*Notice: Please Read* ... 6 months ago, I flew this ELRS quad, the Crux35 SPI. I was blown away at the range (1+ mile) and penetration that could be achieved an SPI ELRS receiver, and I still fly that quad now as it's one of my favorites. I thought for sure that this would be the future of whoops and micros. But as the months have gone by, I have watched the constant firmware updates by the BF team to address ELRS issues. As much of a fan as I have been of SPI ELRS for getting us away from god-awful FrSky and FlySky SPI receivers, I was wondering how the issues with the updates were going to play out. Today one of the ELRS developers Bryan Mayland stated that "SPI hardware should not be considered" in his opinion. And that "ExpressLRS 2.x works fine, but when 3.0 RC starts in a couple weeks, SPI RX will not work at all due to changes in the over-the-air formatting... SPI hardware is already obsolete in the eyes of the development team as that information should be known before making your next whoop." That was sad for me to hear today but now it is understandable why. Just be aware of this before buying a Crux35 ELRS SPI today. It does have the uart fully broken out to solder an external receiver, so I think it's still a good buy. But SPI ELRS is basically dead. Going forward, it seems the plan is to have completely dedicated hardware over uart on the flight controllers, so that there is no mess of BF ELRS SPI implementation vs. new versions.
Im sorry but i dont quite get this, will i be fine buying this now if i already have a elrs transmitter, f.e. the Literadio 2SE, or am i running into a risk of not being able to connect them due to software version diffrences?
That Express LRS, I can't believe that it has an onboard SPI receiver and gets such great range, especially at 100MW. That LQ was nuts! Nicely done John!
Some of you may ask why it says LQ 7:100 when I stated it's doing 250hz @ 100mw. The Tango 2 currently cannot give me any more than 250hz maximum... BUT the module *was* set and bound at 500hz. That's because I didn't realize The Tango 2 wasn't able to do more than 500hz and forgot to rebind before running this test. Still, it doesn't harm the result expressed here.
Thanks - yeah, taking a 3” quad like this that far out is crazy. But it’s one of the few ELRS SPI boards around at the moment - and the weight profile gives plenty of battery to go out a mile and come back easily! With Insta360 go2 on board. It’s all in all a really impressive build. Was just perfect to give this a test run.
@@gbro8822 Ahh man I appreciate that, but really I am still learning every day as I go. 👍 I just try to share what I think I'm doing right and hope it's all good! Lol! You'll probably see posts from me before christmas but otherwise thank you and you too!
First off I just want to say thank you so much for making this, and I really have begun to appreciate your content. You are an awesome help in making information available so that I can have an easier time making that final choice on which products to buy. Also I do have a question, I will be getting the (Betafpv ELRS 2.4ghz Nano TX module) for my betafpv literadio pro 3. Is there anything that I would need to know before buying that and the crux 3.5 and using it with that Betafpv ELRS 2.4ghz Nano tx module?
Hey there, just getting to replying to comments, sorry for the late response. Thank you so much, I really appreciate knowing that my videos have been a great help. Nothing comes to mind that I can think of that you would need to know specifically about having a betafpv ELRS 2.4ghz nano tx module with respect to the crux35 ELRS. The only thing I would warn is that you should upgrade the crux35 to the latest version of betaflight 4.3.1 when you get it, and, to make things simple, make sure your betafpv module is just on the latest ELRS 2.x firmware. This quad can't bind to ELRS 3.0 without some extra technical steps at the moment.
It wasn't your intention but your range also showed me that the 300mW vtx is adequate for the job for slightly long range flying. The big boy long rangers keep advertising 800mW
hi John and congratulations for your videos! I have the crux35 too and I find it a great drone. I have only few problems with the tuning and it would be nice if in your next review you also talk about the Betaflight settings. I have some vibes on the low throttle, especially with the wind, and also some vibes (like if I have an excess p gain) in the fast movements like split-s-. Even in the filters part there are some values a bit high in my opinion. Thanks in advance!
Thanks Luca! I've not made any changes to the tune yet, really what I would like to do is wait until until betaflight 4.3 is finalized before trying to tweak much. It's coming pretty soon! Next week is release candidate 1.
Yea the tune was bad if you ask me, very jittery, but just up the d using the slider (not the values) in betafligh to about 1.2 from the stock level that seems to solve the oscillations.
I’ll be making more videos on ELRS in the future, and this is a great suggestion - exactly what I have planned actually. Right now I’m running ELRS 1.0 and 2.0 was just released. I’ll be updating everything to 2.0 very soon! 👍 thank you!
@@JohnCuppi I’m running 1.2.1 on my x-lite. I tried updating to 2.1 and 2.2 but the lua is not working on my x-lite for some reason. I’m stuck with 1.2.1 for now I guess. Thanks
Hz is the data packet rate. Higher packet rates mean lower latency. 250hz is what immersionrc ghost runs on. ExpressLRS can run an even faster packet rate at 500hz. Unless you’re doing extreme long range you want to run the highest packet rate you can. And 1 mile in an open field is effectively almost nothing to ExpressLRS which isn’t surprising at all - but that the SPI implementation works so well is fantastic to know. Battery life or vtx will be a problem with this drone before the SPI receiver EVER hinders it.
Love ELRS and great video! I saw that you have sky zone goggles. I have the 04x goggles and still having all of the reported problems with them. What firmware version are you on for the goggles and the steady view receiver? And what antennas are you running?
Hey Chrys, thanks! Sorry to hear that about the Skyzones. I am running 2.3 beta firmware, Steadyview receiver 20210422 v2.1 hardware revision. My antennas in this video are the lumenier double axii 2 long range and a menacerc patch antenna. This flight was just conducted in diversity mode. Lately some of the SkyZone group posters have been posting a different problem that I've never seen before, bad reception even /with/ a rapidfire module and no matter what mode they're in. As if there's something wrong with a recent batch of the goggles themselves. Hoping that's not the case. Are yours bad even in diversity mode too?
