    How do I calculate the area covered by 4 radio transmitters with a range of 10 km each in a 10 km square?

    I have 4 radio transmitters, each in a different corner of a square with 10 km long sides. Each radio has a range of 10 km. I need to calculate the area where you are in range of all four transmitters. Unfortunately i have no idea how to do this. Can anyone help me? //Swither

    About how much thrust will be needed from the engines to levitate the hovercraft? Also, wouldn't it be possible to put on another engine for moving it forward and then use a rudder controlled by some kind of RC servo to steer it? Or would the hovercraft get to heavy then?
