest and my quad fell to the ground. I was able to find it but the experience wasn't very pleasant and if possible I want to avoid another crash at longer distances.

[@ArxangelRC]

Yeah, in that case the R9 system is the way to go! It hogs the battery of the Taranis like crazy though, just something to keep in mind! :)

[@TeamBlackSheepFPV]

the Crossfire system, when installed like in this video (foam plane, plenty of spacing with components, etc), will easily give you 20km on 10mW power setting. please keep in mind that with 900MHz systems the installation and RF profile performance matters a lot, not the output power.

[@ArxangelRC]

That is true! Will have to actually switch to the 25mW mode and see how far that will get me! :)

[@DerrickWoolworth]

Thank you for doing this review - I own the R9/R9M but have been a bit worried about using it. Seems great! Would really like to know more about your ground station and what video receiver/antenna combo you're using.

[@ArxangelRC]

Thanks, yes, I have it on my To-Do list to do a video about the ground station! It is a mess right now, but either way... people will get an idea what I am using.

[@ehsankeshtgar6734]

Another great video . Thanks. Do you know if L9r module that works on 900mhz will interfere with 3dr telemetry that runs on 900mhz ? Have you used any telemetry system to suggest? Thanks in advanced.

[@ArxangelRC]

Interestingly enough, I have used 900Mhz telemetry along with the R9 module... and since you can tune the telemetry's frequency range, I tried to move it out of the R9's range, although I am using the EU firmware for the R9, so it is running at 868Mhz, not 900Mhz! I have not seen it affect the R9, but it is possible the R9's telemetry, if enabled, might have an effect on the telemetry module!

[@mrt136]

Very Nice review! I got a full size X-Uav Talon recently and am looking for a long range system. Looks like it perhaps is gonna be the R9 system. A question: n the video at 4:22 there is some fast forward video, the shaking we see is it drifting in the Z axis at the gimbal or the plane not going straight? I'm asking because I recently build a 3D printed gimbal with a StorM32 controller, in some settings the Z axis drift a bit and go back.

[@ArxangelRC]

Nope, not a drift of the gimbal. The plane's rudder PIDs are not very well tuned... which is driving me nuts when I review the footage... and I always forget to try and get that sorted!

[@flighttherapybullisticfpv133]

You should really look into the Furious FPV 2.4ghz video system... it has a bit of an issue switching between the diversity antennas but seems to provide crystal clear video with a patch antenna out to 12km at least... if you get a DOCK-KING you can mount it in that and use it as a ground station... LOVE your channel man!

[@ArxangelRC]

Thanks mate appreciate it! Thing is... even on 5.8Ghz I am starting to push 30kms now... and I think it can go a lot more... so not really ready to switch to a different system yet, but it is good to know there are options! :)

[@flighttherapybullisticfpv133]

@@ArxangelRC i just saw another video where a guy got 25km of super clear video with the 2.4 system. Looked like he could have gotten farther with a bigger battery judging by signal quality. Still despite firmware updates it looks like the antenna switching problem is still present so maybe better to wait until they have that ironed out its a fairly new product

[@ArxangelRC]

Will keep it mind and wait for the right time! But like I said... there is time... I am still not done with 5.8Ghz! :)

Awesome video. Did you allready perfom some more tests also with the smaller receivers ?

[@ArxangelRC]

Thanks! Have not yet sadly... waiting on an R9 Mini to arrive and should be able to do a few more tests!

[@RCstagram]

Do you think the T antenna of R9 receiver should be mounted vertically like you did? Or horizontly? I’m confused.

[@ArxangelRC]

Vertical! T is only the shape, doesn't mean it has to stand upright like the letter T!

[@RCstagram]

ArxangelRC understood. By the way, we should consider the trasmitter antenna rf pattern which is the super-8 antenna of r9m. What do you think about this point?

[@ArxangelRC]

Honestly... I have NO idea how that Super 8 has to be oriented... have not looked into it!

[@MrSalvoFly]

Hello. I soldered on the p4 pad of my R9 frsky receiving, a cable to send the analog Rssi signal, to my hobbyking Mini osd, with modified firmware. But the value that reads it does not go beyond 53%. On my X9d plus radio, the value I read is 100% If instead I connect to my mini osd, the output of the L9r receiver always frsky the value goes to 100%. I did some range tests from the radio, and the Rssi value coming out of pad p4 is as if it had a half scale. I also did the test on other 2 mini osd with the same firmware, with the same result. The mini osd has a potentiometer to calibrate the RSSI but acting on it does not change anything. What do you think about it? Thank you for your time.

