Express LRS [ELRS] 3.0-RC2 Matek Crossfire to PWM First Flight
Vložit
- čas přidán 13. 08. 2022
- Express LRS 3.0-RC2 provides up to 16 fully proportional channels. When paired with a Crossfire to PWM Converter, Express LRS can now be used for fixed wing configurations requiring more than four proportional channels.
In this video, I have an Express LRS Receiver installed in my Precision Aerobatics XR-61 for a test flight.

Very nice and informative video John. ELRS is a great platform to use. Lots of learning ahead for me. Keep up the good work.
Thanks Bill. Will do.
Good to see you are at the field again John - ELRS is still a little intimidating for me, but videos like this brings me closer to a potential switch/addition, thank you.
Keep watching, there will be a lot more info on ELRS coming to the channel to be sure.
Great video. Loved the transition from the apron to the flight line.
Glad you enjoyed it. Thanks for watching.
Yeah I'm going ers all the way I figured out it would be better in the long run win again great video John glad you got to fly take care
I expect integrated 8ch PWM Rx's. When this CH5 limit is worked out and we have integrated s.bus board that will be checkmate.
John, you are doing us a great service with your coverage of ELRS 3.0! Because of your recent videos, I purchased the Happymodel ExpressLRS 2.4GHz ES24TX Pro Micro TX from Defiance RC, along with 2 receivers and 2 Matek PWM boards. I already have a HobbyEagle A3 Super 4 kit with the programming card so I should be ready for SBUS when the Ch 3 thing is resolved in the final version of ELRS 3.0.
Your Super 4 allows you to change the mode channel. You're good to go with sbus right now. ;) Very good combo you got yourself there.
@@RCVideoReviews Just found out I have the A3S3, not the A3S4. I don't know if it will let me reassign channels like I could with the A3S4. I emailed HobbyEagle to ask the differences between the two.
Super3 doesn't support Ch3 (throttle) out. It requires a signal pin from your sbus rx direct to your ESC so your Rx is the only device managing throttle. This requires your sbus rx to have pwm pins. That's why the the super4 is required. The super3 and most others allow ch5 remapping.
Lol so much for Long range. Love your Videos you are a good teacher..
Thanks 👍
Seems like EVERY time I forget to do a control check (which isn't often) I get bit by some sort of control reversal or other similar issue.🤣🤣 Really drives home the importance of doing a COMPLETE control and C.G. check every flight!
Yes...and I call out my expectations ahead of time too because I've seen guys out there just move all controls up down side to side repeatedly and quickly while saying "yep, looks good" only to take off with reversed ailerons.
In full size aircraft during control systems checks we do whatever we can to visualize the control during movement. Maybe different in big jets, but in smaller planes, that was 100% how I was taught.
ELRS really is the future. 3.0 is great, but whoooboy, can it be difficult to get working. Worth it, for sure, but it could be a deal breaker for those used to simple bind plug pwm RXs...
Small effort to make for the power of this system IMHO.
I have the radio call out my ELRS power levels when they change. That's how I monitor my link status but letting Elrs monitor the link stats and if it is deciding to bump up the power levels quickly, then I worry. Also by hearing it call out the power levels, I can tell where the bad reception areas are. I have this one set of power lines that for some reason was messing with my link. Other power lines were not having any effect. But anyways, that's my set up.
Can you please suggest any links as to how you setup your radio to call out the power levels. Is it just a simple setting or do i have to download something for it?
Nice! Did you get your failsafe configured in the PWM converter board? I found this process to be pretty tricky but definitely necessary. Also if you don't adjust this but are using anything but channel 3 for your throttle the default is 1500, 988 for channel 3. so basically if you don't set the failsafe in the CLI, which is a pain, then hook your throttle up to say channel 1 and turn your radio off it will perform half throttle uncommanded on you which is no bueno...
So this is something you need to be very mindful of with ELRS and PWM at the moment. Whether you are using a converter board or using one of the Matek ELRS-PWM receivers. Which is what I recommend using because at least you can adjust the PWM settings in the wifi mode of the receiver.
Just a PSA for anybody considering ELRS for normal planes. I do think Matek will eventually make their converters a little more convenient and I also think ELRS will eventually set things up so you can change the failsafe and PWM settings via LUA script or something which will be easier. It would be good if both had an option for failsafe of "no pulses" which I think is the safest default output.
