Read all about it here - www.expresslrs.org/
Links to the BetaFPV modules I have here: bit.ly/3imPJ0a (check local BetaFPV stockists too)
It is worth mentioning that this system may not be legal to fly in many places as their isn't the necessary certification - yet. Vendors like TBS have to work to ensure compliance with local legislation and be able to demonstrate that. Examples of the kinds of paperwork are www.team-blacksheep.com/doc_c... and www.team-blacksheep.com/tbs-c.... Without these documents it is illegal to sell and use in many places. I know for many, this aspect isn't exciting or of interest but you need to be aware of this.

After seeing the range on a friends video it seems only VTX range is the limitation. Exciting progress.

Getting back into fpv after a few years.. now this is cool

@BryonGaskin 2 года назад

Great video. I'm glad to see other options coming, especially for the 915 mhz range. Right now not for me, BUT if more of MFGs start to release these on AIOs or include them as an option as a BNF (yeah probably going to happen on the quad side first as BNF rigs (any type of BNF) is really limited. For example if I were to go buy a REKON 5 and as a BNF and I had the option to pick EXPRESSLRS, I'd more tempted to look into it.) Right now, even with the configurator it seems pretty complex (although probably a better option than trying to get FRSKY xxx to run the same protocol as the 5 in 1 multi module on the Jumper T18 LOL). It is great to see the work that people have done to reverse engineer it then even better that some of more experienced people like yourself who are pressure testing it and finding the bugs and doing videos like this.

@Painless360 2 года назад

I am sure that over the next few months the whole ELRS ecosystem will get a lot more polished and easier to setup and use. The challenge for the ELRS team is the huge amount of 3rd party hardware and use cases they need to support - something most closed-source vendors don't have to worry about. One of the major problems for the project long term is nothing to do with the technology but the legality. Declaration of Conformity and other legal paperwork is needed to be able to sell and use this stuff in many parts of the world.. Happy flying!

I think it's important to make the distinction between the issues you had as a BetaFPV hardware problem rather than an ExpressLRS problem.

Great stuff Lee ! I'm thinking this could be nice for fixedwing too ... Do you know of any receivers that might work with ELRS ?

There are lots coming out at the moment. BetaFPV, Matek and others make them..

@Retset 2 года назад

I knew nothing about it so many thanks Lee. I already have a crossfire module in my TX16S s o see no need to be an early adopter. However, this looks very intriguing for the future of our hobby.

@junglistfpv8553 2 года назад

Hi Lee, just got my elrs gear as well can't wait to try it out! A few videos ago I asked you if the normal DJI camera would fit in the Tadpole HD and you said it would, but after ordering I have found out that (probably due to armattan's tight tolerances!) that it won't fit. Any suggestions on how to create an extra milimeter of space? You have lots of experience with this stuff so I hope you can help me out! Currently down for the count :(

@anthonystownsend 2 года назад

You can squeeze it in, it won't damage the camera at all. Joshua Bardwell mentioned it in a Livestream not long ago, that's what the majority of frame designers are doing instead of making a seperate frame for the 20mm DJI air unit camera.

@licensetodrive9930 2 года назад

The more I watch / read about ExpressLRS the more I'm tempted to buy a TX module to try out the RX's that Happymodel & BetaFPV sent to me so I can make folding TPU holders to put on Thingiverse (Happymodel done, BetaFPV 2.4G RX next). But then I remember I have Crossfire which is virtually plug & play :)

@Painless360 2 года назад

As a Crossfire pilot I know what you mean. It just works and is something I can trust, even on the expensive models.. Happy flying!

@MCsCreations 2 года назад

Well... It's not that expensive, dude. Maybe when you got some money left... Test it. 😊

@anthonystownsend 2 года назад

Do it man, everyone keeps saying "oh flashing ExpressLRS is difficult' is ridiculous, it's no harder than flashing betaflight.

@mclay2038 2 года назад

You mentioned that ELRS connects to a rx tx uart. Do you know if there are plans for its use with ppm or sbus? Thanks.

@mgtschida 2 года назад

There's a PR for adding CRSF inversion so you can use an SBUS pad, but not output SBUS. There's also at least one person fiddling with an ELRS PWM board for wings and such but that's still early on.