@@JohnCuppi my goggles were purchased a year ago. I have two modules. One is hardware version v1.2 and the other is v2.1. Daniel with SKYZONE said that this combo would have no issues. I am also on firmware 2.3 official. It's not bad, but definitely has a lot of room for improvement. I fly mix and diversity but prefer mix mode. They are awesome goggles, just wish they could get this sorted out... Had these for a year and still struggling with them.
@@CXBFPV I would just get a rapidfire module. It’s direct fit and fully compatible. Just need to buy a cover/door. Mix mode works well on the majority of models that I fly on steadyview but on some it’s catastrophically bad. It comes down to the mixer not working well. Skyzone has another new module coming out with 3 different mix modes, called the steadyview X. I think the problem is that there is no one-size-fits all mixer. They make a change and it does a better mix for one cam+vtx type and breaks another. The new module will also feature a screen. Unfortunately they said this requires an entire new module to do which is a huge bummer. 😞
Yup, here you go! www.aliexpress.com/item/3256803251782697.html and the file to 3D print one is also available for free as well. Some very cool crux35 prints on thingieverse too: www.thingiverse.com/search?q=crux35&type=things&sort=relevant&page=1
excellent video, thanks! I have the same quad and I have a question: what's the PID Loop Frequency you're using? 4kHz? with the default value, I had a CPU load of over 60%. but I'm running ELRS at 500Hz, maybe that's why? what are you running? thanks!
betaflight 4.3 and 8k/4k using dshot300, I have a CPU load of 12%. my expresslrs module was set to 500hz but the tango2 itself will only process 250hz for your control. I do not think the ELRS is what is causing the high CPU load. What was your default value set and what bf version was yours running?
@@pgabrieli Sorry -- I just rechecked and I accidentally gave you the number for port utilization. CPU load for me is actually only 12%. So I'm baffled as to why the CPU load would be so high for you. I even have the accelerometer turned on mine, which tends to use a little extra CPU. You can disable expresslrs to see if that fixes it but on the board it's set to 500hz for me, I have never rebound it and set it to 250hz yet. Try flashing the newest btfl 4.3, mine is running firmware released on: Oct 11 2021 so it's not RC1.
Great video and review of the SPI Elrs John 👍👍. I only have one quad with the ELRS on it right now and it is so enjoyable to fly. I fully agree with you on the FrSky spi receivers. One quad will do just fine like my original Crux3 and others fail safe randomly. I'm just going to convert my spi boards over to external Elrs receivers once I figure out how to do that. My Crux3 will be one of the first and a little Cine8 will be second. Moving forward I'm only going to buy boards or quads with Elrs. That Crux35 I think will be my next quad purchase.
Thanks for the compliments! I think almost everyone is tired of FrSky SPI receivers and we definitely need to move on -- but until now I don't think there's been a viable replacement. For a while there was at least the redpine protocol but I think that was too complex. There is one bummer -- the requirement at the moment to only use betaflight 4.3, when so many great tunes out there are for lower versions. But, everyone has to upgrade eventually, right? I'm also hoping Emuflight will add ELRS SPI support if they haven't already, that would be a huge help. How did you like the Cine8 by the way? I never got around to building it.
@@JohnCuppi the cine8 is on the way and hope to have it by Christmas, but I know already that it will benefit from an elrs receiver. Will let you know how it goes.
Yes I still love it! I bought a second one on sale! My first one is still going strong. And it's funny you asked about the HD. With the second Crux35 I installed the HDzero system in it. Been testing it out the past couple of days with good results. I can solidly recommend the Crux35.
@@JohnCuppi Nice look FWD to the review on the HD Zero then ! I have the DJI goggles so I am keen on the Cruz35 Air Unit. I just broke my FrSky X lite radio so now I am thinking of buying the DJI radio as I am always going to Fly with the Air Unit systems. Am I doing the right thing ? Not sure about the DJI radio. I don't know !!! lol. Should I buy a radio like yours ?
@@wokbok43 I personally would not recommend the DJI fpv system radio; it isn't 'bad', but I don't think it's worth locking yourself into only flying anything DJI. Also, it is easier to buy something like the crux35 HD with expressLRS and just bind straight to the board like I am in this video. They don't make this in a DJI bind-and-fly form, you would have to solder the caddx air unit to the receiver pads on the board. Not hard, but just something to consider. Tango 2 like I have would be a solid choice, but you can also look into the radiomaster tx16s if you prefer large size radios. 👍 I have DJI FPV goggles as well but I am trying shark byte just to test something new out basically.
No. In fact as an experiment over the last few months I’ve just flown it at 50mw Link quality stays pretty stable. But if you look at where I’m flying it’s typically open spaces like public parks, etc. if I was flying inside an abandoned building I’d go to 250mw.
Also - staying in 50mw conserves my Tango2 battery life significantly. The module I have can passively cool itself with the power set that low, running the fan is not required. (But, you can if you want to.)
@@JohnCuppi great advice. I was flying at 100mw for a while then bumped to 250 thinking it was better. I didn't notice a significant change in battery life but it was warmer. I think I'll lower it back down thanks to your advice. Thanks.
@@JohnCuppi cheers. Iv finally managed to master my ELrs troubles. I can now bind and update over wifi piece of cake. Fly my crux 35 earlier for the first time, and I'm well impressed. But the video quality was terrible, flew about 180m away and it looked like it was going to disappear. But when I got home and plugged into betaflight, I think the vtx was only on 25mw. It's now on 400. So I'll try again tomorrow...👍🏽
@@k1ortia Watch that connector on the vtx as well. In my experience it came off / pops off too easily. I reinforced it with heat shrink, and it hasn’t popped off since. It’s a little weird to get a piece of heat shrink around the corner of that triangle shaped VTX though.