It's very cool that plane guys suddenly can have sub 5ms latency and 333hz output to the servos! Not that anybody could tell... But it is nice to know that when you are on ELRS you are on the cutting edge of performance with the very best latency possible. Then you also somehow get limitless range and telemetry on top of this. THEN you factor in the 15 dollar 6 channel PWM receivers and 12 dollar serial out receivers and it seems like just a matter of time before ELRS is the normal. The only issue at the moment is the firmwares and flashing is complicated but I think they might get that figured out, time will tell.
Also wanted to add I have maybe 2 hours of air-time on ELRS 3.0.0-RC1 with no glitches so I think I might be in the clear for weird glitching issues, link seems solid. ACCST would do weird glitching for me, at least on 1.x firmware, maybe 2-3 times per hour in the air it would disconnect for 1-3 seconds then reconnect. Spektrum was better about this but would occasionally just failsafe within line of sight then lawndart into the ground. Futaba FASST has never done a weird glitch for me and I probably have 200+ hours of air time with it.
Nice info. Thanks.
I just started using TSB crossfire on my planes. Is there really any advantage to going to ELRS ?
RX's are half the price. TX's are half the price. The binding phrase is priceless. It supports bluetooth joystick. Supports loan model feature. Opensource = relatively rapid development cycle. Internal ELRS showing up from multiple manufacturers. Configurable packet rate (Crossfire has 50/100/150 auto selected, ELRS goes up to 500 with a new low latency mode and a new diversity mode. Telemetry ratio is configurable. That's just off the top of my head.
Do you have a video that shows how your getting the ESC telemetry (current) into this ELRS receiver ? Which ESC are you using ?
Might be a stupid question, but I’m just learning about elrs, and considering it for my airplanes. I’m curious to know if your radio is a 4 in 1 with a elrs module, or does it have elrs built in? I see two antennas on your transmitter, but not sure if that means anything. I’ve been considering getting a radiomaster tx16s. The more I read about them, the more I’m starting to like them.
In this video, it was a 4in1 with External ELRS--hence 2 antennas. My current radio is just ELRS.
What is the ADVANTAGE of Express LRS for LOS fixed wing? I'm missing how this is better than the FrSky S8R with MLVSS telemetry.
If you flight not only LOS, a single module and protocol for everything between from a tiny whoop to a long range fixed wing it’s convenient
@@EnglishTurbines increase range while flying LOS is probably not the main driver
RX's are half the price. TX's are half the price. The binding phrase is priceless. It supports bluetooth joystick. Supports loan model feature. Opensource = relatively rapid development cycle.

Telemetry ratio is configurable. FrSky sensors are not built-in and usually cost $10-$20 each. The converter board has vbat, current, AND GPS (which I didn't use) built-in and the entire board is $10.
That's just off the top of my head.
"ELRS is still rather crude in comparison but it's getting better...🤔😏🇬🇧"
I have to disagree. I think ELRS is actually better than Crossfire in comparison:
MUCH higher packet rates
MUCH better software - TBS AgentX and AgentM both are buggy as $^#! - Way over complicated and unreliable where ELRS Configurator is simple, elegant, and quick. When the hardware is configured properly it works well.
TBS Agent Lite LUA - Exceptional, but I know the guy who wrote it, so I'm not surprised.
ELRS LUA - WIP but fully functional, fully usable and improving daily. PS TBS Agent Lite can be used to configure ELRS.
LORA - Superior for range.
ELRS - Selectable packet rates, selectable telemetry ratios, selectable PWM output options (8/12/16) to preserve bandwidth and increase range.
ELRS - Selectable switch modes to preserve bandwidth and increase range.
ELRS - Selectable power levels and switch assignable.
ELRS - Binding phase is superb
ELRS - Bluetooth joystick
ELRS - Model loan feature
ELRS - Model ID can be used for templates/profiles
ELRS - WiFi addressable RX and TX
ELRS has a literal army of developers and I believe they've surpassed Crossfire in most meaningful ways at this point with the solitary exception of no native sbus. IMHO Crossfire is the one which is rather crude by comparison at this point.
Google elrs 868 Might surprise you.
The features I referenced above aren't coming out. They're out right now.