[@MrSalvoFly]

I forgot, the - gnd that the mini osd wants to display the rssi, i got it from the s port. I also tried it from the pin -gnd servo. - gnd to sbus, don't vork.

[@ArxangelRC]

Hi, well the analogue RSSI output on FrSky is 0 to 3.3v, so I would assume you need to enter the correct values in the OSD for it to scale it properly!

[@hb9hal]

Diversety means, you should install the two Antennas in separat polarisation ( H/V) or divided from each other. Contact a local Ham-Radio-Operator to measur your SWR ( Return Loss) of your Antennas and you will be surprised to reach the moon! If you just improve your RX-Antenna gain +6dB, it will double your distance. I also recomend a super low noise Pre-Amp @ 0.4dB NF.

[@ArxangelRC]

During my flight, at no point, when I was at distance, was the plane banked more than 5-10 degrees... what good would a horizontal antenna be??? Especially when the antenna on the ground is vertical as well! As it is now... the video system is the limiting factor by a long shot... so at this time I really don't think that improving gain is really needed. If my video system ever manages to out-range the R9 receiver... then I will consider improving the antennas, or adding that Pre-Amp thingy! :) Thanks for the suggestions though!

[@JulianGoesPro]

totally get your attitude, but why mounting the second antenna than​ at all? Less drag, less weight (not that I think the later would count in RL)

[@ArxangelRC]

With these flat antennas... I always keep thinking that they might be a tad more directional in one of the sides... so I mount them this to make sure that at any time, at least one antenna will have its more directional side towards the Tx on the ground.

Hi, just curious if you ever tried a 1.2ghz video link with the R9m system. I am having serious video interference with the R9M module standing next to the video receiver. No idea how to solve this problem. Your inputs will be quite valuable for me, and all of us trying to use 900mhz and 1.2ghz together.

[@ArxangelRC]

As far as I've heard and read, these two frequencies do have an issue working together... at least without some filtering, or something!

[@EnglishTurbines]

The solution is easy, use a low power 5.8G vtx on your Ground Station to relay the signal wirelessly to your Goggles or monitor. This way the 1.2G Video receiver is kept well away from your RC Transmitter. I use this method on my EZUHF setup for the same reason.

[@windwalkerproductions]

If you have an open channel you can output RSSI/run a single wire from the signal pin to your OSD/FC.

[@ArxangelRC]

How would that work?

[@kral5932]

ArxangelRC if it has telemetry, you can set rssi to output on one of your 16 control channels, in the channel mixer, just set the source as rssi.

[@ArxangelRC]

Oh.. that scheme! Well... can't. EU firmware only has telemetry on the 25mW power output option. Besides... not really a problem to open it up and solder a cable... it was a 1 minute job! :) Plus, the APM I am using in this plane works well with the analogue RSSI, and was already setup for that.

In this video I am using a Pagoda that was made locally here to test the concept, but that was a while back! Right now I use the GEPRC Pagoda 2 antennas, and am exceptionally happy with them! You can find links to them in some of my more recent ZOHD Talon GT and X-UAV Clouds videos!

[@glumfish6862]

How much VTX power would I need at 5.8GHz to go about 10km? (With a fatshark diversity module, patch antenna and cloverleaf) Would the AKK 1.2W be a good option? Also how much power would I need on the telemetry radios for the Pixhawk I was thinking 500mw? Thanks for all the advice. Great video!

[@ArxangelRC]

Yes, it should get the job done! With my antenna tracker I have been able to get 14 kms out of 200mW... but with the goggles you might not be able to point the antennas quite so accurately! This Vtx just might give you that chance, but keep in mind quality antennas are a more important than power output! As for the telemetry... with good antennas 100mW should be more than enough... then again... if you don't have any directional antennas... perhaps try the 500mW versions... and lets hope they work!

[@glumfish6862]

ArxangelRC Okay thanks. Would you recommend another plane instead of the Talon from what I'm looking to do? I will research the Omnibus but I think I'll take the Pixhawk 4 mini because I want to learn how to use it (then I can move all the equipment to a bigger plane). You have been very helpful many thanks.

[@ArxangelRC]

Which talon? The big one, the Mini Talon, or the Nano Talon?

[@glumfish6862]

ArxangelRC The Nano Talon. Since I saw the Dart XL review (great video) I have started learning to wards that even though I am a plane begginer. Which would be best?

[@ArxangelRC]

Between the Nano Talon and the Dart XL... the Dart XL is hands down the better plane... not sure the best one for a complete beginner though!