@@JohnCuppi I'm wise to that now brother. Every build I do, or ready to fly kit, gets the hot glue treatment over the connector asap, and iv always conformal coated every single board and vtx, and some FPV camera boards. I was cought out flying in the rain, took me 3minutes to land, the quad was dripping wet but with no issues at all, due to the coating. I shit you not.
on my mobula7 (before i lost it in long grass due to running the battery down and losing video) with frsky and just an emax d8 controller from my tinyhawk 3 kit, i was able to stop it failsafing and falling out of the sky and i did a range test got it to 550 meters out before i turned around due to fighting wind the battery was getting low, but it flew out and back fine, and from inside my dads shed i can fly all around his property over 200m away from inside the metal shed, before i fixed it, it would failsafe and drop as soon as i went outside of the shed and got about 10m away, and that was not doing any hardware fix its just a setting in betaflight and it is so much better and trustworthy flying around, i have a moblite7 coming in the mail soon ill do a range test before and after the fix and make a video because i think it could help a lot of people
Well, this would be a popular video if your results truly work across all models and aren’t hardware based. 550m is an amazing result for frsky SPI whoop. I’ve never ever seen that. Was this with the mobula7 1s or 2s? I took the mobula7 1S ELRS extremely far away: ruclips.net/video/RASKniA6OV8/видео.html
@@JohnCuppi it was the 1s frisky version, such a good little whoop I couldn't believe how much better it flew than the tinyhawk 3 especially outside, it's so fast lol, I killed the tinyhawk 3 by crashing into a puddle so I can't test with that but I have a crux35 coming that I can test it with too, and for the record it did failsafe with very little range when I first got it so I'm sure it wasnt just a good receiver because the tinyhawk was the same problem
@@Cheapzenscripts1 I've never used the Emax Transporter 2 HDzero goggles, but my understanding is that the Emax HDzero goggles use the same standard hardware the HDzero VRX uses. So you should not have any issues with range. HOWEVER -- I see that the two antennas it comes with are cheap, and would strongly recommend switching them out to both Double AXII 2 antennas.
Awesome review and flight my friend. I do agree more companies are going to get on board with micro SPI. As much as I love TBS tracer/crsf. I see them having to step up and compete or move out the way like Fatshark did.
Thanks Chris! Bold comment! 😃 for me I strongly believe that crossfire still has a solid place in the market; and it mainly comes down to quality control of hardware. There’s unfortunately some really horrible ELRS module hardware that users can step in right now, in part because _anyone_ can make it. It’s a blessing and a curse. Some of these companies have been shamed and embarrassed into doing better; because their mistakes can leave lasting marks on the reputation of ELRS. But you are right that they are going to lose out on ELRS for micros if they don’t do something there, and frankly, they may have already lost the battle there as it is. I don’t see any of the main BNF quad manufacturers caring to integrate XF when they can just go with ELRS and profit from it.
Do I need that module to have that range? I just have my ExpressLRS transmitter what if I don’t want to use the module? What’s the range I can get without the module?
@@JohnCuppiHallo. Can you recommend this crux35 for beginners in the FPV world? Is it possible to fly it with 18650 liion battery? Greatings from Germoney...
Thanks! I’m not dumping crossfire either - but, any new micro class quads I can get will be ELRS if possible. Tired of FrSky SPI, it’s time for a change.
300m is not bad for SPI FrSky actually. The problem with it is there’s lack of consistency. I’ve had SPI frsky no good past 50m-100m, made sure the antenna was good etc. but something was just crap. SPI ELRS has been really good.
@JohnCuppi yeah my spi ekrs has been great but most my whoops with built in elrs are on a uart which is nice I can update elrs firmware separate from betaflight
I must be doing something wrong as I can't seem to get this kind of range out of my mobula7 elrs using the happy model es24 TX pro, even at 500. Something ain't right
But your mobula7 1s elrs has one major difference -- it uses a ceramic tower antenna, not a T-antenna like on the crux35! This is a very important distinction that will always result in significantly less range with ELRS. Also if you want 'more range', dial down the packet rate from 500hz to 250hz, you can even go 150hz. The higher the packet rate, the more demand on the link, and range will be decreased. Doing a straight shot on 250hz I was able to get 1.4 miles with mobula7 elrs 1s. ruclips.net/video/RASKniA6OV8/видео.html
@@JohnCuppi Ah ok I guess I didn't see that the crux used a t ant. Yeah I know that the ceramic tower isn't optimized for range but looking at the video you shared, even at 150hz on 500mw I really am not getting that range with my mobula7 like in that video, which I'm thinking might be the module as I also have another elrs whoop and its about the same. Maybe I should try another brand.
Is the betafpv ELRS module running ExpressLRS 2.0 or 1.0? This drone currently ships with betaflight prerelease 4.3 which has ELRS 1.0; but you can update to the newest version of betaflight that includes 2.0.
@@k1ortia If you want to start flying today right now, it's definitely probably easier to just have everything on ELRS 1.0 and then bind. It 'just worked' perfectly for me. But, the way forward is definitely to upgrade betaflight on the Crux35 right now to the very newest betaflight 4.3, which will bring the ExpressLRS integrated receiver up to 2.0. 👍I have not updated my crux35 or happymodel ELRS module to 2.0 yet. Betaflight 4.3 is going to be fully released to the final version any day now, that's when I'll upgrade my stuff. 🙂
@@JohnCuppi Ah, ok. i shall give that a try, only issue i had with the module when messing about with firmwares, was that you loose the use of the Oled,s and the screen. iv just managed to update the Crux 35 to version 2.0. so hopefully ill have something in a bit. Never had this headache with Crossfire
@@k1ortia ELRS development is advancing so rapidly that unfortunately these problems have come up. Since you got the crux35 on the newest betaflight 4.3 and for 2.0 setup there, then I wouldn’t go back to 1.0. Personally I’ve had more than my fair share of problems with crossfire binding issues over the last couple years with the Tango2. 🤷♂️ ELRS still has a higher learning curve at the moment but it’s getting there.
