Frsky Horus X10 Latency Test

[@ArchmageAU]

Great work. Thank you so much for doing these tests. Most of us do not have the knowledge, equipment or time to do it.

[@simons5758]

Hey great video. Was that done on openTX or the FRsky OS? It would be interresting to see if it makes a difference

[@Zikatus]

I second to that question.

[@bryanfpv]

Me third

[@ArchmageAU]

If done on FrOS, would be interested to see if OpenTX changes the latency. Really would be a software acid test. It would be possible for programmers to get into the source of OpenTX and find ways to optimise for lowest latency even if this means bypassing features. (Could also benefit the Taranis too).

[@xnoreq]

@Drone Mesh I too would like to know: Was that done on openTX or the FRsky OS?

[@fellstar]

@Drone Mesh did you every respond to this somewhere?

[@AerialMediapro]

what receiver have you used on your frsky tests? you assume a software bottleneck but have you considered that the receiver you are using might be your bottleneck. I doubt the delay comes from the TX software simply because when using crossfire it works faster. the tx module and rx pair are most likely the components responsible for most of the delay since those are in fact the components which do the actual radio communication.

[@DroneMesh]

AerialMedia.pro I have tested xsr and xm+ and x4r all same.. Crossfire on the way

[@antoinerivoire]

AerialMedia.pro the bottle would be with the tx. If the crossfire is indeed faster (only marketing data is available, no real world measurements), it would show that the problem lies between the two chipsets and his the talk to each other. Opentx may fix that, but that's not a forgone conclusion.

[@kellysperspective9588]

Thank you very much for doing this test I am a new pilot and a FlySky finally it is interesting to me to find them that the latency on my devices is so long my next question is about rain latency is a Weehawken equation is there a way to get better range with the FlySky fsi6 x

[@henvan8737]

The Turnigy Evolution is an 8 channel radio, so the question is did you switch the X10 to 8 channel mode, were you running OpenTX 2.2 and how did you measure the latency at the RX output, not using Betaflight displayed on your computer screen I trust. I am thinking your procedures are faulty.

[@se_borg]

Thanks for the video. Why didn’t you unplug the connector instead of cutting wires?

[@DroneMesh]

+Sergii Bogomolov because I needed the wires without risk of damaging connector. Plus it was fastest route at the moment.

[@BuzZ.]

Lol, that ARM chip is soo big. I bet it has more processing power than my PC. :D

[@HuguesD]

What is your test setup and procedure ? Are you really measuring the radio latency ?

[@IanF-FPV]

Awesome work. I'm still here waiting on my soapbox for your FlySky mods...

[@DroneMesh]

Gimbals on the way don't worry.

[@zachfpv4493]

I believe TBS is trying to licence CRSF protocol(crossfire) to FRsky or any other manufacturer. maybe FRsky are waiting to implement CRSF?

[@George64G]

Sometimes the truth hurts alot, but Damm man! I was on the fence about to change to Fr Sky, but I guess I'll wait for the great software, ---rework, recompile(Uh mumm!) code shuffle!!!. If it hasn't been said enough Great Work!

[@renzevenir4853]

Can you redo these experiments with several changes? -TX and RX placed approximately 3m and separated by a wall and thick stuff -Remove antennas on the RX side -TX on range test mode -Add interference, use some cellphones to generate Wi-Fi on various channels I think this will be the closest to real life flying. Sure it's a lot of hassle but the results might be surprising. Love your contents!

[@ArchmageAU]

Considering this is done with microsecond timing on an oscilloscope, separating the TX and RX by 3m (with or without interference) may be a little difficult.

[@carrotboy001]

that wont change latency. That would be a noise test of the radios, not latency.

[@renzevenir4853]

Weak signal and interference induce frame lost, and frame lost induce latency. Unlike analog system where the latency is constant, digital system has advanced filtering algorithm which reject corrupted data, thus add more latency.

[@pingwingugu5]

I agree reducing the signal strength would be a good idea. I think putting terminator on transmitter instead of antenna and putting receiver in cardboard box covered in aluminium foil with a small hole would be easier to do than putting TX and RX in separate rooms.

[@Mike-01234]

It's not an analog radio it either works or doesn't has nothing to do with signal strength or interference unless your a 1/2 mile away then distance is going to add latency

[@MCsCreations]

That's actually really interesting. I liked a lot that radio, though about keeping my (bad choice) FS-T6 for longer and, them (until late next year, I think) I would buy that one. But now I'm rethinking it, to go for a FS-I6 next year and wait longer for a FrSky. (Because it's really expensive for us here in Brazil - it's like two months work for many people - not my case, fortunately, but only to you have an idea.) So... Let's see what they do. :)

[@George64G]

MC's Creations Get the FS-i6x it's a great radio!

