Purchasing the Tx16s is one of the best decisions I've made in a long time. I absolutely love it. Again more great products:) thank you for the video
Is the boxer 4in1 also good??
Good to know Radiomaster now launched these quite complete PWM receivers. Some months ago I was behind the RM FrSky RXs with pack voltage telemetry but they had been already discontinued... Thanks again Lee for your timely videos! Cheers!
Lee, great review of all of the options. as always thanks for the information and easy to understand explanation. Cheers
Very nice.amazing to see how far fpv tech has come
I just wanted to thank you for reporting the bug I had with the Holybro Kakute H7 Current! Its now fixed and can't thank you enough for reporting that in!
Brilliant! I'm very excited about the telemetry sensor port. Hopefully there will be temperature, airspeed and current sensors coming soon 😀
thanks perfekt explanation radiomaster RE series
Would be nice to have a pwm with simple gyro for fixed wing, like a ELRS lemon rc
Good and useful information, thanks!
Nice to see the 8 channel.
of course I just bought three matek elrs rx w vario .... which were a pita to set up. going to pre-order some of these now.
Fantastic review, Lee! Thanks a bunch! 😃
Those reviews are going to be really useful!
Stay safe there with your family! 🖖😊
Oh yes! They are smart cookies there at RM!
I hope they will release a Lipo Cells voltage sensor to connect to the UART port. To have in the telemetry the voltage of each cells and to have the possibility to set the low battery voltage alarm on the lowest cells voltage instead of the total lipo battery pack voltage. I know you can do it Radiomaster ;-) And also receivers with gyro please !
Very nice, I got boat and RC to upgrade into ELRS.
Very good video and very good news ! I'm excited also with this UART telemetry sensor port ! I think I will change all my FrSky receivers, BYE BYE FrSky !
awesome sauce!
I guess they will produce all the stuff frsky had offered in the last decade from pito tube over current sensor to gps support.
What I always feel hard to understand that the old world has gone as it seems where you needed a 8 channel transmitter to run a 8 channel receiver while now every transmitter seems to be capable of running a 8 channel receiver. But that can not be said enough cause I had missed important things even though watching a lot of stuff cause I had believed I had to wait for a 6 channel pwm before replacing my old world with elrs to fly a plane with tilt and turn camera servo which required 6 channel, 1 motor, 3 plane, 2 camera platform at least.
But I had been not aware that I could use those old matek 405 wing and the new speedy bee wing FC and run all these servers even with ELRS just from the beginning.
I only came across when I looked into the Speedy Bee manual which had emphasized on elrs and wing plus camera configuration .
I even had an elrs radio from radiomaster but was never aware that all of that would perfectly together until this week.
I had not known about those additional or hidden channels that would work once elrs has been bound and connected to the FC.
I am guessing these receivers are finally the ones to replace your old FrSky ones. A while back I remember you made a community post asking if anyone knew of some telemetry receivers that could do the job of some GR8s(?), I guess your prayers have been answered.
Don't think I'll ever build something without a flight controller but I'am still glad these options exist.
You don’t have to build it yourself. Let someone else build it for you. Then you fly it/ run it, etc.
If Radiomaster made these available in 433MHz then people who have been hanging on to systems such as Dragonlink and EzUHF would buy them like hotcakes.
There is a 433mhz ELRS project on the way called TitanLRS. Thought its not using pwm Receivers. I don't see Radiomaster ever making a 433mhz module because their isn't a demand for it. At least not from the quad pilots which are their main demographic.
@@don83030 I agree. I have drones and now i'm back into fixed wing. I just snagged an er6v and er8 and 333hz 16ch/2 is plenty fast for me. That's a 6ms pulse delay, about the same as a decent pc-monitor, which is 25x faster than a nerve signal from your brain to your finger. EdgeTx + ELRS is the future.
This is exciting. One spec missing: throughput amp limit. With 8pwm out used in a larger model (with high draw servos) it could approach the limits of the board. Does RM data show a limit for this?
Edit: I found a few more folks with the same issue, but I also have heard that some folks can see a vSpd in the sensors list. I just got my er6-GV setup today fully expecting to find a "VSpd" sensor on the telemetry screen, but there is not. There is only an altitude readout, no vertical speed readout.
This is so nice !!!! Crossfire should make something like this 😞
I'd love to see a UART on the ER4 as well.
