Intro to Express LRS • For ELRS Novices

[@bulufish8208]

Thank you the only way to keep this hobby alive is bringing in newbies. And making it easy for them to stay.

Absolutely, Ive been using analogue for years and its hard to find any ELRS beginners guide anywhere. If there are any, I cant understand the jargon and they are normally rushed. This video is very helpful mate for sure.

[@barnygooseegg5035]

Haha. I am a total newbie to this format, and was really excited to learn about this new tech. I have been flying RC since single channel escapements (you may be too young to even know that term). My dad bought me my first radio, which was literally the very first commercially available 'digital proportional" radio by Kraft in southern California 1970. I have been flying ever since. The funniest moment for me was, after you went over and over about how you wanted newbies to understand this stuff, the modules, the programming, the firmware, etc, and you were talking about flashing new firmware to the transmitter module, scrolling down your web interface, got to UART inverted and said "you can select that if you want", and then blew past it. WHAT THE HELL IS UART?!?! lol Anyhow, nice video! Thanks for the info!

13:21 Was idly listening from my office desk in my sign shop as an RC Newbie looking to outfit my FMS Fox 3000. Your first couple of lines was spot on! People in most help videos are speaking english but the nature of the craft has so many abbreviations, all a newbie can hope for is knowledge obtained by osmosis. FPV, ELRS, BNF, PWM, FJB, the list is endless. When I discovered people fly long range on auto pilot and use FPV I was thrilled. My heart started pounding as I was alerted to the reality that me, a professional power Mac user can join in the fun without using a windows platform, which is harder to me than flying without AS3X and Safe. ExpressLRS-Configurator-1.5.5.dmg had me from hello! Currently, I'm all Spektrum but I will be buying all my gear through your links because your video made my day!

@@RCVideoReviews I’ve been hearing about ELRS and all I know about it is that it is a long range radio control system for drones and since I only fly heli I never look into to it But after watching your video! Now I am curious

[@RCVideoReviews]

It's definitely not constrained to long range. Initially that's where they started as those folks are RF enthusiasts; but the LOS capabilities have grown significantly this year and right now I use ELRS on all of my fixed wing LOS planes.

Great to hear! Good luck. Have fun learning ELRS. It's a really nice RF system.

[@mssippijim]

So true about long range...video will go long before control signals. Furthermore, 2 watts would provide little increase above 1, as there is not a linear relationship between power and signal strength. Thanks so much for this video, I've been kind of resisting elrs a bit because I haven't had any range problems, however, it's getting harder and harder to buy certain quads that aren't ELRS.

Excellent job presenting ELRS and its idiosyncrasies. Unfortunately, you've definitely talked me out of ELRS. Last flown rc planes 15yrs ago. Will start flying again as soon as I can print my Pitts. I think I'll start with Flysky IA6X then move on from there. Thanks again.

[@RCVideoReviews]

You're welcome. It's definitely not for everyone and there are simpler options to be sure. What I like so much about ELRS is I can use it in everything: CRSF talks to flight controllers so Betaflight on quads, iNav on FPV fixed wing. It talks to the FBL I like to use so I can use it on helis. And it has PWM output options with telemetry, so I can use it on fixed wing for LOS. On top of that the receivers are fairly cheap.

I am going through your channel videos, it like eating an elephant. I thought you were going pretty fast then I realized I had the speed a 1.5... I used to code a bit back in the 1980s, compiling from a tape could take hours on a big VAX, prior to that you would insert punch cards all night on like a P-11 (before my time).

Small correction, the full sized ranger can go all the way up to 2W! It is more powerful (but it's useless for most people)

[@RCVideoReviews]

Not out of the box and I don't show it because I don't want to be the one responsible for telling everybody how to violate part 15 rules. So it's not a correction. The device allows it, but the manufacturer correctly set it to 1w to comply with the law.

[@FAB1150]

​​@@RCVideoReviewsoh I completely agree on you not showing how to circumvent the law, but it's a selling feature even if they never explicitly say it to not get their product banned. In their website they only say "default 100mW" under RF power output in the product specs of all three for the same reason, lol If it was intentional though I also agree it's not a correction

[@RCVideoReviews]

I've been flying LOS with ELRS for a while now and it's pretty rare to see Tpwr in the logs > 10mw. Every now and then a 50mw burst. 2w is just over the top and really not necessary unless you're doing some seriously long range and then you're going to have trackers, and some serious knowledge on video setups. So I figure at that point, you already know the hack. YT is a great teacher. Sometimes it's just better to leave certain things unsaid.

For anyone shopping for a Ranger module, the biggest one, with the aluminum casing, will shed heat more quickly than the smaller version, that has a plastic casing. Just something to take note of.

[@RCVideoReviews]

I was flying all weekend in Florida. It was 95 degrees outside yesterday. Telemetry on the micro showed RQLY about 95% or higher, TPWR at 25mw 99% of the time with one or two spikes to 50mw. So I had superb LOS radio performance throughout the weekend with a legitimate heat test on the micro. That said, my TPWR was low the whole time. If your use case mandates a higher TPWR, the aluminum case might make sense.

[@Inertia888]

@@RCVideoReviews thank you so much for all these stats, I will put them in my folder, until I have a better idea on the full range and performance of these modules. I am interested in how the 2Watts will handle penetration ( I see you suggest that LoRa is not necessarily aimed at pen, but looking forward to field-testing ) of green leaf canopy. I have not yet put my drone in the air, since I received the module.

