Which 'Sensors' included in sbus telemetry data?

ArduCopter Copter 4.4
1

Is there a way to change what ‘sensor’ data comes from FC to the Rx?
It would be good to have ASI and RPM but they are not included it would seem.

Thanks

This is the list that Ardupilot sends to telemetry.
It seems Inav has a longer list.
Are there plans to add a few more things? Would be good to get RPM and airspeed on the list.
