It looks to me like the blades do not have accomodatin for pitch changes either. The rectangular fitting at the root end cannot rotate about the centre of the hub in any way that I can see.
Are we seeing the first of the "intelligent" blades that will accomodate pitch changes along their length by variable twisting? Interesting times.