.. Still flying an Openpilot CC3D on a 250mm Grab and Go Quad ; ) , ... might be fun to switch to my Jumper and switch from MY FlySky .. RadioMaster has COOL CLEAR TX too .. cheers!!
The CC3D was an amazing flight controller in its day, it was the one I recommended to new pilots. The setup wizards in Openpilot were fantastic. I wish Betaflight put that much effort into lowering the bar to entry... Happy flying!
Thanks for the video! I still dont see the advantage in using Elrs in pwm. With futaba or spektrum we have a reciever without updates and problems. The range is a thing but in case you flight far you need a FC
ExpressLRS is not for everyone. For pilots that are happy with a closed, proprietary system then it can appear a little complex and unnecessary.
For others (me included) who have been bitten by vendors stopping support for R/C systems when there is a heavy investment to make the customer buy it all again - ExpressLRS is the answer.
This is why the system is so popular. Vendors like FrSky only have themselves to blame for making this look like such a good idea for so many pilots.
These are really cool receivers! Do you need the "V" model to have altitude telemetry?
Yep. V for Vario...
@@Painless360 i put the V variant on a DLG recently. Works quite well.
Checked my local stores webpage,... these all marked as 'New' and 'Sold Out' :D
Did I miss something - no S-Bus at all on any of these?
Very nice video and lovely receivers from Radiomaster with help from the ELRS team, great stuff!
One question, does none of these or maybe all of them support the sbus that now should be a feature from ELRS?
I dunno but would love to see that, have lots of old sbus sensors laying about
ELRS uses Crossfire protocol. Ie when connected to a flight controller you select crsf protocol for your radio link in ,say, Betaflight.
SBUS will be supported in ELRS 3.3
@@lightbulbjim Yes but I am wondering if theese receivers will support it 🙂
@@skylar7320 hopefully it will
Thanks for your video. Would you recommend I switch from Radiomaster 4in1 to an ELRS module plug in back plus upgrade my receivers, to what you just demonstrated in your video? My issue is, the telecommunication tower next to our flying field has been updated, now I and many pilots are getting massive interference issues. Thanks
If the mast is very active in the 2.4ghz band, then most of the 2.4ghz recievers will be affected to a degree. I'd look at something like Crossfire that uses the 900mhz band... See my videos on it.
if I want to have SBUS, vario (altitude ?) telemetry, and lipo voltage telemetry, is ER8GV pretty much the only option ?
I have been using mostly FRSky receivers with my RM. Does this ExpressLRS work with the multi-module or do you need something else?
You would need an ExpressLRS transmitter module like the Radiomaster Ranger
Do you have any idea when they will release this line? Tried looking on the site, but no date on there.
Great video, thank you!!!
I have a radiomaster boxer CC2500, can these receivers work on this radio?
Yes, by plugging in an ExpressLRS module into the rear bay... Best of luck
question: how do you couple two receivers for a dual setup ?
Dual isn’t needed anymore with ELRS. Good for you.
if you have an ExpressLRS transmitter and receiver you have many miles of range, but how do you get many miles of video transmission. Or is the video transmission through the ExpressLRS system? thank you for your nice work, have a good day 👍👍👍
Video link is seperate. See my videos aimed at beginners and the one on flying further in particular... Happy flying
As always nice video! So why exactly i bought a receiver with 4in1 2 months ago?! 😜
To support legacy recievers you already have in your models. Happy flying
@@Painless360 Sure ;)
@@Painless360 would you rather buy the old receivers or a elrs module and the new ones? And, which module?
Are the glider models just built to run on lower voltage and smaller/lighter? Would the ER4 be fine for a standard trainer airplane, providing battery telemetry? Do these have gyro functionality?
Glider models have the ability to work on battery voltage and fit inside slender canopies. Any PWM models will work if you have space.. Happy flying!
Just looking at these for a glider. Does the ext Power source mean its basically used for redundancy. So I could hook up 2 batteries and it would switch if one battery pack failed?
No, that connection is used to get the battery voltage down to the radio via telemetry... Very handy to monitor the flight battery as you fly/drive/sail... Happy flying
I've kept an eye on ELRS. My fleet is mainly Spektrum (from my pre TX16S days), Frsky and Radiomaster, with a smattering of Crossfire. I am going to get a couple of these for gliders that are Crossfire PWM at the moment. Tell me, if I want 6 active channels, am I OK with the 6 channel receiver or is one being wasted on this channel 5 high stuff?
