I have a Goldberg Ultimate I have decided needs some color changes BAD in order to be able to see it well. I am going to put a yellow pattern on the top wing. My question - for looks or for making it even easier to see do I need or should I put the same pattern on the top of the bottom wing? Is it visible when flying. Or have any of you done it just because it looks better on the ground? I really don't want to go the work if not necessary.
