i guess i'm in the minority, but i find using transparents on both top and bottom makes visibility very difficult. the problem is that when the sun shines thru the plane one of the colors completely filters out the other so determining orientation is challenging. i also found my plane harder to see period when using transparents exclusively. granted if you know exactly what you're doing at all times it's not as much of an issue, but half the fun of flying is trying new things and why make it harder on yourself? i've post a few pictures towards the latter part of this link : http://www.rcuniverse.com/forum/Star..._262560/tm.htm that will show you the difference between using transparents on both the wing top and bottom and just the top. it's still a sharp looking plane but i find that the visibility is vastly improved after re-covering the bottom with opaque vs. transparent. just something to consider . . .
