I was wondering about having them in my vision, I fly a Champ with an aera sitting on the glaresheild and I don't even see it unless I'm looking at it. Sitting in the cockpit of the -8, I'm comfortable that they will not bother me. Especially if I paint them.
Manual says DO NOT PAINT, but was told by a respected authority that a thin coat of flat black would not be a problem. Makes sense considering some put them under the cowl.
I could not completely get the 3" recommended distance from windscreen, but did get the recommended minimum spacing between them.
As you can see it's not flying yet, but I don't expect any problems. We shall see.
