Yes it's a ARF, and I usually try to improve anything I can when I build them without butchering the plane if I can help it.

The ailerons were epoxied in at the factory with the good nylon hinges. I gave them a good pull and one was well glued, the other aileron came out, I quickly re-epoxied and re-installed the loose aileron.

I'm not sure if the control sufaces are solid balsa or not, they are all pre-covered.

What I am thinking of doing was to use some brand new Nylon Hanger 9 Control Horns (with the 3 screw holes) sand the bottom a little, place them on the control surface, outline them with a pencil, cut the fabric away, hand drill the holes 1/16, put a few drops of thin CA in the holes and epoxy the bottom of the control horns on the control surface, and by using the #2x3/8 Button Head screws, tighten everything down.

Does epoxy soak deep into balsa making it a hard surface like the CA hardens the holes for the screws?

The ARF is a VQ Warbird, the Me-108.

I thank you all for your thoughts and quick response, I like everyones answer so far, I just need to make the right decision.
