Yes WTF kit.
As for the gap it fits fine if you put the two pieces together (AB and Chest) but I see a lot of people where the chest overlaps above the ab top edge. Is it ok for it to sit onto- of the ab pierce or does it need the overlap?
Build Update: Helmet is done with electronics, in the process of trimming the last parts (most of which are done) - still have some legs to work on and things like trimming the belt parts.
