I have the Complete DJI system and I'm using the JB FC F4 but I can't get v-bat from the bird to show up in the goggles any suggestions .. And yes the wiring is correct I assuming it a problem with the FC .. what FC do you all recommend using that works with DJI.

I'm using Betaflight 10.6.0 and the newest CL racing F4 1.4.1 firmware for the JB FC . I'm get N/A where the vbat should be in the goggles display .. I also have DJI fast s-bus protocol enabled.
I'm glad that we were able to get the FC working via our chat on Messenger. Sorry we had a miscommunication earlier. When you said, "it's working now," I concluded the problem was fixed. I didn't use my FC for this build because the NBD FC is specifically designed to be plug-and-play with the DJI Air Unit.

Bump for this video in 2021 - at around the 8 minute mark setting the SBUS rate to FAST saved me from buying a new Air Unit, I didn't know what to search for before but if your DJI Tx is not 'talking' to BetaFlight, double check that Tx is set to FAST (using goggles) and Rx is set to FAST using BetaFlight CLI shown at about 8 minutes in this video. Thank you Joshua!
Hi Joshua I want to buy exactly everything in the entire play list, Frames, ESCs, FC, batteries, soldering iron box of screws flux stick, soldering wire et al; the lot exactly as shown and repeat your build. I am having trouble locating the build list associated with this play list. Lyle
Hello I wanted to ask something, I have the airunit cam mounted on a carbon support when I do the continuity test with the multimeter if I put the negative in the xt60 and with the positive I touch the screws of the frame and the frame therefore sounds in theory ce continuity, should I isolate the cam? or does it not give problems?
Would this same build work with the older ocusync air system as well? Unfortunately the new air unit you’re using isn’t compatible with the DJI goggles RE I have so I’m stuck to the older ocusync system.
@@JoshuaBardwell thank you, in the beta flight CLI when I type set "sbus_baud_fast = on" It say ##ERROR## invalid name. I've activated the ports in the video and I am using a Mamba f405 mk2 FC. I have also downloaded all the drivers for windows from your other video about betaflight and BLheli. could this be caused by a bad solder connection?
I am also stuck on the CLI get sbus step. My Betaflight configurator is 10.6.0, Firmware BTFL 4.1.0 and Target is EXF722DUAL . There seems to be no sbus options under the get command. I saw another video that indicated the DJI protocol would be in the pull down menus for 4.1, but that does not seem to be the case. The iFlight controller came preconfigure, maybe I need to flash it again to make sure it really has the latest 4.1 ?
can the dji air unit be linked to other contrller or with just the dji controller ,,,the problem im having is that there is no bind button on the reciever its all wired to the air unit ,,,,,so im thinking that i do need the dji controller,,,,,, it has the crossfire installed
The Air Unit can only bind to the DJI controller. But you can use a Crossfire receiver and the DJI Air Unit on the same quad. Here's a video showing the binding process: ruclips.net/video/8SYiMctDex8/видео.html

