I just used a thin coat of epoxy and glued my stabs on both Integral in place.
I saw no reason to remove the Stab once it was installed. It also holds the stabs in place with less play and movement then the screw set up.

An alternative might be,to use a small bead of silicone as the glue----easier to cut through if you do have to remove a stab half at a later date.
(just saying this as a friend's elevator halves on his Integral were crushed recently--someone else's model ran into the Integral's nose,and it was pushed backwards into my flight box--which saved my Leviosa from a similar fate.)
