it's okey to ca the first part.
but i'm not fast enough for the second.

plus oil will break up CA later, espacially on the tail feathers or
on the hinges closest to the wing's root.

CA will also wick into the flexing part of the CA hinge..making it hard
and brittle. a rip or crack will develope later.
i draw a center line on the hinge with crayons to prevent epoxy from
sticking to the flex piont and clean off the epoxy as much as i can.

plus it also depends on how you cut the slot. if you used an xacto,
sometimes there's thin slices of wood in the slot. makesure you clean that out
or the hinge will only stick to that thin loose slice.

to put my mind at rest. i drilled tooth picks in the hings TE and control surface.
this will prevent any put outs.

i also seal the hing gap lines between TE and control surface with covering film
on top and bottom or both sides for the rear stabs.
it dose two things....prevent air leaks to the control surfaces
and prevents oil to the hinges
