I didn't want to make the whole deck removable so most of the internals are centred around the opening that the superstructure sits over, there are then a couple of hatches I've put in at the front and rear (that I'll blend in so they are not too obvious!) for access to the prop tubes, rudder and sound box. Access is still not the best now the deck is on though.
The servo morphs are very easy to set up, they give the turrets a nice slow traverse.
I also have an Artwox deck and lots of etched brass to fit. I bought the kit secondhand (but unstarted) and she came with a set of Steve Nuttall turned main gun barrels, I've since bought turned barrels for the other guns from GPM in Poland.
