@AlbertKimTV 3 года назад

It is rated for 6S but I recommend using a 9V/2A BEC to power it instead. I hear 6S usage over a long time will shorten the life of the Vista from the extra heat produced on 6S over a lower voltage.

@scolty 4 года назад

Great video. Why is the RX cable soldered to the TX pad and vice versa?

@AlbertKimTV 4 года назад

That is how the UART connections work. RX to TX and TX to RX. That's just how it is.

@scolty 4 года назад

Thanks very much 🙂

@zachmachina 4 года назад

@@scolty rx is receive and TX is transmit. Think about baseball. You throw from your hand (transmit) and catch in a glove (receive). You wouldn't throw a ball from a glove or catch one with your hand. I mean, yes we've all tried both of those things, but you get what I mean. Your hand throws a ball and a glove catches it. TX sends signal and RX receives it.

@AlbertKimTV 4 года назад

Don't have that board but it should have come with a manual with wiring diagram. Just match up the wires to the same pads on that FC like in this video and it should work.

@Eliaschr1992 4 года назад

@@AlbertKimTV allright thanks for the response. The thing about this FC is that it doesn't have any solder pans only contacts. And what I can read from the manual is " FC integrated 3.3V, 5V, 12V for a receiver, VTX, camera, buzzer, LED and other peripheral devices" does this mean it will it will be ok to hook it up there even if I fly with a 6s battery? Do you know if the FC will be ok to support 12 with 2a ? Or should I get a regulator between camera and the battery?

@dawsonmobley 3 года назад

In the video you point out a specific pad for the signal ground (brown wire). My understanding is that every ground pad on the fc should be the same electrically? Is there something unusual about that brown signal ground wire or can it just be connected to any ground pad on the fc? Thanks for the clear and concise how-to's...you are one of just a few youtubers I go too for information like this.

@AlbertKimTV 3 года назад

All the grounds should be the same on most flight controllers. There are some where it may not be and you'll have to consult the documentation for those specific cases. Those are rare however.

For the RC control, only SBUS will work. There might be a way to make a UART RX pad to work as SBUS but that will vary by FC model. You'd have to look at the FC manual for that information.

@stevefpv4669 2 года назад

Thanks for this vid, at least confirmed what I read on the wiring diagram of HGLRC F722. I'm confused, went over it several times. I couldn't use the wire harness that came with the FC because it's too short (tough luck - would have been easier to just plug in both sides) so I used the cable that came with the air unit which is long enough and solder the cables to corresponding FC pads. I haven't used the last 2 wires because I am not using dji controller. I'm sure I have the wiring correctly done and I verified continuity between each cable of the plug that goes into dji air unit to each pad on the fc. I have MSP activated on the right UART number, I have OSD enabled in BF, dunno what Display does but I cannot enable it for some unknown reason. I have Custom OSD enabled on the Goggles but still not getting any OSD elements. Is there anything else I can still check?

@AlbertKimTV 2 года назад

I'd have to take a look at a photo of your wiring and parts. Post a photo to Instagram and tag me @marblekit.

@stevefpv4669 2 года назад

@@AlbertKimTV Finally found the nasty cause of my problem, did felt like the plug that goes into the air unit was a little bit harder to insert than I was used to, in fact a tiny little piece of sh**** cable silicone tubing (hard to even see, probably from when I was removing it from the ends on the other side of the cable to solder to fc) got stuck in the air unit female plug part blocking connection to either white or gray or both, geez that one got me struggling. I even checked continuity of cables but didn't see that one coming. Either way still many thanks man for taking the time and wanting to help me in the first place, much appreciated. Will not forget that, maybe I can help you with sth one day.

@Flyingwoodchuck51 2 месяца назад

Do I really need to use the flight controller or can I just direct power to lead and then to goggles?

You need the flight controller to send the arm signal so the air unit will go to full power. Otherwise it stays in low power mode.

@FPV_Reject 3 года назад

Just got my first air unit. I also thought your wiring was reversed. But yeah it's correct. The problem was that the FC labels were on the bottom of the pad. With the other FCs I've worked on over the years (analog), the labels were typically on top of the pads. Thus causing the confusion I guess. Thanks for the tutorial video!

ik this might look like the dumbest question ever but in fpv what type of wires should you be looking for? for repairs and stuff
