I have been flashing several Revolution (regular, not mini) with Ardupilot firmware and running without much problem. Now I want to connect a Jumper R8 receiver to Revolution which has been flashed with Ardupilot firmware. The RC output from the R8 is S Bus. The manual of Revo says the Main Port can accept S Bus, among other protocols.

1) Do I have to re-map the Main port to accept S Bus ?
2) How can I do the re-mapping when Revo is now running Ardupilot fw , not the original firmware ?

Thank you for yr help.

The hardware (Revo) can do it on MainPort.  I have several set up (LibrePilot firmware) that exact way.  I greatly suspect that the Ardupilot firmware can do it, but you would need to ask this in an Ardupilot forum.