[@atw98]

Have u tried the R9, as I just got one without the JR module? I have mine bindded and ready to go just wounding if you'd tried it just of the controller? and if that increased you distance at all. as We have bad weather for the next 2 weeks would love to know. It bound easily to my qx7 internal TX. Cheers.

[@ArxangelRC]

I am pretty certain the R9 will NOT bind to the internal module of any of the FrSky radios! The R9 system operates on 868/900Mhz, while the internal modules are 2.4Ghz! Completely incompatible! Don't you mean the L9R receiver: goo.gl/76N7Sf

[@atw98]

Yep you can I have. you need to bind it to L12 and it works great don't know where you got your info but its even in their extensive, ha ha, user guide. Just go to internal RF settings set to L12 bind as normal. Have mine setup with Pixhawk works a treat. But thats on the magic qx7 100%. It even tells you to bind internally to L12 on the xd9 internal RF sedtting. They are 68 from Bangood and we get them for 40 in Australia crazy. going to double check my prices from noe on thats a rip off :)

I still think you are talking about the L9R receiver! There is no way you would be able to bind a 900Mhz receiver to a 2.4Ghz radio!!! Can you show a video of this working?

Is telemtry on or off for this flight? and will turning it off give you overall better range? or once it gets out of range it will just say telemtry lost but still have radio to the plane? im not too sure how that works?

[@ArxangelRC]

Telemetry is off, because this was done on the 500mW option, and for the EU firmware it has no telemetry! As far as I can tell... people who try to use telemetry do have worse results, which is expected... Usually for my Graupner radio, when I lost telemetry that didn't cause a failsafe, the radio link was still good! For some reason FrSky gear goes into failsafe the moment telemetry is lost... so even if you have radio... it will go into failsafe... at least that is how I think the protocol works based on my observations!

Hey Nikola, my R9M arrived and all is good however I can not set failsafe on the module or receiver. I have Turnigy 9xr. Could you please let me know of the procedure? Thank you.

[@ArxangelRC]

Not sure how failsafe is setup via the module, but for the receiver, once you have set the conditions you need for failsafe, press the button on the receiver for a second... that should do it... or at least it did it for me.

[@FPV420.]

Thank you Nikola. In fact I managed to solve this issue after lots of troubleshooting but here is what I've found. Firstly, you need to have FRSKY QX7 in order to set failsafe.Then the firmware must be the newest available, otherwise the menu for failsafe won't be there. Once flashed in the menu of the model you're flying you have to turn the internal module off and enable the external module i.e R9M. Lastly in the menu of the model from "failsafe" option you may specify if the action is "no pulses", or last values or custom. After all that you may use other type of JR compatible radio like Turnigy 9XR.

[@ArxangelRC]

Right... that failsafe works only with an FrSky radio, because only it can communicate with the module that way, the other radios just don't have the hardware necessary I would guess! Glad you figured it out though! :)

[@brubakerjm]

This will plug into any radio with a JR module bay (Turnigy 9X, 9XR, 9XR Pro, Taranis anything, etc.). 900mhz RC links (such as TBS Crossfire, and this one) have been known to cause significant problems with 1.3Ghz video setups. You may want to do some more research and figure out if your planned setup will work. Most people flying 1.3 video are using 433 for control.

[@DivisionRc]

will it interfere with 2.4gz video? Since the 2.4gz on the radio will be turned off?

[@brubakerjm]

You should be good to go with 2.4 video.

[@ArxangelRC]

Yeah, I think you should be good with a 2.4Ghz video, but then that may be influenced by the amount of wireless routers in the air, unless you are somewhere out of town, where there is no interference!

[@RudixSA]

You should never setup the 2 RX antennas like that! You might as well only have one, they should be 90deg to each other. Also black printer filament contains carbon that can and will shield the antennas.

[@ArxangelRC]

How much of the antenna does it actually shield? Have not seen any reduction in performance... as you can see! This antenna setup has worked for me over a number of years... so out of experience I'd say I am pretty happy with it and don't see the validity of "...should NEVER setup..."!!!

Could be at these higher power levels the receiver gets swamped from the radio and it can't bind properly!

Hi thanks for the reply. i tried to put the transmitter far away from the reciever to bind, but unfortunately it doesn´t work. Not in 200 and not in 500mW. i think maybe they restricted this with their latest firmware? can you tell me what firmware is on your module and reciever? or, if not, when did you buy it? i try older firmware! and you are right, never change a running system.

