If you go on a plane with it, make sure to set it into client mute mode. That way you are not connecting people on the ground from hundreds of miles away that won't be able to see each other once your flight leaves the area.

My general rule of thumb is that if your node is less than 20 feet above the ground, you should be using client mute. If it is between 20 and 100 feet above the ground, you should be using client. And if it is 100 or more feet above the ground, you can likely use router mode.