I have a iFlight SucceX-D Mini F7 TwinG Stack (F7+40A ESC) with a BEC 5v 2.5a included. Is this enough to run a 6s battery or would I need an extra regulator to power my dji air unit?
On an F4-based flight controller, UARTs cannot be inverted through the CLI. There must be a hardware inverter installed on the board, which is why there is a dedicated SBUS pad on the FC (that's the pad with the hardware inverter). On an F7-based flight controller, all UARTS support inversion and you can connect SBUS to any UART you prefer, although the manufacturer may have placed the pads with the intent of a certain UART being used for receiver. If you need to put SBUS to a different UART (like because you lifted the SBUS pad) then the workaround is to do the "uninvert hack" on the receiver. This gets un-inverted SBUS from the receiver and you can connect it to any UART RX pad you want. If you do the "uninvert hack" then you must go to the CLI and type: set serialrx_inverted=on save
Hi, nice videos! Waiting for the next one! One thing you do not mention (at least I didn't notice it) is what goggles are necessary? Are the DJI Digital HD FPV Goggles required?
gotta love these prep-working vids.. josh is on vacation, best thing, he's probably leaning back while releasing these;) if he didn'T say anything, people would probably never know he was gone..:)
You can use any receiver and transmitter that you normally would use with a Betaflight FC: Spektrum, Frsky, Crossfire, Etc. If you use the DJI controller then you must use SBUS as shown here.
The air unit takes between 2s and 4s voltage, so you'll have to get a voltage regulator to step down your 6s voltage to somewhere between 2 and 4s. At that point, you should be able to use whatever battery you want. I built mine using the Hobbywing G3 stack which has a built-in 12v pad.
The ESC that JB uses here is 6S-capable and will give 9V to to air unit regardless of the battery you use. You'd want lower KV motors, ideally around 2150KV if you want a good balance of performance between 4s and 6s.
Hi Joshua, I'd like to use the Kakute F7 FC for my DJI build (not the HDV as I already have the original F7). I will only be using 3s and 4s Batteries. My understanding from the manual (it's rumored that you helped to create it), is the I will need to use the GND and B+ pads to power the air unit to get the correct voltage. Also, looks like the yellow DJI HDL (S-Bus) wire will go to R6. The UART RX (OSD) and UART TX (OSD) wires will need to go to an open UART on the board (RX to TX and TX to RX). My question here is can I use the same UART, or do I need separate ones? Also, are my assumptions above correct for the power and SBUS connections? Thanks in advance.
Really great video. Your explanations of each step were greatly appreciated. I'm still trying to wrap my head around using the DJI Air Unit fully and if I can use it with my Qx7 transmitter? Many thanks!
@@JoshuaBardwell going to run an XM+ receiver. I think I'll disconnect yellow and brown wires from air unit, but then I'll still need to connect 5v, sbus, and ground to FC for the XM+, right?
Hy Josh! When i wanna build the same config like yours and i wanna use my taranis i have to solder on my receiver to rx and tx pads on the FC, is it necessary to cut the yellow cable from air unit to FC?
Hi Joshua, you said in this video that your jb f4 fc with 9v voltage regulator is not good enough to power up the air unit. But your fc manual states that it can deal 9v * max 1.2A equals 10.8W. the specs on the dji website of the air unit states that input power varies between 7.4-17.6V and 4-9W. Wouldn't your JB f4 fc voltage regulator suffice after all to power up both the air unit and camera? Love your videos. Keep up good work!
Thank you so much ! My Geprc Rocket Plus dropped 100" upside down onto the asphalt and dented the air unit (doa), broke all props, and destroyed the prop guards. I had accidentally bumped it from acro to angle mode and it always drops to the ground. Wrote dji to ask if that normally happens. They did not say and had my send them an export file for them to analys. Waiting to hear back. Well, I bought a new air unit and installed it. It would bind, but no controlling to the FC. Did the get abus_baud_fast = ON and it works now !!! :-)
Hi Josh, thanks for your informative build tutorial. I have sort of related/unrelated query about the DJI system. I realize it's a 'proprietary/close end system but am wondering if it were possible to hack the transmitter (probably would be illegal to say the least) and send the signal to a third-party receiver/monitor....completely by-passing the goggles? I know the goggles have a usb-c but as far as I understand, it's not a A/V output. I'm hoping DJI will allow something like this in the future firmware updates but for the moment I don't think it's possible. Someone mentioned you can rent a box for viewing the live feed but know any details on that. The reason I'm asking this question is because I'd like to mount the 'air unit/camera' on an older Inspire 1 to be used as a high quality HD FPV viewing source. thanks.
@@JoshuaBardwell thanks josh...pretty much what I would assume. I'll have to wait until perhaps they provide further functionality with a firmware update. Btw...are there any other HD camera/trans/recev option that you're aware of that come anywhere close to the DJI image quality?
I am 100% not in charge of how long it takes RUclips to generate subtitles. There is no way for me to influence that. And there's no way I'm going to sit and write subtitles for the whole video by hand. So unfortunately, there isn't anything to do.
I am going to guess you are on an earlier version of Betaflight where that option didn't exist, or where it had a different name. The high-speed SBUS option is only in 4.1.
Hi nice video !!! Like it !!! Thanks for the information ! juste a little question, does the Kakute F7 HDV - Holybro with the regulator 5v and 8v 1.5a is enough ? Or i need to buy a Pololu Regulator ? that write on the description of the FC "Filtered voltage output for clean, noise-free video. 2 On-board regulators output 5V and 8V. 5V output up to 1.5A to power peripherals such as receiver, FPV camera, or LED strip. 8V output up to 2A to DJI FPV VTx."

