Hey, Glad you like the plane, adding a little to the nose I think is what makes it hover better, wait til you fly it in the gym. I just built a few more and it does hover better. The balance is pretty close where you got it, I would try it around 6-7 mm back. But if it maintains altitude rolling with not to much throttle then it's pretty close . I fly mine about 6.5 mm back. Can't wait to see it in the air I'm sure your right about the color scheme. Thanks Bill
