Wrong calculations.

It seems that my way of figuring things wasn't quite right. The wing area I was hoping for won't come out using my 109 figure. The person that designed the original I was trying to enlarge says my figure is 665 sq. in. not 610.. He agreed to lazer cut me some parts for the right size and sent me the plans. While waiting for them to arrive I started on the larger model. The plans answered some questions on where the parts go and how the wing should be constructed. Anyway I have the wing half built and the tail built and some of the nose pieces. I need some 1/2 inch balsa to make the fuselage and that shipped today.
