sure thats true Phil.
The vents must be cutted and placed before one by one on a flat PE with precise distance preholed lines and placed at the correct angle (working with superglue non so easy, LOL) then the little part group must be placed under thick bonnet,where thickness is around 3 mm. I closed everything on the internal side with milliput ang superglue with filler.
Before doing it was also thinking to use only the vents without the base, but such way is nearly impossible for me to fix theme in correct position, same distance and correct angle too (again with istant glue). add to this bonnet in such point is curved on 2 angles, and vents themself are curved too. LOL
think really this was the only way to make theme,asnd also for HD there is no other way to do it with a resin model kit.
On istruction sheet there is anything about this, of course, but also this is typical with those kinda models
compromises.....compromises..
