So based on their serial numbers LHXXXx07-16/25-29 and these images, there are already at least 10 in service!
And LHXXX is most likely LH953 from the 161st Air Assault Brigade at Xinxiang, CTC
Yup need to increase the Z 18 MTOW of 14 ton to higher number with empty weight of 7 ton. So it can carry max 5-6 ton. Can't even carry Mengshi. Not sure if dimension wise it can do that maybe old Mengshi I with 5Ton empty weight.This looks much better.
They need to make a triple engine with Z-20 engines.