It depends on the battery, but so far for me, all LiHV: 530mah GNB - 4 to 5 minutes (pushing it, but great weight on these!) 660mah GNB - 5 minutes (comfortable 5 minutes) 720mah GNB - 6-7 minutes So my favorite is the 660mah.
I'm not sure about this one actually. I know it's a decent number but I am not sure of the maximum. Are you looking to plan a fly-in event? Flying with some friends?
@@JohnCuppiThanks, I'm actually trying to set up a FPV RC car event for work. i know Digital the max is 8 ai just need to find out if analog will let mw do any more than that.
Happymodel ELRS X1 AIO 4in1 Flight controller. There is a newer version now with ELRS built in on a uart. I am still using this FC though, it has been extremely reliable for me. No issues with it.
Hellomy friend, a question came up related to the output power of the vtx. Does that generate heat on the vtx, right? If so how do one keep it from getting too hot and damaged when not in fly? I know a fan when working with the drone does it, but when in the field, let's say I have to go pick it up and takes me a few minutes. How much time or heat can they resist? Thanks!
Wrong. SPI is a hardware protocol that transports serial data from point to point, it requires three or four signals to achieve MHz bit speeds. The Semtech SX127x(900Mhz)/SX1280(2.4Ghz) LoRa hardware combined with an Espressif or STM32 Processor is the hardware used for ELRS. The SX1276/77/78/79 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using Semtech’s patented LoRaTM modulation technique is how this is being done, the existing non ELRS transceivers use hardware that does NOT have this level of encoding. The SX127x/SX1280 + STM32F4 or Espressif combination has been around for years, using it to transport ExpressLRS protocol was a given since nobody has deep enough pockets to create something better. FYI: Both the SX127x and SX1280 parts can only be connected using SPI, not I²C or UART, the STM32F4 or Espressif talk to the outside interface with serial uart.
not that much farther, but not because of expressLRS being a limit at all! The battery life on this quad wouldn't make it. I was already at 3.6v average voltage by the time I got back.
100% correct on paper! However, just casually ask anyone what they think about “SPI based receivers", the term has become synonymous with “shitty range.” This is only because so many hardware implementations of SPI based FrSky and FlySky receivers are bad. The FrSky D8 protocol being horribly old and slow makes matters even worse. "SPI based receiver" just has a terrible reputation. So, it was refreshing to fly a modern, fast link protocol implemented via SPI receiver that’s built correctly. So it works _exactly_ the way you would expect an external receiver to function, which has virtually NEVER ever been the case for FrSky SPI. I did this video in hopes that anyone who thinks choosing ELRS as SPI would be the same old shitty experience they had in the past with other "SPI receivers", would best reconsider that thought because they'd be missing out. Hence why in conclusion, this result is really not that surprising at all to those who know that.
@@JohnCuppi Alright;) I just didn't like that the impression was left that SPI is a bad standard, people quickly get confused on tech terms. SPI is better than USART in almost any way. Faster, simpler and likely more stable in terms of EMI stability which is always a concern in quads. Express-LRS is clearly the way forward, FrSky has always been a pain. Also given it's open source and open hardware there is going to be a lot innovation coming.
@@haka8702 Well, I'm sorry. I didn't mean to give that impression when I made this. In fact, I was hoping that just the opposite would be cleared up by this video... that SPI is not what we should associate with being the problem. It's just all the bad FrSky and FlySky D8 receivers. I sent this to a few friends of mine before posting it, and they said they would now LOVE to see ELRS as SPI on their whoops instead of FrSky. They did not know that an SPI receiver implementation that could function extremely well like this. ELRS is the way forward clearly as you said, and FrSky SPI receiver implementations will definitely no longer exist for any new products. There is just no reason to keep implementing old inefficient protocols that never had any official support from the manufacturer anyway. That was one of my bullet points for ELRS over FrSky, fully open source and an open hardware spec. There is one small disadvantage to UART vs. SPI receiver that I have run into -- to update the software, a full flight controller firmware update is required. This has been a bit of a pain with updating to expressLRS 2.0 while betaflight is still in 4.3 rc at this time. I will have my second ELRS quad with an SPI receiver arriving tomorrow, the Mobula7 HDzero, I'm sure the range will be excellent and as expected. 👍
This is dumb. You didn't even bother putting any information on the screen as you flew. So we're supposed to be entertained vicariously through your excitement?
@@James-b1l So to answer this question seriously even though it’s rude as hell, I guess you didn’t see the “Picture in Picture” in the lower right hand corner of the flights… that not only printed every statistic available throughout… but also it showcased any break up in the actual analog video feed. So viewers could enjoy the nice HD video but also get to keep an eye on what my actual visual was. You can follow my exact Link quality and dBm numbers from start to end. Battery life. Amp draw. That’s all I had. This was done with no GPS. The flight was approximately a mile out, and a mile back. I don’t know what else you wanted.
@JohnCuppi "multi-media". Just remember that. If there were just a picture with no sound, it would suck. If there were no video and only audio, it would still suck. Both are cool, but add more media for a better follow-along by viewers. You have so many views but very little likes, probably because of what I just explained. It may be rude, I won't argue about that, but at least you know what the problem is now. And frankly, I don't give a rat's south end about how it makes you feel. I don't see anyone else taking the time to give you honest feedback. Your video would suck less with considerably timed flash captions. You're welcome.