Iflight protek35 question with DJI air unit.. Everything works but NO receiver signals Connected everything. ( Original air unit to FC cable. 2 connectors.)

I Really want to see some sub-250 gram 3-inch DJI builds, with props out of view. My theory is that the majority of folks influenced by the intro of DJI HD FPV are the same folks who want props out of view, and also to remain as legal as possible while flying. Call me crazy, but see how many people agree.
The iflight DC3 is about the only one I've seen, my build will be done tomorrow. It's 160g without battery and 1404 xing motors. Plenty of battery options keep it under 250. Plus it's a deadcat with no props in view. If it turns out to be too fragile of a frame I'll swap back to the acrobrat.
I've been planning on building the DC3 also, but haven't been able to find all the parts available and affordable from one source in the States.. I'll probably have to resort to Banggood or iFlight and just wait. So how do you like it? Fly it yet?
@@RobRidesCarolina Yea I finished it yesterday and she flies great. It's very quiet, smooth and more powerful than I was expecting honestly. So far I love it.
Good to know. Where did you get your parts? I'm adding up prices, and availability, and if I have to order from China to get everything from one source, the BNF is really just as cheap as building.. and might even get it faster. I just wanted to get some spare parts as well but hmm.
There is NO set sbus_baud etc =((( I am at newest betaflight version I got this: ruclips.net/video/y-wK7NESx8Y/видео.html UPD: I found the solution!

But I steel can not see DJI NDL in the menu and in the goggles this option is grey now and unavailable to change. Thank you Joshua!
That option only exists in Betaflight 4.1, which is currently in Release Candidate. If you installed the latest official release, it's 4.0, and it doesn't have that option.

@@RobRidesCarolina Yea I finished it yesterday and she flies great. It's very quiet, smooth and more powerful than I was expecting honestly. So far I love it.
Good to know. Where did you get your parts? I'm adding up prices, and availability, and if I have to order from China to get everything from one source, the BNF is really just as cheap as building.. and might even get it faster. I just wanted to get some spare parts as well but hmm.
@@RobRidesCarolina I got the motors from getfpv and the frame and stack from race day quads.
Got the wires backwards 🤤
There is NO set sbus_baud etc =((( I am at newest betaflight version
I got this: ruclips.net/video/y-wK7NESx8Y/видео.html
UPD: I found the solution! I just needed to check "show unstable versions" and re-flash firmware release 4.1.0 and now my receiver WORKS!!!
But I steel can not see DJI NDL in the menu and in the goggles this option is grey now and unavailable to change.
Thank you Joshua!
That option only exists in Betaflight 4.1, which is currently in Release Candidate. If you installed the latest official release, it's 4.0, and it doesn't have that option.
@@JoshuaBardwell hi Joshua, maybe do u know now I can not use dshot1200 it isn't listed, but my FC is Mamba F722s (does support 1200), how to fix that? Thank you.
UPD: I found
Update (Sep 2019): DShot1200 is officially removed from Betaflight 4.1 as it no longer supports 32K looptime and the developers believe it brings no benefit under 8K looptime compared to DShot600.

Not interested in DJI at all.
Why not?
First
Is Joshua now sponsored by DJI like Rotor Riot?
