Just finishing a GP Dazzler and am setting the surfaces. This is my first symmetrical wing, and I was wondering as to where neutral is on the wing. It is a little more bubblous (sic) on the top then the bottom. I just kinda eyeballed it and wondering if this is correct.

Looks pretty good what you did.
Interesting.... It looks like they took a symmetrical airfoil and flattened it on one side for ease of manufacturing. Do they advertise that as a symmetrical wing? It doesn't appear to be. Fact is, that in 3D it won't matter. But it is a bit funny.
With symmetrical wings, center the ailerons. Look directly from behind and line up the wing so you see the TE bisect the wing for symmetrical airfoil wings. For cambered wings, line the TE up with the bottom of the wing. Now try to see if the TE line looks straight compared to the wing. If you look closely at the pictures, you'll see the lineup for symmetrical in one picture and the lineup for cambered in the other. And you'll see that one wing is warped.
You use this eyeball technique to line up the ailerons and to sort out the warps.
