that made me laugh out loud i certainly wouldnt call myself a master of anything, except maybe procrastination (no one can put something off better than i can!). but a master of micro building, well, i wouldnt go that far personally, i've just been doing it longer than some. in comparison to MANY other people i talk to, i'm a rank newbie as well, even after a year or so at doing this. micro planes are a completely differant breed than any other RC planes, they require a lot more attention to detail. some things that you'd never notice, and would never affect a normal size RC plane, will cause major havoc with a micro plane. its all in the details

anywho, i'd say your CG is off, as you said. with that much additional wing area and lift, its no wonder, i can only imagine how easily it can climb. it looks pretty cool too, i like the look of the stubby bottom wings with the huge wing above it. i'd start adding weight to the nose, or put the battery further forward. even after putting the cell forward, you may still need extra weight to balance things out, but the extra weight will be worth it, a well balanced plane controlls a lot better. i attatched a picture of how i modified my AA to access the lipo for charging and CG movement, hope it helps.

if the plane spirals down without throttle, it sounds like one of the wings or tail feathers is out of alignment. look at the plane from directly in front of it, make sure the wings you added are symetrical, and that the leading edge and trailing edge of the wings are similar. with that much wing with so little weight, it wouldnt take much of a bend here or there on the wing to cause it to turn and dive. adding some extentions to the tail feathers probably wouldnt hurt either, it may not need it, but there's only one way to find out.

as for moving the motors out further, you dont need to add extra wire. the motors have quite long leads on them. i cant remember off hand if you can pull the wire through the frame and wing while its still all together or not though. also, if you point the motors in a little bit, it should help the turning (looking at the plane from above, the motors and props should point in towards the tail).

here's hoping for calm winds!
