New Picture of Fc-1

New color image of Fc-1 can be seen here:

what I have noticed about Fc-1 prototype pictures seen so far is that they all clearly show wing fences. Wing fences were not seen on models of Fc-1. I thought that Fc-1 wings looked the same as F-16 wings, but F-16 wings don’t have fences.

Wing fences are used to prevent boundary separation on swept wings, though wing fences are not that common on new designs any more.

Are the wings of Fc-1 not as advanced as F-16? Does any one know the significance of Fc-1 having wing design that uses fences?
