All of my servos seem to have been working just fine over the past few months and they all function properly after my range checks.

I somehow doubt it was your cg. I also have this plane and I balanced it as you did and since then have played around with the cg by moving the battery or using a heavier battery without ever measuring teh cg again. I was happy to do this as the plane exhibited no negative tendencies, just the usual things. The more rearward cg definately increased elevator sensitivity and made landings harder, but had no uncontrollable stability issues at all. How about some kind of airframe issue, like a bent wing tube...
