Hi All Re David L's note, my experience is just the opposite. I fly free flight, and seeing the models from a distance is important, as you can't time it if you can't see it. Generally dark colours on the bottom to stand out against sky, and bright colours on the top and 'sides' to stand out on the ground. Silver Mylar ( reflective ) is the best method of 'spotting' models at a distance as it flashes at least once every circle. Top of tips and fuselage sides work best Also I fly Scale gliders, and definitely white is not a high vis colour. Models with big block rego on the bottom stand out much better. To make fluros work, they need to be of a fair area, and outlined in thick black, and are better for looking down on, not up. The atmosphere and relationship between the sun and viewer has more effect than all of the above ! There was a Kooka at Bordertown white with red tips (nearly half span) with big bold GNZ on the bottom, and it could be seen for miles...... maybe that's the answer Cheers Col

Some years ago I found one of my comp F3B models hard to see at a distance in its all white paint scheme. I put large flurescent geen/orange and red stripes on the wing-and it made no difference. Even gliders with red noses and rudders are no more visible at a distance. I remember reading somewhere once that small distant objects appear gray/black regardless of coulouring. The reason now eludes. Solar cells are fine on an engine cover, as the doors are not carrying any structual load. I wonder about solar cells placed on wing roots however!
