Be sure the blades are cleaned of any grease etc. and then take some heavy grit sandpaper and rough up the portion going into the wing long ways with the blade. I use 80 grit at least. You want to have some deep scratches for the epoxy to bind to. Use a very long cure time epoxy (at least an hour) more is better. I even test mix a batch and let it cure to be sure the mix is good before committing to the real thing. After mixing the epoxy I stand the wing on its tip and pour some epoxy in the box and use a thin wire or card stock to be sure the box is coated inside on all surfaces. I cover the blade on the sanded area with epoxy also. Now slowly work the blade into the box and be sure a trapped air bubble doesn't push it back out. If you need to align it as it sets up, then place plastic wrap on the wing root of the fuselage and the wing itself (with small slits for the blade) then assemble the wing to the fuselage and tape or block in place until cured. I built my old Multiplex DG 600 this way and it is more than sufficient. I don't think drilling holes in the blade is needed and some of the blades use hardened material that would be tough to drill anyway.
