TBS Crossfire - 100km RANGE TEST - UHF CONTROL LINK 

Team BlackSheep Dude, did you guys actually recover the aircraft, or did you just punch it and let the lipo explode? 18,000mAh consumed, what's left for the return trip?

Team BlackSheep I have just gone to buy this from your site and it says its pre-order at the minute, Do you have and approx time scale for deliveries to uk? Thanks

***** the tbs unify 800mw, tbs groundstation with 24dBi grid antenna, tbs core pro. Please check video description

Team BlackSheep Make a commercial for quadrocopters and obstacles. Or ground test various capacities at a maximum distance.

Need a very good helical

Probably a 1ghz video setup

Its in the description. 2.4ghz grid array antenna.

+Radi0he4d1 - haha good stuff man.

Now it's not joke anymore

whats your setup if its not a secret?

+Marko Srepfler - I happily handed TBS my credit card and said take it all...haha.

TheYowzerr if you find yourself an elevated position you are going to get even further than with 433 MHz LRS due to the fresnel zone being lower. During developments we have walked 600m here in a rural area through woods and neighborhoods without losing the signal, obviously RX located around 1m above ground. It will be worse with the VRx so close to the ground ... BUT ... you just need to match the video range and that will be gone way before then :)

ahh ok thanks, so hopefully I will be ordering my crossfire soon instead of dragonlink or ezuhf

eric deherrera no they drove and picked it up. There is a beacon on the UHF receiver that broadcasts the GPS signals, so they just drove into the general area as indicated from the GPS coordinates on the fpv recording, and then homed in on the signal with the Crossfire.

I'm sold!

We'll find a way to get that added

they use super dupper secret pico fusion batterry :)

It has its very own flux capacitor.

***** just 30km into the return trip the batteries were finished. and we landed in a field to pick it up.

Zachary Buendia thanks bro!

+DIYRCPilot just in between UMTS bands actually. the Crossfire operates in the SRD band (Short Range Devices), with sufficient sensitivity and self-healing link tech to become a long range device ;)

2.4 unify 800mW, tbs groundstation, 24db l-com grid antenna, tbs core pro

But, the 100km are video limit not RC control..right?

@@mattia452 да

whats the update? coz afaik both r9m and tbs crossfire have same specs in you case the problem is noise probably

This IS a real world test. It's not TBS fault that the ezuhf JR module only does 150mw. I haven't had my discovery much past a mile out yet but even then the crossfire hasn't been above 10mw of power with a constant 100% link quality. This system is legit and FULL of awesome features.

Radio waves bounce up and down from the earth and the stratosphere until it hits the RX

Whoops wrong comment

Highly doubt it unless using a antenna tracker and a many turn helical or Yagi or somethimg.

It was a l-com grid array antenna. And the 800mw 2.4ghz did as you see in the video.

+rajeevpandrangi It doesn't..

That doesn't make any sense breezyjr

It doesn't compare, because the DragonLink won't go 100Km, doesn't have the self healing connection, and many other functions... So, what doesn't make sense??? the two don't even compare...

self healing connection? breezyjr

+rajeevpandrangi That's what Trappy calls it... Basically, from what I understand, if it detects any type of "problem" it will change to a different channel... I'm not entirely sure, to be honest... I've just heard Trappy describe it that way...

and another question, wath us better; stock antenna or tuned for crossfire ?

I'm curious too, somebody?

Depends on the system. I've personally done a ground range test of Rlink/MFDLink (which I think may have been the first LRS to use LoRa) out to 100km with 1W of Tx power and omni antennas on both ends (whip on Tx, dipole on Rx). Had a solid link as long as LoS was maintained. Folks have flown various 433Mhz UHF systems out over 160km. The other issue is that not all control frequencies play nice with long range video frequencies. 1.3Ghz is the undisputed king of long range video, but it often steps on 2.4Ghz control systems, or is stepped on *by* 900Mhz control systems. This system claims it is "unaffected by local noise" but that would generally defy the laws of physics. LoRa can listen below the noise floor, but that makes it resistant, not immune to local noise sources. FWIW, almost nobody really needs 100km of range. What you really want in a good LRS is the ability to fly through the nulls of the antennas, behind your back, and occasionally out of or below LoS while maintaining control. In other words, the control link should *never* drop before the video link, and you should be able to tell your aircraft to do something like turn and climb while flying blind behind a mountain (something I've done many times with Rlink, even 10-15km out).

Full size crossfire and corepro with tbs gps.

2-3 weeks

This comment aged well. 2 weeks. Lol

Brian Mabbett I came to a similar conclusion... at a distance of 100 km an object HAS TO be at least 784 meters high, to be (barely) visible behind the horizon. Strange...

That's not All ships have reported seeing Light House's at over 42 Miles (68 K) when it should be 1'176 Ft (726 M) below there horizon ? Me thinks we are being lied to. .

Brian Mabbett Seriously... Seriously. Another Flat Earth certified wacko.

Justin Saneti you tell me how then ?

Brian Mabbett That's why they take off from a mountain ! ;)

Lol

Some laws may change. Others will remain.

+Andrew Smart - I agree. Simply mind boggling.

+RCFox - Same here man. I threw my credit card at TBS.

Was IRC UHF really that bad, compared to the TBS prices?

Martin Demin obviously you don't fly....come one man they aren't hurting anyone ....people like you kill me

1W ... in the wilderness? please?
