Thanks for all the responses. What I am trying to make is a miniture Sig Somethin Extra. PTERODACTYL, the wing tube is just a aluminum tube that goes through the center of the fuse and holds the two wing halves perpendicular to the plane ( it allows the wing to be center mounted and be able to be removed, it will also give me more roome inside of the center of the fuse to put my electronics) , the tube only extends into the first two ribs of the wing. BMatthews, I have been looking at a lot of the pictures on the internet and have seen a few from the top view and although the alerons are tapered, the wing is also slightly tapered. I was thinking of thinning down the wing some and building up the tail surfaces with sticks instead of solid material to make it lighter.

Heck, I know I am the one who asked the original question, and I thank all of you for your responses and I got quite a lesson, but probably more than I can understand. Thanks again for all the info. I will do as combatpigg suggests and get the plane under 28 oz and fly it.
