I would echo what NorfolkSouthern says, and just figure out a way to add some contrasting color to the wings and tail to make it easier to see. I just use the "Dark on the bottom, Light on the top" kind of color pattern. It works for me. Heavy stripe on the bottom would seem to work also. The 4 star is an excellent flying plane. The only thing I would lose is the expensive 30% fuel and go to 10 or 15. I use that in all my 4 strokes, Saitos and Magnums, and all my 2 strokes. I have the 100 in my Top Flite P-47, and it flies beautifully. Your 4 star should have unlimited vertical.