[@MCsCreations]

George Grazette Thanks! I'm going to look into it! :D In mine, for example, if I want a 3 position switch I'm going to have to sacrifice a pot. :/

[@CodeChief]

Maybe the delay is the cost of bi-directional telemetry. So the X7 and X10 are slow, meaning the Taranis X9D Plus should be similar. The X7S would be interesting because it has "super low latency" on the marketing material (without further explanation). It would be great if you could confirm by getting hold of an X7S and X9D+. Also please test the myth that 100ms latency is added when using the module bay. If that is true then TBS Cross-Fire is also a waste because regardless how good the module is the initial latency would defeat the gain. Anyway thanks for great videos, please keep doing them also for FPV equipment.

[@MCsCreations]

I missed an "Oh no!" after the wire cutting in the begging! :D It would be funny! :D

[@antzd]

Its the Frsky protocol that's the problem, OpenTX software is extremely well and actively developed. Frsky need to cut their losses with sbus and D16 protocol, go back to the drawing board and release something that can compete with crossfire/flysky latency. And to those who keep arguing about how much better the frsky link is with interference, its the same as arguing that a ZMR250 is better for racing than a Floss because its less likely to break in a crash. Sure the ZMR250 is tougher who wouldn't rather have the speed handling of the Floss for a race.

[@HomeGrownCanadianFPV]

I just bought a 10s ... hope I didn't waste my money lol ;9 top notch brother...top channel

[@will193]

Keep it going! Love the videos!

[@ArchmageAU]

Any plans for module latency testing? (TBS crossfire, iRangeX IRX4, etc...) How about latency between TX antenna signal and Flight controller signal connection or RX servo output?

[@DroneMesh]

TBS crossfire on the way... This test was from gimbal to receiver connected to FC

[@jordanbass3210]

That radio is f****** insane gorgeous. As a pincher I would f****** love that I need to save up for one LOL

[@MisterJDee]

QUADBOT FPV I'm a pincher and I prefer the Turnigy Evolution

[@randomwisdom845]

FrSky released their new protocol with this Horus, you should do testing with the latest receivers and firmware.

[@DroneMesh]

RandomWisdom will have it tested within 3 days

[@vladmirputin7139]

Why cut the wire and not just use a pin header?

[@69fox]

Vladmir Putin, hello Vladimir! Can you say when Russia will be great again?

[@scottthompson2481]

HI , l really want this radio and i fly 3D planes so latency is a big thing , do you think it will be resolved soon ? Thanks for uploading your results ........

[@nathanameru7654]

If change those stalk batteries to Tesla 3600mah 18650 li-ion batteries... And attach some lead for charging while I'm at it

[@1up-ET]

Did you see what it does when it's on open TX?

[@brokepilot6969]

I think those rubber things might be vents in case the 18650s go thermonuclear.

[@csskongen]

waw was going to change my turnigy evolution for frsky but come one frsky latency and u radios is big make a smaller form facktor radio for mini quad and better software

[@mxds450]

Have you ever tested the Futaba T8FG?

[@martykracher]

Fuck it! LOL! Great test on a monster of a radio! Thanks for the video!

[@phljns]

Have you tested the latency with opentx or er9x installed instead?

[@DroneMesh]

+Phil Jones nope but will get started on that right away. Will post vid as soon as complete.

[@phljns]

Drone Mesh Awesome!

[@phljns]

Drone Mesh Would be good to see Turnigy 9XR Pro as well

[@smnaol80]

The "rubber play" hhhmmm...... giggles :D Btw, always follow your review, thanks.

[@ryancheesman400]

You need to test this with the R-XSR rx with sbus. This is what the radio was built for. Anything else is just testing legacy backward capability.

[@vit4min4s]

Are you gooing to test the Radiolink AT9?

[@DroneMesh]

I will try to request it from banggood or wait until next month patreon I just ordered the crossfire yesterday.

[@vit4min4s]

Great!!!

[@man125403]

what do you mean by "faster processor"? it's marketing bullshit, cpu freq means nothing to actual "speed" and are barely relative to things like adc conversion speed. horus use this mcu just for tons of IO and hw support for color displays. rgb-if for display and sdram for display framebuffer - ~60 more pins than x7/9d. speaking of latency - it's all about hw/sw architecture, OS. taranis got things like audio, lua, all kinds of channels processing methods. but what's more important is rf-protocols itself. there may be different methods of reliability assurance, so this may adds latency by design. all in all. technically, you almost definitely can write fw, that will overtake flysky on taranis hw. but then you may end up with product, that incompatible with current frsky ecosystem and/or screw up other parameters, it's bulletproofness as example. or functionality.. i don't know, just thoughts. or may be it all ends up with just perfect radio. hope so)

[@DroneMesh]

+man125403 The overhead is pretty big but if this was my company and product I would release a lite version of the firmware for people who care less about all the extra features and just want solid fast long range connection.

[@bennieleip579]

Sooo youre maybe pissing some big guys off😆 at first t-motors, tbs crossfire killer, and now flysky 😆 go get them👍🏻

[@DroneMesh]

I do this for us and not them

[@bennieleip579]

Drone Mesh 👍🏻

[@wrecklessfpv4416]

That is the best answer I have seen in a while, thanks for doing this for us

[@DaveDDD]

How was he upsetting FlySky? It seemed like the test showed FlySky was way faster than FrSky. Did I miss something?

