HappyModel PP ELRS RX. A tiny magic-powered wonder! Supplied by YourFPV

HappyModel were the first to market for commercial ELRS gear, so let's test something tiny. It's a testament to the idea of ELRS that, in this video, I'm using a TBS radio a Namimno module, and a HappyModel receiver, and everything plays nicely together.
This receiver was kindly supplied by YourFPV for review, so please take a look at their website if you are in the market for some gear.
You can see the HappyModel receivers here yourfpv.co.uk/...
The Mambo product range here yourfpv.co.uk/...
and the Namimno gear here yourfpv.co.uk/...

Changed all my receivers to Happymodel 2.4 ELRS some time ago. No regret.

[@CurryKitten]

Good choice !

[@bedrascal]

ELRS is the future. Everything is compatible with everything.

[@CurryKitten]

I like this future we now live in :D

[@helioseclipse337]

No more separate receivers, will be integrated in FC.

[@GBoniFPV]

I got all my 5inch on either PP or EP2, and I haven't failsafe. These little rx are amazing and cheap. Welcome to the club

[@CurryKitten]

Yes they are!

[@turboomni848]

Thanks for the review. I am also just starting to dabble in ExpressLRS and I am sold. No hassles with firmware like frsky. Easy to set up. I'm done with frsky.

[@CurryKitten]

FrSky can do one for sure. I've had issues in getting modules flashed (see reviews on the Namimno and BetaFPV kit) but once sorted, the experience has been great.

[@ched999uk]

That little ELRS rx is doing amazing. Great test and just shows how things get better and better. Looking forward to some more range tests. Hope the knee keeps improving.

[@CurryKitten]

Isn't it just! I was hoping to fly in the next week, but it's rain rain rain. Hopefully soon though, I've got a little backlog of quads to fly :)

[@k1ortia]

i bought 6 of these tiny receivers, 3 with antenna and 3 with the ceramic one. Still bloody waiting for my Namimno module to turn up though. Cant wait to try it all out

[@joshgraystone8815]

Same here bro lol

[@offgridgaminguk]

@CurryKitten the Link Quality isn't important, the rssi dbm is what matters, -30 = fatastic, -108 = your going to failsafe. You'd have to go a good 1-2km to outrange those ceramic antennas.

[@CurryKitten]

I can't deal with that scale :D I know this is the absolute best and most accurate way of thinking about it, but nope - my brain just can't work with those numbers.

[@johnmansley9534]

Great vid Wayne 👍

[@CurryKitten]

Thanks 👍

[@JyeSmith]

Double check the bad:good packet ratio when on FreedomTX and 500Hz. It should be 0:500, but you have 0:216, because the mixer syncing doesn't support 500hz. But on 250Hz it will display 0:250. I also have a theory about the heat shrink that HM ships on the SMD antenna receivers. I think it is staining the antenna solder and causing breakages. Just keep an eye on it or remove the heat shrink. Racing! SMD antenna all the way with racing :D

[@bigscreen3968]

good review!

[@MCsCreations]

Fantastic flying and review, Wayne! 😃 Yeah, I would say this little receiver is as good as a XM+! If not better! Anyway, stay safe there with your family! 🖖😊

[@CurryKitten]

Thanks MC - yes, I would have been equally impressed if I had that sort of signal on an XM+ at that sort of range. It's an exciting new world :)

[@heliharris69]

Pleased your back and up and running (or at least walking). This ELRS gear is certainly impressive..judging by your enthusiasm its one that you.. and a lot of other reviewers rate very highly...I have an order placed with Banggood for the Nahhhmmmino radio module and receivers..plus a couple of the HappyModel ones...but as usual with Banggood... says there in stock when you place the order...then its a monthly update as to when its ACTUALLY going to be in stock..so some time this year i hope to try. Great.. informative and interesting review...as always.

[@CurryKitten]

Yes - I like ELRS for a few reasons. Firstly it works very nicely in terms of latency and range and secondly I love the fact it's any module on any radio with any receiver. It stops people having to tie themselves to a brand. That said it does need to get a bit friendlier in operation and have some extra protocol support - which it lags behind in comparison to the likes of TBS and IRC, but it's a fantastic start so far. Hope you get your kit through soon !

[@johnmansley9534]

As primarily a fixed wing flyer I have put an elrs receiver into a Zohd Drift with a small Matek fc running Inav. Early days but and still learning but looks really good. Hopefully the system will develop for fixed wing to fly more complex models.

