Crossfire vs ELRS 915MHz would be fairer and makes more sense, compare the ability to reject noise besides range and penetration would be good as well. Thanks JB and Blunty for your nice work! 🙏
Best to compare crossfire to 900mhz elrs really as it is the same frequency range, 2.4 is best comparable to the likes of sbus, it just proves how powerfull the digital elrs rx's are compared to the older stuff we used, in my eyes modern tx links are moving on up fast :)
Rc should always outrun video. If your video outruns your RC you’re screwing up. What we need is a video that compares RC vs video at each MW of power and hz. That way it’s basically like “if running 1000mw DJI, do not run your elrs 2.4ghz module less than Xmw when at Yhz”
in theory you should be able to set your vtx power levels to a switch, and then as you test your rc link at different powers you can cycle through the vtx powers and see what drops off before, essentially soft fail safe
@@propphotographyaz9992 lol I’d just use math since there are antenna power/distance calculators online, but if you don’t want to do that: I’d find a location to place my quad that is behind a lot of objects/in a basement etc, where video signal barely gets through at 1000mw and walking away or turning around loses signal completely. Then I would mark that location and gradually adjust my TX until it failsafes. Every time it fails while the video does not, I would write those values down as minimum values at Xhz and Ymw.
I have been running 2.4 since spectrum was just a jr module on existing radios there is no way 2.4 gets all the way around my block at ground level no matter power packet rate antenna no combo makes it but 915 consistently at ground level elrs 2.4 is great but 915hz is on a different level mr Bardwell try 2.4 vrs 915 at ground level and you will see a very clear winner
If you're in a HIGH RF, Interference area radio control systems will fail no matter how good they are. You have to remember there are thousands of devices transmitting on those 900mhz and 2.4ghz bands all the time. Even the electricity flowing into your home is going through a meter that transmits information over 900mhz. So if each house, phone, radio, TV, electronic appliance is using the band in a crowded neighborhood, failsafes are always possible. Hope this information helps. It helped me when I heard it. I now carry 900 and a 2.4 quad so wherever I happen to be I have a quad that will fly without failsafes due to RF Interference.
I had a ton of trouble with range with Crossfire in Philadelphia, Loads of interference, sometimes I couldn't fly to the other end of a park without a fail safe on 1w. Get close to a hospital, instant failsafe
I was watching FinalFlideAUS an old Rotor Riot pilot from the early days of FPV and he touched on this topic. I also had trouble with 900Mhz ELRS failsafing in metro area, less than 300 meters. He stated that which frequency you use depends on where you're flying. In cities that use 900Mhz for a lot of utilities and communications, use 2.4Ghz because the 900Mhz band is small and easily crowded in city areas. 2.4Ghz in a city would be better at having fewer failsafes due to RF Interference. 900Mhz would be best in rural areas with less RF interference.
Been runing elrs since almost its start.. I havent had any fail safe or any type of issuds w it... Previous to that i was runing xfire.. Zero complaints on neither
@@paulhope3401 I haven't had many fail-safes but it runs almost exclusively in 50hz mode because the link can't keep up with 150hz. So it ends up feeling pretty bad, not to mention that they have fixed bugs in updates then literally unfixed their mistakes in the next update. I had an issue with my xfire module not regaining telemetry after loosing it without power cycling. They fixed it in an update then the next time I updated they brought the issue back. And that is the second time they have done that as well I have had other bugs unfixed

I love this Channel, it answers so many questions I had in the past and forgot about
Don't forget there's also 915MHz ELRS
Yes!!!!!!
Try to buy it now. Out of 4 producers there is only Happy Model now 😭
@@MyAeroMove ones enough(well wish there was more prebuilt), I installed it on my R9
@@MyAeroMove actually no, there are some less known brands (nonames) that produce 900mhz elrs receivers. I use them no problem
@@MyAeroMove check out the gorilla link ELRS900

Woo woo woo! 150 crsf vs 150 elrs ... elrs wins? Link it in the description.... I want to learn something today!
Pretty interesting indeed.
I wish a reputable manufacturer like radio master would make a 900Mhz ELRS module that can go up to 1W
Thank you sir 💖

And... Where does ELRS 900 fall these days? Any valid modules for that?

Namimno is probably the most reliable. Sadly no diversity receivers are out yet, that’s keeping me from getting involved.
I use a 900 namimno module, it's done me solid for over 2 years now no problems as of yet 👌👍
im using r9m(4 years old) and diy rx no problems
There is JHEMCU 900 receivers on Ali. Only caveat is the antenna for 2.4. But even with wrong antenna it's still ok for whoops and similar

Sounds like it's not setup correctly. I'd guess youre on 868 instead of 915.

curious, you go over 50 hrz and 150 hrz independantly, but what about crossfire on dynamic? and for that matter, should dynamic even be used?
Crossfire performs best on dynamic, should be used for bandos, but not for true long range..for LR lock 50hz
@@Fly_High_FPV thanks a bunch!
Some areas in my town/city blast 2.4ghz wifi for town/city wide wifi. Feel like my video also gets interference
I can outrun my buddy's tango 2 with my zorro both of 150hz and 250mw
One more time - what is the best setup for LR flight - ELRS with low package, right ?
Yup, also as JB said 900 MHz is even better
ELRS915 1000mW 25hz goes all day. 😳
How should we setup crossfire in Australia for max range and penetration? Tango 2
Leave it on dynamic power and dynamic packet rate 👍
Who would win in the scenario crossfire 50hz vs Express lrs 25hz?
Have you tried taking ELRS down to 25hz?
Does anyone know any good places to fly in San Francisco??
Don’t the city have several abandoned buildings? I have seen Some Bay Area FPV guys posting video flying around some abandoned building in SF.
@@GTRFPV Im 16 years old so i cant really look around by myself. Do you know where i could see those videos or ask those people where they fly?
Dji v2 remote for o3 and updated vista is great contender..
absolutely not, if you lose video, even just briefly , the rc link doesn't recover until after several seconds. watch Ian's (mads tech) video on this.
I’m reluctant to get the v2 controller because of the small gimbals. Did you have to adjust your rate for the smaller gimbal? Thx.
CRSF > ELRS
This
you're simply talking BS, giving misinformation
First time ive ever heard someone ask if they should get rid of proven crossfire perfection and switch to some elrs garbage. Lol millennials
I rate my Xfire but what's garbage about ELRS?
As a user of crossfire, crossfire is just not good.
@Generic fpv Other than the higher price Xfire has performed excellently.. never had one issue or failsafe since day 1.
What's bad about it?
