Yup picked one up for $30 on pyro!!

[@kurtzFPV]

Had already converted my original crux3 with the ep2. Love the 2s and fly it most every day. Had some weird disarms at close and medium range on my 5" and my phantom hd so am back on crossfire with them for now. I want to convert everything but I'm gonna have to gradually work back into it. Just did a quick test on my new crux35 HD with elrs and so far so good.

[@bradleybeaudry8935]

Yes, the migration has begun. 6 of 24 converted so far. Probably won't do all my whoops, but did change the board in a mob6 19000kv to the elrs aio. Definitely felt a difference in flight performance, and of course, range. Thanks for the information Nick. Great video

[@slackerinmotion]

PH2.0 to XT30...Severe voltage sag when I used rolled ph2 connectors. I then filled the rolled pins with solder. 10 packs later, still sagged. Changed to solid pins, flight time increased by a few seconds. Then the battery connectors started to get warm/hot. I skipped the BT2.0 and GNB27 upgrades and went straight to XT30 connectors. 20 packs later, my flight time has doubled and the voltage sag is limited by the internal resistance of the battery.

[@nikotttin]

Thanks for testing!

[@KrotowX]

PH2.0 connector indeed is a good part of voltage sag problem. When my Mobula7 PH2.0 batteries died, replaced connectors to BT2.0 connectors and purchased batteries with BT2.0 connector. Got like 20..30% less voltage sag in result. With my usual not so punchy flying style I now have 3.3V left in battery after 4 minutes. Where PH2.0 batteries after same time ended with 2.7V. Also it is worth to reflash ESCs firmware for 48/96 kHz PWM and RPM telemetry support. BLHeli_M 16.9 etc.

[@amin0_acid310]

Late to the game I know. I went with a Jumper T-Pro + elrs module when I first got into FPV early this year. Glad I did thanks for helping to push me towards ELRS, really enjoy it. Saw this one and picked one up. 2nd time plugging it in to check settings some of the magic smoke came out. Can't fault HM for the 5 months shipping, but they sent a replacement FC, in my hands about a week, amazing. I haven't got a lot of air time on this one, but what I have had it's a hoot. Shame the bad time of the year is upon us. After some winter indoors whoop boot camp, I'll be really looking forward to ripping this that first nice spring day. Thanks for the videos, old and new. Really helps out when looking for gear knowing the pros and cons.

Thank you. You are my favorite micro reviewer.

[@NickBurnsFPV]

Thank you. Appreciate the compliment.

[@tlewis3083]

After reading the many reviews of elrs vs older protocols is seems that elrs is the equivalent of driving a car that has a computerized throttle (drive by wire) versus an older vehicle with a mechanical gas or a new car with power steering versus an old car with mechanical steering!! The latency represents the slack in mechanical controls. I'm always amazed how our brains become so sensitive that we can actually detect such differences based on milliseconds. Very cool! I see examples of this all the time when one of my customers has a problem with their new computer and has to temporarily use an old machine whike their new systems is fixed. What is actually split seconds feels like minutes to the user. another crazy thought is that elrs is still somewhat in its infancy and has a lot of room for improvement. Sorry to geek out but it is really fascinating.

[@CallistoFPV]

Elrs and ghost lower latency makes you feel more present, I love it.

[@SPIT_FPV]

Is it noticable for you? I've not tried yet.

[@lodriguez]

Phillips screws are usually nylon on this small drones.

[@crash_lander]

About the solid pin connectors ruining the 1s batteries.. I think it’s true. I just realized it when you talked about it in this video. My newbeedrone nitro nectar gold 250mah ones barely lasted a month and my new gnb 300mah ones gave about 4 minutes of flight time but after just 2 weeks dropped to barely over a minute. I wondered if my charger is faulty but then batteries with GNB27 connectors are doing just fine. So it’s clear now the solid pins are battery killers.

[@crash_lander]

Update: Confirmed, solid pins are the culprits for dying 1s batteries. Just replaced with folded pins on two whoops and flight time is just right.

[@DianKuChannel]

Sorry, how long is the flight time with Peanut?

[@KaizerTest]

I believe it now comes with a TPU canopy that is also a go2 mount. And you plug the GO2 into the flight controller plug which is 5v and ground.

6:10 What is the french forest video you are referencing?

