All those rectangular panels I assume are access panels.
I also assume that they will have some sort of a cladding to make it stealthy. Unless they go with a paint, how will they tackle those panels?
They could be panels where the metal is cut out and replaced with composite,making it lighter, tougher and more stealthy. Note that the peripheral angled parts could be metal and the flat bits composite.
The other question is, no matter what the Americans seem to be saying and doing, how important is radar stealth to a helicopter that will be directly exposed to enemy gunfire while approaching the area with stealthy nap-of-the-earth flying. Weight, noise and IR reductions would IMO be more profitable than a massive reduction in radar reflections - much of which comes from the rotors anyway rather than the body.
