We have 7-9 guys that fly choppers and not one fly the pattern that even a 40 size plank does. They fly back and forth in front of them selves, going maybe 75' out from where the took off from. Maybe some chopper pilots fly the pattern, but not at our field, or the other field I fly at. We all get along, but do so by not flying while these idiot chopper pilots are flying, as they do not, nor will not use the established flying pattern.
