Looks like I needed to re-size my photos!
So, part of bashing this kit is lengthening the wing from 61" to 67", and lucky for me, my LHS carries 48" balsa, so I won't have to splice any spars or trailing edges. I laid out the wing plan to have 2 1/2" rib spacing from the center out to the nacelle, the 3" out to the tip. I needed to cut out a couple of extra ribs, then weighed them all so I could bias the weight to the left wing to counter the offset weight of the engines and their pipes.
