Great advice.

But I'm wondering... considering that I'm adding about 3 grams to both the tail and wing, I don't think I would be changing the CG enough to notice it even on trying to rebalance.

But, you are correct! Any major repairs where your adding anyting more than what would already be there would change it. Fortunately for my brother, he's got a brother that doesn't glob in the epoxy into a lump... just enough to hold the pieces together and a smidge more.

Thanks for the great advice!!!
