At our circle the wind is the deciding factor. The most people we have had is 4 to fly. It is also easy to see who is up next the way the planes are lined up. Usually the planes are lined up at the take off point side of the circle. The lines and handle are lined up parallel to each other outside of the circle going away from the vehicles that are on the unmowed grass outside of the circle. Chairs and boxes are close to the airplanes. Need to see it to understand what I am trying to say. Have fun, DOC Holliday