I run an PA Addiction on eLRS 2.5 w/Matek 10 ch board (8 channel) and a Happy Model EP1 rx. I use 250 hz locked at 100 MW and am nowhere close to -90db at the max visual range (and I mean really far away). You should have much better range and I wonder if something’s up with the 3.0 firmware. Have you tried 2.5?
I want the proportional channels 3.0 offers. I've used < 3.0 on quads. My antenna orientation was off too. I'll adjust that for next time.
@@RCVideoReviews I’m eagerly awaiting 3.0 as well. I normally run Crossfire on my planes but had to give eLRS a try. With 3.0 I’ll likely be moving more of them over. Keep these videos coming. Thanks!
is there any reason not to use dupont connectors for RX or vTX signal wires? can vibrations cause errors?
Is there a better type of connector for sensitive signal wires?
Not all RXs have holes. There are thousands of quads in the air with soldered Rxs. They operate on voltage and aren't sensitive to vibrations. The solder joint could be, but that's true of every solder joint on the entire craft.
Your Rssi being a little on the low end may be due to the carbon in this model. Perhaps relocating the antenna may improve the signal strength.
Or getting the orientation right. The antennas is actually sitting on the other side of fuselage shrink wrap. Location wasn't the problem, orientation between it and the radio being out 90 degrees didn't help. czcams.com/users/shortsQ3efCA1nRZY?feature=share
Hi all, can you tell me the make and model of the external RF TX Module being used in the video please?
It's a Happy Model Pro 2.4 ELRS TX. They're widely available (at least in U.S.)
Ok, so where do I find the Widgets to give them a try? Thanks!
You found it already...
Using Fr-sky S-Bus I believe you use channel 5 for the throttle. Sorry, that's on the Hobby Eagle A3 Super 4.
Yes, you're thinking of the Super 4, and don't confuse channels with output pins. The Super 4 sends Ch3 out on Output 5. sbus is sbus. Channels on Edge/OpenTX are defined in the Mixer, not the protocol.
To be fair the PA planes have alot of carbon fibre which can block signal so I have an external antenna extension on my Katana so impressive that you kept 80% link 👍
I also found out after the fact I had orientation out by 90 degrees (smh)
@@RCVideoReviews which way do you like to position your rx antenna? Vertically?
It doesn't matter with a single antenna. What matters is the air antenna and ground antenna predominantly share the same orientation. In this case I had the air antenna aligned vertically and the ground antenna aligned horizontally which was a mistake. The following week on another plane, I had them both aligned the same direction and the results were better. This week, I've acquired diversity Rx's, so I'll be using diverse antennas on all of my nicer planes. With dual antenna setups I always set them up 90 degrees apart.
@@RCVideoReviews Thank you. Your content is fantastic.
Is there any data on how ELRS receivers perform on gas planes with electronic ignitions?
I'm not aware of any and I have no first hand experience with gas planes, so I can't offer a point of view.
I’m confused as to how your getting the pack voltage? The receiver is limited to 9V so the pack cannot e directly connected to the receiver.
You're not watching all of my videos....
czcams.com/video/RzZcbZ6N450/video.html
czcams.com/video/F4U9jDE4e2M/video.html
The receiver is limited to 5v.
With planes what output power do you set 250mW? And with what refresh rate?
I always just max out the output power using dynamic and 333hz 16/2 gives me 16 proportional channels at 166hz which is faster than just about anything on the market.
HELLO THERE, I TRIED TO UPDATE MY ELRS-R24-D MATEK RECEIVER TO ELRS V3.0.RC2 AND I UPDATED ALSO MY BETAFPV MODULE . THE RECEIVER IS BOUND TO THE TX SINCE I HAVE TELEMETRY HOWEVER I HAVE NO PWM SIGNAL COMING OUT from THE MATEK CRSF-PWM CONVERTER,(CRSF-PWM-6). CAN YOU PLEASE HELP? THANKS
Make sure you have tx and rx swapped. Tx on one goes to rx on the other.
if you never want to failsafe you could reduce packet rate and go to 10mw. If you want to have best resolution you could raise the packet rate but definitely want increase mw to 100mw or more
I fly pretty much every plane I have right now on ELRS using 333hz 16/2 or 333hz 8ch with dynamic power set to 1000mw. Upon review of my log data, it's rare power ever exceeds 25mw. Occasionally I'll see a hit at 50mw. This is all LOS of course.
Please post another video pushing that plane to the limit....
I don't really have the skills to find the limit of this plane.
