Greetings group,
My tx is JR 12X DSM2 but I am really keen to try CGY-750 and have had CGY-750 on my desk waiting for Orange 9ch DSM2 RX with S.Bus for more than a month now.
Now that Orange comes out with a 6ch DSM2 RX with S.Bus output, I wonder with this 6ch rx will I be able to use full functionality of 750? Especially the flight mode adjusted flip/roll rate?
My understanding is they each look at the end-points of a channel for the percentage of full rate. But that a lot of Futaba flyer are using 3ch FASST rx with S.Bus so I am a bit lost here.
I can also go get that conventional RX to S.Bus device adapter but will have to deal with whole bundle of channel signal cables and at $50 a piece, it is a bit of a rip-off.
Please kindly advice.

Regards,
Ramins

Normally the Sbus contains all the channels that the transmitter has – at least that’s the way that Futaba receivers work. I would expect that with a 12-channel transmitter that you will get all 12 out of the Sbus port.

For full functionality with governor you need 10 channels. You can lock the gains if you don’t have enough channels to control them from the transmitter.

Thanks Ben,
This confirms my guess on how FASST system works, TX encodes all channel signals into one datagram while RX decodes them all and throws them all into S.Bus but only provide designed conventional channels.
Don't think DSM2 works in the same way but have just received dispatching notice so 750 shall get airborne in couple of weeks time. Hooray!
