## SIH on Flight Controller Hardware {#sih-on-flight-controller-hardware}
SIH can also run on flight controller hardware with `SYS_HITL=2`, replacing real sensors with simulated data while running on the actual autopilot.
See [SIH on Flight Controller Hardware](hardware.md) for setup instructions.
SIH can also run on flight controller hardware by replacing real sensors with simulated data while running on the actual autopilot. Setting it is a simple as selecting the appropriate SIH airframe. The easiest method to run the SIH Quadrotor X is to set the parameter `SYS_AUTOSTART=1100` then reboot the vehicle.
::: tip
To ensure that the vehicles behaves well, it is recommended to reset all the parameters to firmware's default before modifying `SYS_AUTOSTART`.
:::
The following airframes are supported
| SIH Airframe | SYS_AUTOSTART | Status |
| --------------- | ------------- | ----------------- |
| Quadrotor X | 1100 | Stable |
| Airplane | 1101 | Experimental |
| Tailsitter Duo | 1102 | Experimental |
| Standard VTOL | 1103 | Experimental |
| Ackermann Rover | 1104 | Experimental |
| Hexacopter X | 1105 | Experimental |
See [SIH on Flight Controller Hardware](hardware.md) for more details and compilation instructions.
