Nice feature on ExpressLRS Nick! Thanks for taking the time to do a bit of research before making your video, all of the info was spot on :) Well done!

[@NickBurnsFPV]

I stay in my lane. You and others have done all sort of leg work and I don't have near the level of understanding you all have. They need to come watch and talk to you and the expresslrs team. Thank you for doing all that you do. I hope you received a bump in traffic. I think ExpressLRS is going to be a world wide hit.

[@MrFadjule]

So how much testing has been done on 915 mhz? I saw lots about the 2.4 system, how different is this?

[@ronbo422]

Wezley, you enabler, you!! I flashed my R9M/R9MM to ELRS successfully. :)

[@itsme-fr5fr]

I think its awesome when people do things to drive the hobby forward and make things cheaper so more people have the opportunity to get into this hobby. I just got crossfire so ill definitely wait but be looking 4 that 2.4ghz though. Thanks to happymodel and you too nick, i had no idea this was in the works but it sounds awesome

[@Tokyo_Dom]

FYI the 30+ km range test was with the 2.4ghz ExpressLRS system, on only 100mw! The 900mhz version should go further, on the same power setting... and the HM module can go up to 1W (hence that heatsink)!

[@NickBurnsFPV]

I am most excited to see the whoop board with onboard ExpressLRS, should solve the spi rx issues we have been seeing for years. And the lower latency could help fly whoops even faster.

Hi Nick can you tell me what RF power output levels in mW from highest to lowest does the Happymodel ES900TX let you choose from?

[@bengmo64]

It would be cool to have a whoop board with a receiver that doesn't suck if it's not too heavy. I don't like to go much over 20g

[@NickBurnsFPV]

Yes it would. If they can manage to continue to do an AIO we should be able to stay under 20grams. I don't expect the 2.4ghz to require the same antenna, which would also help keep the weight down.

[@jackhoughton8868]

Hay Nick, any advice on a drone suitable for indoor flight and low wind flight outside. I’ve seen your review on the mobula 6 and I really like the look of it. Have any new drones come out since then that you would recommend over the Mobula?

[@NickBurnsFPV]

At this time I am still recommending the mobula 6 for a balance between cost and performance. The AE65, has a better canopy and camera, but costs more and has a new GNB27 battery connector, which is better than the ph2.0 connector we have been using but if someone has a bunch of PH2.0 batteries that connector can be a barrier. This is the AE65 bit.ly/3dvdNKl

[@jackhoughton8868]

@@NickBurnsFPV thanks Nick. Final question sorry, Is there a big difference between the 2 in terms of flight time that could justify me spending the extra money?

[@NickBurnsFPV]

@@jackhoughton8868 The flight time difference between those two is minimal, but down the road the mobula 6 will need a new battery led as they break down, the gnb27 connector should continue to work well for a substantial period of time. For better whoop flight time I suggest getting a mobula 7 frame and 40mm props, this will allow for bigger batteries and 40mm props are more effecient. Or you can buy a moblite7, but it has an exposed main board, which could be covered with some foam tape or something to protect it.

[@pirateradioFPV]

Awesome but EU needs 868mhz ..the R9 can be flashed to both, is this the same?

[@wdavie27]

Nick Burns do you need to add software or files to your sd card for your radio to run this ,, im using the jumper T12 with the 4 in 1 module

[@NickBurnsFPV]

we do need the elrs lua script to manipulate the elrs transmitter and its configuration/features, as well as, potentially binding and activating wifi to update

[@zic2979]

hi Nick, thanks for the newz! Do you know if the ES915RX would bind to my R9M module if I flash it to express lrs?

[@NickBurnsFPV]

Yes, while I don't have r9 hardware to test, from what I have seen in videos and read if we have elrs is ubiquitous.

[@RCOverKill]

I just bought the 915 version, I've used my QX7 before with crossfire, do I need to flash Express LRS firmware to the QX7? I also bought Sharkbyte, all for a new build. I haven't been keeping up for a few months, it sure doesn't take long too fall behind. 🤣

[@NickBurnsFPV]

We don't have to flash the QX7 to make it work with ELRS. We may have to flash the current opentx if we want to use the 500hz packet rate. 500hz packet rate is a more recent opentx feature. We do need the elrs lua script on our radio sd card in the tools/script directory. We will likely need or want to flash the elrs equipment. Most of the elrs equipment has wifi, which turns on after 30 seconds of power. There is also an elrs configurator we need to build the firmware flashing files, we can also flash from the elrs configurator.

