I have to admit im struggling to understand where the issue stems from, the images are fairly clear and appear to be quite obvious in their differences where other circumstances (such as fuel load, braking stage, camera angle... all which have been used to dismiss the initial photos) wouldnt create the extremes shown in those photos.
But what i dont get is that the Red Bull & Ferrari wings are mounted in a significantly lower position to begin with, if you look at the center of the front wing, and compare its distance to the floor, and do the same for the endplates, that difference between teams is probably undetectable from photos that size. So this 'flex' issue surely cant be detectable on them.
The significant difference between the clearance isnt from flex, its the fact that the RBR & SF wing in its entirety is positioned a couple of inches lower than on the McLaren & Mercedes. That instantly makes the images a little misleading at first glance, and harder to see any irregularity between them when trying to account for that difference.
Obviously the location the wings are at is above board, so what is it about these photos that shows something which has Mclaren baffled by how they're achieving such results? All im seeing is wings mounted lower which makes them closer to the track, and that has sod all to do with flex. The endplates seem to be the focus, but are they refering to the amount of bow across the whole wing being unusually large under high speed, or something completely different? The most significant difference in the photos is how high the whole wing is mounted, and for images so small nothing seems to be too obvious.
I genuinely cant quite grasp which specific item the fuss is about, theres obviously something there as Whitmarsh & Lowe arent newbies and they seem stumpt to how its done in a legal capacity.
