My GX12 is ordered along with 5000mah 2s stand and the new receiver with the 4 antenna. I'll order these 1s too. I'll use ya link. Thanks for everything you do for us pilots buddy.
The new standard. This GX radio along with the XR series receivers will replace all my TBS 915mhz and happy model/jumper ecosystem. It’ll be a great addition to the TX16S. Greta review as usual!
This is amazing! I just built my first ELRS quad after using Xfire for years and I am totally impressed with its performance! I've had the boxer since it came out and have always used my Xfire mod on back. It's so nice to shed that Xtra mod on back and even better to lose the long receiver antennas! This new hardware and ELRS dual band is very interesting for my long range setups! Thanks for keeping us informed! Love your channel!
2nd quitter in this comment section!! To good for 50hz huh? I'll pass you at 10 miles out while your in full complete control and I'm hanging on to 50 hz feeling like my quads drunk!! 😮 Hoping XFire comes out with competing firmware soon.
Hmmm.2.4 cannot out perform 868/900 at distance.If "bailing" from Crossfire,maybe just run the XR series on Gemini 868/900 no? I posted up above...love to hear your thoughts about Crossword versus DBR4,XR rx,s if theyre just on 868( NOT 2.4 which is inferior over water at low level.)
So far 2.4 elrs has meet all my needs. I’m pretty happy with it, even when I fly long range. Maybe when my mini talon is finished being built, I might run into a distance that might require 900mhz
I remember switching to elrs from crossfire and being real happy with the antenna size after the price and availability difference. I do medium long range and don't get into situations where the 900 is needed. I totally see where people will want the duel band, but it's not something I need. The lower profile 2.4 antenna is my choice.
Saves the manufacturer a ton of money too, which they can pass on as a price saving, or charge like everyone else and put more money in to their R&D. Mind you, Mad's has put the wrong details in the link to the ELRS Collective's location.
Gemini is same band (2.4ghz or 868/900) but two seperate frequencies for each packet for redundancy. Gemini Xrossband/GemX is dual band (i.e. transmits/receiveds on both 2.4 and 868/900 simultaneously).
@@divingfalconfpv4602 I've not looked at the specs, but depending on what you order you can probably either preference antenna diversity Gemini (same band) or crossband GemX (dual band) - you're basically choosing what configuration the two antenna and RF paths are in. You would need four antenna for dual band antenna diversity (since you need two antenna for each band).
Flown Crossfire for 8 years , the XR1 is less than half the price of the Nano RX, other than OTA for Crossfire I'll be pressed to justify sticking with TBS going forward unless they look at their pricing of receivers. Sitting here now I'd love to see the Boxer updated with Nomand internals and that OLED from the GX12 - that would be the sweet spot for the majority of us I reckon.
XR2 looks to be the one for building sub-250g parkfly models, and the XR4 for nearly everything else, with the XR1 and XR3 being variations to apply where you want a balance between function and mass. Suggestion for content - how to apply the two UARTs in a useful manner?
I understand that a servo wired to a receiver has a positive and negative wire for power and also a signal wire for each channel. I see the pos and neg pads on these receivers and understand each servo would be wired to them. Where are the four signal wire solder pads? Shouldn't there be a separate signal pad ... one for each channel?
I am not too knowledgable on the subject but i dont think these recievers are for servo planes, theyre designed for quadcopters. Radiomaster makes differemt recievers with pins that are marketed for planes.
These receivers are primarily meant to be used with flight controllers. The pads are power (pos and neg) and serial TX and RX (but can be configured for SBUS and maybe even two PWM outs?) If you want to control servos you want the ER series for now.
You could use the first one for SBUS and the second one for DisplayPort (to send arming to O3 if your craft doesn't have a flight controller). On a typical FPV quad you don't need it.
Ian....would I be right in thinking the XR1,3,and 4 would be as good as a Crossfire Diversity Nano RX (IF) I used them in Gemini mode in 900mHz? I fly over water at LOW LEVEL,mid to long range normally...hence my Crossfire preference at this moment in time,however,I'm open to change!
It all gives a easy pathway off the 2.4 and all the congestion provided I'm happy to move to a new radio. I'm just using the pocket since moving to ELRS so it's not like I have a vast investment. Just want to play with how easy it is to switch frequency per model. It's not worth long range anymore in the UK with current legal state but I would have killed for these back in the day. It's increasable just how affordable it has all become.
probably missed it (fast forward trough the vid to scan for all basic info) what is the RX2/TX2 extra uart for? to control a cam on a gimbal/servo for example? great video btw, I know what my next go to ELRS receiver wil be for both quads and Fixed wings, thank you Ian.
Help: i fly helis small ones..wanting to go into fpv got the neo and torn between buying dji fpv controller and radiomaster and honestly confused already
Can I put dedicated frequencies antennas, one 2.4ghz and one 900mhz if I set the settings carefully on the XR4 ? I would get a bit better performance with specialized antennas. What would be the point of the DBR4 then, aside switching Gemini frequencies by software with 4 antennas.
Its crazy to see some receivers now getting as many IC's as some AIO boards. What really comes after this for ELRS? Approaching end-game for its purpose.
Is there any reason someone would still buy the RP2 V2 reciever over the new XR2 nano? I guess the RP2 weighs a little less but it costs twice as much now
Thanks Ian, good overview and an interesting and well priced product offering. But I am still confused. I fly 2.4 ELRS and 900 Crossfire and I have never had range, penetration, interference or a fail safe from either one. Why would I want to buy another radio or module and new receivers at this time? Perhaps you can cover that in your next video.
When you are flying longer range and/or certain RF environments, this is when dual-band/crossband can become useful, as one band might go deaf, and the other still work, and then they may fade in and out differently as harmonics and conditions change. If you don't have any issues with your current setup, no need to look further though. :)
It may, but since it has four seperate antenna connections, two for 2.4ghz and two for 900mhz it would be a step backwards with that RX anyway since you have dedicated antennas for each frequency band. Dual band antennas are a compromise - you trade some performance/sensitivity for compactness.
@pfeerick Yeah, you're right. But I saw a reviewer in Indonesia doing a test with a Nomad and a DBR4 receiver, each using dedicated 2.4GHz and 915MHz antennas. He got an RSSI signal strength of 20-30 dBm from a distance of 4 feet. After confirming with Radiomaster, they stated that the 2.4GHz antenna is still for 2.4GHz, but the 900MHz antenna has two links: 900MHz and 2.4GHz. I don't understand if that's true or not, and whether it can actually affect the signal. I hope Ian can do the test 😅
@@teukurezas that sounds more like some crossed wires .. the DR4 has 4 individual antenna, whereas the NOMAD has two dual-band antenna... but we'll know more as it gets documented properly rather than having to be an ELRS dev to know what is going on 😂
I will say the ELRS firmware is definetly surpassing crossfire in certain aspects. But the quality of the hardware just seems to be lacking in comparison. But i guess if it works, it works...
Right now I can't see any reason to buy a receiver from anybody else. You aren't going to find them cheaper, and certainly not with the same capabilities. Kind of absurd, blowing everyone else out of the water.
Don't wanna ruin your elrs party 😅😅😅 but crossfire will still be around for a long, long time to come. Be all means i am using also elrs and gave my crossfire to my mate for some long range stuff 😂😂😂
I got rid of all my crossfire when my middle broke and everyone was out of stock of crossfire modules every where. Waited like a week then decided just to switch everything. I already had extra elrs receivers
I'm glad you have a link to use. I was about to buy some and wanted to help support someone I respect in out community.
Fantastic review, Ian! Thanks a bunch!!! 😃
Merry Christmas!
Stay safe there with your family! 🖖😊
Great job mate, radiomaster stepping up the game, I was running the RP3 for awhile , no issues at all.

