-    // @Description: This is an RC input channel for requesting engine start. Engine will try to start when channel is at or above 1700. Engine will stop when channel is at or below 1300. Between 1301 and 1699 the engine will not change state unless a MAVLink command or mission item commands a state change, or the vehicle is disamed.