[@Inertia888]

Just an update to the thread... (not adding much to what RCVideoReviews already said, just getting back to my original comment) >The Power Output of the RC-Link, that is needed when flying with a Video RX/TX will never be anywhere near what is needed for the Video Link. I Don't fly long-range, so I can't speak to that, but at ELRS-150mW, the RC-Link is way, way, more powerful than my DJI-V2-1200mW. I can' not find a use for the ELRS 2-Watt Power Output, when I am using a Video Link. >If you need the full 2-Watts ELRS RC-Link, then you probably already know a lot more about radio than I do.

[@Ard1400]

Great video! Thanks a lot. I hear from others that when you use 1 watt or higher power you should always use an external power supply. Is that right?

[@RCVideoReviews]

I cannot validate the question. Two points: 1) We're talking about radiated power, not electrical power. I don't believe it's a 1:1 correlation between radiated power and electrical power, but if it were 1:1 then: 2) 1000 milliwatts = 1 watt. W/V=A. So 1w/5v= 0.2a or WORSE: 2000milliwatts = 2 watts. 2w/5v = 0.4a I seriously doubt the pins in the JR bay would struggle *at all* with .4a. And I know the batteries in the Tx should be able to easily handle an incremental half amp. So personally--I doubt an external pack would be required. Finally, Radiomaster did not stipulate in their instructions that an external pack is necessary for 1w of transmit power.

[@Deathwish_fpv]

You have to use this dongle on all elrs receivers or just certain ones

[@RCVideoReviews]

This is a trick question: You don't "have" to use the dongle. You can flash via wifi. All receivers can be flashed with the dongle. I recommend ensuring you have the dongle because on countless occasions I've flashed a receiver using the correct firmware and wound up with a corrupted flash from which the only way to recover was via dongle. This isn't a question of brands, it's a question of what to do if you do everything right, but still get a corrupted flash.

I like the Matek CRSF-PWM-C. It's 10 channels, but has voltage and current. If you can get by with just voltage, the CRSF-PWM-6 is pretty nice.

Hi, do I need a flight controller to use expresslrs?

[@RCVideoReviews]

No. It works with FCs of course, but look at Radiomaster ER series: ER6, ER8, ER4 etc...all straight PWM.

[@CptAwilliamse]

@@RCVideoReviews thank you very much

[@Dog_Botherer]

Is this necessary equipment for rc flight in general or just for long range?

[@RCVideoReviews]

You have to have an RF transmitter and RF receiver. It may as well be this protocol. Can't beat the price, features, or reliability. Nothing else on the market comes close. PS And oh yeah, if you want to fly long range you can do that too. I use this protocol on every line of sight (LOS) plane I have.

[@Dog_Botherer]

@@RCVideoReviews my apologies, I didn't word that question very well. I also assumed that the ranger module was just for extreme range. Is the ranger module a must have for the transmitter to work, or does the transmitter still work without it?

[@RCVideoReviews]

All TX16s come with an RF transmitter. Some are 4in1, some are ELRS. None of them ship absent a transmitter.

[@Dog_Botherer]

@@RCVideoReviews gotcha. Thank you

[@richdabarber]

Can u use the ranger micro in a 4in1 tx16s?

[@RCVideoReviews]

Yes. It works great in the TX16s.

Hey i can not Find any receivers with pwm that have more than 5 channels how van i use erls in my fixed wings that need more?

[@RCVideoReviews]

In the video I showed the crsff-pwm-c converter from Matek. That will give you 10 channels. kzbin.info/www/bejne/gKrQh2prZ7V9fa8 This also works: kzbin.info/www/bejne/pYbGfoCgpbNnq5I I'm hoping we'll see manufacturers produce some 10 or even 16ch pwm rx's this year.

[@emmanuelcheveau4891]

Hi !! - I have same radio - same ranger module - Which baudrate & packet rate you recommend for indoor flying ?

[@RCVideoReviews]

400k. 100hz is more than enough for most people. Since you're flying indoors, have no fear jacking it up to 1000hz if you want as you don't have range concerns.

@@RCVideoReviews Ok thanks I might give the elrs a try. Do you have to upgrade the firmware on both the Rx and module

@@RCVideoReviews Wish there were videos showing this stuff for airplane guys. It's always quad stuff. What are those Xt60 connectors used on that board and why two There's no videos on KZbin showing how to use ELRS for an airplane

The Rx and Tx have to have the same major revision #. So 3.x on Tx and 3.x on Rx. We covered this in the video. Didn't you see it?

I am a subscribed. If i do not do fpv, and only flying watching my small foam planes at the local park or a club , do i need ELRS? what do i lose for not using ELRS in my case? tks

[@RCVideoReviews]

I use ELRS in all of my LOS models. Cost effective, locked on RF, binding phrases, bi-directional CRSF, onboard vbat, plenty of form factors, packet rates to 166hz for 16ch, 333hz for 8ch, opensource development by hobbyists who know what they're doing. To me, this question needs to be flipped: Why on earth would you use anything but ELRS?

[@alexherrera3918]

@@RCVideoReviews Well put, i only recognize about 1% on the names you listed in your response but it seems that there are many things i am missing from not using ELRS, i will continue watching your videos to learn about it. thanks for your response.

@@RCVideoReviews What good are more channels if there aren't switches/pots on the Xmitter or the ability to add them?

You should probably start watching my TX16s videos and do a little research. The TX16s can support 32 channels.

@@RCVideoReviews Well, I've watched both the videos and I'm sure I can replicate what you did, I just don't know why. Are those tiny boards really the only receivers onboard?

What if u fly in the city how much power can someone get? Cus I live in big city .

[@RCVideoReviews]

Many ELRS TXs can go up to 1w of radiated power. Check the specs of the TX you're interested in. Some have been known to go as high as 2w.

The only way to know the answer is to go test it. This is 2.4ghz and subject to the same laws of physics as all other RF.
