@@CurryKitten We appreciate what you do! And we certainly prefer getting asked questions and get the right info out, than correct the wrong info that's already out.
Even I was nervous as you headed out over the water, I don't know if I'll ever not be worried doing that! +1 for deadbyte love, an absolute superstar. We originally used RSSI dBm for Dynamic Power, but it wasn't very reliable for detecting the actual receiver conditions so we switched it to SNR (for 3.0 or was it 2.0?) and have had much greater success. It will also up the power based on LQ or missed telemetry, but RSSI isn't used at all any more except for FLRC as you mentioned.
Wayne, just got through having a cuppa Guatemalan coffee, looking at picking up more branches around the house deposited from the lovely hurricane and took a break to watch this video you’ve posted and I have to say it is extremely informative. I’ve been following your recommendations recently on a range issue. And of course as you know where I’m flying is a little sketchy to be doing this with fear of losing it in this environment. And I was getting nervous with the DBM dropping off, which we also found out was a broken antenna wire. But the demo from the person in the Philippines and your current experience hopefully my heart rate won’t go as high as it has been. But again, I really enjoyed this post, very informative. 😊😊😊
I've got 5km no issues with a 800mW vtx - that'd be mostly over water at about 50m reaching a max of 300m. I'd recommend higher antenna's, if you look at Rebel Ruxus images on a google search I feel that's a good starting point, I have my Rx vertical out of the GoPro and the vtx I've raised about 20mm higher than the top plate., battery is a 6500mah Lipo so no need for Li-on. Happy to send some images of my setup and the stl if you want to try them.
The concept of "haw far can I go on xxx power" is always a tricky one, as it depends an awful lot on the area. I've flown over 6km on the old ImmersionRC 600mw units. The only thing I wanted to show in this video was - hey there's snow at 1W, so lets see if it's clear on 5W - which it was. The fact that I might expect to fly further on less on a different VTX, or a different area matters less for this particular demo. I would agree about having vertically polarized antenna would really help - I always find this tricky in a quad, but I might do some mire stuff with this to push a little further so may well look at this config. Cheers :)
It's been a useful quad - I've mostly used it for when I got a component into review, so cameras and VTXs have been swapped out a lot. It's a shame the frame wasn't a bit longer so you could easily fit an HD system in it as well - but it flies pretty well
@@CurryKitten so apparently its not been coded yet but the one dev said they could do it. Supposed to reduce multupathing. Keen to try it but I agree it could be detrimental.
video antennas: get rid of any pigtails and adapters. the antenna should be connected directly to the VTX. that makes a big diffenrence, at least in my experience.
They certainly can effect things. Some VTXs have an MMCX on them, so there's no choice. Decent manufacturers should take this into account with their designs
@@CurryKitten I'm using a TrueRC long pin with MMCX one the long range kwad and a floppy flex cable antenna with MMCX on the freestyle build. Both supported by custom TPU legs on the standoffs. Nothing in between. No losses. Works very well. Pig tails and adapters gave me way worse results all the time. I'll never go back.
All I use is LQ. Not a fan of having tons of numbers jumping around and scaring me mid flight when LQ is constantly at 100. A bit odd that breakup at 2.3km…1W with good antennas and LOS should easily be able to get ya at LEAST 5km.
Your flying on Crossfire aren't you, so you have a certain dynamic speed level, so 3:100, 2:100 down to 1:100... something like that? I agree that in most circumstances 1W is plenty to get to 5km, but it can always depend. In that particular area we've had video go out on 2 planes completely and rx failure (yay for RTH) so it can get weird there.
@@CurryKitten in my OSD all I see is crossfire LQ as a value from 0-100 without any additional : or numbers actually. That is odd about those scenarios. There must be some level of RFI in the area then!
I used the one they supplied (which will not work with anything) and then replaced all the known bands with the regular values. So I sort of customized it.
There's an OSD bit for it in Betaflight, but just make sure you read the ELRS notes about what you need to do. I forget exactly what that is, but it's not all modes
5 watts you better get it flying within 10 seeconds over major overheat and your battery life from 30 minutes down to 5 minutes better have a seperate power supply for the thing a 10 amp pack
The cooling fan actually works very well. Also, I have it set to low power disarm, so when it's sitting there waiting for sats the VTX is running at 25mw. Compared to the amount of amps a quad uses to stay in the air, running a 5w is fairly trivial
Those arms feel solid. Generally above 7" there's an amount of resonance where the arms will move. Just see my recent review of a 10" quad to see this in action. The 7" at least feels smooth to fly
Thanks for the love! Happy to be of some help.
And thank you for helping explain what those numbers represent or mean.
No worries - thanks for all your help. I must have asked questions for most of my videos involving new things in ELRS!

