Some ARF supplied CA hinges are wierd.lol
They don't have fiber like coating on them like the GP hinges...so I drill tooth picks
or pins into them after installation just to make sure.

I opt to use epoxy..becuase I'm too slow
Plus I don't like gaps, and i can makesure the hinges dosn't get bunched up in the slot.

Plus if I made the slot wider then the thin CA hinges...CA is not going to make up for the gap.
So, i use epoxy to make up for the gap.
It's not was noticable on the control surface..but you'll notice dimples on the wing where
the hinges are.

Sometimes I'll just CA the hinge to the control surface one at a time. But always
use epoxy to glue the control surfaces to the wing becuase I like to makesure the tips match.lol

It's not as if I'm going to go flying 1 hour after I glue the control surface.lol
The next day, I'll yank the heck out of the control surface.
