F-Port

Nexus supports F.Port on: The 'TX' pin of Port A, B or C or by remapping the SBUS to a TX for F.Port.
F.PORT

F.Port is an Unverted protocol over a single wire so must configured with both of these options enabled.
Remap SBUS to F.PORT

Motorised Tail

To use the NEXUS with a motorised tail the Servo 4 needs to be remapped to Motor 2. This can be done in the CLI using the following command (just copy and past this into the CLI then push [ENTER]).
