Just a question again due to an observation:
All these new Z-10H called aircraft are a bit different to the known serial aircraft: they have again the AH-64-like lower sensor + the bigger upper one, they all have the earlier prototype-style tail + rear gear and the old style canopy glass shaping. Some post are assuming that they have an uprated engine and are therefore featuring again the old airframe.
Especially one aircraft numbered in red a few day ago brought me now to the idea that these are maybe more likely not new birds but older original-style pre-serial airframes or even prototypes delivered to an operational unit.
IMO it simply does not make any sense to have the original configuration, that was too heavy due to a limited engine output ... then to redesign the fuselage in parts, the tail + gear as well as the canopy to save weight ... build several (and we speak of really many) of these weight-reduced serial standard airframes and now suddenly with reportedly a new engine all the weight reductions were left and the old heavy airframe is used again.
IMO it would simply make much more sense to retain the already proven standard airframe and simply add the new engine !
As such I'm now almost sure that they are in fact not a new build Z-10A, H or K version but simply a few refurbished prototypes and pre-serials modified to be assigned to an operational unit.
For comparison, the first two images are the said to be "new" configuration ... the third the standard serial one.
Just my 2 Cents.
