Hey there, i am using the tumsimulator for ros indigo. I can simulate a drone and with standartmsgs i can fly around. Now i wanna use a flightplan. I found, that you can pub a node to autoflight/start to a realdrone. someone made it for simulated drone? i tried:

rostopic pub --once ardrone/start std_msgs/String "data"

"data" also must be on real drone. i tried to load it from the roscd.
