Great job, congratulations! You went about it the right way, that's appreciated. Antennas are a science, it is enough if one part is just 1 mm longer than it should be during soldering , and the antenna is already out of tune. It seems that you succeeded, the truth would only be known during the measurement, but that requires expensive equipment. The antenna can be detuned even by the presence of the original antenna, which is inactive at the time when you are flying the ELRS, acting as a capacitive load. Anyway, it worked...
Thanks! Agree, I usually wouldn't mess around with antennas but no other option available. I tried to keep the active element as close to the original size as possible.
Well done! I've been using the Zorro as my main transmitter, but still prefer the tango's form factor. Putting it in internally like this is perfect!
Thanks, I love the Tango 2 form factor and the versatility of the ELRS receivers so this made sense.
I just discovered your modifications ! I'm going to do it gives me all i want ! You did a great job with both video !
Let me know if you have any questions. Been working great for me so far.
Hi, I received everything and I wonder how did you open/cut/disassemble the Elrs antenna from the module to do the modifications ? I'll like to do exactly like look. It looks like the right way to do it.
@@132blondiHave you checked these two videos?
ruclips.net/video/FoPtx2x_a0k/видео.html
ruclips.net/video/RodegZjiQGk/видео.html
@@Mangorille yes, I did. I'm looking for the technique you use to get the antenna in the same state than minutes 2:40. Did you use just a knife? Or heat ?
@@132blondi Just a xacto knife to slowly cut away the plastic and heat shrink. Take your time but it is fairly easy. Separating the Tango 2 plastic antenna is what takes a good half hour.
Very nice, I've been there a year ago but didn't manage to open up the stock t2 antenna. So I was just using an internal happymodel rx antenna instead
Thanks! I tried using an internal bardpole antenna originally but the reduction in range was noticeable.
Haha, I really didn't have to wait long for this video! Awesome work - that's something I can aspire to one day! My Tango 2 is currently sitting beside me with an Immortal T crudely shoved through the wire channel and hanging out the back - not for a module, I'm just trying to get crossfire working again further than 20 meters... I've already swapped out the PCB (v3 replaced with v3, old and new SD cards tried), Nano Rx, Rx Antenna, upgraded and downgraded firmwares on everything. The TX antenna was my last hope, I really thought that must be it. It's made for a really long week and I think I'm about 1 beer away from just buying a new Tango 2 and being done with this living hell! And at least that way I could use the old one as a dedicated SIM controller. Anyway, I think it's time for a beer.... Cheers!
If you've already swapped out the motherboard and antenna, are you sure the problem isn't with the receiver in the quad?
@@MangorilleI thought that, but I swapped the RX out too and somehow it's still no better! The replacement RX had been tested working fine on a different quad, so I was sure that RX was ok and that the TX must be ok. But it made no difference and now I'm thinking I was going crazy and that it must be something wrong with the TX! I had already ordered a new RX on Friday but it's not been posted yet due to Easter holidays. I did a telemtry bench power test today but think I did it wrong and looked at downlink (TRSS) instead of uplink (1RSS / 2RSS). Got no change in reading which made me suspicious of the antenna but in retrospect I realise I was looking at the wrong data, so I'll try again tomorrow. The Immortal T Antenna attached on to the u.fl much more positively than the factory antenna so maybe theres still hope that is the issue. Might try direct soldering it tomorrow after another bench test and before I give up completely.
@@CoopzVideo You're right a beer is needed indeed. You've replaced most of the parts that could be the culprit. Did you try in a different location? Could perhaps be a lot of interference where you're trying to fly.
@@Mangorille Good thinking, but I've been flying from the same bench I normally do - a literal benchmark haha. The indoors bench test today showed promising results looking at 1RSS so I took it outside and the range was a lot better. So it seems like my problem was caused by both the ipex on the PCB and the u.fl on the stock antenna. I know I can solder the broken antenna to my old board or buy a new antenna for the new board, but in the meantime I have removed the factory antenna and just stuck the Immortal T inside the top housing, under where it says "TBS TANGO II" on the front, to try out a slimline version. The range seems decent, and I did end up ordering a new Tango 2 last night (I'll never be stuck in this situation again!!) so I'll try and get some numbers to compare the two and let you know what difference the internal antenna makes. I don't know if the Immortal T is too small for 1W TX but i figure it's probably rare it goes to 1W anyway. Maybe your next mod will be a slimline sleeper...!
@@CoopzVideo That's good news, you'd probably lose video long before the TX goes to 1W. I've gotten crazy range through a bunch of houses on 500mw with crossfire.
awesome
Thanks Bot!
Good stuff!
Thanks!
Nice mod
Thanks! I’m posting an updated guide next week using a 500mw module instead. :)
Thank you so much for sharing. Could you show exactly where did you cut on the stock happymodel antenna, I'm not quite sure if I can afford to mess it up since it only comes with the TX module. And for the reassembly of the 2 aircraft wires to the crossfire antenna, did you cut off the stock ground and active element of the crossfire receiver completely before soldering both the 2 aircraft wire on to it?
Start by using a Xacto knife to slice the black plastic at the T of the antenna. Make sure you don't go too deep and damage the wires inside. I sliced off the top, then the bottom, and finally the sides to expose what you saw in the video at 2:50. Then go ahead and cut the main wire about 5mm from the top. At that point you can pull the active element out and you end up with what you saw at 3:39. For reassembly you cut off the black ground element from the crossfire antenna and stick it into the longer side of the ELRS antenna. Go ahead and solder it up so that it stays. Then you cut the active element from the crossfire antenna trying to match up the size as close as possible to what came off the origina ELRSl antenna. Once you do that, solder the active element to the smaller side of the original ELRS antenna.
@@Mangorille Thank you very much for the very detailed guide, really appreciate it! Hope all goes well :)
@@chesterlim15 No problem, good luck!
@mangorille
Quick question about the antenna... well, 2, actually...
Is the bigger antenna really needed for 25 to 250mw?
Also i hfoubd myself with an extra crosfire antenna, the one on the tango 2 remote thats has tue big aircrat wire. Can i just cut it down to 2.4ghz size? I just dobt kniw what the little pcb is for... ant ideas?!
Thanks. Amazing videos.. i just got all the materials to start the modd sometime this week!!
Welcome. If you don’t need the best range you can use the receiver antenna but it will reduce the range. I’m not sure what the PCB does, but I suspect it’s to help tune the antenna to the right frequency.
@Mangorille yes you are right. I found out that the pcb tunes the frequency from the factory. It looks like I could take one of the resistors out and bridge the other, and it would work as if the pcb is not there. At this point in time I'll just roll with the rx ant.
Thanks for the reply!!
Hello. I am not understand, you take ufl crossfire antenna 2,4 tracer and put inside tango 2 ? What is it antenna on 3:01 tbs tracer 2.4 ?
I took a UFL crossfire 900mhz antenna and just used the connector from it to connect to the ELRS antenna that came with the Happymodel module. The ELRS antenna that it comes with has a SMA connector so we're really just trying to get rid of the SMA connector and give us a thinner more flexible wire.
@@Mangorille what exactly is the antenna, what is it called, you have on the video at 3:01
but in your video, you take some kind of antenna and soldered to it the ears of the antenna that came with the hepi model @@Mangorille

