So, yes it's the Inverted S.port pad you need to connect up to your TX3, and SBUS out to your SBUS pad as you've done.

So if you've reflashed your R9MM with the Flex firmware, have you done the same flash on your module and rebound the rx?  You shouldn't have to mess around with any cli commands for this.   In the ports tab, set whatever UART your SBUS is on to serial RX and on UART3, set telemetry output to smartport.  Then in the configuration tab, set receiver type of serial and the serial receiver type to sbus.

This is equivalent of having -
  serialrx_provider=SBUS
  serialrx_inverted=OFF
  serial_halfduplex=ON

Ok guys, I've just swapped the connection to Inverted Sport, so now the only connections are GND, Voltage in, SBUS OUT to my SBUS pad on my FC and Inverted S.port to my TX3 UART.

I have also reflashed the R9MM with the FLEX firmware (not the F.PORT one) but still have had no luck, also tried messing around with these commands:

set serialrx_provider = FPORT
set serialrx_halfduplex = ON
set serialrx_inverted = OFF

But no luck and no stick input in BF

It is a bit confusing as FrSky's view of what inverted/uninverted is is different to everyone else.  So your 5v/GND/SBUS_OUT are correct, but odds on you'll want to use the inverted S.port connection into your other UART.  I haven't checked the Mamba f405, but most F4 cards have a single inverted UART for putting you SBUS signal thought, and everything else is uninverted.  FrsSky's "inverted" s.port is actually uninverted, so it should work.

Here's a video I made on this very subject




Thanks for your reply currykitten, I watched that video you sent but I was still confused on whether I should use Inverted s.port or s.port/f.port.
So shall I also connect the inverted s port to my other UART (TX6) whislt leaving my S.PORT/FPORT still conncetd to a UART(TX3) or shall just connect Inverted S port to UART(TX3) and not use the S.PORT/FPORT on the R9MM?

Hi guys,

I'm getting a bit confused on setting the FRSKY R9M system. I'm using a R9MM receiver and I'm trying to get it connected through SBUS and smart port and not through FPORT since is wayy to confusing.

I have used the 'SBUS_OUT' and the 'S.PORT/FPORT' pads on the R9MM, But I'm not too sure if I'm supposed to be using SBUS_OUT or Inverted S.port?

Quad is the Diatone R349
FC is the mamba F405

I tried a few, all with very disappointing results until I tried the FeiYu Tech mini 3D which is fantastic, but unfortunately not produced anymore so unless you can get a second hand one :shrug:

I'm looking to a build another My Twin Dream and was wondering what would be a good gimbal to use to mount a gopro 4?

Very nice - it'll be a lot better with the prop brake on :)

Is there a way to put vario on the OSD?

 Hi Steve,
                 Cheers m8, it still needs some tweaking and it would be nicer in the fast climb using 4S. This would mean a 12v regulator to feed my VTX though.
   FrSky do a dedicated micro receiver with built in Barometer, and Vario, so you can listen to that as well if you want, or just watch the altimeter in the OSD. The GPS is all mounted inside the Fuz to keep it aero, its surprising how fast this model is, even on the glide..
  At least Im using my cheap 868mhz system, it does work now though....
 Pleased it can cope alongside 1280mhz video...

                                                                                                :vulture:

Then why the "flat earther" comment? The fact is the regulations won't affect the majority of modellers whether they're in a club or not because there simply aren't enough police to go around.

What will happen is though an unlucky few will be pinned to a wall and flogged, based on misleading arguments, flawed regulation and an absolute lack of respect for the umpteen years of safe operation they've previously demonstrated.

It's pretty sick to be honest - changes mean nothing, the system doesn't need to exist in the first place and it's only coming into place because of the above reasons. It's nothing to do with safety, and everything to do with someone, somewhere making bank.

You ridiculing people is a bit below the belt considering you are, and have historically been one of the people who the new regulations are apparently designed to fight against in the name of safety. I'd bet good money that when you flew you operated safely albeit illegally. That's because the law is flawed.

Laws with flaws get ignored - that's exactly what this regulation and registration system is going to be up against. Merely entertaining its existence means you accept it.

I personally do not like having my rights taken away from me, especially when it's for no good, demonstrable reason.

I agree that the back in the day when FPV was a new and exciting adventure there where many times when the envelope of legality was pushed by many. Either in ignorance or stupidity. But for me that is in the past. Its become far to fresh in the public's mind, but the biggest threat would be from club members dobbing another member in. My 1 hour uncomfortable brush with the law 2 years ago put me wise to that, so no, I wont fly outside LOS again.  So I agree that it will go underground and by and large will stay within LOS where a club is involved. 

I attended the registration testing, as did several others from my clubs, to gain first hand knowledge of the system and try to input some common sense.  Looking at the changes made I think we did make a difference. However, as its now on the statute books it will happen.  Its up to the individual to examine their conscious and decide if they are going to comply or not. Its always been that way, whether its paying the old Poll Tax, registering to vote, having no car insurance or a valid EA rod license.  Sorry Steve I dont see it as picking sides and for the record I think the registration system is flawed and wrong and I am much more concerned by the EASA legislation due in 2020.
