Knowing what connects where is a nightmare. :(

Looks like you're doing a fine job there, all looks like it's wired up correctly so far :)

Couple of things though....

1) Do those ESC's not have a BEC and is that why you are using one? Only asking as I thought all the afro ESC's had a BEC?

2) If that's one of the FT952 or TS5823 vtx's, you may want to use an LC filter on the power line. I've had 4 of them now. 1 was DOA, 2 Popped the minute I plugged them in and the last one is still going, but had terrible interference from my ESC's when I powered up until I installed the LC filter. Might just have been my ESC's.

3) Oh, and if the MinimOSD has had the 5v mod done already, don't accidentally put 12.6v through it. Don't ask how I know that.
 
The UBEC I'm using was recommended to me on the build instead of the afro ESCs, so I don't have an answer for that except I just followed advice from the seller. :)

Interesting point on the vtx, I'll look into it.

The 12v cable on the MinimOSD is in the BAT2 slot which I was told should show me the battery read out via the OSD, rest of the MinimOSD is 5v though so I'm not sure if it has a mod done already or not! :)

I've got to figure out how to configure the MinimOSD yet with that software!

Ok, looking at those ESC's, looks like they have a BEC built in (think I can see it written on the label?) so you shouldn't need the separate ubec. The ESC's provide about 500ma at 5v so will power the Naze and the receiver fine.

I'm also not sure how the Naze will react to having 4x ESC BEC's and a UBEC plugged in.

I'm also not sure why whoever sold you the kit recommended the UBEC. There was a problem with some afro ESC's a while back where they put the wrong voltage regulator on them so they were outputting 6v which meant a few people fried their Naze boards. Only affected the Acro version of the Naze though as it can only handle 5v ish. The full version (the one you have with baro & mag) can handle 16v nowadays, but not recommended. That's how I fried my OSD as the naze just passes whatever voltage it gets to the other 5v pins on the board. I was lucky not to kill my rx as well.

Generally recognized config is to have just 1 ESC connected fully to the naze and the other three, just the signal wire (yellow). IDK, it will probably be ok and I haven't heard any stories about people frying their FC through not doing this.

As for the OSD.....

If you can be bothered with the whole 90 mins, this is a great video...

Sounds like the OSD has been prepped for 5v only, but it's fine to connect the battery positive to the pin you mentioned. You can do it through the Naze too, but not sure if there's any benefit doing it that way. Mine is an older version that doesn't have those pinouts, so I have to do it through the Naze.
 
Shabby photos, but ready for FPV- maiden tomoz now.







Major hold with the RX. Spent too much time trying to get my X8R to work using SBUS in cleanflight only to find out I needed a bloody inverter.

Not the tidiest job and a few will need tweaking once I've established if it flies properly.

Have done the obligatory bedroom hover and all seems ok. It didn't try to take my face off, so all good!
 
Oh, one final spam post. Foxtech now sell the arms for 6" props so I've ordered 2 sets. Eventual plan is now 6045 props and 4s.
 
looks like a great machine to fly.

My sunnysky's arrived. Just heard there are issues with Afro 12 ESCs with them though. Apparently fixed in the latest firmware so I've got a USB tool ready.

I only have the signal wires plugged in, not got round to taking the other wires out yet from the picture. :)

Ah OK. How about this instead then?

It trades the antennas for a 250mW vtx, but is only from China. However even with ~£35 VAT added on top its about the same as the other kit is available for in the UK.

For a few quid more, I'd probably get this

Pretty much the best Vtx you can buy at the mo, and supposedly puts out more than the quoted 600mw at any of the frequencies below 5.8Ghz. It would future proof you to a degree......

The other one should be fine though. I only have a cheap mini 200mw on my quad and it does fine now it's got a filter....

It flies. And flies well. And quickly.

Well, it did.

Y'all know the Naze disarms with the stick at bottom left right? Yeah, maybe don't try a low throttle, descending yaw stop at about 30'. Especially not when the hex hovers at about 30%.

Pancake landing under zero power = detached top plate.

2.2Ah battery is quite a bit heavier than the 1.5Ah ones and I used the wrong screws to attach the standoffs.

Ho Hum. Nothing seriously broken.

Will put it back together tonight, add the other bits and pieces, fly again saturday.

In this minimal spec, with 5040 props and just pootling about, I got about 9 minutes before the lipo alarm went off!