Thanks for extra info on this - very useful. Glad it's not just me that gets shaky legs over water :D
Absolutely brilliant content. Pushing it further 👍

As always great video mate, your always the one I've looked up too since I can back tj fpv a few years back
Thanks muchly :)
Great info, Wayne! Thanks a bunch! 😃
Great flying as always!
Stay safe there with your family! 🖖😊
Cheers MC - hope is all good with you!
This is all great info! Thanks! I too would keep an eye on my DBM RSSI and I have it set to -98. I was told to mostly pay attention to your LQ. Cheers
That's probably the easiest thing to do. I'm going to up my alarm to at least -102 so hopefully I can stop fixating on it :D
Very interesting and informative video. Thanks for sharing. 😎
My pleasure!
Nice VTX!
Cheers :)
Useful video Wayne! I know the shakes from long range :)
It's definitely the range and not the age :D
Your rssi dbm isn't even close to failsafe in the 90s. Only worry if it's Around -106. Even then your fine if the lq is good.
Well yeah. I know that now, so I go in much more confident for the next range flight

I see you use your tyro 129..i have one of them and i went and got it after watching your review on it.
still use it to this day as well.

Glad it was helpful!
With Tbs Fusion and Elrs you can now do dynamic vtx power
Handy maybe. I don't know if I want my VTX power changing during flight though
@@CurryKitten so apparently its not been coded yet but the one dev said they could do it. Supposed to reduce multupathing. Keen to try it but I agree it could be detrimental.
Personally when i ever fly long range i find its all about antenna! The end.
Pretty much - sensitivity and position of rx will often trump raaw power

Can you please let me know which VTX table you used. I purchased this VTX and I’m having a hard time finding it.
I used the one they supplied (which will not work with anything) and then replaced all the known bands with the regular values. So I sort of customized it.
@@CurryKitten okay so should I use smart audio 2.1 vtx table?
damn when did you do this video ? , weather is awful right now ( atleast where i am (south england))
I am in the south of england as well. If you remember a week or two ago there was one reasonable day and rain either side of it. Out I went !!
Does anyone know when the alpha 16 16w vtx will be for sale? I saw it on the website and then I tried to buy a few days ago and it was taken down.
How do you get the rf Mw power from the radio
There's an OSD bit for it in Betaflight, but just make sure you read the ELRS notes about what you need to do. I forget exactly what that is, but it's not all modes
You do seem to struggle with wings though!
You would not believe what the failure was on this one. So annoying and simple to fix. I'll explain all when I finally fly the sodding thing
-108dBM for 250hz... ELRS has the min dbm in the menu. I have my alarm set for -100.
I'm upping mine to -102 now
5 watts you better get it flying within 10 seeconds over major overheat and your battery life from 30 minutes down to 5 minutes better have a seperate power supply for the thing a 10 amp pack
The cooling fan actually works very well. Also, I have it set to low power disarm, so when it's sitting there waiting for sats the VTX is running at 25mw. Compared to the amount of amps a quad uses to stay in the air, running a 5w is fairly trivial
zip tie an empty 1 L water bottle, w note inside
Even with a bottle, if it hits that mid it's sinking down :D
Those arms are wobbling a bit :(
Those arms feel solid. Generally above 7" there's an amount of resonance where the arms will move. Just see my recent review of a 10" quad to see this in action. The 7" at least feels smooth to fly
@@CurryKitten I also got 2 Chimeras 7" and I didn't saw that but on my 9 " is clearly visible :D