This isn't supposed to be a movie dude, it's a simple range test. To inform exactly of what I intended: what kind of range can you get from this drone, and what the video and link quality is like. Then talk about expresslrs. That's what everyone is watching this range test for to see how it did. 300 likes is alright for a video with 13k views by the way, too. 3% to 4% like ratio is considered a "great" ratio by marketing, and this is around 2.3% so it's not bad at all. And I'm not even begging the viewer for likes until the very end of the video, I'd have more if I reminded people in the middle. 57% of viewers are still watching at around the 6 minute mark which is pretty good on a 9 minute video. But I need more "multi media?" Considerably timed flash captions? WHAT? No. I feel like I'm having a conversation with an AI bot. Do you even fly drones? Are you just browsing? How did you even find this video?
@JohnCuppi that's the problem. Communication is a 2-fold event. You can have whatever impression of yourself that you want, you can think you're the best communicator on Earth, but it's up to the receiver whether or not that information has been relayed in digestible format. Out of 13k people, only 300 saw fit give a like. I didn't know you were asking for likes at the end, I didn't make it that far. I found a different video with captions to follow better. Yes. I design, build, and pilot quads. Your video was supposed to be about the receiver range, I was expecting it to be the predicate of your video. I didn't expect it to be about HD visuals and your excitement. You don't have a good read on the audience's pulse. And that's like step 1 of public communication. You can take it personal if you like but I don't know you personally. I'm just telling you what you missed and why I didn't like it.

Some of you may ask why it says LQ 7:100 when I stated it's doing 250hz @ 100mw. The Tango 2 currently cannot give me any more than 250hz maximum... BUT the module *was* set and bound at 500hz. That's because I didn't realize The Tango 2 wasn't able to do more than 500hz and forgot to rebind before running this test. Still, it doesn't harm the result expressed here.
but but the module doesn't care, its still transmitting in 500hz!
@@BrandonBeans Yeah.... actually, *good* point!!! 👌
Wow john good stuff bro . Very impressive. Great range test . Thanks brother
Thanks man, it's a great cheap alternative for a fantastic link.
That was very impressive range John, great in built RX
Game changer for micros in the future I think, as ELRS & hardware gets better all the time. Thanks David.
God stuff!! Glad you’re happy with it
Very happy with expressLRS so far and thanks again for the insta360go2 print!
nice test bro!
id never fly out that far but its nice to know that it can be done !
Thanks - yeah, taking a 3” quad like this that far out is crazy. But it’s one of the few ELRS SPI boards around at the moment - and the weight profile gives plenty of battery to go out a mile and come back easily! With Insta360 go2 on board. It’s all in all a really impressive build. Was just perfect to give this a test run.
Nice experiment. Range is incredible. Technology just amazes me. Just subscribed...really liked your range test.

I learned a lot here. Thanks for the history on SPI receivers
Thank you Ryan! Hoping to get a Crux35 Shark Byte flight up very soon as well. :)
First off I just want to say thank you so much for making this, and I really have begun to appreciate your content. You are an awesome help in making information available so that I can have an easier time making that final choice on which products to buy. Also I do have a question, I will be getting the (Betafpv ELRS 2.4ghz Nano TX module) for my betafpv literadio pro 3. Is there anything that I would need to know before buying that and the crux 3.5 and using it with that Betafpv ELRS 2.4ghz Nano tx module?
Hey there, just getting to replying to comments, sorry for the late response. Thank you so much, I really appreciate knowing that my videos have been a great help. Nothing comes to mind that I can think of that you would need to know specifically about having a betafpv ELRS 2.4ghz nano tx module with respect to the crux35 ELRS. The only thing I would warn is that you should upgrade the crux35 to the latest version of betaflight 4.3.1 when you get it, and, to make things simple, make sure your betafpv module is just on the latest ELRS 2.x firmware. This quad can't bind to ELRS 3.0 without some extra technical steps at the moment.
Nice review John. I am a BIG ELRS Supporter. Love the capability and Love the price (not to mention the size/weight savings).
I’m now a supporter too! I’m going to put ELRS EP2 in my flywoo baby nano 1s ^_^ thanks for stopping by!
@@JohnCuppi Yep, good call...I bought that version and it has been great.
Nice flying John. Thanks.
Thanks rob!
It wasn't your intention but your range also showed me that the 300mW vtx is adequate for the job for slightly long range flying. The big boy long rangers keep advertising 800mW
Subbed! Sick. Didn't know you had a channel. Nice review brother!🤙
Dude thanks for checking it out and subbing!
ELRS is the way to go

Pretty awesome John, will check into it,, thinks for sharing!
Thanks! Have a great holiday.
@@JohnCuppi U 2 as well
hi John and congratulations for your videos! I have the crux35 too and I find it a great drone. I have only few problems with the tuning and it would be nice if in your next review you also talk about the Betaflight settings. I have some vibes on the low throttle, especially with the wind, and also some vibes (like if I have an excess p gain) in the fast movements like split-s-. Even in the filters part there are some values a bit high in my opinion. Thanks in advance!
Thanks Luca! I've not made any changes to the tune yet, really what I would like to do is wait until until betaflight 4.3 is finalized before trying to tweak much. It's coming pretty soon! Next week is release candidate 1.
@@JohnCuppi Thats great buddy will print my own thanks again 👍
Yea the tune was bad if you ask me, very jittery, but just up the d using the slider (not the values) in betafligh to about 1.2 from the stock level that seems to solve the oscillations.

@@JermieMarasigan You should report it to the ExpressLRS devs or ask about it in the group. Someone might know. Or will know what to do to fix it. 🙌
Incredible range! What does the hertz mean in FPV in relation to the power level?
