FPV - Long Range System (LRS) Shootout | Flite Test 

Many thanks for the provocative series of tests. And despite any shortcomings, we should compliment FliteTest and Alex for stepping forward and giving it their best shot within real world time constraints. As a microwave technician, I appreciate all the complexities planning and conducting tests like these with limited resources. The fact that you encourage dialog on RU-vid and your website is a testimonial that you encourage open communications. Kudos gentlemen and keep 'em coming!

That was a lot of work! Thanks ibcrazy and FT for the show.

YOU GUYS JUST ROCK! We need muuuch more videos like this one to clear up the FPV options out there! Thank you!

Great review! Thank you for not dumbing this down and keeping all the technical goodies in the edit.

One of your BEST guests and certainly an excellent topic to cover. Makes me feel good about all my EZ UHF gear. I have always used the diversity Rx but feel confident to try a Lite one next time.

could you setup towers in a feld and use them as repeater? for example setting up your base station in one corner then sending three towers out in each corner or the field you would be flying in or covering? or if your license to set it up on a different frequency or some sort of point to point with tracking?

Amazing to see the enthusiasm Alex shows when he is explaining what he did etc. great episode guys!

lol at 12:44 it looks like the guest suddenly had david's voice.

Very nicely done. It's nice seeing how enthusiastic Alex is about what he is doing. It would be nice to see a comparison between popular OSD systems. Thank you guys.

I love how passionate IBcrazy is about the hobby... Gets me pumped!

Great video, I've been waiting for someone to do a test like this for ages. Thank you!

Awesome guys you killed it with this one! good job! Answered SO MANY of my questions!

Awesome! Thanks for taking to time to review and inform everyone.

I would like to add, while taking your antennae off of your receiver makes a good test, never take the antennae off of a transmitter and try to broadcast. It can potentially cause permanent damage to the transmitter.

love the production value on this. keep it up guys.

the most interresting fpv video i have seen in the last time. Thank you alex, i like your knowledge and your enthusiasm. thx chad, josh, josh, the swedish guy and the others that helps flitetest going!

Really cool having IBCrazy drop in!!! Show us a full LR setup please.

Great video! I've been watching it for years,,,, In fact, Its been over two years and the OpenLRS shown in the video has not been available for almost that long. Hawkeye systems are not easy to find either making me skeptical of using one. People that have used them said they had to remove the system fairly often to update software and did not like that aspect. I wonder if things have settled down over time? I'm really interested in using OenLRS but quick update would be helpful.

Josh, Alex, and David: Thank you for an interesting, useful, and entertaining shootout! Much appreciated.

Wasn't expecting this video, great job guys, flitetest and ibc = great info!

Great video - and the fun is contagious!

Another GREAT VID.. @Alex ty, yet again you have helped me soo much with your videos. (u 2 flight test) You might not know it but UBINSOERATIONAL homie lol. and sometimes make a guy with very little moneys, feel like a king. And Saving some of us from wasting money... (I thought dragon link was the "only" way to go) sooooo thankful for not only the test but what you reiterate about how little power we actually need to fly... compared to what's on the market, most of us thought 600 megawatts was needed to fly ur mini at first... yes noobs like me, but Ive still see a lot of people thinking the same way I was, until educated... I know now that even my 200mw transmitters are MORE than enough for my fpv mini quad purposes as I very rarely go more than a quarter mile away with a mini at least... But im pulling off my 600 vtx from the 450 because it's simply overpowered. Running a pixhawk I can't have any interference. Shared and shared again... Also very appreciated once again! Ty Alex, Joe + flight test crew. Please keep um coming! And please print shirts that say. "everything I need to know, I learned from flight test!" I need a XL! 😆

Awesome to see the three of you guys in a cool video!

Flite Test & IBeCrazy... How much cooler can it get?

PLEASE bring iBcrazy back more often. His RF kung-fu is strong (I am saying this as someone pretty savvy with RF for ~ 20 years), and I appreciate the diversity (no pun intended) that he brings to the content. In fewer than 25 minutes, he has answered so many questions I had regarding RC & FPV given the myriad of options on the market.

great vid guys cool to see ib crazy on here your show has really become a place for all parts of this hobby to share there knowledge thanks guys for the great entertainment

This is the best video yet. Let me just say you are the RU-vid channel I watch most, besides Davids and RCmodeler reviews. You prove to be the best of RU-vid!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and should be pumped into MY COMCAST!

