 RC input is configured on the port marked RCIN/UART.  
 This connector supports all RC unidirectional RC protocols. Two cables are available for this port.  
 To use software binding of Spektrum satellite receivers you need to use the Spektrum satellite cable.
-To used bi-dectional protocols such as CRSF/ELRS, a full UART must be used instead. UART8 is pre-configure for these RC inputs. See [RC systems](https://ardupilot.org/copter/docs/common-rc-systems.html) for more details.