Thank you Ian, you and gamer nexus are the only people on TH-cam I trust.
@Mads Tech Ian, how does the RF filter work with dual band? Are there really dual band filter ICs?
Yes, there is a dual band filter that passes low band out one pin and high band out the other.
I remember switching to elrs from crossfire and being real happy with the antenna size after the price and availability difference. I do medium long range and don't get into situations where the 900 is needed. I totally see where people will want the duel band, but it's not something I need. The lower profile 2.4 antenna is my choice.
Trader!!! Crossfire for life!! You haven't lived yet when 3 miles out 20 ft off the ground at.......50hz!!! It's a rush!! 😅
Open source always comes out on top
Especially for platform technology
Saves the manufacturer a ton of money too, which they can pass on as a price saving, or charge like everyone else and put more money in to their R&D.
Mind you, Mad's has put the wrong details in the link to the ELRS Collective's location.
Good video, happy holidays..
RadioMaster is leading the ELRS charge! ELRS is RadioMaster and RadioMaster is ELRS. Not much hardware competition at this point
So Gemini auto switched frequencies? The multiple frequency ones you have to switch manually?
Gemini is same band (2.4ghz or 868/900) but two seperate frequencies for each packet for redundancy. Gemini Xrossband/GemX is dual band (i.e. transmits/receiveds on both 2.4 and 868/900 simultaneously).
@pfeerick just was confused because one of the receiver says Gemini and the other receiver just says multiple frequencies