This is a very good episode, iBcrazy and Flite Test together!!!!

Alex is so passionate about what he does he's crazy, nice video guys and very informative

*Help me out!* So i'm new to FPV Plane flying for long range and I did lots of research to completely know what I need for a good and safe flight (over 2km) what I need is: 1. Video Camera (connects to VTX) 2. VTX and Antenna (Omni/Leaf) (200mw 2,4Ghz) 3. Video Receiver (Connects to Goggles/Screen) 4. UHF (433mHz) Transmitter (Binds with TX Trainer Port) 5. UHF Receiver. (Servo plugs) 6. OSD Is this correct and do I need anything else for a good and safe flight for over 2km?

Thanks guys, this video disintegrated a lot of my tension! Keep it flying!

I love the way he is so expressive with his voice and hand jestures. Awesome

Great episode guys... love Flitetest and IBcrazy

hey guys great videos, always very helpful reviews and tips and tricks; for these long flights on a 250 quad, what battery do you suggest; like how big should i go: battery size? thanks in advance.

You were saying something about "return to home" settings for quad copters. Does that literally mean that it starts flying back where it came from when it loses signal? I am just starting to learn about RC flight and I can not wait to get started. Now just to find the funding.

this is exactly what i dreamt flitetest would make a video about, it has everything, Ibcrazy , dragonlink, uhf stuff and info !!!

The most explanatory episode ever thanks guys

Hope there's more footage with Alex, would love to see you guys just flying with him and enjoying yourselves

Great show guys. This just affirms how much I need to learn still. [goes to forum to look now]

great info, was hoping flitetest would do an episode in UHF stuff , ty ibcrazy

Great job guy's, and it was nice to see Alex (IBCrazy) on the show.

That LRS helmet is so rad with all the RC gear :D

Great show and clip at the end!

@FliteTest could you all do a new LRS with the new updated systems or with the latest update in the same systems tested?

There is more accumulated knowledge and information from this site than any other. Keep it up guys.

I'm not sure if using attenuators would be an accurate measurement of distance because the attenuators are lowering the note the noise floor along with the signal so I'll sensitive receiver would still be able to read a clean signal whereas that same receiver may not be able to read a faint signal through a high noise floor

Thanks for the information! One question, can't you damage your transmitter by taking off the antenna while its on?

What kind of filter to use on Orange Open LRS 100mW/1W transmitter to avoid interference and cut of the 1.2 GHz video, please?

You guys should learn about SWR and how it can fry your transmitter if you use it without an antenna for too long. Also look into RF exposure before putting transmitters on your head...

One of your best episodes...

Great episode. Can you guys do a similar one: test the different types of antennas? A video about the different video systems and video antennas would be epic.

the guy was so happy and energetic, and Davids just like wow....that's pretty cool......

Wow, that Alex guy is super awesome. So enthusiastic and helpful!

FPV super stars! awesome vid guys!

is it possible to view footage from a dslr thru the dragonlink while youre recording or do you need a seperate camera?

We would love to see more videos about fpv systems from Alex, and a long range flight done by the flight test crew!

Wow, this is a great video! Lots of good information.

this episode was helpful but i was wondering if you guys could do more of a tutorial. keep up the good work!

ATV repeaters are actually transmit/receivers operated by ham radio operators. It's amateur television transmitted between individuals. They operate in a variety of frequencies and a bands. Popular wavelengths are 70cm and 23 cm and sometimes shorter. The gentleman in the middle sounds like he was in fact a ham radio op, and probably a very skilled one.

So if I have an 800mW 1.3 system and I don't want to overpower an OpenLRS, would an attenuator help? If so what dB is optimal?

Definitely a lot of information (having watched original video already, it's a nice summary)

how do you increase the range of your controller? Or will it perform at these distances regardless(quadcopter) I have a gemini, I want to know if I can upgrade these parts, and start some long range FPV/some more penetration. Or if I broadcasted controls on 2.4, and video on 1.3. Would I get 1-2km's? Not looking for much, I just want to know the potential of the system. Know what I mean?

Great video, quick question.... but if we run video at 5.8ghz then the issues that dragonlink had wouldn't be a problem right?

