NO!!!

That is one way to get CA hinges to fail!!!!

The hinge MUST be inserted into BOTH sides (Wing AND Aileron - or - Stab AND Elevator) BEFORE applying ANY CA!!!

The reason for this is that THIN CA (And when working with CA Hinges, THIN is the ONLY kind that should be used) works on a capillary principle. That means it needs a POROUS surface to wick into.

If you insert half of the hinge into the aileron and apply CA, the CA will wick into the pores of the entire hinge sealing any pores in the exposed side. Now when you put that side into the wing, the CA doesn't have a good surface to grab on to.
