China seems to find this stepped tapering of unmanned aircraft a good compromise bw range/weight & rear aspect stealth.

As a twin-engine aircraft, this is likely the upper limit of how large WZ-X can get. You need really high strength & light CFRP wings to have it be this long & thin at the ends. I'd imagine the leading edge will be installed w/ whole host of antennas for EW & ISR purposes. Which would naturally require different composite material (all extremely expensive) to be optimal.
