I did consider this, but really, what are the chances of them producing a UADF that has almost the exact same characteristics as the J-XD-S? They already have lower end ones that are almost like a mini-J-XDS already. The point of a high end UADF with high overlaps with the J-XD-S seems kinda of null in point to me.
Fair enough, but isn't this rather small for a full sized model? J-XDS should be about as long as J-20 but much wider, it is doubtful they'll be able to fit it on a flatbed without much disassembly.
Without other objects as a size reference I wouldn't be so sure about it being "small." We don't know the angle and position of the airframe relative to the camera, so that might just be some weird optical illusion.
Pretty much all the control surfaces. My guess is that engines are not there either.
size isn't really an issue because the thing doesn't need much space from the flatbed to sit on. See the trasportation of FC-31, most of it is hanging outside.
If this is the real plane then it is not that large at least cross sectional wise.
That's a FC-31
