Yes I guess there is an S-Bus and an S-bus.2 type of communication. Telemetry sensors need the S-Bus.2 type of communication. And the newer Futaba Servos are also S-Bus.2 communications. The 3 channel decoder I know also works on the S-Bus.2

There is some VERY confusing language in the R7008SB manual that makes it look like channel 8 is for S-Bus servo usage and you have to configure the Rx mode for that and that the S-Bus.2 port is only for Telemetry. That is not the case as I see it..

I think the manual was written early on when the Futaba Servos would not communicate with the new protocol (S-Bus vs S-Bus.2) Most of the Newer Futaba S-Bus servos mention they use the S-Bus.2 protocol.

In ALL of the installations I've done I have never set up channel 8 as an S-Bus port and I have hubbed all of the decoders and telemetry devices to the S-Bus.2 port. A year and a half later and 200+ flights with NO radio problems. (knock on some wood)

Happy Flying!,
