after starting SITL with:
sim_vehicle.py -v ArduCopter -f gazebo-iris --console
and starting Gazebo with ardupilot_gazebo plugin:
gazebo --verbose ardupilot_gazebo/worlds/iris_arducopter_runway.world
i changed the parameter SIM_WIND_SPD to 15 but the behavior of the drone shows no difference in gazebo. Furthermore the parameter wind in the console is showing -/-, but the parameter is saved with 15 to the eeprom.bin.
I assume that i won’t notice any difference in guided mode anyway, but even in stabilize the drone is drifting slowly across the map with rc 3 1500 (and it seems to me that the direction is random, but i’m not sure).
I use Gazebo 9 and the latest ArduCopter V4.0.4-dev