[@ArxangelRC]

Can't remember now which version I used, but it is at least 3 months old... try some of the older ones, but you will have to flash the receivers with the corresponding older firmware for them as well! :)

[@du4-fpv777]

I have mine bound but when I plug it in it keeps beeping and I have no controls... Any ideas? I have telemetry...

[@ArxangelRC]

What model is the receiver? Are the firmware versions of the receiver and radio the same?

[@abdulfpv3363]

Hello my friend, are you use r9m first launching without add xt30 power in the back module. Is range still okay? Can you explain Thanks

[@ArxangelRC]

My module does not have the external battery connector on the back, so I power it via the integrated Taranis battery - a 3S LiPo.

[@abdulfpv3363]

ArxangelRC ihave same, oke iwill use 3S lipo. thanks my friend

Good luck! :)

[@abdulfpv3363]

ArxangelRC by the way when you test new receiver r9 mini with module r9m. I will wait your next video about r9mini. The size like nano receiver tbs crosfire

[@ArxangelRC]

I will try to get some as soon as possible! :)

[@RudixSA]

Your antennas are not optimally mounted for a diversity RX, they should be 90deg to each other. The way you have it mounted you might as well only have one antenna. I have been using the R9M system since release and I love it!

[@ArxangelRC]

Well diversity is more applicable where there is 3D flying... I fly level, at distance... hardly see the reason to mount them otherwise given that at distance my turns rarely happen at more than 5 dergee roll, so for my purpose, they are properly mounted! And yes, R9M has been brilliant for me as well, really like it!

[@marwans4018]

can i use r9m module on any rc transmitter ? or there is specific supported rc transmitters ?

[@ArxangelRC]

You can use it on any radio that has a JR style module bay at the back. Alternative you could try to DIY some wiring thing to hook it up, but it will have to hang outside of the radio if it doesn't have this module bay.

[@macieks.5959]

I have very similar setup of r9m and r9slim+ and today I had like 60-70% of rssi after 170 meters! Using lgb version of firmware on both module and receiver. Can't yet tell what is wrong.

I've heard that the TBS Diamond is a very good replacement, although I haven't gotten one yet... though I am planning to at some point, when the stock one starts lacking in range! :)

[@AetherealSea]

Would you use two TBS Diamonds and if so how would you consider orienting them?

[@ArxangelRC]

The Diamond is a Tx antenna... not sure how that would work on a receiver!

[@AetherealSea]

ArxangelRC My bad. I am putting the R9 on an Opterra and too focused on replacing the dipoles with higher gain antennas.

[@ArxangelRC]

Actually I wouldn't replace the receiver antennas, but I would put a Diamond on the Tx, though I think it is a bit directional.

[@LEGBAFPV]

[@ArxangelRC]

Thanks! :)

[@kcliu7130]

Do you need to rebind receiver by changing output power from 25mW to 500mW?

[@ArxangelRC]

Used to be like that when I last bound these two together... haven't updated since then, so I can't say for sure, but I think the new Flex firmware changes the output on the go automatically... but you need to have telemetry running for it to work properly I think! :)

[@kcliu7130]

ArxangelRC yes, I did try OpenTX 2.2.2. I did not rebind and change to 500mW. I also used Soectrum Analyzer to test the output power as well, it’s around -12dBm which is good enough to see the difference. Later I flew mini Talon for 5.4KM until VTX break down. The RSSI warning came about 4KM for like 1-2 seconds, and quickly regain RSSI. I did not try 1W output since it begin to have low level noise generated from R9M module. The sounds make me uncomfortable, I decide to give up 1W and stay with 500mW.

[@ArxangelRC]

500mW has been perfect for me for over 27km... Should work well. :)

Hi. I notice that you use my fly dream aat. System. I have burned twice osd bought on eBay. Do you have any video or manual that show the correct wiring of that osd ??

[@ArxangelRC]

Not really! The official manual for the TeleFlyPro is pretty good! Not sure what was the issue! How did you burn them?

[@franklee90]

ArxangelRC. just following wiring diagram at the manual :( chip begun to getting hot to burn.

[@ArxangelRC]

I've also burned out a few, but I figured out why! When I power everything with a single battery, and use a common ground, I used to have two separate plugs for the AP system, and the video system. If I don't plug all at once, but plug the video system later, the TeleFly OSDs were getting damaged for some reason... so I stopped doing this! Could it be a ground loop issue?

[@franklee90]

ArxangelRC thanks for your response. I don't know yet the answer. I'm going to try again in the future but need to be sure what's happened.

[@ArxangelRC]

Hey, burned out 3 boards before I figured out that was the issue. Never had a problem since!

