If you feel like building a 5" Freestyle Drone is too hard, you just need the right guidance.
So, I built a course with 71 highly detailed but simple modules, breaking down absolutely everything! They're can't be anything missing, if there is, I will add it. Many companies make ExpressLRS hardware, are they ALL compatible?
In this video, we will go through which ExpressLRS receivers are compatible with which ExpressLRS transmitters. We will also cover how to ensure you buy compatible gear!
Use this to ensure your CLI DIFF is BetaFlight 4.3 safe:

Important to flash everything with exactly the same version firmware. Not even minor versions are entirely compatible. Later versions have better features but many devices lack space for the code, it would appear.
The major oversight in ELRS is the diagnostics on the web site on the RX side. Signal info is really important if things don't work first go and just knowing if the Tx Rx is bound, is critical if you get no response.
I think this is why Configurator offers the firmware version first. But, next time you buy an RX you likely want to use the latest firmware version, DON'T!
Link not working
"...and Free sky, well that's doesn't even work with Free sky." 😂
So true.
Love the new editing/effects style!
Thanks. It too a lot longer but I am happy with the outcome.
SUBBED!!!! THANK YOU! My lord is it hard to find concise digestible and complete info on a given subject within fpv without having to essentially binge videos or watch a "show"...kudos.
Thank you! Yes 🙌 I want to keep things to the point
geeez the editing and effects looking amazing!!!
Thanks Sway
Thanks for this video.
Very informative.
Well done
Thanks Jack!
Kind of a misleading video don't you think..? You made it sound like not all elrs modules and recievers work with each other. But they do, as long as they are the same frequency and are all setup properly.. Obviously!!.
If you go to the ELRS Facebook group there isn’t a day that goes buy where someone doesn’t ask: does _____ work with ___ . Is it misleading to provide the answer in a video?
@@DarrenAllatt the way you said it implied that not all elrs modules and recievers were compatible.
@@JP-qq2kn but they are not, as you rightly said. You have to match frequency and version.
So all the elrs hardware will work with each other ? eg. Happymodel TX with iflight Rx
Yes. As long as it’s all the same frequency
Thank you so much!!
I'm just starting out, is ELRS all I'm gonna need? I already have a T-Lite with the 4-in-1, but I'm seriously thinking about just getting the T-Pro with built-in ELRS and selling my T-Lite instead of buying a bulky addon module that barely will get enough power...
Are the SPIs elrs 2.0 ready or do we need to flash/upgrade these?
You will need to flash Betaflight 4.3 when released for ELRS 2.0 on SPI
I'm totally confused about radiomaster! Are the transmitters compatible with spektrum?
The JP4in1 version of radiomaster radios is compatible with Spektrum
And that's all there is to it. Simples!
T motoer P50A esc will be enough for T motor pacer 2207 v3 2550kv
Assuming you are flying 4S? Or will you be using 6S?
BETAFPV ExpressLRS ELRS 915 mhz will work with happymodel ep 2 rx 2.4ghz
No. As I said in the video - 2.4ghz doesn’t work with 915mhz… you need both TX and RX to be on the same frequency, and you can’t change the frequency, so you’ll have to either buy a new 2.4ghz TX or new 915mhz Receiver
@@DarrenAllatt thankyou for the help 😄
@@DarrenAllatt which one is better for high interference area happymodel ES 24tx pro vs happymodel ES 900TX?
@@umeshkumarravi8243 technically 900mhz will perform better than 2.4ghz from a penetration perspective as the lower frequency can get through solid objects more easily, and is below the noise caused by wifi networks.
The point to remember is, your video is 5.8ghz so that’s going to be the weakest point, from a pure transmission point, and more especially in a noisy RF and dense environment anyway.
You’ll have more benefit from choosing 2.4ghz over 900mhz because your video will fail before your 2.4ghz radio link does.
So go with 2.4ghz
@@DarrenAllatt thankyou for the proper explanation 😄.
The refresh rate needs to be the same also no?
Refresh rate is set by the transmitter so the receiver will adopt the refresh rate of the transmitter.
@@DarrenAllatt did not think that this was the case for spi ones?
I'm just hoping I can buy a transmitter that has ELRS built in as a protocol choice or a ready to select module and solder in the ELRS receiver into my drone then simply bind and fly after it is all set up properly in Beta Flight. No flashing and upgrading just simple like it's normally done with my Skyfly or FrSky models. Think this will happen soon?
