over the top of the servo box there is to be a styrene lid, that will give access for wires etc around it it will have some railings if there is clearance between it and the sub cradle. on the front of it, a couple of doors, at the top of it, some vents, probably a set of read mushrooms, and at the fan tail side of it, perhaps a small deck with a door to it, thus that servo box will become part of the ship.