You map PWM5 to another channel, such as channel 7 or whatever. ELRS sends more than 6 channels and you can use whichever of them you want.
ELRS is always 12-16 radio control channels, depending on how you configure it.
The 6/8 channels on the receiver model refers to the number of PWM outputs.
@@stefanpynappels7959 Many thanks!!
@@SuperSeagull12 Many thanks!
Lee, pretty exciting.. but unlike those you mention in your last paragraph who can’t wait to toss all their old receivers.. I find them very reliable so that’s the last thing I want to do.. I must ask is there a way to support D16 and D8 fly sky and Assan at the same time in a TX16S with a ELRS Tx module ? Or must I loose compatability with all my DIY 4in1 compatible receivers to use this.. I know next to nothing about ELRS and wonder if I can use the internal radio to retain legacy compatibility even with a ELRS Tx module installed?
Does the er6 throw out uart signal, i.e., can I connect this receiver to the rx, tx of the flight controller? Also does it throw out SBUS or something similar? Im a noob, but i am choosing components for a fixed wing. Later on i might add a flight controller to the build. Im open to suggestions. Thanks! Great videos btw.
'UART' on the receiver is designed for ExpressLRS sensors like GPS but I'm sure we will end up using them for all sorts. SBUS coming in ExpressLRS v3.3... see my series.. best of luck
@@Painless360 Hey thanks! I just ordered the pocket and er6 for my first build. Looking forward to it. Thanks for your reply.
Are they TXCO? or rather has RM had any loss of connection issues that might be improved with TXCO....Well like my Matek D2400 that lost then regained...at at short range, connection right before the crash!
all er rx are TCXO
Can you link to a information source? I really want to make sure about this
@@sp00fman1 Doesn't say on the RM website. Neither does their diversity rcvr note it. I have only used Matek Diversity rcvrs with fair range, but I did have a recent fail-safe at close range. After that I did the cap removal mod, but looking at the TXCO type. Any thoughts?
I’m having trouble with my ER6GV vario. It’s my understanding that the altitude speed sensor is needed for the vario to function. When I discover sensors alt speed is not listed. I’m picking up 13 sensors but alt speed is not one of them. I have a switch assigned to vario but the tone doesn’t change. I do not have the voltage sensor wire hooked up yet if that matters. Help!
Depends on the version you are using. You may be experiencing a bug
github.com/EdgeTX/edgetx/issues/2546
Please help me understand how to connect a 2Sbattery to a ER4, to power a rudder servo and a rotary winch servo for my RC yacht … connecting one lead to the pad as per instructions does not make any sense !!
That is a voltage sensing lead. Used to send back the telemetry back to the radio... See my video on adding a ExpressLRS RX to an RC car where I used it.. Best of luck
CRSF isn't really an open alternative to S.PORT, or am I missing something? They're both proprietary protocols, right? If TBS get upset (which they have in the past) they could create problems. Am I overthinking things?
See my comment in the video. TBS is allowing CRSF to be part of the open source ExpressLRS project... Happy flying
On the 6 and 8 channel receivers are those full pwm? I though i heard they were limited in resolution or something.
Video about just that on the channel today. Please subscribe and you'll not miss future content... Happy flying
HI, I was wondering if you have created or plan to create a video on how to set a RSSI waring for ELRS? I fly FRSKY and enjoy their RSSI warning and would like to create the same warning? Thanks, Roel
I'm ETHOS or EdgeTX?
@@Painless360 I am actually running OpenTX but Edge woruld work?
ua-cam.com/video/bLsqjDqMF2c/v-deo.html may help.
Finally lol 😂
Do i need to buy a ELRS external moduule if my Boxer is a 4-1 protocol built in? thanks
If you want to connect to ExpressLRS recievers with it too, yes. Happy flying
Are there Pwm receiver without the pins? (Just with the light metal contacts to have less than 3gramms)
I can't think of any that come that way... Best of luck
Hi. Another quick question, if you purchase a radio master tx16s in UK does it matter which one you get ie FCC or lbt and can they both be changed over, I understand the power output is limited for the EU version but is this a firmware thing or hardware? Many thanks
The changes are: for ELRS, limited to 100mw and LBT is enabled, and for MPM you only get LBT compliant protocols if you choose LBT radio.

Dear video uploader,
Would u pls make a video regarding new Matek Hlite if u get one and thanks. 😊??
Will do!