[@CurryKitten]

I think ELRS are slowly catching on to the idea of fixed wing flying. There's talk of more full range channels, and I believe someone else is coming out with a board that does CRSF to PWM so you can fly a model without a flight controller. It's early days, but what is there now is impressive - I hope development continues to cover everyones model choice

[@johnmansley9534]

@@CurryKitten Yes, Ghost can output sbus to convert to pwm so as you say the Elrs developers will hopefully move forward along those lines. 👍

[@TitanFPV]

I didn’t even know you could find the PPrx anymore. Since I bought my first one, I haven’t seen them anywhere. Some flight controllers don’t like the bf pass through flashing. I have several EP2s.

[@CurryKitten]

I can still find them around, but I would take a guess that given that it's not much more for an EP2, lost of people would just go for that instead and have wifi. A case of natural selection?

[@EnglishTurbines]

Yes, awesome range...considering CRSF 868mhz will do 30kms on just 10mw..This 2.4g ELRS stuff is going to take over IMO..Hope you knee keeps improving M8..🤔😀👍

[@CurryKitten]

Some crazy distances on both frequencies for ELRS as well github-wiki-see.page/m/ExpressLRS/ExpressLRS/wiki/Range-Competition the idea of running out of range seems to be a thing of the past now :)

[@willedwards7679]

Not to mention much lower latency than crossfire

[@CozzyKnowsBest]

Oooo much excite. Its like what the Russian DIYers did for UHF.

[@licensetodrive9930]

I'd have made folding TPU holders for the PP but Happymodel only sent me the EP1, EP2 & ES900RX receivers.

[@bedrascal]

Happymodel EP1 & 2 both the same 10mmx10mm 1 has proper antenna, I use it on 5 inch freesyle quads.

[@CurryKitten]

Yep - all very similar. The EP1 has a decent antenna and wifi, the EP1 is almost the same as the PP, but has wifi to updating the firmware. All of them seem like great rx's

[@primoziskra6394]

I get EP without a heatshrik on. It was seperete in the packet. But be careful. wWhen I heat it to shrink it brake an antenna. I change it with 32mm wire ant works fine.

[@allenlong1445]

You just got yourfpv another sale dude you need to sort out a discount code or an affiliate link so you can get kickbacks as I'll be buying a RM tx16s when they get them back in stock prices are good also I just got myself a TBS crossfire Rx best price in the UK I think so thanks you got me in to there store.

[@CurryKitten]

Gaf's already a Patreon of mine, so I think he's doing enough :) It's just great to have some Uk based stores to get stuff fast and without all the hassle of ordering from China!

[@nikotttin]

To be fair, my 2S 2’’ whoop and my 1s whoop still have the SPI RX and it’s plenty good range for what you can do with such toys. For 2.5 and 3’’ toothpick, yep, they all transitionned 😉 AngryDon actually went almost 1km out on SPI!

[@CurryKitten]

I think SPI is ok for inside, but I had loads of issues outside with little quads. That said, it's usually about the antenna they come with rather than anything else. The little Emax TinyHawk II Freestyle had an SPI receiver with a decent antenna and that worked a lot better. However, hopefully from now on, the SPI rx wiil be ELRS based instead of D8

[@fatboyfpv3658]

I think the PP's are no longer, discontinued, but we do still sell the EP2's which have same range and ceramic antenna

[@CurryKitten]

I don't know if they've been discontinued, I can see them around a few stores. I don't know if people may just prefer to pay a little bit extra for the EP2 so they can firmware update via wifi, which possibly mean that the PP isn't as popular

[@willedwards7679]

@@CurryKitten I heard that they were discontinued due to the chip shortage

[@TakeItToTheGround]

It just begs the question on these small builds why don't they also make VTX's with ceramic aerials?

