>>6397928I'm not so sure about that though. I looked at how both wings shifted in the trailers and they clearly functioned/moved very differently.
The smaller wings of the first set have the turbines deep set into the actual wing structure, in which every turn made by the turbines would leave a huge empty gap under each wing. With the bigger wings in the second set, the turbines move independently from the larger wing structure, as if they're attached to a second pair of smaller "wings" at the back (similar to the BAF set).
Beyond that, the overall volume of the second set is much too large for them to simply be caused by shifting metal plates with how the "feathers" are clearly positioned far away from the turbines. Compare that to the the smaller set which has the "feathers" clearly fixed at the edge of the rims holding the turbines and how they clearly can't expand further out. Also the second set has the blatantly large "tail" backpack running down behind Vulture's body as if the entire wing structure is one whole unit (again like the BAF). By comparison, the first set has a huge segmented gap separating the pair of wings with no "tail" backpack in sight.
Admittedly, it gives me comfort that the BAF wings might not actually be that far off from how they'll look in the film, not to mention how they could very well be based on an upgraded design that Toomes might use in the climax. The only thing that looks to be blatantly missing with the actual Vulture figure is that it looks like he's meant to have a metal armature for each arm in the film, while also having "Shocker"-styled attachments held in each hand.