[@TitanFPV]

I've thought about picking up some R9 hardware on the cheap, and flashing it. Already run Crossfire though. I think the latency on Express LRS is stupid low though. Nice info. I saw those that Happymodel hardware popping up as well.

[@NickBurnsFPV]

I am very hopeful the 2.4Ghz version will solve whoop board spi range issues, and the low latency will be perceptible for some...

[@DT-gun]

I bet tbs will be taking a look at the code and implementing whatever they can. Trappy won't take this for long. From what I understand they coded it so that chanels 5-8 are set to just a few points instead of 1000-2000 and that's where they're getting a lot of range since it doesn't need to send as many packets in a transmission.

[@flipfpv]

I was just about to buy Tracer but do I need to consider this instead? The reviews on Tracer were already pretty persuasive but what finally made my mind up was watching one of my flying buddies try it for the first time and say, "it's like its reading my mind..." lol

[@NickBurnsFPV]

This should "out perform" other protocols in both range and speed, but the most compelling issue is cost. By all reports tracer is good and support will likely be better.

[@checkm8606]

Is there a eu version bc 915mhz is not allowed here... And how does it compares it to crossfire and tracer?

[@NickBurnsFPV]

At this time I don't know if it can be changed. I see in the radio we can change other settings like packet rate and mw, I suspect there could be a method, but might involve flashing the hardware which defeats the purpose of HM brining this to market. But I will check with them. From my reading and the testing I have watched Expresslrs is faster and has more range at all power levels.

While I don't directly disagree, the LR competition will surely mean more and more development. Both in LR and protocol speed.

If it’s unlimited range, why not ditch the antenna’s for smd chip antenna’s. As a racer it’s less weight with less to break.

[@NickBurnsFPV]

They just might do something with limited range to decrease weight. Personally I want to see what it is like with it on the whoop board, that will tell us the latency and range and possibly antenna limits, if you can get 1km, then I would think that would be plenty for racing.

[@CarbonGlassMan]

Wow. Crossfire for far less money. Better than Crossfire it seems. I've never gone long range. Penetration is what I need most often, but if you can go long range then it means someone like me would never have to worry about falling out of the sky.

[@NickBurnsFPV]

Not only great range but faster response.

[@atmosboy250]

I've been looking to get into long range for a while... This might be what pushes me to try it! P.S.: link to Wezley's video is not working

[@NickBurnsFPV]

Hmm. only Wezley's link isn't working. I am checking from my desktop which does go to his channel. I opted to link to all his videos rather than one specific video as he has several range tests.

I think that one has deviation firmware on it? If so, I am not sure. I would check the deviation wiki and forum.

@@NickBurnsFPV so it only works with open tx? Will check that too, thanks 😇

I'll get it when it's more streamlined

[@NickBurnsFPV]

streamlined in what way? At this time we need to have the elrs script on the sd card /tools directory.

[@VincentFischer]

Mhh the receivers are a bit pricey considering they didn't had to develop the software and the components are like 2$

[@NickBurnsFPV]

Convenience cost I presume. Isn't $2 low, sma connectors, antenna, aluminum heat sink, pcb etc. Maybe those things are $.01 when buying in bulk in china...idk.

[@VincentFischer]

@@NickBurnsFPV I mean only the nano sized receivers which have only a chip and some passive smds on it plus an antenna but cost as much as the transmitter. The Transmitter module price is definitely justifiable. The whole thing reminds me so much of the inkjet printer cartridges paradigm

Long range and low latency for $50?? Why are people so enamored with crossfire?

[@wiebel1991]

because crossfire is already 6 years on the market. elrs around 1.5 years? And just got serious recently because you can get off the shelf hardware instead of hacking it together.

I'm so surprised that you're interested in this, your the micro guy not long range guy. I really don't see what your use scenario might be.

[@housinit]

Less latency, more locked in feel, and more confidence that you won't failsafe. Tons of people use Crossfire for short range cuz its fast and reliable. If ExpeessLRS is faster and just as reliable, its what people are looking for. Especially people racing and flying proximity.

[@NickBurnsFPV]

Faster control link, this gives possibly a perceptible "connected" feel to our flying. And with it coming on a whoop board in the 2.4Ghz format would solve the spi range issues we have seen for years.

@@NickBurnsFPV Should be no problem as long they provide the customers with the right antennas... The code for 868 Mhz frequency is already there. But since the bandwidth for this is quite small in Europe, I am waiting more on the 2.4Ghz model design.