Hz is the data packet rate. Higher packet rates mean lower latency. 250hz is what immersionrc ghost runs on. ExpressLRS can run an even faster packet rate at 500hz. Unless you’re doing extreme long range you want to run the highest packet rate you can. And 1 mile in an open field is effectively almost nothing to ExpressLRS which isn’t surprising at all - but that the SPI implementation works so well is fantastic to know.
Battery life or vtx will be a problem with this drone before the SPI receiver EVER hinders it.
@@JohnCuppi Thank you, John.
Love ELRS and great video!
I saw that you have sky zone goggles. I have the 04x goggles and still having all of the reported problems with them. What firmware version are you on for the goggles and the steady view receiver? And what antennas are you running?
Hey Chrys, thanks! Sorry to hear that about the Skyzones. I am running 2.3 beta firmware, Steadyview receiver 20210422 v2.1 hardware revision. My antennas in this video are the lumenier double axii 2 long range and a menacerc patch antenna. This flight was just conducted in diversity mode. Lately some of the SkyZone group posters have been posting a different problem that I've never seen before, bad reception even /with/ a rapidfire module and no matter what mode they're in. As if there's something wrong with a recent batch of the goggles themselves. Hoping that's not the case. Are yours bad even in diversity mode too?
@@JohnCuppi my goggles were purchased a year ago. I have two modules. One is hardware version v1.2 and the other is v2.1. Daniel with SKYZONE said that this combo would have no issues. I am also on firmware 2.3 official. It's not bad, but definitely has a lot of room for improvement. I fly mix and diversity but prefer mix mode. They are awesome goggles, just wish they could get this sorted out... Had these for a year and still struggling with them.
@@CXBFPV I would just get a rapidfire module. It’s direct fit and fully compatible. Just need to buy a cover/door. Mix mode works well on the majority of models that I fly on steadyview but on some it’s catastrophically bad. It comes down to the mixer not working well. Skyzone has another new module coming out with 3 different mix modes, called the steadyview X. I think the problem is that there is no one-size-fits all mixer. They make a change and it does a better mix for one cam+vtx type and breaks another. The new module will also feature a screen. Unfortunately they said this requires an entire new module to do which is a huge bummer. 😞

excellent video, thanks! I have the same quad and I have a question: what's the PID Loop Frequency you're using? 4kHz? with the default value, I had a CPU load of over 60%. but I'm running ELRS at 500Hz, maybe that's why? what are you running? thanks!
betaflight 4.3 and 8k/4k using dshot300, I have a CPU load of 12%. my expresslrs module was set to 500hz but the tango2 itself will only process 250hz for your control. I do not think the ELRS is what is causing the high CPU load. What was your default value set and what bf version was yours running?
@@JohnCuppi it came with betaflight 4.3.0 RC1, same 8/4kHz as yours.
@@pgabrieli Sorry -- I just rechecked and I accidentally gave you the number for port utilization. CPU load for me is actually only 12%. So I'm baffled as to why the CPU load would be so high for you. I even have the accelerometer turned on mine, which tends to use a little extra CPU. You can disable expresslrs to see if that fixes it but on the board it's set to 500hz for me, I have never rebound it and set it to 250hz yet. Try flashing the newest btfl 4.3, mine is running firmware released on: Oct 11 2021 so it's not RC1.
Hi, say please, which battery do you use?
Great video and review of the SPI Elrs John 👍👍. I only have one quad with the ELRS on it right now and it is so enjoyable to fly. I fully agree with you on the FrSky spi receivers. One quad will do just fine like my original Crux3 and others fail safe randomly. I'm just going to convert my spi boards over to external Elrs receivers once I figure out how to do that. My Crux3 will be one of the first and a little Cine8 will be second. Moving forward I'm only going to buy boards or quads with Elrs. That Crux35 I think will be my next quad purchase.
Thanks for the compliments! I think almost everyone is tired of FrSky SPI receivers and we definitely need to move on -- but until now I don't think there's been a viable replacement. For a while there was at least the redpine protocol but I think that was too complex. There is one bummer -- the requirement at the moment to only use betaflight 4.3, when so many great tunes out there are for lower versions. But, everyone has to upgrade eventually, right? I'm also hoping Emuflight will add ELRS SPI support if they haven't already, that would be a huge help. How did you like the Cine8 by the way? I never got around to building it.
@@JohnCuppi the cine8 is on the way and hope to have it by Christmas, but I know already that it will benefit from an elrs receiver. Will let you know how it goes.
Hows the Cruz35 going ? Do u still love it? Is it worth buying ? Do u fly HD >
Yes I still love it! I bought a second one on sale! My first one is still going strong. And it's funny you asked about the HD. With the second Crux35 I installed the HDzero system in it. Been testing it out the past couple of days with good results. I can solidly recommend the Crux35.
@@JohnCuppi Nice look FWD to the review on the HD Zero then ! I have the DJI goggles so I am keen on the Cruz35 Air Unit. I just broke my FrSky X lite radio so now I am thinking of buying the DJI radio as I am always going to Fly with the Air Unit systems. Am I doing the right thing ? Not sure about the DJI radio. I don't know !!! lol. Should I buy a radio like yours ?
@@wokbok43 I personally would not recommend the DJI fpv system radio; it isn't 'bad', but I don't think it's worth locking yourself into only flying anything DJI. Also, it is easier to buy something like the crux35 HD with expressLRS and just bind straight to the board like I am in this video. They don't make this in a DJI bind-and-fly form, you would have to solder the caddx air unit to the receiver pads on the board. Not hard, but just something to consider.
Tango 2 like I have would be a solid choice, but you can also look into the radiomaster tx16s if you prefer large size radios. 👍 I have DJI FPV goggles as well but I am trying shark byte just to test something new out basically.
Do you ever boost it to the 250mw? What circumstances would you need to run higher mws?
No. In fact as an experiment over the last few months I’ve just flown it at 50mw Link quality stays pretty stable. But if you look at where I’m flying it’s typically open spaces like public parks, etc. if I was flying inside an abandoned building I’d go to 250mw.
