Can someone advise me the Sbus equivalents in terms of performance and physical size of JR 8411 and 8711?

Thanks

Pardon my ignorance as I know nothing about S-bus. At present I fly with a fair range of different servo makes which are mainly digital, but some are analog. If I was to go totally Futaba and S-bus, would I have to replace all my existing servos with S-bus compatible servos?

There is a programmer available that alow you to use standard servos with s bus. I am using s bus programming with JR servos in my GS P-51

U can either replace them or by a decoder for the regular servos

I did some googling:

Not only can you use existing conventional servos operated via a number of SBD-1 S.Bus Decoders, but you can also convert any make of Rx to S.Bus, not only Futaba, by installing a SBE-1 S.Bus PWM Adapter.

I guess most of you on this thread already knew that, but it gives me, a long term JR and Spekky user, food for thought.