[@NickBurnsFPV]

I believe this is the video I recall kzbin.info/www/bejne/pH24nopshMt4r5I

[@OrtexVideos]

Awesome video!! You should do a blind test of the same quad running 250Hz vs 500Hz and see if you can correctly identify the packet rate each time.

[@Cre8ionz.]

18:49 min - if you're using rolled / folded and solid pin, you end up having a worse connection on the rolled / folded pin unit.. At least that's what I guess.. Reason: Solid pin is a bit thicker.. And don't plug in your PH2.0 packs into a balancer port (like these 1-6S Battery alarms with the LED screen

Yeah, I've switched all of my active fleet to ELRS. On the 5" it feels like the quad has lost 10-15% weight, the response is that much better.

[@Dad_with_a_drone]

Hi Nick, I hope you’re well, I need to pick your brain again, so we decided upon the lighting 1 above the nano 2.0 based on vtx, im just wondering if the crux3 2s would be a better quad choice ? The ones that are available for me are frisky spi so I’d have to add an elrs receiver, I know the 1s version is the new version but I’m thinking the 2s would just be more punchy ! I have a crux35 so I’m happy with 4s and I have a few 1s micros but there is a void for me I just need to be a bit smaller that the crux35 and the bonus of the crux 3 is that it fonts in the case with the props on ! So I just thought I’d ask you what you thought ? I also had the baseline in the mix but honestly I’m not the greatest fan of spi elrs, im sat with my finger on the buy it button for the lighting 1 but I just thought I would get your thoughts! Or is there another 3” I should be looking at, I was looking at 2s and budget but I’m not Apposed to 3s if it ends up being better, im in the U.K. and there doesn’t seem to be much info on 3” really, many thanks for your thoughts

[@NickBurnsFPV]

I like the combination of 2inch props on a 2s battery more than 2s on a 3 inch prop. The prop response just isn't the same for quick moves, like flying close proximity or similar. I would still go with 2inch prop and 2s.

[@jacktheripper1784]

I think your right with elrs, it feels much better than frsky, really awesome response

[@sixtofive]

Would you be willing to try a follow up flight with the light weight configuration, but switching out the props for triblade 65mm like the Gemfan 2512 or HQ T65MMX3? With a 65mm low pitch prop I'd be willing to bet this would be an even more responsive flight feel and possibly more efficient as well on those 450 mah batteries. After watching your review I've got one on order, but the shipping time looks like mid Nov. At least by then I should have all the ins and outs of ELRS figured out.

[@NickBurnsFPV]

I would have to test, but these props are very light, I suspect we might only see a small change and it could be more responsiveness but less flight time as the 3inch prop is generally more efficient than shorter props. We shall see I will see what time I can carve out to give it a run.

[@sixtofive]

[@panoramic_life38]

I have this drone ELRS with the Master Zorro that already come with ELRS and it’s impossible to bind! I have a brand new drone just sitting in my house but I can’t use it :(

[@NickBurnsFPV]

The primary issue to binding is we have to ensure the version of elrs is the same major version, so both would need to be on elrs v2.x.x or v3.x.x as of right now. The crux 3 in this video is spi elrs and requires betaflight update to update the elrs version. In that case I think its easier to upgrade or downgrade the radio elrs version.

[@NickBurnsFPV]

The PIDS come stock on the quad. I did not custom tune it.

[@sketchpv3080]

I made the switch to ExpressLRS recently and I’m glad I did! Originally used R9. ExpressLRS instantly felt like my quad was using a cleaner tune. Then I changed to rc interpolation to ON instead of AVG_2 and it felt even better. I’m using EP2 receivers at 500Hz and at 500mW. My 1200mW DJI video fails before my control link. However, one of my HappyModel receivers bricked during the WiFi flash and I bought an early production HappyModel Slim Pro TX module which has the telemetry bug so both those issues are bummers but this ELRS gear is inexpensive enough that it’s not a big deal. I’ve simply turned TLM off using the ELRS LUA script to stop the annoying telemetry alarms.

[@NickBurnsFPV]

It is disappointing the early runs of some of the elrs products have issue. I did see with the new version of ELRS has solved a hardware issues with a particular receiver and a power up issue. Which is amazing. I wonder if they will be able to fix the telemetry issue via software.

