+5. (Optional) Configure your manual controller priority and failsafe:
 
-   - [COM_RC_IN_MODE](../advanced_config/parameter_reference.md#COM_RC_IN_MODE) to "Joystick/No RC Checks". 这允许操纵杆输入并禁用 RC 输入检查。
-   - [NAV_RCL_ACT](../advanced_config/parameter_reference.md#NAV_RCL_ACT) to "Disabled". 这可确保在没有无线遥控的情况下运行 HITL 时 RC 失控保护不会介入。
+   - [Enable a mode in `COM_RC_IN_MODE` that enables and prioritises the controllers you want to use](../config/manual_control.md#px4-configuration).
+     The default `RC or MAVLink keep first` should work if you plan to only have a Joystick (no RC).
+   - You can set [NAV_RCL_ACT](../advanced_config/parameter_reference.md#NAV_RCL_ACT) to disable manual control loss failsafe while flying in a simulation.
