I have the cross grain cut and edge glued I had to use 3" balsa as our LHS selection of balsa is all messed up. Wrong sizes everywhere. The outside ply with the grain running the long was is of 4" wide balsa and I think it will be ok. The nacelles width is 3" inches. And I have a form, almost gave up on that until I saw an empty quart bottle of Wildcat it is almost a perfect fit.

What's next?
