FIXED!! I missed the wiring from the R-XSR....I assumed yellow was SBUS (NOT!) and I was sending the Smart Port signal not the SBUS. I just noticed I had the SPORT and SBUS reversed. It's working now and I am a dumbass....now I can finish setup. Sorry for all the drama. JW

I can't remember where I came across "on the newer Omnibus F4 Pro boards UART1 is assigned to the GPS and UART6 is assigned to the RX" in my lengthy search but that's also the way it (on a PNP quad) originally came from the 'factory", when it wouldn't connect corectly I did a complete restore to...

I did solder those two pads together, still 1500 on all channels on the receiver page. Odd that's the only thing not working and it's the same when powered by USB or battery. Starting to wonder if the FC is a dud. That would be my luck. JW

EDIT: I just found a YouTube video about soldering/jumping the SBUS pad to the ground and did that, still straight 1500 all channels on the receiver page....

Good Morning All! For some reason my new FC and RX aren't playing together nicely. I'm running iNav 2.2.1 and everything seems to be working except the receiver page shows all channels @ 1500. The newer version of this FC is supposed to have an internal SBUS inverter and I've tried both the...

Thanks for the tip. It arrived and I just checked...….it came with iNav 2.2.1 installed! No flashing FW needed. Connected right away, didn't even need to download any drivers (but I do have a new laptop?). Now to get a receiver installed and wade into the setup.....Sweet!

I mainly want the GPS for RTH if I loose orientation. I have two helis with the Spirit/GeoLink FBL system and I don't use rescue but I do occasionally use RTH if I'm at all disoriented. It's very cool, comes back just like an obedient hunting dog. Position/Altitude Hold is also nice if I need...

Hmmm....looking closer at that link it appears the Omnibus F4 v3 is discontinued, the F4 Pro v3 looks to be supported? It calls out Omnibus F4 Pro- "Sometimes called Omnibus F4 v2 Pro, but also exists v3, v4 & v5 versions". Wonder if I would I risk "bricking" the FC by trying the iNav FW...

Thanks wafflejock. Hmm...it sounds like it might be just a bit above my programming/setup skill level to get iNav on it. I'm sure BF will be fine for now. If not and I really want to try iNav I'll swap the FC out for an iNav supported one later. Anyway I'm finding out electronics/parts for...

I own several helis and have my first PNP quad on the way. It comes with Betaflight installed on an Omnibus F4 Pro V3 flight controller. It also has a Beitian BN-880 GPS that I would eventually like to utilize (RTH/PH). After scouring the internet I would prefer to use iNav instead of...

I've ordered an Arris Explorer 280 PNP and a FrSky R-XSR receiver (Friday/Saturday delivery?) and will use an X9E radio I fly my helis with. "Murphy" tells me the FPV/quad will be a totally different animal but I'm ready for a new experience. I'm sure there will be somewhat of a learning curve...

I've been building/flying/crashing helis for several years and always wanted a quad so I finally ordered one. I actually wanted a quad way back when I started but somehow ended up coming home from the LHS with a heli. Anyhow I'm pumped about my new machine including wrenching on it "if I...
