This Antenna POOPS All Over Crossfire | FPVCycle/TBS Minimortal T Review
Vložit
- čas přidán 3. 02. 2023
- My biggest challenge with crossfire is the size of the antenna and the difficulty in fitting it into smaller builds. When I saw the Minimortal T, I thought this could be the perfect solution. I know that TBS really tries to manage expectations with this antenna but I thought, how bad could it really be... Right?!?

Great Video comparing the Imortal T to the miniImortal T antenna. I had / have similar results with the miniImortal T. Glad it was not just me, was thinking maybe I got 2 bad ones 😆(Got 2 tried both and same results) I only use it on my freestyle 3" and under quads. I do not even use them for my cinewhoops. Great review / video Mangorille!!!!!
Thanks buddy, not just you! :)
Great topic! I built five 5-inch quads with Immortal t's, and then I built a 3in Digi-toothpick and used the RVS Tiny Tee antenna, which is just a small 900 MHz PCB antenna. After flying it all last summer, I realized that at the same output power I wasn't getting anywhere close to losing range in the area that I do freestyle, SO.. I just built another 5 in this winter, and I'm experimenting with the VAS Pro LR Crossfire antenna, which is basically a printed traversing circuit sandwiched between credit card material. It is a rectangle about 2.5 x 3/4 of an inch, and only weighs a few grams. It's flexible, and I've got it sticking out the rear, sandwiched underneath the back standoffs between the rear arms out the back. So it should get pretty decent coverage around the frame. Basically, the same place as most of my other Immortal t's are placed. It also looks really slick. I built the lightest quad that I've built so far, at 660g all up with a session 5 and a 1300 6s tattu. I know that's not the lightest in the world, but I still have TPU prints (armguards, cap/tvs holder, session mount, etc..), led racewire, a decent-sized video antenna, 2506.2 motors, and Vista with OG cam. I hope it works, but if it doesn't, I do have an immortal t and some prints that I can swap out. And now we wait for spring..lol.
Great channel, I've been subbed for a while and I'm really enjoying the content. Keep it up! 🙌
Well put, ultimately the best antenna is the one that is the smallest and easiest to use for the conditions you fly in. I'm not a long range pilot so as long as I can fly behind a building and some trees with a bit of margin, I'm happy. I don't think this particular antenna fits that need for me though, it was really struggling on the way back at 250mw in an open field. :) Glad you're enjoying the channel!
@@Mangorille oh I hear that, I walk long distances over terrible terrain through all types of weather for a living...my motto is "I don't fly farther than I'm willing to walk if I crash".. 😅
Cheers man! 👊🏻
@@willpowerfpv3246 Haha, yup!
I have converted my EMAX TinyHawk II to CRSF and use this small antenna. Works like a charm. Not doing 40 km LR flights, though 🙂
Good use case for these antenna and really what they were meant for.
The centre mounting of the antenna, or on the bottom of the arm is literally the worst place to put it. The carbon blocks all the signal depending on the quads orientation, especially when you are flying it and it passes in front of you with the antenna pointed AT you. I 3D print tails for all mine with an extended antenna holder that is away from the carbon. No issues, even at distance. I even changed to ELRS thinking that Crossfire was inferior, but while it may not get the 40-50km distance of ELRS, it's still great with correct antenna placement. If I was flying freestyle in a 5" at 1 km, I'd consider that far enough outside of a 7", and long range should have a diversity receiver in it anyway so you can have an antenna in front and rear. Make sure your Tx antenna is either horizontal or vertical to align with the antenna on your quad (or whatever it does a majority of the time.)
The smaller the antenna, the better the carbon blocks it. Perfect solution is diversity with one horizontal/one vertical, but small quads and wallets cannot support that, especially for a large collection of quads so...........
Oh, and remember that anytime the end of your antenna points directly at you, that is a 'null' point, meaning 'no signal'
All a balancing act between range, weight, ease of use, and crash protection. Have to see what makes sense for your kind of flying.
