Looking at the front on pictures of the Airbus A380, it appears they have alot of droop. Does anybody know if the wing tanks are loaded during the rool out. If they are not I wonder how much droop they will have if loaded.

Could be partially distorted by the fisheye effect of the camera ... it appears that they used a wide angle lens.
Also, the wings seem to have a rather steep initial incline near the fuselage. That could be used as a neat design trick to get the maximum strength out of the minimum mass. If that is true, the wing would appear to be permanently flexed downward, as you noticed in the picture

I think it is an illusion caused by the angle of the photo and the wide angle lens. I do not think the wings would be sagging before loading and I do not think they loaded them for the roll out. The key words here are "I think", only an opinion.

I don't think it is an illusion. I would hazard a guess that the wings are pretty much how they are represented in the picture, and i'm pretty sure most large new aircraft that have wings that look similar when unladen. You take a look next time when you're on a widebody airliner at the wings in flight, they will look kind of flat with quite a bit of flex in a concave shape. When you land, when the fuel tanks are empty the wing will look very similar to this, due to there being no forces of lift or the weight of fuel in the tanks to make them appear straighter. They are not drooping in the picture, they are bending upwards. With fuel in the tanks i'm sure they'll be more horizontal.

i wonder if the wings will flex as much as the 747, 777, 767, A330..etc. or maybe it will be like the DC-10 and have very low flex. a plane that size would be very awesome to see if the wings could flex over 20 feet like the 777 on take-off!!
