RE: Unequal winghalfs
Nope, the right and lefthand wing halves are pretty well parallel and right next to one another. It shrinkage were to happen, it would then affect them both. The spacing of the ribs is about 1/32 per greater on one half than the other.
There isn't any downthrust or right thrust indicated for the engines. Wonder if the unequal length of wing halves was one way to adjust for this.
