   Note, this is the successor of [Gazebo Classic](../sim_gazebo_classic/index.md) (below).
 - [Gazebo Classic](../sim_gazebo_classic/index.md) is less accurate and less heavy-weight and supports many features and vehicles that aren't available for FlightGear.
   It can simulate many more vehicles at a time than FlightGear and it allows for different types of vehicles to be simulated at the same time.

+- [JMAVSim](../sim_jmavsim/index.md) is a very light-weight simulator that supports only quadcopters.
   많은 쿼드콥터의 근사치를 시뮬레이션하는 경우에 권장됩니다.
+- [SIH](../sim_sih/index.md) is the lightest-weight option with zero external dependencies.
+  Since SIH is headless and runs physics internally, it can launch many instances with minimal resource usage.
+  It supports all 6 vehicle types (quad, hex, plane, tailsitter, standard VTOL, rover).
