Laurent, yes they correspond to something that is not correct on the subjects. Like, e.g. this type of Pito tube is not for PD/PDS but for P.
But again, these are CAD drawings and may be KH showed all variants they want to model in future. Who knows. Otherwise why would there be bombs on
PD/PDS?
As to the help to a designer.. Well.. you are right.. someone should sit next to him all the time. We can see an example of GWH MiG-29 where Alexander Drannikov who mentioned on the instruction as advisor for the model now says that lots of his comments on a CAD drawings and master were ignored. And he has been 3D modelling MiG-29, Su-27 and other subjects for years with years of field research etc...
So, I guess you are right.. KH is in hurry to be the first and I can't really blame them but again it would be great to listen when there is someone to listen to and adjust accordingly. There was a plenty of time and there are lots of experts. What could be easier - find an expert, sign NDA and exploit them to achieve the best result.