Radiomaster Zorro comes with internal ELRS. You can put it into binding mode and then power cycle a receiver 3 times to put that into binding mode - no flashing neccessary.
The whole point of flashing is to keep it up to date with new features and bug fixes etc. However without flashing you miss out on Binding Phrase.
Flashing is super easy.
Do i need module if got boxer and radiomaster rp1 receiver
Not if you get the ELRS version of the boxer. If you get the jp4in1 you will
So are you saying if I have a radio master Zorro updated to ELRS 3.1.1, I can’t flash a BetaFPV nano rx V1? It would seem that’s the case because I can’t get configuration to update the receiver in pass-through, Uart or Wi-Fi.
Both receiver and transmitter need to be on the same version.
What ExpressLRS Transmitter and Receivers are you using?
I'd like to see a ELRS TX Modules comparison... mainly the BetaFPV and Namimno... Do you have clue on that? Thanks for your videos!
What about the two would you like to compare?
I’m using a brand new Zorro with an old Betafpv version 1.0 Nano rx. I updated the Zorro to 3.1.1 and I’ve tried to update the rx as well but it won’t take the update. It tries to access COM 16 and comes back with error “access denied” while using beta flight pass through. I’ve disabled firewalls, updated stm drivers, the rx just won’t flash. I’m going to try a newer rx next. The betaflight nano is something I won from TweetFPV’s live stream a year ago. This is my first dive into ELRS and so far, it’s only been a headache. It took hours just to update the radio to 3.1.1 when I learned I had to update EdgeTX first. It’s a brand new radio!
Updating EdgeTX is more of a Radiomaster problem than an ExpressLRS problem. Update your receivers to 2.5.1 via Wifi, then to 3.1.1. Always do wifi and not Betaflight pass thorough
Can i do long range with happymodel elrs 915 mhz tx module and rx
Absolutely… you will run out of video before radio
@@DarrenAllatt thankyou for the information 😄
"the only time I update is because of a build or crash" ....Does a crash impact the rx? I have a rx that stopped communicating with the tx after a crash and I just assumed it died. Does re-flashing solve the problem?
Sorry I will clarify further… typically after a major crash, my quad goes back to the bench for repairs. Could be anything from a broken part of the frame, smashed camera, busted motor. While it’s on the bench being repaired, I’ll update the firmware.
Crashing on its own doesn’t necessarily impact the RX, or it’s ability to work. If it’s not communicating with the FC it’s likely the solder points are loose flat either the RX or FC side.
@@DarrenAllatt Thanks!!
I own a zorro 4-1 can this be compatible?
You need to add an external Nano TX to use ELRS. There is another version of the Zorro with internal ELRS but it’s not the one you have
@@DarrenAllatt I have the 4-1 version. Can this be complete?
@@55amps You need to buy an ExpressLRS Nano TX Module to add to the back of your Zorro. Your JP4IN1 doesn’t have internal ExpressLRS. There is another version of the Zorro which you don’t have that has internal ExpressLRS
@@DarrenAllatt done ✅ ima get that! Is setting it up easy ? I’m such a noob lucky ik how to bind it regular style.
@@55amps small learning curve. I’ve got plenty of videos on how to do it
I bought a Hglrc rekon but is not connecting to my lite 3
Was it an ELRS version?
What have you done to set it up?
@@DarrenAllatt yes does it it support crsf
@@Ktorome so which Rekon quad did you buy? There are a few
@@DarrenAllatt the rekon 7 elrs
@@Ktorome have you got ExpressLRS working on other aircraft and this isn’t working; or is it your first setting up ExpressLRS all together?
Hey man, I got 2 drones with elrs & on the same controller but one isn’t showing LQ 0:0 instead of say 6:100LQ.. do you know what’s wrong with that specific drone that’s not showing Lq but it’s checked on the osd.
Is the quad that doesn’t show it DJI or Analogue?
And for that quad is “telemetry” turned on in the Configuration tab of BF?
@@DarrenAllatt analogue & telemetry is tuned off! Also just updated all to version 2.4
@@DarrenAllatt thank you so much for replying 🙀🤘🏽🤘🏽
@@adrianau4246 does everything work in the receiver tab?
@@DarrenAllatt yes my controls are responding!
