S-Bus Virgin needs a helping hand - Futaba R6303SB S-Bus Receiver

[RcRotaryMadness]

Hoping someone can confirm my understanding...

What it is, I have a Vbar & a standard R617FS RX - which means I have to use patch cables to connect the two together I am also using the vbar's governor which means all the sockets are taken on the vbar making power supply tricky and it also (annoyingly) means I can't use bank switching in the vbar .

I was considering making a power bus to neaten the problem - but of course it doesn't fix it all..

SO I've been looking into S-Bus...

According to Futaba the S-Bus R6303SB RX is compatible with my TX (Futaba 7C 2.4ghz)
It is also able to work on upto 8.4v (although advertised specs seem to vary between retailers) - I am running a 2S HV Setup so would need to be able to run on HV.

Looking at the dimensions it seems more like a Micro Reciever in physical size so I'm wondering if this is a FULL Range RX?

I have googled and I think it is - its the R6303SB"E" being for park fliers and small helis?


Just hoping someone can confirm that this R6303SB RX:
1) Will work with my 7C TX
2) Is a full range RX
3) Will not burn out when I plug a 2S LiPo in?


If so - If you have one for sale please pm me

Cheers

Yes it's full range, 2s will be fine. Mini or full size Vbar? If mini can Y a servo port pop another power in there or as I do split power from rudder servo feed power in there and servo power to rx. If full size all your patch cables carry power so your more than covered.

Check out my thread there is a simple sketch of power routes using mini/YGE/2s and Vbar gov.

I got one last week to go with my new 8FG - used a LiFe battery on it and its full range so no probs.

Its very small and neat installation on my 600n, took me a while to be confident it would be ok but after research seems the cheapest S-Bus Rx you can get that will fit bigger helis.

Not sure if it works with your TX but the Futaba site has a guide :-)

Thanks Maj, nice link & setup there, now I know that its a full range & 2S I'll get one and set it up with that - the S-Bus should make things a lot better all round really! Certainly less wires & less connections which must be a good thing.... Just have to make sure that "1" S-Bus connection is a solid one.

Thanks for confirming my thoughts - Like you I was a little unconfident in it as the dimesnions are are on the small side so straight away questioned its range & voltage ability.

The other thing is I have never looked into S-Bus before so all the RX's are totally unfamiliar to me... the only RX I've ever needed is my trusty R617FS... Standard full range rx.

Yeah as you say its the only option for me really... Its the cheapest full range HV S-Bus RX that is also compatible with my TX... Theres a more expensive one R6303SB IIRC that will only work with the 8FG and so on... mines an older TX.



Anyway I'll pop a wanted ad for one and if no luck I'll just order a new one.

Thanks for your help - its helped clarify things!

Good thread this!

Hopefully someone can answer my SBus/VBar Q. (Sorry for the hijack!)

I run my gear on 6V and use a BEC Pro. I'm running a full-size VBar and was wondering what's the best way to power it all? On my Goblin I've wired the two power wires that the BEC Pro has in to 2 spare ports on the VBar. This is providing power to the Rx too which is connected via the Aux port.

Is this a suitable method? Is it ok to power the Rx through the one lead coming from the Aux channel? Or should I use a Y lead in the 3/B port on the Rx with the BEC pro power in one and the ESC signal in the other? The 6203SB has another 2 channel ports but no idea what they do and they don't give power to the Rx either.

Hope I'm making sense!

If your looking for the correct info for Futaba Rx's and their Tx compatibility then I always use this source:

And a complete list of manuals for Futaba equipment can be found here:

Sounds like a good solution, the rx draws next to no power so one route in will cover up to 4 amps so perfectly fine. It's the Vbar side where you want at least 2 power routes in as its the servo's taking the most current.

6203 has 1 s-bus and 3ch ports. Each port is connected to the rx power bus so all can take power. The 3ch ports can take servos so basically you could select which function you want in the transmitter to those and then drive from those ports. Only time I did this was select ch1 throttle and put my throttle in there rather than Vbar. This was before gov days.

On my fusion there is two power leads from the helijive one goes to the Vortex and the other to the R6203. So the RX port is the other connection to the power supply...

As has been said, the rx neads little current, the servos need most.
Plug boths leads from your esc/bec into the vbar. The rx will be fed from the positive on the signal wire. If your worried add another pos/neg only lead from vbar to rx

[Guest]

Full size it's pretty straight forwards, on a mini needs a little more thought. If using a Jive or built in bec its also very simple, throttle from esc supplies power, slave plug in full size vbar or Rx if mini and sbus will carry power as well. Just non bec, mini vbar need to be creative.

Thanks for the feedback gents

On my 600 my ESC is plugged in to the 6203 instead of the throttle channel of the VBar. Is this correct? It seems to be working after 200+ flights on it, but could never get to the bottom of whether this is actually correct or not. With BeastX the ESC always had a place in the FBL controller, not the Rx. I will be using the CC gov BTW.

[Guest]

There's no right or wrong there but if your not using the Vbar gov its beneficial to do what you have done as it saves processing time. The Vbar actually has more latency but due to the look ahead features makes for a very good governor. If you think about it the transmitter puts out the signal, the receiver picks it up then passes it to the Vbar which processes it then passes it on. With the throttle in the rx you skip a load of that so you can see external gov go rx route if poss but JR/Speccy use sats so use Vbar th port.

That makes perfect sense

Thank you

Thanks for the responses everyone, dani_r's question has helped me with my setup too.. Will be much more simplified and tidy when the rx is switched over for an s bus!

[RcRotaryMadness]

ok a bit of a follow on question if you can help... my 6303SB rx arrived today and i notice it has a "normal" and "high speed mode" ... is it benneficial to use high speed mode with the vbar via sbus? does the vbar work on highspeed mode?