Also - staying in 50mw conserves my Tango2 battery life significantly. The module I have can passively cool itself with the power set that low, running the fan is not required. (But, you can if you want to.)
@@JohnCuppi great advice. I was flying at 100mw for a while then bumped to 250 thinking it was better. I didn't notice a significant change in battery life but it was warmer. I think I'll lower it back down thanks to your advice. Thanks.
Heya! What configuration do you use? I'm going to buy the drone and still dunno how to make video that clean :(
This VTX is an OpenVTX 400mw, with the standard antenna on the crux35. My goggles are Sky04x v2 with a mad mushroom antenna and menacerc patch.

@@k1ortia Watch that connector on the vtx as well. In my experience it came off / pops off too easily. I reinforced it with heat shrink, and it hasn’t popped off since. It’s a little weird to get a piece of heat shrink around the corner of that triangle shaped VTX though.
@@JohnCuppi I'm wise to that now brother.

Well, this would be a popular video if your results truly work across all models and aren’t hardware based. 550m is an amazing result for frsky SPI whoop. I’ve never ever seen that. Was this with the mobula7 1s or 2s?

@@JohnCuppi okay ty in price its much better then the original hdzero goggles
Awesome review and flight my friend. I do agree more companies are going to get on board with micro SPI. As much as I love TBS tracer/crsf. I see them having to step up and compete or move out the way like Fatshark did.
Thanks Chris! Bold comment! 😃 for me I strongly believe that crossfire still has a solid place in the market; and it mainly comes down to quality control of hardware.
There’s unfortunately some really horrible ELRS module hardware that users can step in right now, in part because _anyone_ can make it. It’s a blessing and a curse.
Some of these companies have been shamed and embarrassed into doing better; because their mistakes can leave lasting marks on the reputation of ELRS.
But you are right that they are going to lose out on ELRS for micros if they don’t do something there, and frankly, they may have already lost the battle there as it is. I don’t see any of the main BNF quad manufacturers caring to integrate XF when they can just go with ELRS and profit from it.
Do I need that module to have that range? I just have my ExpressLRS transmitter what if I don’t want to use the module? What’s the range I can get without the module?
No the range is not module specific. If your ELRS transmitter can do 250mw or higher then you’ll have the same performance (generally speaking).

Great Video mate! I will keep my crossfire...
Thanks! I’m not dumping crossfire either - but, any new micro class quads I can get will be ELRS if possible. Tired of FrSky SPI, it’s time for a change.
Yeah my frsky made it 300m. My elrs I've made it further at 25mw but i can raise it to 1w 😆
300m is not bad for SPI FrSky actually. The problem with it is there’s lack of consistency. I’ve had SPI frsky no good past 50m-100m, made sure the antenna was good etc. but something was just crap. SPI ELRS has been really good.
@JohnCuppi yeah my spi ekrs has been great but most my whoops with built in elrs are on a uart which is nice I can update elrs firmware separate from betaflight
I must be doing something wrong as I can't seem to get this kind of range out of my mobula7 elrs using the happy model es24 TX pro, even at 500. Something ain't right
But your mobula7 1s elrs has one major difference -- it uses a ceramic tower antenna, not a T-antenna like on the crux35! This is a very important distinction that will always result in significantly less range with ELRS. Also if you want 'more range', dial down the packet rate from 500hz to 250hz, you can even go 150hz. The higher the packet rate, the more demand on the link, and range will be decreased.
Doing a straight shot on 250hz I was able to get 1.4 miles with mobula7 elrs 1s. ruclips.net/video/RASKniA6OV8/видео.html
@@JohnCuppi Ah ok I guess I didn't see that the crux used a t ant. Yeah I know that the ceramic tower isn't optimized for range but looking at the video you shared, even at 150hz on 500mw I really am not getting that range with my mobula7 like in that video, which I'm thinking might be the module as I also have another elrs whoop and its about the same. Maybe I should try another brand.
How the bloody hell do you bind it to the BetaFpv Elrs Module?
Is the betafpv ELRS module running ExpressLRS 2.0 or 1.0? This drone currently ships with betaflight prerelease 4.3 which has ELRS 1.0; but you can update to the newest version of betaflight that includes 2.0.
@@JohnCuppi The Module is on 2.0 How do you update the quad to 2.0? or is just easier to have everything on 1.0? Cheers mate
@@k1ortia If you want to start flying today right now, it's definitely probably easier to just have everything on ELRS 1.0 and then bind. It 'just worked' perfectly for me. But, the way forward is definitely to upgrade betaflight on the Crux35 right now to the very newest betaflight 4.3, which will bring the ExpressLRS integrated receiver up to 2.0. 👍I have not updated my crux35 or happymodel ELRS module to 2.0 yet. Betaflight 4.3 is going to be fully released to the final version any day now, that's when I'll upgrade my stuff. 🙂
@@JohnCuppi Ah, ok. i shall give that a try, only issue i had with the module when messing about with firmwares, was that you loose the use of the Oled,s and the screen. iv just managed to update the Crux 35 to version 2.0. so hopefully ill have something in a bit. Never had this headache with Crossfire
@@k1ortia ELRS development is advancing so rapidly that unfortunately these problems have come up. Since you got the crux35 on the newest betaflight 4.3 and for 2.0 setup there, then I wouldn’t go back to 1.0.
Personally I’ve had more than my fair share of problems with crossfire binding issues over the last couple years with the Tango2. 🤷♂️ ELRS still has a higher learning curve at the moment but it’s getting there.
May i know what is the flight time of that crux35?
It depends on the battery, but so far for me, all LiHV:
530mah GNB - 4 to 5 minutes (pushing it, but great weight on these!)
