I ALWAYS put a strip of Monokote fluorescent orange on the leading edge of the wings on all of my planes.I rushed an ARF plane into the air because I wanted to fly it that weekend and did not put my usual leading edge color on it. I literally dissappeared on landing. I put the orange on the wing that afternoon. Find a color you can see and put a 2" stripe on the leading edge. Any fluorescent Monokote color shows up well.