[@leonardvdj]

Could you possibly test the frsky r9m lite? I want to get x-lite but also want to be able to do long range for planes.

[@ArxangelRC]

The Lite only goes u to 200mW... I can test my module at that power level... and actually I have been doing that with the Mini AR Wing! With the R9MM receiver I get over 5kms easy, with proper antenna placement... what ranges are you looking for?

[@leonardvdj]

@@ArxangelRC No range specifically, I probably won't be going past 5km. I just don't want that to be the limiting factor because I chose the lite over the normal. Can always get a x-lite to JR module adapter, it just doesn't look & fit as sleek as the lite module :P

[@ArxangelRC]

I think you will be more than OK with the Lite module, 200mW should be able to easily cover that distance!

[@leonardvdj]

@@ArxangelRC Ended up getting a secondhand earlier version of the r9m full, EU version. How much do you need the xt30 on the module itself? The version I bought does not have the xt30. Can I just put a big / external battery in my transmitter? Also, what antenna do you have on the module?

In the video description there is a link to my blog, in the parts list there you will see them - some 580Kv ones.

[@handle-with-care]

Thank you! I have been searching the internet for over half a year now, but the only good quality low KV brushless motors I could find were from Sunnysky. Unfortunately they are expensive and can only be ordered from China or the US. The Racestar motors seem like a good solution as I want to build a motor glider with long flight times. What is your experience with them or can you recommend any other motors?

[@ArxangelRC]

Weeeeell, the price of the SunnySkys is justified... they are good quality. T-motor is another good motor, but even more expensive. Racerstars are OK, but their bearings are not very good... need lubricating or possibly replacing after very little use... which really makes the SunnySkys not that expensive! Usually the higher the prop, and the lower Kv the motor, the better the flight time, even on a fixed wing! :)

You got functional FPV video at 25km with a 600mw 5.8ghz vtx?!

[@ArxangelRC]

Yes, and I think it could go even further with the right antennas.

[@EnglishTurbines]

Outstanding, not surprising though with 500mw of RF output...Im guessing having a 5.8G video link helped. Are you sure the EU LBT rule is 500mw..?.....I would have thought 10mw is more like the legal limit knowing those meddling idiots..?

[@ArxangelRC]

Hahahaha, no idea what the max allowed output is at that frequency... but there has to be a reason why the EU version has been castrated like this! 5.8Ghz is a great frequency... doesn't interfere with anything else...

[@EnglishTurbines]

I think if you investigate, you are not allowed to run your TX above 10 mw....maximum RF output. If you are using a Horus Transmitter, it has RF power pre-sets, starting at 10 mw for folk like you in the EU...!!!! 5.8G is a great video frequency, if you like flying distance on the edge of space....lol. Dragon Link receivers are not as resistant to 1.2G Video as the EZUHF system. The DL Transmitters are also known to be dirty sideband generators and also affect 1.2G Video receivers if they are too close.

[@JulianGoesPro]

EnglishTurbines I am pretty sure it’s 25mW, you can put the CorssFire Tx in CE mode and I think that limited it to 25mW max power (so it jumps from 10mW to 25mW when needed)

[@ArxangelRC]

Well... 25mW isn't going to get us anywhere... so a good job they included that 500mW option... but while they are at it... might as well give us the same functionality as the FCC one... could be without telemetry... don't care about that anyway! :D I actually am using the international firmware on my Taranis and 2.4Ghz receivers. That EU firmware for those is no good in my eyes!

Many people have a crossfire, its a good/proven system.. This one is way cheaper, is supported by FrSKY and doesn't need a PC based program to run updates. I appreciate this video and would like to see more people having success/reviewing this as it's a lower cost option and has insane range.

[@JulianGoesPro]

is it that much cheaper? With "high key" quad races requiring to use crossfire it became a no-brainer for those but with "LongRange" it's still not that common like Dragon Link or EzUHF (is that still a thing lol? :D)... what I am curious now... you say "doesn't need a PC based program to run updates", how does FrSky solves that "problem"? I mean the CorssFire Tx can flash over the air the receivers which I already did and love, but true, you still need a PC to update the FW on the Tx module, does FrSky offer you to just "drop it on the Taranis SD card" to update Tx and Rx?

[@windwalkerproductions]

It's $75 for the R9M+R9 Slim.. 1/2 the cost of a crossfire micro bundle and 10 times the output power. Since the R9M can output 1W it's more comparable with the big $210 full-size crossfire. As you said.. updates are done by dropping the files on the Taranis SD card.
