Only fix one problem at a time. The most obvious is the CG issue. After you fix that fly it and see how it fly's. You will have other adjustments to make after that, such as elevator throw and trim. If you change more than one thing at a time you will be chasing problems until you eventually get it all balled up.
Cfircav8r's comments are spot on. Fix one thing at a time, in this case CG, then test.
Is it me, or are rctech's posts challenging to read? It's like I'm decoding a puzzle, and the diagrams were way too much info. [X(]
