I've located Cybro with this method, as he shows up on the map clear as day when you are flying near his airfield. Just shoot the bush that correlates with the map and you get a kill. I think the only easy way they will be able to fix this will be to remove all radar reports under 65ft, as they already have a variable set for being below radar. Right now it seems that it displays everyone in icon range, even if you aren't physically able to see the icon of the plane because of other variables like being low to the ground decreasing icon range.