When my original Crux3 FC kicked the dust I replaced it with this AIO and ran it as 1S and 1202.5 11500kv motors instead of the stock 6400kv and it was basically perfect for backyard ripping. The FrSky board was honestly terrible with how much it (seemingly) randomly failsafed. Now with the range of the ceramic antenna + 500 Hz it's great. Not as punchy on 1S but hey, if I want a punchy version I can use their X1 AIO that they use on the Crux35 up to 4S (though I also own a digital Crux35 so meh) and a VTX for it.

Why would you want to some that same or worse performance than eLRS?

[@drewlyadventures6258]

can i ask.? flying elrs crux with 360 v2 in 1s, especially when you punchout full throttle, does 5a AIO really handle that kind of punchout even you put the 360v2.? coz i last week, i flew my crux3 crsf (running in 2s)with my 360go v1 and needs doing a full throttle (needed coz weight added of the 360go), one of the motor gave up. after checking it in, i realize that motor is still working properly so my guess is the esc built in on that aio already died(not sure, this is only hypothetically speaking, sry im still new at this), i still want to flew micros and toothpick, but all of the FC aio available for that is only 5amps for 1s/2s

[@NickBurnsFPV]

Yes, it does handle the amp draw of the motor and prop with the extra weight. That doesn't mean it will forever. One item I can suggest to help the esc last longer is to disarm very very quickly when we crash. This means our props should not be trying to spin when the quad is on the ground or stuck in a tree. If the prop cannot spin a voltage spike will occur in that tiny moment and that can burn one or more esc.

[@Acestrex]

The first manufacturer that makes a 3s aio elrs 400mw vtx is going to sell a ton of them!!! It just has to happen then analog will definitely stay around for a while longer. I still love my 12a aio analog setups but adding a standalone aio,vtx,elrs is still adding to much weight. Geprc,namelessrc,hglrc, or others please get to work and make it happen!!

Hi Nick, first of all thank you for your videos and amazing job.

I currently fly with a GNB 650 mAh and I have no idea what is happening

[@NickBurnsFPV]

What is the voltage reading of the battery before you start to fly?

[@chiaracozzolino2907]

@@NickBurnsFPV it seems normal, I read 4.3 V

[@NickBurnsFPV]

@@chiaracozzolino2907 Is that a reading from a battery checker or via the quad and the betaflight osd? Take the props off and plug in usb and use the betaflight configuration app to test motors. Move the slider up some and see if all motors are reading the same level. Move it up some more and visually note the motor levels again. Do this up to about 80%. Do these readings fairly quickly as we don't want to have the quad plugged in long without flying, the board will heat up without air flow and could overheat causing damage. But if the motor levels all move evenly and normally up to 80% that could indicate the battery health isn't as good as it once was. Discharging to low or keeping it charged for long can cause it to deteriorate over time.

@@NickBurnsFPV Thank you for the help and the availability. The GNB HV 650 MAh (60c/120c) I am using are practically brand new. I read the right voltage from the Beaflight OSD and also from the battery checker. Checking the motor as you suggested, I notice that one of the motors behaves a little bit differently: the R value is significantly different (I think) from the other motors. With the master at a certain level (slightly more than 50%) for the first motor R = 11000 while the other values are around 16000. I tried to find out if this is something that has to do with the motor itself or its connections, but if I switch it with another motor, I have the same problem in the same "exit" from the board.

Hey Nick, sorry for the noob question, I'm new to this. I've ordered yesterday a BetaFPV Literadio 2 with builtin 2.4ghz ELRS, and I'm thinking of getting Eachine EV800D, do you think they will be a good starting point with the Crux? Any suggestions?

[@NickBurnsFPV]

My only concern is with the lite radio 2. Betafpv has had some difficulty with their quality control on that form factor radio. Namely the wires on the gimbals have come off for some people. The "fix" isn't terrible to resolder, but most who purchase that radio aren't ready for soldering yet. I have not read recent reports of that issue so they could have resolved their issue. the ev800d have been a standard for starting for a good long while, they should work well for you.

Need to replace my betafpv lite radio 2 with a radio with ELRS but want better gimbles and a screen. Seems a shame to not have ELRS as internal module.

ELRS is fairly new, we may see more radios with internal modules, at this time on the new betafpv lite radio has an internal ELRS module. I have not used it or suggest it as there is no screen to make lua script manipulation reliable and easy.