interesting mate

Hey man love these vids. I have a slim module from the jumper tlite, would that work? if so would I still need to get the power adapter thing or not?
Hey buddy. Thanks! I couldn't find any information on that module. If you want to send me the measurements of the board and some pics I can tell you my best guess. I've done this mod with the Happymodel Slim and the BetaFPV Nano.

BetaFPV: ruclips.net/video/RodegZjiQGk/видео.html
@@Mangorille I think it's smaller than the iron man thing I'd just wondering if it's pinned out the same
The pin out where it would connect up to the radio if you were using an external rf module should be the same otherwise you wouldn’t be able to swap modules between different brand radios. You can always use a multimeter to verify.
@@Mangorille did you get the link?
No. You may need to email it to me.
is 4.0v the highest it charges too? because i have never seen mine at the full 4.2v. also notice yours is also at 4.0v.
I've seen it get to 4.1. If I recall, there's a voltage calibration you can do if yours is reading too low. You'll need a multimeter to compare the actual battery voltage to what is being displayed.
I wish TBS would swallow their pride and make a ELRS version of the Tango 2 or maybe Radio Master would just copy the darn form factor like they did with the Mambo/Boxer lol
Ya, they did allow us to add an external module so that's something at least.
Hello Mangorille, do you recommend the dji fpv controller v2 for longrange currently with the update improvements?
Hey. I wouldn't recommend the controller 2 for any kind of long range, I lost confidence in it fairly quickly especially when it fail safed right in front of me (mind you on the old firmware). Never had that kind of problem with the old black DJI remote after years of flying so I lost confidence in it. If you fly long range, you'd want something like crossfire.
Why not crsf? I mean range is sick, all od that hasle with elrs for smaller rx?
For me the biggest benefit is the smaller antenna and lighter receivers. If you fly whoops, you have more options with ELRS too.