Are you aware of oXs sensor for RPI 2040? Seems like not. This offers full open source sensors for Sport Fbus Spektrum Graupner whatever
Can any of these PWM pin outputs configured to be Sbus Out?
3.3.0 will have serial port selection for SBUS and should work with these..
@@Painless360 Redundant/Satellite receiver and or CRSF to FC via the UART? FC and PWM for servos?
I will cover it with 3.3 is out.. Stay tuned
Daisy chained sensors?
We'll have to see... 😉
Hi, I have a glow model .40 capacity. I want to convert it to electric - any suggestions?
Check out the Motor and Prop series on the channel. We covered all of the considerations in that series... Best of luck
@@Painless360 Thank you.
are they EU/UK legal? lots of Radiomaster accst rx don't seem to support EU LBT firmware :(
It's ELRS firmware, so it's very likely that EU firmware will be available.
They are legal
Good evening Lee, i have a question about the ER8 receiver.. i tried to connect this receiver on the telemetry3 port from my Pixhawk 6C, with all the settings demanded by the doc's in Ardupilot and the Holybro doc's... i probably see something the wrong way... and want to ask you to guide me to the right path.. because i can't/see my radio signal in missionplanner..
Thanks in advance
Regards,
Morris
All I figured out is in this video - ua-cam.com/video/fpnbJPU3hU0/v-deo.html, see the notes in the video description too. I have heard that changing the 'speed' can affect it. i.e. "ELRS can be setup in the same manner as CRSF above , however, bit 13 of RC_OPTIONS should be set to alter the baudrate from 416KBaud that CRSF uses, to 420KBaud that ELRS uses. As mentioned above, the UART selected must have DMA capability."
@@Painless360 Good morning Lee, i have re-done my homework, and rechecked everything.. the problem was a bad connector in my cable, replaced it with a new one and everything is working fine.. even though the ER-8 is a 8 channel receiver, when used on the telemetry-port 3 it gave me 16 PWM channels.. didn't know that.. also used ch12 as flight mode channel, and channel 5 as my Arming switch.. got my 6 flight modes under my 2 switches.. everything works like a charm now.
Thank you for All you do here on this Channel!!
Morris
Good morning Lee, when i set up the failsafe on my ER8 it is disarming.. i mean switch off my radio to test.. this can't be the thing with a copter i suppose.. is there another way to switch to RTL?
Testing on the bench will NOT give the same results as when it is flying. See ardupilot.org/plane/docs/apms-failsafe-function.html Best of luck!
@@Painless360 Hello Lee, Thank you for your reply, i solved the 'problem' , even when my GCS fail's the quad will return to home.. will be happy flying :)
Ok... why are varios banned in 'competitions'?? Why would they do that?
Loads of detail online - i.e. www.fai.org/sites/default/files/ciam/sc4_vol_f3_soaring_21.pdf, section 5.7.2.1 etc.
Sometimes it seems to me that manufacturers specifically do not do what is needed. Thousands of pilots fly long distances - and companies - as if on purpose - do not release receivers for 915-868. It’s a pity. It’s clear to anyone that ANY receiver will work up to 200-400 meters. But for long distances, not any equipment. It’s a pity.
I mean, there are ERLS receivers on that band still (barely) but the ranges achieved on 2.4 ELRS is so far beyond what anyone would realistically require. If the lower band had been what most people wanted the pilots/community and the receiver offerings would reflect that.
Elrs 2.4 will get you miles and miles of range. Clearly you should do some checking the official Elrs range top list
This is a total disappointment. I don't use 2.4ghz ELRS. I use 915mhz ELRS. Where's my 900 mhz band pwm receivers?
Add a Matek CRSF to PWM board, Works.
2.4 is more than enough for 99.9% of users.
You will never reach the limits LOS with 2.4
@@jas-FPV well, for my FPV stuff I am not interested in this range limit. I'm looking for the kind of penetration and range that would reach maybe 20 miles out with lots of overhead powerlines in the area creating excessive RF noise. (Waivers present where required)
@@spartan3299 I just use a Matek H743-WING or H743-WLITE and 915mhz ELRS receiver or now I'm experimenting with TD MX receivers. I have not done a range test yet, so I will not know if that link is as good as ELRS or not for a while. I'm in the middle of a rebuild.
@@cwwisk fair, but sure you don’t fly LOS at 20 miles and for that you have decent options to connect to a fc… so why would you need PWM outputs then?
