This is the one I have. I'm thinking to cut lightening holes in the solid 3/16 balsa horizontal and vert stabs to help the tail heavy situation done properly they should not weaken them much, now to figure the correct size and placement? I hate to add weight to an already brick heavy plane.
On a brighter note I have my old Lou Andrew A Ray about ready to fly again. wish I had the original wing with ailerons .