660mah GNB - 5 minutes (comfortable 5 minutes)
720mah GNB - 6-7 minutes
So my favorite is the 660mah.

@@JohnCuppi thanks!
Hellomy friend, a question came up related to the output power of the vtx. Does that generate heat on the vtx, right? If so how do one keep it from getting too hot and damaged when not in fly? I know a fan when working with the drone does it, but when in the field, let's say I have to go pick it up and takes me a few minutes. How much time or heat can they resist? Thanks!
Wrong. SPI is a hardware protocol that transports serial data from point to point, it requires three or four signals to achieve MHz bit speeds. The Semtech SX127x(900Mhz)/SX1280(2.4Ghz) LoRa hardware combined with an Espressif or STM32 Processor is the hardware used for ELRS. The SX1276/77/78/79 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using Semtech’s patented LoRaTM modulation technique is how this is being done, the existing non ELRS transceivers use hardware that does NOT have this level of encoding. The SX127x/SX1280 + STM32F4 or Espressif combination has been around for years, using it to transport ExpressLRS protocol was a given since nobody has deep enough pockets to create something better. FYI: Both the SX127x and SX1280 parts can only be connected using SPI, not I²C or UART, the STM32F4 or Espressif talk to the outside interface with serial uart.
Thanks for the info!
Shalom bro
Range test yeah right, how much further you think you could have gone?
not that much farther, but not because of expressLRS being a limit at all! The battery life on this quad wouldn't make it. I was already at 3.6v average voltage by the time I got back.
There is not the slightest relationship between "range" and "SPI".
100% correct on paper! However, just casually ask anyone what they think about “SPI based receivers", the term has become synonymous with “shitty range.” This is only because so many hardware implementations of SPI based FrSky and FlySky receivers are bad. The FrSky D8 protocol being horribly old and slow makes matters even worse. "SPI based receiver" just has a terrible reputation.
So, it was refreshing to fly a modern, fast link protocol implemented via SPI receiver that’s built correctly. So it works _exactly_ the way you would expect an external receiver to function, which has virtually NEVER ever been the case for FrSky SPI.
I did this video in hopes that anyone who thinks choosing ELRS as SPI would be the same old shitty experience they had in the past with other "SPI receivers", would best reconsider that thought because they'd be missing out. Hence why in conclusion, this result is really not that surprising at all to those who know that.
@@JohnCuppi Alright;) I just didn't like that the impression was left that SPI is a bad standard, people quickly get confused on tech terms.
SPI is better than USART in almost any way. Faster, simpler and likely more stable in terms of EMI stability which is always a concern in quads.
Express-LRS is clearly the way forward, FrSky has always been a pain.
Also given it's open source and open hardware there is going to be a lot innovation coming.
@@haka8702 Well, I'm sorry. I didn't mean to give that impression when I made this. In fact, I was hoping that just the opposite would be cleared up by this video... that SPI is not what we should associate with being the problem. It's just all the bad FrSky and FlySky D8 receivers. I sent this to a few friends of mine before posting it, and they said they would now LOVE to see ELRS as SPI on their whoops instead of FrSky. They did not know that an SPI receiver implementation that could function extremely well like this.
ELRS is the way forward clearly as you said, and FrSky SPI receiver implementations will definitely no longer exist for any new products. There is just no reason to keep implementing old inefficient protocols that never had any official support from the manufacturer anyway. That was one of my bullet points for ELRS over FrSky, fully open source and an open hardware spec. There is one small disadvantage to UART vs. SPI receiver that I have run into -- to update the software, a full flight controller firmware update is required. This has been a bit of a pain with updating to expressLRS 2.0 while betaflight is still in 4.3 rc at this time.
I will have my second ELRS quad with an SPI receiver arriving tomorrow, the Mobula7 HDzero, I'm sure the range will be excellent and as expected. 👍

So viewers could enjoy the nice HD video but also get to keep an eye on what my actual visual was.

Just remember that. If there were just a picture with no sound, it would suck. If there were no video and only audio, it would still suck. Both are cool, but add more media for a better follow-along by viewers. You have so many views but very little likes, probably because of what I just explained.
It may be rude, I won't argue about that, but at least you know what the problem is now. And frankly, I don't give a rat's south end about how it makes you feel. I don't see anyone else taking the time to give you honest feedback. Your video would suck less with considerably timed flash captions. You're welcome.
This isn't supposed to be a movie dude, it's a simple range test. To inform exactly of what I intended: what kind of range can you get from this drone, and what the video and link quality is like. Then talk about expresslrs. That's what everyone is watching this range test for to see how it did.
300 likes is alright for a video with 13k views by the way, too. 3% to 4% like ratio is considered a "great" ratio by marketing, and this is around 2.3% so it's not bad at all. And I'm not even begging the viewer for likes until the very end of the video, I'd have more if I reminded people in the middle.
57% of viewers are still watching at around the 6 minute mark which is pretty good on a 9 minute video. But I need more "multi media?" Considerably timed flash captions? WHAT? No.
I feel like I'm having a conversation with an AI bot. Do you even fly drones? Are you just browsing? How did you even find this video?
@JohnCuppi that's the problem. Communication is a 2-fold event. You can have whatever impression of yourself that you want, you can think you're the best communicator on Earth, but it's up to the receiver whether or not that information has been relayed in digestible format.
Out of 13k people, only 300 saw fit give a like. I didn't know you were asking for likes at the end, I didn't make it that far. I found a different video with captions to follow better.
Yes. I design, build, and pilot quads.
Your video was supposed to be about the receiver range, I was expecting it to be the predicate of your video. I didn't expect it to be about HD visuals and your excitement. You don't have a good read on the audience's pulse. And that's like step 1 of public communication.
You can take it personal if you like but I don't know you personally. I'm just telling you what you missed and why I didn't like it.
