DJI Digital FPV Air Unit Disassembly & TrueRC Singularity 5.8 Direct Solder | DC5 Titan Antenna Fix!
ฝัง
- เผยแพร่เมื่อ 18 ก.ย. 2020
- Let's disassemble the DJI Digital FPV System Air Unit, remove the MMCX connectors, and directly solder the TrueRC Singularity antenna to the board!
This project, dubbed Franken DC5, was fraught with fails! The iFlight DC5 Titan frame, in our experience, has poor antenna placement, which impacts the signal quality and crashability. We attempt to resolve this by replacing the convoluted antenna setup with a directly soldered TrueRC Singularity and a RotorRiot HD1 antenna mount.

really well soldered. this is a superb upgrade over the ever-so-wonky MMCX issues with the vtx. thanks
Thanks bud, good option for folks who have already broken the MMCX. The good thing is that the whole board is the ground as well in case you damage the traces on the side.
I build this frame with caddx vista and I used the stock antenna tpu mount just I used the top hole, much much better than factory design its so beautiful with caddx vista single antenna
Thanks for sharing your setup. Ya that would work well. I wanted to keep the air unit at the time of making this video. I have since changed all the kwads over to the vista.
:-) 5 minutes wiser, I'll remember that one. Good content!!
Thanks bud, glad you found it useful!
I'd take a well executed soldered antenna over those pesky mmcx connections every time. Nice job.
Thanks bud, definitely agree! :)
good work, i have a dc 3 and a dc 5. bolth are costum builds. the dc3 is build with tyro 79 elektroniks and motors, and the dc 5 is a mamba stack 722s bluetooth and ummagawd v2 2306 motors 2150kv. but i put a vista with polar cam in it. just orderd the caddx air unit, for the dc 5 for better recordings. with bf 4.2 and rpm filter and stock pids, it runs like a beast. dont need to go full throtel, most of the time eaven in dives i use 50-75% throtel. and i smasched it a few times good into trees and ground, and i still have a complett spare frame. never brock a arm ore anything on it. 4 me its a flying tank. what would you say are the stock antennas as good as the true rc. im using the v2 goggles with stock antennas as well.
Thanks! I enjoyed the DC5, was a good frame minus the weird antenna layout.
Thanks a lot!
No problem, happy flying!
It worked perfectly! I soldered just 1 to the board and everything was back to normal. Though I can see some issue down the road with the exposed gap for the air unit, maybe seal it with glue?
Either way, you just saved me a lot of money! I ordered some mmcx so i can eventually fix it properly.
Ahh thank you sir.
Awesome, glad to hear it worked out for you. Rotor Riot used to sell the compatible MMCX connectors, have a picture on our Instagram of them installed if you want to see how they look.
@@Mangorille no worries I ordered them off some random parts website, and unless theres a unique spec specific to that model.. I mean it looks identical to the air unit one.. please tell me there arent hidden polarities or something rather lol
@@purpleAiPEy That's great, usually would be something physical like the size of the pin or length, etc...
Hi there. Thanks for the video. I did something dumb.... powered my dji air unit up for a firmware update but forgot to attach antennas. Do you know if i likely damaged the air unit? It was powered on for about 5 minutes...
Thank u so much sir you saved the day for me lol
No problem. Did your connector break in a crash?
@@Mangorille yep ! Lol
By default Dji Air Unit is waterproof but in your case its not any more. By the way, you may shift Dji Air Unit to the back. In that case you do not need long cable any more.
The air unit is not waterproof or even dust proof. In order to be waterproof it needs seals and covers on all openings, which it does not have (think of the bind button, the SD card slot, the space around the antenna connector, etc...).
Yea I was gonna say how in the hell you figure it’s water proof it’s got a giant holes on every side of it. I think you could have gotten your extra length from those antennas if you would have just de soldered the connectors instead of cutting them with the exact o knife excellent video !
@@FLMan180 I fully agree with you and l also think like you are, but depend on my experience I may tell that my version of Dji Air Unit is waterproof :) please check this video: th-cam.com/video/DfpHdl6G97M/w-d-xo.html I changed some parts after but not Dji Air Unit.
I like the sound effects 🤠
Thank you!
this improve the quality of the signal?
Probably minimally, based on whatever is the loss of the connector. This is more for people that break the connector.
Hi, does cutting the cable length of antenna affects the antenna power?
I haven't found any noticeable change in the signal.
@@Mangorille cool thanks..
Drill holes and add stand-offs farther forward and notch upper plate
That would work too
Hello had a question on how you removend the brass connector on the board before hardwiring the antennas. Did you use a solder Iron to heat it up or a heat gun.
Hey. I used a soldering iron with a large tip and a bit of solder already applied on the tip. The old connector came off really easily that way.
@@Mangorille Hey thanks for the quick reply and the "tip". I'll try that and see if I can take it off and hard wire like in your video.
@@88_shadesoffpv No problem. Let me know if you have any other questions. Are you going to hardwire the stock antenna?
@@Mangorille Yes. Planning to built a waterproof craft 5". Having seen some videos from others, I want to attempt to build one. Will probably have to order longer antennas, don't really know yet. I want to change their possitioning instead out coming out the back, I'm going to try side mounting like I've seen on some of these videos. Now that I can hardwire in the antennas, I going to attempt to surround the openings of the air unit with high temp silcone and seal it.
@@88_shadesoffpv Sounds good. It has a lot of openings to seal. :)
hi goood video i do the same but i put the original dji antena but i don't have the same range i am lost the signal 50% in 500 meters do know why ?thanks
Hey, thanks! I had this done with the original antenna as well with no negative impact to the range. Do you have any pictures of your solder points? Perhaps the solder did not make good contact or when the antenna was cut, there was a short between the inner and outer sheath. You do have to be very careful when cutting the antenna.
@@Mangorille maybe I was have the low mw I change today and try tomorrow and if I have problem again I open and I send you photo sent me the email
@@fpvcanada7434 Sounds good. Mangorille at gmail
Hello friend, I finished all this process that you showed, I reassembled everything and connected to the drone, and I do not get the image in the dji goggles, image transmission stopped, try to bind again and it does not work, could you help me please
Hey, when you did the soldering, are you sure that there is no short circuit? Check under a magnifying glass.
What about try moving air unit to back of qwad
That would work too. Wanted to retain one of the selling features of the DC5 Titan which is the central mounted stack and air unit.
Well done man! I hate mmcx )
Thanks bud, ya, they're too delicate especially when most frames need you to bend the antenna cables at sharp angles.
@@Mangorille Man, I've replaced today MMCX on my unit using your tutorial. And it works!!!! Thanx a lot. Now my range is perfect again!
PREVIOUS VERSION OF DC5 WAS MUCH MORE SUCCESSFUL IN MY OPINION
sry 4 caps
Ya, it's definitely a more conventional design. No worries about the caps. :)
This is why I ordered the dc5 HD frame this was poor design. And the air unit, flight stack is too tight for nice wiring job
I liked the mass centralization but agree that it causes a lot of other challenges. Having to use the SMA extension, being limited in stack height, etc... I do like the fact that you can take the whole top plate off and have the air unit, camera, and antenna come out together in one piece.
get rid of that music !!
Wth I like the music
@@FLMan180 well you enjoy..bye