There Are plus, minus, extra and tx. They are ment to get sold to a flight Controller board. You cannot control an actuator directly.
These receivers are primarily meant to be used with flight controllers. The pads are power (pos and neg) and serial TX and RX (but can be configured for SBUS and maybe even two PWM outs?) If you want to control servos you want the ER series for now.
They are full duplex uarts
How do you configure the extra uart?
What's the use of the second uart on the rx?
You could use the first one for SBUS and the second one for DisplayPort (to send arming to O3 if your craft doesn't have a flight controller). On a typical FPV quad you don't need it.
@jiatan_fpv so this is basically for boats, crawlers and planes.
Ian....would I be right in thinking the XR1,3,and 4 would be as good as a Crossfire Diversity Nano RX (IF) I used them in Gemini mode in 900mHz?
I fly over water at LOW LEVEL,mid to long range normally...hence my Crossfire preference at this moment in time,however,I'm open to change!
Latency test through all the modes? UAV tech started doing this but seems to have let it go before all these new ELRS links appeared.

Could you make a breif (if possible) video on the sorts of hardware you would connect or could connect to the uarts and maybe how to set that up?

better telemetry and more channels, probably.

Are these better than the RP? I just got the Nomad and was about to buy the RP versions. I'm thinking these are superior?
If you want to utilize crossband, then yes these are superior.
Great info thank you
Ian, is xr4 capable of full Mavlink?
seems like not long ago i purchased the latest receiver with the 4 aerials for my nomad. bright side they not to expensive to keep up with the latest.

Hey Ian !!! Can we fly these products in Eu somehow?
Yes you can flash them with EU firmware that supports LBT.
@MadRC thanks!

Cool!
discount code?
I will say the ELRS firmware is definetly surpassing crossfire in certain aspects. But the quality of the hardware just seems to be lacking in comparison. But i guess if it works, it works...
I'm intrigued why you think the quality of the HW is less. Everything iv seen says it's onpar or more
So need for 5 in 1

Im here to say, eachine just drop a module for open ipc
I think they did that a while ago
Now They just have to make 433MHz hardware. And we prob don't need anything more

stop shouting please
He does come across that way, odd though, the audio is never clipped or distorted, so it's recorded and edited properly, just a little over excited :)
Have you tried turning your volume knob counter-clockwise?
You completely lost me with the alphabet soup mix with the numbers. Guess i have not been in FPV long enough, talked me out of new radio for now.