[@bennieleip579]

Dave Lendl because if iam correct he said that they can fix the problem but not for the people ,that they can make another product so you have to buy that (if i remember it correct, but i dont think iam letterly correct😆)

[@nadau5027]

Cool

[@propabilityfpv303]

hahahaha i love this, im still using my flysky with my 40A hypetrain build! ima wait till someone makese a radio that can beat the latency of the bottom of the line radio to spend my hard earned money xDDDDD i get money from phone screen replacements on the street and thats not much cuz i only charge $35 for a iphone screen replacement. soooo when someone can get their shit together ill be waiting lol

[@69fox]

Average latency on Horus should be 37 seconds, not 31.

[@diy-dash6103]

Dont cut the red wire arrrrrrhhhhhhh!!!!!!!!! 😬

[@DroneMesh]

Trystan XD

[@joel_fpv]

Call trappy and ask for a cross fire

[@BuzZ.]

Pop the top off bro, just pop the top off :D

[@martykracher]

I guess I'll play the "First" Game! FIRST!!!

[@benbilbao7116]

This is dumb, you could've just depinned the plug and connect that to your breadboard, rather than cutting the wire, this guys has no presentation skills at all. Why dont you start the video actually explaining what you are testing. What parameter were used, what firmware/software and receiver tested etc kind of a waste of time watching this.

[@MisterJDee]

Don't waste your time fixing someone's shit product. FrSKY is Shit. It always has been. The community has been fixing (aka modding) FrSky from the beginning. The only thing that Frsky has going for it is that it has small receivers. If you want to spend your energy doing something, create a micro receiver for the flysky protocol and sell it. You will sell millions! That's all we need... micro receivers for Flysky. The guys at FrSky are laughing at how stupid we are to keep buying their junk.

[@renzevenir4853]

Then why almost every people I met use Taranis? Simple, because it's one of the best transmitter. Flysky need to step up their game. Listen to the community and create the perfect radio. Even the most expensive Flysky transmitter (FS-i10) doesn't has magnetic gimbal and openTX.

[@MisterJDee]

I bought 2 taranis radios from different sellers and both died. So ghost power switch problem. I went to the community, couldn't help, went to FRsky, couldn't help, went to the reseller, couldn't help. So I threw them both in the bin where they belong.

[@renzevenir4853]

Just because you got bad products, doesn't means that all of them are bad. If all Taranises are as bad as you described, it won't hit the market.

[@renzevenir4853]

What radio are you using?

[@MisterJDee]

IRFZ44 true, I just got bad items. I'm just pissed off cause I'm waiting for a decent product to be released and they keep making shit for us to buy. I'm using the Turnigy Evolution right now and apart from the lack of micro receivers available I love it. It has USB charging, small form factor a great cover for protecting gimbals when you throw it in you bag. I'm a pincher and I think it's awesome. I also have a Radiolink at9 and just bought a bunch of micro receivers for it. Don't love the form factor or the battery situation but it's much cheaper than Taranis and supposed to have a lower latency protocol. And for my TBS crossfire setup I have the Turnigy 9xr. Love the radio, but it's too fucking big. The quality of the gimbals and the switches are a million times better than the Taranis. Also much much cheaper.

[@pressalltheknobs3277]

While I don't doubt your results measured whatever it is you measured, your video is highly suspect because it spends forever showing us how you created a switch and then it presents some charts. At no time do you explain or show what you actually measured or illustrate how you ensured that these results are comparable. This makes your results unconvincing and useless. Please explain your actual method!

[@DroneMesh]

+press all the knobs check the playlist you will see

[@DroneMesh]

+press all the knobs override gimbals through switch to capture consistent reading once the switch is turned on simulating full throttle it captures the signal coming out of the receiver and the gimbals input to see how long it took to register on the receiver

[@pressalltheknobs3277]

So I guess you used a scope to see the switch and the SBUS output of the receiver simultaneously? That is what you should show. What are you comparing on the FlySky? It only takes a few sentences to explain. This is a 15 minute video! Instead we get 7 minutes of you making a switch which tells us nothing. By the way I left a comment on your 2nd X7 D16 video, explaining why the SBUS packet are the way they are....your speculations are incorrect. Also as far as I can tell you never actually tested to see if D16 in 8 channel mode can send new data every packet. kzbin.info/www/bejne/hmSyemmCgtl5bMU&list=PLoPtpxJIxgnYygWkklJgMPpFzh66Na1xf This is all well known stuff if you look around a bit. In my view you should take both those videos down and redo the test properly. The first video is just an ill conceived test based on bad assumptions and proved nothing despite your claim of "myth busted" and the second only demonstrates the D16 16CH half of what you claim to be testing and does not test the D16 8CH half.

[@antoinerivoire]

press all the knobs the methodology is explained in a previous video. Just look at the other latency videos.

[@pressalltheknobs3277]

Possibly it is but that is not the point. As I noted above, the methodology and conclusion of the other two videos I watched here are nonsense and inconclusive respectively so if Mr Drone Mesh is going to make claims he really needs to be a bit more rigorous.