[@BrandonBeans]

Here I am flying around super far on 50mw. If I need to go more 1km then I'll bump up to 100mw for security

[@CurryKitten]

Yes - I picked 100mw because most modules seem to do that. I could fly way lower and still have no issues

[@wdavie27]

curryKitten hi can you tell me what size of sd card you use in your jumper t 12 i was trying to flash elrs firmware but not enough memory on my sd

[@CurryKitten]

It's probably a 32GB card. That's not because it's how much it needs, it just that they are dirt cheap and so there's no point in buying a 2GB card for almost the same price. I'm really surprised it's run out of space, unless you have a very small card and all the language packs and everything you can possibly fit on there. I created a .ELRS pacakge for an R9 conversion a few days ago and it was only 43k in size, for other modules I've only ever seen at up to around 1.2MB

[@stevefox3763]

I don't have ELRS (yet) although i could flash it to my R9 gear but I'm thinking, if the stock 2.4 gear gets such good range, what the hell will it do amped up??!! I've always run my regular 2.4 amped to 2w and have bi directional amps already, i actually have a 4w amp here which ive yet to use, now I wanna try 2.4 ELRS with it :)

[@willedwards7679]

You won’t need anything above 500mw for elrs, you literally won’t be able to fly far enough to beat it, your vtx signal will be gone long before

[@balajiprasad9046]

Looks like if you loose the quad in the woods it is end of the story...but you didnt loose which proves the magic of ELRS. Certainly it is a good candidate for whoops and toothpicks.

[@CurryKitten]

Haha, there's no chance of finding that little thing. I'm very likely to lose it through the lack of the lipo lasting long enough, but the ELRS signal held up very well

[@RCThis]

I wander of VIDEO transmission will be shrunk down like this?

[@CurryKitten]

There's already VTX's this small. In quality terms though, have a look at the RushFPV Tiny Tank

[@RCThis]

@@CurryKitten I'm referring to the antenna part*

[@CurryKitten]

Ah, I'm with you - yeah, that would be pretty cool to have nothing sticking out.

[@edcbabc]

Does that TX module meet all the UK RF legal requirements? I assume 100mW is the limit for that?

[@EnglishTurbines]

You won't need more than 100mw...🤔😳🇬🇧

[@edcbabc]

@@EnglishTurbines no probably not. Was wondering if it met the other legal requirements or not.

[@EnglishTurbines]

@@edcbabc China leave it to you to obey local RF laws...It's unlikely anyone will check anyway...🤔🤔😳😳🇬🇧🇬🇧

[@edcbabc]

@@EnglishTurbines well yes but it is nice to know. Look at the fuss over frsky international and eu-lbt. I assume it probably doesn't meet UK legal standards, then.

[@CurryKitten]

I think the 2.4Ghz output rates is 100mw for the UK. It's up to you to make sure you stay in that rate... that same as you'd always make sure to have a spotter and fly at 25mw VTX... just like I always do :D

[@acknack151]

you are in UK? I thought you are from Germany...

[@CurryKitten]

What gave you that idea !? Very much from the UK :)

[@55amps]

This rx or the ep2?

[@CurryKitten]

If you want this form-factor, then I always find the wifi chip much more simple for flashing, so the ep2. But if you model has the space, I'd always get an RX with a propper T antenna like the EP1 (IIRC)

[@55amps]

@@CurryKitten it’s better on the range ? Or the same as the ap2

[@jklong03]

Ignore-I am an idiot You call it a PP but it's actually an EP2 🤔 Well, it may be a returned one. They are not generally supplied with the heatshrink all ready applied and wrong label on package!

[@licensetodrive9930]

The PP & EP2 are different receivers. From reading Happymodel's website, the EP1 & EP2 are based on the PP and use wifi for firmware upload whilst the PP's firmware upload is by Betaflight pasthrough.

[@CurryKitten]

I know I've cocked it up in the past, but I usually at least know what I'm reviewing. This is a PP rx, the EP2 looks a lot like it, but the EP2 has a wifi chip onboard so you can update over wifi, the PP doesn't and hence needs to be updated via betaflight passthrough

[@CurryKitten]

Exactly right @licensetodrive

[@CurryKitten]

@John Grzeskowiak Yes - a PP, also evidenced by the fact it had no wifi chip (like the EP2) and said "PP" on the board (as well as the packaging) :)

[@jklong03]

@@CurryKitten I apologize for the mistake. I swear when I ordered right after they released them that the PP only had a dipole!

[@yodayedi2325]

Compared to frsky r-xsr, is it less, same, or more range?

[@CurryKitten]

With the ceramic antenna, or a regular. It'll certainly go much further with a proper antenna. With the ceramic - not sure - will then depend a lot on the antenna config of the R-XSR and the type of flight. I certainly didn't feel on that sort of range that it was any worse. I've got another ceramic rx from Namimno, so I might put that in another quad and see how they compare.