Wow that dude is fired up. I have no idea what you're talking about there but it's still entertaining for some weird reason.

Loved it, extremely helpful. Thanks guys!

Excellent! Plz build on that type of info. The only thing that's keeping me from pulling the trigger is the fear of buying the wrong stuff!

Nice one Guys . . worth the wait :)

It would be so cool if you and alex did an episode about the specter, I'm sure every one would love it.

Awesome, just what i needed. Thank You !

Awesome tests, great to Ssee Alex on here :-)

You guys helped a lot thank you!

Can you have a unit flying a certain distance away from you act as a relay for a plane flying really far away from you...acting as a bridge almost? How far could you get?

Awesome. What firmware were you running on the OpenLRS? I have been mucking about with OpenLRSng. Big difference from the standard firmware. Love it.

i have a question, if you fly most of the time be twine 0.5 and 1 mile do you need a UHF transmitter can't you just use your spectrum/JR/futaba....transmitter wit full range RX?

Thanks for the test . That answered a lot of questions for me . Saving money is good but if you save $100 on radio/video and loose your plane what have you saved ?

Can someone help? I'm really confused. I thought UHF only transmitted signals for your aircraft's receiver. In this video is it transmitting only video or is it transmitting video and aircraft controls? If I want to do fpv do I only need a UHF and not a separate video transmitter/receiver?

Awesome guys! Very helpful.Keep up the good work :)

What happened to the FT3D speed build kit and all the updates that were supposedly made to it??? Been waiting patiently for this to come out!

Do the lrs systems have the same general connections to the remotes? (Plus, ground, and signal)

So if staying close by is most fun would a DX7s work fine for most FPV flying? I guess I have taken some planes out pretty far LOS with it but still not sure of the actual range of it.

EXCELLENT comparison! Great idea to bring Alex on for this one! Is it safe to assume that 5.8 video is a non-issue with ALL these LRS systems then, as it seems the focus here was interference with 1.2 video...?

Alex just made the 50 shades of LRS. Beating and punishing these systems. So enthusiastic about it too!

Great episode.

I had the Fatshark predator goggles and just started to use my Sony HMZ-T1 3D viewer goggles for FPV. Amazing !!

Are all of these products shown only for control signal, or do they also have video?

Agree with the comment about using a very old Scherrer LRS. also power settings were not discussed. Many transmitters have the ability to boost signal by upping the power. Having said that a great video and IBCrazy is a great personality and contributor to the FOV world.

You guys are the best! You guys now have more subscribers than rcpowers congrats!

what are the LCD screens are shown on the tripods during the tests. Looking to get one.

Is this 1000mW or 100mW version of Flytron Open LRS transmitter?

Great video and thanks to IP crazy for those tests, this is great work and very easy to understand for someone like me that know very little, this is great work!. The only thing i wish you guys talked about is the penetration aspect of those system. It seam like a lot of people will choose uhf for the penetration it have through other objects (compare to other that don't have much penetration) like trees or wall, am i right?

I'm confused with them using a servo for testing. Were they also testing control signals and not just FPV video signal?

love your system, its all about knowledge on how rf are affected with harmonics, de-sensed, and how to propagate the signals.As long as you know placement of transceivers including chosen of bands, you get much of the range out of your system. Well. best systems will have a good front end filter to fight de-sensing - (reduction in sensitivity in the front end through high RF bombardment) and good filters on transmitters for clean Emitted RF. even though you have all these, if you don't handle RF propagation well, you will not maximize the range.

Love your guest flitetest! Who is the NYC flying guy?

Can you guys used ez uhf set up and go as far and back????

Great review! My Chainlink is what Rangelink evolved from and when I added Alex's turnstile my range doubled or tripled over stock uhf dipole. 5*

Could an older television set with the UHF channels some how tune into a FPV transmission?

Hello I have been looking in to rc booster and I and not find a booster that boost the signal from 1 booster to anuther booster and then to the rc car do thay do then or am I not looking for the right thing

How much effect does cell towers have on quad radios and FPV systems? (sorry if this has been asked before) ...If there is a source of info please provide the link. Thank you so much.

How can u not trust ppl who doing their job with the passion ! TBS I admire U! Great video!

Do these systems have "channels" or are they spread spectrum and no need for frequency flags if you are flying with other FPVrs?