@@MangorilleYes I hear you. Sorry if I was preaching to the choir. Beer and enthusiasm.
@@minkorrh No problem, thanks for the comment. Happy flying!
I use this (and the pyrodrone one) on my 5 inch drones, and have no issues. It suits my needs just fine. From my perspective, I think you are making a mountain out of a mole hill. Go fly ELRS on 2.4, and enjoy it.
How far away do you typically fly and at what transmitter power? This can work well in the right application.
That's my faaaaaavorite way to mount the Immortal T in the Glide (dead center in between the base and x plates) for durability but my god does it hurt the signal strength :)
Glad to see I wasn't the only one that came up with that approach!
Super relevant topic, as iFlight is shipping AOS5 BNFs with a minimortal (not sure if same in your vid, but looks the same size). This is a ridiculous antenna to put on a 5" kwad IMO. Now I need to buy a full sized one and find a way to attach it to my drone.. Should've payed more attention when buying, really upset.
Really? I tried checking their website but they don't have any pictures of the antenna with the crossfire receiver option. Antennas of this size are usually for 2.4ghz systems like ELRS.
@@MangorilleYeah they just attached it to the arm with one single zip tie too. I'm gonna be avoiding their stuff from now on!
Had many problems on various quads with the minimortal, too many failsafe's have happened for me to ever bother again.
Agree, really only if you're flying super close to yourself. I can see the use for an indoor tiny whoop.
How are you getting signal strength in your goggles? Been out of the hobby awhile and recently reinvested into digital.
All depends on what air unit and goggles you have. If you have the DJI Vista/Goggles V1 or V2 you can follow the instructions here: czcams.com/video/A3MtAsy77zk/video.html
If you have the O3 air unit, you can follow the instructions here: czcams.com/video/KIis4hB_duQ/video.html
The 03 with the v2 goggles. So no special things I have to do in my transmitter? Just remember hoops to jump through in the analog days.
@@creationlabsinc.189 Not anymore, with the later versions of Betaflight the telemetry is automatically sent to the flight controller. You don't need to setup a telemetry channel, etc.
@@creationlabsinc.189 Just make sure you have the correct DJI radio for the system that you are going for.
1:49 DJI O3 Air unit can work with TBS crossfire or ELRS 2.4GHz? Also DJI O3 Air unit can work with Radiomaster Boxer?
The DJI air unit will only work directly with a DJI FPV Controller 2. However, you can add a receiver for any of those protocols you mentioned and then run those. The Radiomaster Boxer (assuming you get the ELRS) version will work with the O3 when you add an ELRS receiver. For example this one:

Nice video. How could you display Crossfire LQ in Goggles 2? I have both the Evoque V2 O3 and Flywoo Explorer O3 with crossfire but I could not display the LQ at the Goggles 2. BT 4.3.1, any advice?
Thanks. Check out this video: How to get your custom BetaFlight OSD working on the DJI O3 Air Unit | MSP Canvas Mode is HERE!
czcams.com/video/KIis4hB_duQ/video.html
@@Mangorille thanks for the answer, I bought them as BNF and supposed they had the MSP enabled cause I see warning messages at my goggles 2, only the LQ from Crossfire I can't see. Do I have to do something at the receiver? For the Goggles V2 I was sending the LQ through channel 12 at the RX and enabling RSSI at the Controller tab in betafligh, putting it at 8, so I could see the RSSI at goggles.. A hack from Joshua Bardwell
@@KostasGur Silly question, are you sure those elements are on in the OSD tab? You don't need to send the telemetry through a channel anymore, put all that back to default. In the later versions of Betaflight, all the telemetry is automatically sent from the receiver to the flight controller.
@@Mangorille :-) yes at least the LQ is on, well I am expecting new pair of goggles 2 from DJI these days and cannot test is cause at the old ones, the left lens suddenly blurred, they said coating problem and sending new glasses, so I have only the Goggles V2. Do this work for the V2? If yes, I will try disabling the LQ at the RX and see what happens. The Iflight evoque v2 came with betaflight 4.3.1
@@Mangorille finally I put everything default in RX and receiver tab and now it works with goggles v2!