@HaveFaithInGod 2 года назад

I still don't know what it is. Yeah I'm 73 but I fly. Is it a new protocol something like crossfire. Does it give longer range to quads? I have a Jumper T Lite that has a add on module bay on the back but which module shoud I get ? Aren't there different sizes as well as freqs? Would it work on my Deviation based Jumper T8SG Plus radio? It too has a module bay. Is there a VERY basic video around that truly explains what this mysterious (to me) Express LRS actually is from the ground up that won't expect me to know so much in advance that watching a video like this goes completely over my head. I guess I'm in the minority of the hobbiests or maybe you are in the elite of the hobby. I applaud what you know but it meant nothing to me. Thanks for your efforts and I'm sure it must have been helpful to some or even most. IDK

@Painless360 2 года назад

Sorry to hear that you found the content of the video too complex. ELRS is a new protocol that can be be used just like others available that you are familiar with. The main differences is that this one is not 'owned' by a radio manufacturer. Happy flying!

@eriktoussaint 2 года назад

Hi Lee, why would one want to use ELRS? What is it for? What is the advantage?

@Painless360 2 года назад

Not tied to any one vendor. Will work with lots of legacy hardware as well as the new stuff coming out. Impressive range and full telemetry link for one of the lowest prices for this type of kit. See all of these covered in the video. The only questions are about the complience of the system with local legislation... happy flying

@mrmagoo600 Год назад

Sounds troublesome! Has it gotten better since the date of this video do you think? Considering getting the Tx16s and which internal tx system to get it with and elrs being one of the options built in or the 4in1 looking into info about each. Currently using tracer but considering ELRS only it doesn’t seem to be a very straight forward system.

@Painless360 Год назад

ExpressLRS has matured a lot since this video was made. We are now on V3.x and it just keeps improving. The hardware options for ELRS have improved out of all recognition too with vendors like RadioMaster really working closely with the project to deliver some solid hardware. See my other, more recent, videos on ELRS..

ELRS isn't specfic for FPV. The benefits remain the same for LOS. Happy flying

@maxun1 2 года назад

Lee, Powell just put a video out about the legal issue of using ELRS.

@Painless360 2 года назад

Good for him, closed source vendors like TBS put a lot of effort into compliance with local laws and legislation i.e. www.team-blacksheep.com/doc_ce/id:2028

@mgtschida 2 года назад

I think it's a fair point to alert people to the legality issue. I think it's a little disingenuous by some though because we should probably talk about the legality of the hobby overall. Anyone transmitting video in the US? Over 25mW in UK? Not using an LBT firmware in EU? Using D8 in EU? And yet dragging ELRS through the mud? Like I said...fair point to say the devices/firmware are not compliant.

@mgtschida 2 года назад

Happy model has already released a board with ELRS on board. The SPI-based receivers are hitched to Betaflight 4.3 which is problematic, but there's at least one that's on the board as a serial RX.

@GoatZilla 2 года назад

All this hardware being fully Open Source means it has a very long life ahead of it. You could repurpose it for other applications if you wind up no longer using it strictly for RC models.

@@Painless360 IMHO, _that_ should have been a given from Day1 but I was more concerned about the apparently _forced_ requirement of sacrificing one channel for AUX1/Arming the vehicle. I stopped flying ( just don't have the nerve dealing with regulations sucking the joy out of a hobby ) and went back to ground vehicles so I _may_ not even be the target audience but enforcing a concept onto _everyone_ is kinda backwards from what I'd expect to see from a new system 🤔

@user-th6se5xw1v 2 года назад

I see a lot of people jumping on as its the new hotness with high refreshrates etc, but then getting burned with nothing but troubles. Problem is, it isn't consumer ready at all. People complained about how flakey the TBS ecosystem can be in certain circumstances, but it is orders of magnitude more robust than ELRS. This will of course change in time as the ELRS core becomes more mature and stable, and the focus moves to all the end-user comforts and code to catch all the edge-cases (there are lots!) with flashing firmware and binding etc.

@anthonystownsend 2 года назад

The only place people have been having issues is when a) using FrSky R9 hardware and b) not updating the firmware for bug fixes. To say that the TBS ecosystem is more robust is false, LoRa is more widely used The reason why some many people are switching is because of the problems and hardware failures with TBS lately. Not to mention the 1/3rd of the price of a TBS nano receiver. Anyone who brings up that lack of customer support and hardware failures as a reason to dismiss ExpressLRS just doesn't understand the project.

@user-th6se5xw1v 2 года назад

@@anthonystownsend I'm not talking about the robustness of RF modulation, but the software/patching ecosystem and firmware bugs. There are many reported issues with ELRS beyond what you have listed. Check the github issues page, check the facebook group, check discord. There are many varied problems being reported all the time. ELRS will only get better, and is certainly a viable RF link right now if you're prepared to overcome teething problems, but if you just want to fly and not do any tinkering there are better options as of right now.
