No need to be sorry and six ounces is still not out of reason but but add the weight in a temporary fashion. The very first thing you need to do is go fly the airplane once more after you balanced truly at the quarter chord (25%].
Now after doing that I am betting two burned out glow plugs aginst a Stale Glazed Donut that you come back talking about a what a nice flying airplane it is. And then we can talk about a few ways to eliminate that little bit of extra weight and without a huge fuss.