I want to get into fpv and can't decide which goggles should I take v2 or g2... If you have to take only one and use only with o3 which one would you chose? I am afraid about blurriness and comfort.
That is a really tough one and will depend mostly on how well the Goggles 2 fit your face and how important price is to you. I've got a video on this: czcams.com/video/sikWCDD_JL4/video.html
I own a pair of V2 goggles. I love them, they work with 03, OG-AirUnit(even though support is dropping) and work with CaddxVista's-Light. The video quality is great. I have never used the G2, but because the V2 are so good, I have no desire to pay for G2. I am currently waiting on the HD-0 goggles, so I can start experimenting with analog and support the open-source mindset of Carl, and HD-0. You may not be interested in that, but I feel like it will give you an idea of where I'm at. Going forward with DJI, if I was all in and planned on only ever using DJI, I *might* consider the G2. But personally, I feel like waiting for DJI's next gen. (G2.1, if you will) would be best. This is my personal opinion, from my experience in fpv.
I have both. I had to add the after market foam to the G2 Goggles to make them fit right and not pinch my nose. I would get the V2 if you are just starting out. You will sacrifice some quality with O3 units but not enough to make a huge difference!
@@JDDupuy Hey, which foam did you use and do the goggles still rock back and forth side-to-side (kind of like they are pivoting on your nose)? The V2 is a really good deal right now with the price cut but there are still software bugs to be worked out when using the O3 mode (e.g. loss of bindings when you switch modes) and I suspect they will be discontinued at some point.
I sell my v2 and buy G2 and now a am very happy! 😜 G2 is the future!
ELRS for the all around win. Going half a wavelength on the tbs antenna really cuts down the range. Hard to justify crossfire over ELRS these days.
Agreed, especially as more reputable manufacturers start making elrs hardware and news of elrs going 100km! Crossfire should still have a frequency advantage for those wanting as much range and penetration as possible though.
With that all said to be fair any of these are simply not optimized for 900MHz. ELRS, Ghost, or Tracer will all have performance advantages when using effectively 2.4GHz optimized antennas.
@@heroflying Yup, I got better performance on ELRS with the ceramic antenna at a much lower power output.
I mean I can go several miles away, as well as maintain deep penetration in wooded areas and concrete buildings with zero failsafe with crossfire. I couldn't possibly justify switching, because it has never once held me back in any way.
@@andyhoughtaling6319 Crossfire has been great, the challenge is the antenna size for smaller quads.
If your quad was made of solid gold and you were flying over the ocean would you use crossfire or Elrs? I would personally use crossfire.
Good use case for crossfire, what if you were flying a 3" quad where every gram matters 100 ft away from yourself?
I bet the devs of elrs are more talented and I'd bet there's more of them. I fail safed crossfire 4 times within 300 meters of myself, and in my starter pack one rx was dead on arrival, no help from support in either case. I'd put floaty foam on the quad or an empty water bottle and I'd do elrs.
Not good idea to use 1/8 wavelength antenna IMO. Personally hate bulky immortal T design which is essentially made of bicycle cable. My tip is to use TBS lighter and cheaper thin wire 1/4 wave antenna. Make it tough by feeding it through some tough but light yellow inner nyrod tubing or similar.
I've seen the video by MrSteel where he shows how he uses zip ties and shrink tubing to make that antenna work but it always looked unpolished to me and was hoping that this tiny antenna would work for my kind of use case (close range freestyle).
it works on my micros but to be fair i have to push 1watt lol.
Lol 1watt, thanks for sharing.
Wow that performance was terrible. I'm done with crossfire, elrs is simply superior.
Crossfire is really good if you have the space for the antenna and receiver and need massive range. For day to day, ELRS works really well. I haven't used crossfire since I changed my Tango 2 to have the internal ELRS module.
