I didn't, but that's probably why it was ok... everything was triple checked.

So here are the list of issues:

First motor direction: Each and every one of the motors spin the opposite way that I expect them to. 2 & 3 go CW, and 1&4 go CCW. - Solved... figured it out... I used BLHeli configurator to reverse the motors... after that I checked and everything is good and each motor spun up just fine. 

Receiver: Still working on this one... something is wrong when trying to get it to recognize SBUS in BF. I think I have some ideas on possible root causes but I'll need to take the top plate back off and try looking at everything. It's getting a little late for that tonight.

VTx: when powered up the VTX is getting rather warm and all I see are grey bars... I must have something hooked up wrong and I might try one of my other antennas.  I'll try to see if I can figure out what it is tomorrow when I take the top plate off to check out the receiver.

I am sure you will figure things out. If you haven't already

But just in case, for SBUS, double check on the ports tab that the correct UART has serial_rx selected. Then on the configuration tab under receiver select serial based receiver for rx mode, then select sbus for serial provider.

As for the vtx, it is normal for them to heat up. Especially when we aren't flying and keeping the air moving around it. Some people I have seen use tiny heatsinks on them even. Just don't power it on without an antenna. As for the grey lines, when I first started I thought my VTx was bad but soon realized I had forgot to switch everything to NTSC or PAL. Also, scanning doesn't always find the right channel. My Eachine Goggles 2 are notorious for this, so I always manually select channels and bands when I need to change them.

Just some of the first things to check, should you find everything is soldered and connected properly.

Good luck Vegas! 

It can be tricky to get the FrSky receivers working on the Omnibus F4 and its clones. F4 based boards, unlike the F3 boards need a dedicated inverter to understand the inverted s.bus signal. There's only one fitted on these boards and you need a specific version of Betaflight for it to work.

I need to replace the Spektrum receiver on my Armadillo with an XM+ and I have a genuine V1 Omnibus F4 installed in that. I'll have a go at doing that this weekend. Hopefully, my experience should be applicable to your build as well.

In the configurator, do you see a UART 6 available?

Thanks guys, good points. Some of which I've been experimenting with so I might be on the right path.

I started to figure this out last night based on the various help text in BFC but it still wasn't working. The reason was after reading on here so much about UART1 being for USB I was trying to use UART 3 or 6... I tried with MSP on and off, telemetry on and off, all kinds of stuff... This morning I looked up the issue online and it said to use UART1... In my head I said "BS, that's going to make it so that I cant have the Rx hooked up when connected to USB... and who knows if I can connect again... then I look in BFC... and wouldn't you know... there's a special port set up just for USB how smart and user friendly! This is actually a case where reading and learning on this forum held me back (first time I can think of really). I put UART1 for serial RX and TADA! working... now just have to remap channels and I am going. Going to look that up after I post... darn throttle is mapped to roll right now and while I know that I do a lot of rolls when I am flying I think I'd rather have a stick that centers to do that :p

I bet you this is it... The thing is I butchered my cable in order to get an OSD wire that it turns out I didn't need thanks to the way this FC works ... I was planning to use the connector without the OSD wire to put the cable back together but I'll have to look up to see if the menus will work without it because otherwise it'll be worthless... I hadn't considered that part unfortunately...

I may have a look at the cable that came with the CCD camera on the vortex... if the pins are right I might just be able to use it... (crossing my fingers on that one)

I haven't flashed the FC or ESCs because the FC is 3.1.0 and the ESCs are 16.5 (which seems to only be 2 half versions behind). I may flash the FC though because 3.1.7 looks like it's worth the upgrade. Luckily the version wasn't my issue! (very happy for that)

Have you tried UART1 for the Taranis? It would be awesome if I could have actually figured something out that would help you get the omnibus going.

Here is how my port setup looks this morning:

Yep (see screenshot above)... it was the second port that I tried to get the thing to work and it still didn't like it. I found the solution thanks to MaTT GRaNT on rcgroups

Here is the post that pushed me to the solution:

Quote:All figured out now. Apparently on the Omnibus boards, the sbus pin and uart 1 are shared. I had to move my bridged uart 1 rx and tx to uart 3 (SDA/RX 3 and SCL RX 3). Then I set uart 1 to Serial RX on (MSP off) and uart 3 to S.port in BFC and presto! All fixed! 8hz/8hz and OSD management in BFC is a wonderful thing!!!

In theory if I can get video working I could possibly get in the air this morning!...... we shall see.

Just as a side note, i would recommend staying on 3.1.6 for now, as i see some issue reports for 3.1.7 that even some of the main dev's can't seem to figure out. https://github.com/betaflight/betaflight/issues/2852

Good to know, thanks!

I'll probably get in the air with 3.1.0. It's the version I am running on the Vortex so I know that it works fine for me. I'll get the latest and greatest later :p

Alrighty... so I got the new VTx which worked right without any issues. I've put everything together and while I hate where I am mounting the VTx everything else is in shape.

Going to try to get it in the air at a nearby park tomorrow morning... crossing my fingers that everything is set up right

I updated the OP but here is the photo of it being done... The room was rather dark so I had to bump up the brightness which shows off the fact that I took the picture on a rarely used dusty desk... don't judge me :p I'll get out the swiffer later

Looking good, hope all goes well! Think you can expect a tad more punch than you're used to from the vortex...?

Really like the name & color scheme.

Yeah this one is significantly lighter but with as much or more power so I'm expecting some punch!

No Swiffer required, just arm the bumblebee haha. Nice build

That looks great Carl! The phrase "Float like a butterfly - sting like a bee!" comes to mind

Dude the color scheme and the style of that FPV cam and mount really reminds me of some mad max style Equipment. It looks well made, but it also looks kinda thrown together somehow. Don't ask me why xD

Post a video man, i wanna see it flying!

So took it out to the ballpark this morning and got set up... everything armed well and I did a little bit of wiggling it around to get a feel for taking off with an under slung battery and it popped up in the air just fine... biggest problem I had was that I was flying right at the sun was coming up making it difficult to see, plus I think I am getting noise from the ESCs so I'll need to address that, and my camera angle is different on this one so what looked like my typical 20 degrees or so ended up being maybe 10... So lots of floating in one place...

The one thing that was really obvious about it was how much less the flight controller had to fight the weight. I do a flip then stop the flip and instead of it whining as it struggles to balance out it sorta zipped and was done with it... very happy about that. I also have more response when trying to change the velocity of acrobatic moves so shifting from slow to fast to slow again is more immediate.

I need to turn P up on roll and pitch and maybe give it some more I to balance it out but otherwise it flies great!

I'll upload the maiden flight video tonight... there isn't much to it as I was really working to get the feel for the quad but I still wanna share anyway... kinda like when your baby takes first steps... sure it's not anything actually spectacular but you wanna show off the video to everyone anyway.

That's great to hear!

Congratulations on your first successful build.
